ITEM 1.  BUSINESS.

     We  discover,  develop,  manufacture and  market  companion  animal  health
products.   We  have  a  sophisticated scientific  effort  devoted  to  applying
biotechnology to create a broad range of pharmaceutical, vaccine and  diagnostic
products  for the large and growing companion animal health market.  In addition
to  our pharmaceutical, vaccine and diagnostic products, we also sell veterinary
diagnostic  and patient monitoring instruments and offer diagnostic services  in
the  United  States  and  Europe  to veterinarians.  Our  primary  manufacturing
subsidiary,  Diamond Animal Health, Inc., or Diamond, manufactures some  of  our
companion  animal  products and food animal vaccine and pharmaceutical  products
which are marketed and distributed by third parties.

     Our  principal executive offices are located at 1613 Prospect Parkway, Fort
Collins,  Colorado  80525 and our telephone number is (970) 493-7272.   We  were
incorporated in California in 1988.  We reincorporated in Delaware in 1997.

     ALLERCEPT,  ALLERCEPT E-SCREEN, FLU AVERT I.N., HESKA,  VET/OX,  VET/E-Sig,
VET/ECG,  VET/IV, CHEM-ELITE and SOLO STEP are trademarks of Heska  Corporation.
This 10-K also refers to trademarks and trade names of other organizations.

ANIMAL HEALTH PRODUCTS

     We  presently sell a variety of companion animal health products, among the
most significant of which are the following.

DIAGNOSTICS

Heartworm Diagnostics

     Heartworm  infections  of  dogs  and  cats  are  caused  by  the  parasite,
Dirofilaria immitis.  This parasitic worm is transmitted in larval form to  dogs
and  cats  through the bite of an infected mosquito.  Larvae develop into  adult
worms which live in the pulmonary arteries and heart of the host, where they can
cause serious cardiovascular, pulmonary, liver and kidney disease.

     In  1997,  we developed a diagnostic test for heartworm infection in  dogs.
This  test uses monoclonal antibodies reactive with heartworm antigens to detect
the  presence of these antigens in the blood of the infected dog.  This test was
first  offered  through  our own veterinary diagnostic  laboratory.   A  simple,
rapid,  and  easy to use point-of-care version of this test, SOLO STEP  CH,  was
introduced in Italy in 1998.  In January 1999, we received regulatory  clearance
to  sell  SOLO STEP CH in the United States and introduced this product  in  the
United  States  shortly  thereafter.   In March  2000,  we  received  regulatory
clearance to sell a batch test version of this product, SOLO STEP CH Batch  Test
Strips, and introduced this product in the United States shortly thereafter.

     In  1997,  we introduced a new test in our veterinary diagnostic laboratory
for  heartworm infections of cats which allowed veterinarians for the first time
to  accurately  establish the prevalence of feline heartworm exposure  in  their
practices.    This  test  is  highly  sensitive  and  accurate,  and  identifies
antibodies  in  cat serum that react with a recombinant heartworm  antigen.   In
1997, we introduced a rapid, point-of-care version of this test in Italy.  After
receiving   regulatory  clearance,  we  introduced  this  point-of-care   feline
heartworm test, SOLO STEP FH, in the United States in 1998.

Allergy

     Allergy  is  common  in companion animals, and it is  estimated  to  affect
approximately  10% to 15% of dogs.  Clinical symptoms of allergy  are  variable,
but  are  often manifested as persistent and serious skin disease  in  dogs  and
cats.   Clinical management of allergic disease is problematic, as there  are  a
large number of allergens that may give rise to these conditions.  Although skin
testing is often regarded as the most accurate diagnostic procedure, such  tests
are   painful,   subjective  and  inconvenient.   The   effectiveness   of   the
immunotherapy that is prescribed to treat allergic disease is inherently limited
by inaccuracies in the diagnostic process.

     We  have developed the HESKA ALLERCEPT Definitive Allergen Panels,  a  more
accurate  in  vitro  technology, to detect IgE, the antibody  involved  in  most
allergic  reactions.   This  technology permits the design  of  tests  that,  in
contrast to other in vitro tests, more accurately identify the animal's allergic
responses  to particular allergens.  During 1997, we adapted this technology  to
our  canine  allergy  tests.  The ALLERCEPT Definitive Allergen  Panels  use   a
recombinant  version  of  the  natural IgE  receptor  to  screen  the  serum  of
potentially  allergic  animals  for  IgE  directed  against  a  panel  of  known
allergens.   A  typical test panel consists primarily of various pollen,  grass,
mold and insect allergens.

     We  have  also  developed the HESKA ALLERCEPT E-SCREEN Test,  a  rapid  and
highly  accurate screen for certain antibodies commonly associated with allergic
disease.   This product, which utilizes our proprietary patented technology,  is
designed  to  enable  veterinarians to do point-of-care  screens  of  dogs  with
allergic  symptoms.   In January 2001, we entered into a distribution  agreement
with  Novartis Animal Health granting exculsive distribution rights for  the  E-
Screen Test product in Europe.

VACCINES

Equine Influenza Vaccine

     Equine  influenza  is a common viral disease of horses and  is  similar  to
human  influenza.   This disease poses a significant risk to the  estimated  six
million  horses  in the United States.  Infected horses have severe  respiratory
disease  and diminished performance for an extended period following  infection.
We  believe  that  approximately half of the six million horses  in  the  United
States  receive  vaccination.  Most competitive equine  influenza  vaccines  are
administered  as  a  component of a multi-purpose vaccine, intended  to  provide
protection   against  multiple  infectious  diseases.   Industry  sources   have
estimated the total U.S. equine vaccine market at $50 million.  We believe  that
other currently available vaccines for equine influenza are of limited efficacy.
We  have  developed a unique vaccine for equine influenza, our  FLU  AVERT  I.N.
vaccine,  which  we  believe  has improved efficacy  and  duration  of  immunity
compared  to  existing  products.  This product was  approved  by  the  USDA  in
November  1999 and was first sold to veterinarians in December 1999.   In  March
2001, we granted Novartis Animal Health Canada exclusive distribution rights for
FLU AVERT I.N. vaccine in Canada.

Allergy Immunotherapy

     Veterinarians who use our in vitro allergy testing services often  purchase
immunotherapy  treatment  sets for those animals  with  positive  test  results.
These  prescription treatment sets are formulated specifically for each allergic
animal and contain only the allergens to which the animal has significant levels
of  IgE  antibodies.  The prescription formulations are administered in a series
of  injections,  with doses increasing over several months,  to  ameliorate  the
allergic condition of the animal.  Immunotherapy is generally continued  for  an
extended  time.   We  offer  both  canine  and  feline  immunotherapy  treatment
products.

Feline Respiratory Disease

     In  1997,  we  introduced  in the United States a three-way  modified  live
vaccine  (HESKA  Trivalent Intranasal/Intraocular Vaccine) for  the  three  most
common   viral  diseases  of  cats:   calicivirus,  rhinotracheitis  virus   and
panleukopenia virus.  This vaccine is administered without needle  injection  by
dropping the liquid preparation into the eyes and nostrils of cats.  While there
is  one  competitive  non-injectable  two-way  vaccine,  all  other  competitive
products  are injectable formulations.  The use of injectable vaccines  in  cats
has  become controversial due to the frequency of injection site-associated side
effects.   The  most serious of these side effects are injection site  sarcomas,
tumors  which,  if  untreated,  are nearly always  fatal.   Our  vaccines  avoid
injection site side effects and we believe they are very efficacious.

PHARMACEUTICALS

Canine Thyroid Supplement

     Canine  hypothyroidism  is  a serious disease that  is  usually  caused  by
abnormalities of the thyroid gland.  It is estimated that 3% to 4% of  all  dogs
require thyroid hormone replacement therapy.  Common clinical signs include dry,
coarse, thin hair, possibly with patches of hair loss and pigment changes.   The
disease can affect multiple organ systems and cause recurrent infections.

     In   1997,   we   introduced  a  chewable  tablet  for  the  treatment   of
hypothyroidism in dogs in the United States.  These chewable tablets, which  are
administered  daily  for  the life of the dog, provide levothyroxine  sodium,  a
replacement therapy for the hormone normally produced by the dog.

Nutritional Supplements

     Arising  partly  from  our allergy expertise, in  1998,  we  developed  and
introduced  in  the  United  States a novel fatty acid  supplement,  HESKA  F.A.
Granules.  The source of the fatty acids in this product, flaxseed oil, leads to
high  omega-3:omega-6 ratios of fatty acids.  Diets high in omega-3 fatty  acids
are  believed to lead to lower levels of inflammatory mediators.  The HESKA F.A.
Granules  include  vitamins and are formulated in a palatable flavor  base  that
makes the product convenient and easy to administer.

MEDICAL INSTRUMENTS

     We  offer  a  broad  line of veterinary diagnostic,  monitoring  and  other
instruments  which  are described below.  We entered this line  of  business  in
March  1998, when we acquired a manufacturer and marketer of patient  monitoring
and  diagnostic  instruments.   Following that  acquisition,  we  completed  the
development  of  various other instruments and entered into agreements  for  the
distribution of additional instruments to veterinarians.

Diagnostic Instruments

     Our  line  of diagnostic instruments includes the i-STAT Portable  Clinical
Analyzer,  a  hand-held, portable clinical analyzer that  provides  quick,  easy
analysis of blood gases and other key analytes, such
as  sodium,  potassium and glucose, with whole blood.  This past  year  we  have
introduced  new  i-STAT capability for measuring additional blood  analytes  and
expanding  the versatility of the instrument for veterinarians.  In  the  United
States we also market the Heska Vet Diff ABC Hematology Analyzer, an easy to use
blood analyzer that measures such key parameters as white blood cell count,  red
blood  cell  count, platelet count and hemoglobin levels in  animals.   We  also
offer  the Reflovet Clinical Analyzer, an easy to operate, cost effective  blood
chemistry analyzer that measures a broad range of animal blood analytes, such as
amylase, creatinine, uric acid, bilirubin and glucose.  Consumable supplies  for
the  i-STAT,  Vet  ABC  Hematology Analyzer and Reflovet are  also  provided  to
veterinarians through Heska sales and distribution channels.

     In  January  2001,  we  announced the introduction of  our  new  Chem-Elite
Advanced   Chemistry   System.   The  Chem-Elite  System is  a   micro-processor
controlled,  programmable liquid chemistry analyzer designed  for  use  in  high
volume  veterinary  practices.   It  gives  veterinarians  the  ability  to  run
individual tests, pre-programmed batteries of tests or customized profiles.

     We  also  announced  the  introduction in March 2001  of  the  SPOTCHEM  EZ
Automated Chemistry Analyzer.  The SPOTCHEM EZ is a compact desktop system  used
to  measure  all common blood chemistry components that are vital to  veterinary
medical diagnosis.  It provides veterinarians with an easy to use, flexible  and
economical in-clinic chemistry system.

Monitoring and Other Instruments

     The  use by veterinarians of the types of patient monitoring products  that
are  taken  for granted in human medicine is becoming the state of  the  art  in
companion  animal health.  The centerpiece of our monitoring instrument  product
line  are  oxygen  saturation  monitors designed for  monitoring  animals  under
anesthesia: the VET/OX 4404 monitor and the VET/OX 4800 monitor, each  of  which
includes  a variety of additional monitoring parameters, such as pulse rate  and
strength,  body  temperature,  respiration and  ECG.   We  offer  a  proprietary
esophageal  ECG  sensor, VET/E-Sig probe, for monitoring  ECG,  temperature  and
heart and breath sounds of anesthetized dogs.  Our monitoring line also includes
the  VET/ECG  2000,  a  hand-held ECG monitor.  We also  offer  the  VET/IV  2.2
infusion pump, a compact, affordable IV pump that allows veterinarians to easily
provide regulated infusion of blood or nutritional products for their patients.

VETERINARY DIAGNOSTIC LABORATORY

     We  have  a  veterinary diagnostic laboratory at our Fort Collins facility.
This diagnostic laboratory currently offers our allergy diagnostics, canine  and
feline heartworm diagnostics and flea bite allergy assays, in addition to  other
diagnostic  services.   Our  Fort Collins veterinary  diagnostic  laboratory  is
currently  staffed  by medical technologists experienced in animal  disease  and
several additional technical staff.

     We intend to continue to use our Fort Collins diagnostic laboratory both as
a  stand-alone service center for our customers and as an adjunct to our product
development efforts.  Many of the assays which we intend to develop in a  point-
of-care  format  are initially validated and made available  in  the  veterinary
diagnostic   laboratory  and  will  also  remain  available  there   after   the
introduction of the analogous point-of-care test.

FOOD ANIMAL PRODUCTS

     In addition to manufacturing companion animal health products for marketing
and  sale  by  Heska, Diamond has completed the development of new  food  animal
vaccines  that were licensed by the USDA in the United States in 1998 and  1999.
Diamond  has  entered into an agreement with a food animal products distributor,
Agri  Laboratories, Ltd., or AgriLabs, for the exclusive marketing and  sale  of
these  vaccines worldwide.  AgriLabs currently has an arrangement with Intervet,
International  B.V.,  a  division of Akzo Nobel, for the distribution  of  these
vaccines worldwide.  Diamond is the sole manufacturer of these products.

     Diamond  also  manufactures vaccine products for a number of  other  animal
health  companies.   This activity ranges from providing bulk  vaccine  antigens
which are included in the vaccines which are manufactured by other companies  to
filling  and  finishing  final products using bulk antigens  provided  by  other
animal health companies.

PRODUCT CREATION

     We  are  committed  to creating innovative products to address  significant
unmet  health  needs  of  companion animals.  We create  products  both  through
internal research and development and through external collaborations.  Internal
research  is  managed  by  multidisciplinary  product-associated  project  teams
consisting  of  veterinarians, biologists, molecular  and  cellular  biologists,
biochemists  and  immunologists.  We believe  that  we  have  one  of  the  most
sophisticated  scientific efforts in the world devoted to applying biotechnology
to the creation of companion animal products.

     We  are  also  committed to identifying external product opportunities  and
creating  business  and technical collaborations that lead to  the  creation  of
other products.  We believe that our active participation in scientific networks
and  our  reputation for investing in research enhances our ability  to  acquire
external product opportunities.

     Our product pipeline currently includes numerous products in various stages
of  development.   Products  under  development  include  several  point-of-care
diagnostic  products, vaccines for infectious diseases in cats, dogs and  horses
and  pharmaceutical  products  for  allergy,  cancer,  osteoarthritis  and  flea
control.

     The  vast  majority  of  all  our research and  development  resources  are
directed  toward  the development of new companion animal health  products.   We
incurred expenses of $14.9 million, $17.0 million and $25.1 million in the years
ended  December 31, 2000, 1999 and 1998, respectively in support of our research
and development activities.

SALES AND MARKETING

     We  presently  market  our  products  in  the  United  States  directly  to
veterinarians  through  the  use  of  our field  sales  force,  inside  customer
service/tele-sales force and veterinary distributors acting  as  contract  sales
agents.   As  of  December  31,  2000,  we  had  approximately  35  field  sales
representatives  and field sales supervisors and 13 customer  service/tele-sales
representatives   and   supervisors.   We  have  entered   into   sales   agency
relationships with 16 veterinary distributors and six direct sales distributors,
although some of these distributors do not sell all of our products.  In October
1999,  we  entered  into an agreement with a third party to provide  a  contract
sales  force  for  the  sale  of  our products to  equine  veterinarians.   This
agreement  was  terminated  in November 2000.  Internationally,  we  market  our
products to veterinarians primarily through distributors.

     We estimate that there are approximately 30,000 veterinarians in the United
States whose practices are devoted principally to small animal medicine.   Those
veterinarians practice in approximately 20,000 clinics in the United States.  We
market our products to these clinics primarily through the use of our field  and
telephone sales force, sales agents, direct sales distributors, trade shows  and
print  advertising.  During the past year, we sold our products to approximately
14,000 such clinics in the United States.

     Some  of  the  products which we have under research  and  development,  if
completed,  may be marketed partially or wholly by third parties  with  whom  we
have collaborative agreements.

MANUFACTURING

     Our  products  are  manufactured  by our  Fort  Collins,  Diamond  and  CMG
facilities and/or by third party manufacturers.  Diamond's facility  is  a  USDA
and  FDA  licensed biological and pharmaceutical manufacturing facility  in  Des
Moines,  Iowa.  We expect that we will manufacture most or all of our biological
products  at  this facility, as well as most or all of our recombinant  proteins
and  other  proprietary reagents for our diagnostic products.  CMG  manufactures
its  allergy  diagnostic  products  at its facility  in  Fribourg,  Switzerland.
Diamond's facility is subject to regulation and inspection by the USDA  and  the
FDA.  Our heartworm point-of-care diagnostic products are manufactured by Quidel
Corporation and Diamond.  Our canine and feline allergy immunotherapy  treatment
products are manufactured by Centaq, Inc.  Our veterinary diagnostic and patient
monitoring  instruments,  including our clinical and  hematology  analyzers  and
veterinary sensors, are manufactured by third party manufacturers.

     In addition to manufacturing our proprietary products, Diamond manufactures
animal  health  vaccine  products for marketing and  sale  by  other  companies.
Diamond currently has the capacity to manufacture more than 50 million doses  of
vaccine  each  year.  Diamond's customers purchase products  in  both  bulk  and
finished  format,  and  Diamond performs all phases of manufacturing,  including
growth of the active bacterial and viral agents, sterile filling, lyophilization
and  packaging.   In  addition, Diamond offers to support its customers  through
research  services,  regulatory  compliance  services,  validation  support  and
distribution services.

COLLABORATIVE AGREEMENTS

Novartis

     We  have entered into several collaborative agreements with Novartis Animal
Health.   Novartis has various rights to manufacture and market any flea control
vaccine  or  feline  heartworm  control vaccine product  developed  by  us.   In
addition, we entered into a screening and development agreement under  which  we
may  undertake joint research and development activities in various  fields  and
under  which  Novartis  has the right to use certain  of  our  materials  on  an
exclusive or co-exclusive basis.  We also entered into a right of first  refusal
agreement  under  which, prior to granting licenses to any third  party  to  any
products  or technology developed or acquired by us for either companion  animal
or  food  animal  applications, we must first notify  and  offer  Novartis  such
rights.   The  screening and development agreement and right  of  first  refusal
agreement  each terminate in 2005. We also entered into additional research  and
development agreements in specific areas.

     Novartis  has the exclusive right to distribute certain of our products  in
Japan,  including our in-clinic feline and canine heartworm diagnostic  products
and  feline viral vaccines, upon obtaining regulatory approval in Japan for such
products.   Novartis also granted us a right of first refusal  to  evaluate  for
possible  development  and marketing worldwide various new product  technologies
for  the veterinary market as they may become available from Novartis.  Novartis
also has the exclusive right to distribute our ALLERCEPT E-Screen test in Europe
and our FLU AVERT I.N. equine influenza vaccine in Canada.


Ralston Purina Company

     We  have  a  strategic  alliance with Ralston Purina Company,  the  world's
largest manufacturer of dry dog foods and dry and soft-moist cat foods.  Ralston
Purina  holds  exclusive  rights  to  license  our  discoveries,  know-how   and
technologies  for  innovative diets for dogs and cats.  The first  product  from
this strategic alliance was introduced by Ralston Purina in July 2000.  This new
product  is  a specialty diet for the nutritional management of feline  diabetes
mellitus.  We receive a royalty from Ralston Purina on sales of this product.

INTELLECTUAL PROPERTY

     We  believe  that  patents, trademarks, copyrights  and  other  proprietary
rights  are  important to our business.  We also rely upon trade secrets,  know-
how, continuing technological innovations and licensing opportunities to develop
and maintain our competitive position.

     We  actively  seek patent protection both in the United States and  abroad.
As  of  December 31, 2000, we owned, co-owned or had rights to 105  issued  U.S.
patents  and  127  pending U.S. patent applications.  Our  issued  U.S.  patents
primarily  relate  to allergy, flea control, heartworm, diagnostics  or  vaccine
delivery  technologies.   Our pending patent applications  primarily  relate  to
allergy,  flea  control,  heartworm,  diagnostics,  nutrition,  cancer   vaccine
delivery  or  medical  instrument technologies.  Applications  corresponding  to
pending U.S. applications have been or will be filed in other countries.

     We  also  have  obtained exclusive and non-exclusive licenses for  numerous
other patents held by academic institutions and biotechnology and pharmaceutical
companies.   The  proprietary  technologies of Diamond  and  CMG  are  primarily
protected  through trade secret protection of, for example, their  manufacturing
processes.  In general, the intellectual property of Diamond's customers belongs
to such customers.

GOVERNMENT REGULATION

     Most of our products being developed will require licensing or approval  by
a  governmental  agency  before marketing.  In the United  States,  governmental
regulation of animal health products is primarily provided by two agencies:  the
USDA  and  the  FDA.  Vaccines  and point-of-care diagnostics  for  animals  are
considered  veterinary biologics and are regulated by the Center for  Veterinary
Biologics, or CVB, of the USDA under the auspices of the Virus-Serum-Toxin  Act.
Alternatively,  animal drugs, which generally include all  synthetic  compounds,
are  approved  and monitored by the Center for Veterinary Medicine  of  the  FDA
under  the auspices of the Federal Food, Drug and Cosmetic Act.  A third agency,
the  Environmental  Protection Agency, has jurisdiction  over  various  products
applied topically to animals or to premises to control external parasites.

     Industry  data  indicates  that  it  takes  approximately  four  years  and
$1.0  million to license a conventional vaccine for animals from basic  research
through  licensing.   In  contrast to vaccines,  point-of-care  diagnostics  can
typically be licensed by the USDA in about a year, with considerably less  cost.
However,  vaccines or diagnostics that use innovative materials  such  as  those
resulting  from  recombinant DNA technology usually require additional  time  to
license.   The  USDA licensing process involves the submission of  several  data
packages.   These  packages  include information on  how  the  product  will  be
manufactured,  information  on  the  efficacy  and  safety  of  the  product  in
laboratory animal studies and information on performance of the product in field
conditions.

     Industry  data indicates that it takes about 11 years and $5.5  million  to
develop  a  new  drug  for  animals, from commencement  of  research  to  market
introduction.   Of  this  time, approximately three years  is  spent  in  animal
studies  and  regulatory review process.  However, unlike human  drugs,  neither
preclinical  studies  nor  a sequential phase system of  studies  are  required.
Rather,  for  animal  drugs, studies for safety and efficacy  may  be  conducted
immediately  in the species for which the drug is intended.  Thus, there  is  no
required  phased evaluation of drug performance, and the Center  for  Veterinary
Medicine  will review data at appropriate times in the drug development process.
In  addition,  the time and cost for developing companion animal  drugs  may  be
significantly  less than for drugs for food producing animals,  as  food  safety
issues relating to tissue residue levels are not present.

     After  we  have received regulatory licensing or approval for our products,
numerous  regulatory requirements apply.  These include complying with the  Good
Manufacturing  Practice regulations, which require us  or  our  third  party  of
manufacturers  to  follow  elaborate testing, control, documentation  and  other
quality   assurance  procedures.   These  regulations  cover  the  manufacturing
process,  labeling  requirements,  the  general  prohibition  against  promoting
products for unapproved or "off-label" uses and reporting of adverse events.

     A  number of animal health products are not regulated.  For example, assays
for use in a veterinary diagnostic laboratory and various medical instruments do
not  have  to  be  licensed  by either the USDA or FDA.   Additionally,  various
botanically  derived  products, various nutritional products  and  grooming  and
supportive care products are exempt from significant regulation as long as  they
do not bear a therapeutic claim that represents the product as a drug.

     For  marketing  outside the United States, we are also subject  to  foreign
regulatory requirements governing regulatory licensing and approval for many  of
our  products.   The requirements governing product licensing and approval  vary
widely from country to country.  Licensing and approval by comparable regulatory
authorities  of  foreign countries must be obtained before  marketing  of  those
products  in  those  countries.  The approval process  varies  from  country  to
country  and the time required for such approvals may differ substantially  from
that  required in the United States.  We cannot be certain that approval of  any
of our products in one country will result in approvals in any other country.

COMPETITION

     The  market  in which we compete is intensely competitive.  Our competitors
include  independent animal health companies and major pharmaceutical  companies
that have animal health divisions.  Companies with a significant presence in the
companion  animal  health market, such as American Home Products,  Bayer,  IDEXX
Laboratories,  Inc., Intervet International B.V., Merial Ltd., Novartis,  Pfizer
Inc., Pharmacia Animal Health and Schering-Plough Corporation have developed or
are developing  products  that  do  or  would  compete  with  our  products.
These competitors  may have substantially greater financial, technical, research
and other resources and larger, more established marketing, sales, distribution
and service  organizations than us. Moreover, such competitors may offer broader
product  lines  and  have greater name recognition than  us.   Novartis  is  our
marketing  partner and its agreement with us does not restrict  its  ability  to
develop  and market competing products.  In addition, IDEXX, which has  products
that  compete with our heartworm diagnostic products, prohibits its distributors
from  selling competitiors' products, including ours.  The market for  companion
animal  health  care  products is highly fragmented, with  discount  stores  and
specialty pet stores accounting for a substantial percentage of such sales.   As
we  currently  distribute  our  products  primarily  through  veterinarians,   a
substantial segment of the potential market may not be reached and we may not be
able  to  offer  our  products at prices which are  competitive  with  those  of
companies that distribute their products through retail channels.

     The  food animal vaccines sold by Diamond to AgriLabs compete with  similar
products   offered  by  a  number  of  other  companies,  some  of  which   have
substantially  greater financial, technical, research and other  resources  than
Diamond   and  more  established  marketing,  sales,  distribution  and  service
organizations than AgriLabs.

EMPLOYEES

     As  of  December 31, 2000, we and our subsidiaries employed  336  full-time
persons,  of  whom  107  were in manufacturing, quality  control,  shipping  and
receiving,   and  materials  management,  90  were  in  research,   development,
intellectual  property and regulatory affairs, 57 were in  management,  finance,
administration,  legal,  information systems,  human  resources  and  facilities
management, 67 were in sales, marketing and customer service and 15 were in  the
diagnostic  laboratories.   None of our employees is  covered  by  a  collective
bargaining agreement, and we believe our employee relations are good.

ITEM 2.  PROPERTIES.

     We  currently  lease an aggregate of approximately 64,000  square  feet  of
administrative and laboratory space in four buildings located in  Fort  Collins,
Colorado under leases expiring through 2005, with options to extend through 2010
for  the larger facilities.  We believe that our present Fort Collins facilities
are adequate for our current and planned activities and that suitable additional
or  replacement  facilities in the Fort Collins area are  readily  available  on
commercially  reasonable terms should such facilities be needed in  the  future.
Diamond's  principal manufacturing facility in Des Moines, Iowa,  consisting  of
166,000  square  feet  of buildings on 34 acres of land, is  owned  by  Diamond.
Diamond also owns a 160-acre farm used principally for research purposes located
in  Carlisle, Iowa.  Our European subsidiaries lease their facilities.  We  also
currently  lease  approximately 19,500 square feet of office  and  manufacturing
space in Waukesha, Wisconsin which we have vacated and are currently seeking  to
sublease.

ITEM 3.  LEGAL PROCEEDINGS.

     In  November 1998, Synbiotics Corporation filed a lawsuit against us in the
United States District Court for the Southern District of California in which it
alleges  that  we  infringe a patent owned by Synbiotics relating  to  heartworm
diagnostic  technology.   No trial date has been set.  We  have  obtained  legal
opinions  from our outside patent counsel that our heartworm diagnostic products
do  not  infringe  the Synbiotics patent and that the patent  is  invalid.   The
opinions  of  non-infringement are consistent with the results of  our  internal
evaluations  related to the one remaining claim.  In September  2000,  the  U.S.
District  Court  hearing  the case granted our request  for  a  partial  summary
judgment,  holding  two of the Synbiotics patent claims to be  invalid,  leaving
only one remaining claim.

     While we believe that we have valid defenses to Synbiotics' allegations and
intend  to  defend  the  action vigorously, there can be no  assurance  that  an
adverse  result or settlement would not have a material adverse  effect  on  our
financial position, results of operations or cash flow.

ITEM 4.  SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS.

ITEM 7.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
 OF OPERATIONS.

     The  following  discussion  and analysis of  our  financial  condition  and
results  of operations should be read in conjunction with "Selected Consolidated
Financial  Data"  and the Consolidated Financial Statements  and  related  Notes
included in Items 6 and 8 of this Form 10-K.

     This discussion contains forward-looking statements that involve risks  and
uncertainties.   Such  statements, which include  statements  concerning  future
revenue  sources  and  concentration, gross  margins,  research and  development
expenses,  selling and marketing expenses, general and administrative  expenses,
capital  resources,  additional financings or borrowings and additional  losses,
are  subject  to  risks and uncertainties, including, but not limited  to, those
discussed  below and elsewhere in this Form 10-K, particulary in  "Factors  that
May  Affect Results," that could cause actual results to differ materially  from
those projected.

OVERVIEW

     We  discover,  develop,  manufacture and  market  companion  animal  health
products.   We  have  a  sophisticated scientific  effort  devoted  to  applying
biotechnology to create a broad range of pharmaceutical, vaccine and  diagnostic
products  for the large and growing companion animal health market.  In addition
to  our pharmaceutical, vaccine and diagnostic products, we also sell veterinary
diagnostic  and patient monitoring instruments and offer diagnostic services  in
the  United  States  and  Europe  to veterinarians.  Our  primary  manufacturing
subsidiary,  Diamond Animal Health, Inc., or Diamond, manufactures some  of  our
companion  animal  products and food animal vaccine and pharmaceutical  products
which are marketed and distributed by third parties.

     From  our  inception  in  1988 until early 1996, our  operating  activities
related  primarily  to  research  and  development  activities,  entering   into
collaborative  agreements, raising capital and recruiting personnel.   Prior  to
1996,  we had not received any revenues from the sale of products. During  1996,
we  grew  from being primarily a research and development concern  to  a  fully-
integrated  research,  development, manufacturing  and  marketing  company.   We
accomplished this by acquiring Diamond, a licensed pharmaceutical and biological
manufacturing  facility in Des Moines, Iowa, hiring key  employees  and  support
staff,  establishing  marketing and sales operations  to  support  our  products
introduced in 1996, and designing and implementing more sophisticated  operating
and information systems.  We also expanded the scope and level of our scientific
and  business  development  activities, increasing  the  opportunities  for  new
products.   In  1997, we introduced 13 additional products and expanded  in  the
United  States  through  the acquisition of Center, an  FDA  and  USDA  licensed
manufacturer  of  allergy  immunotherapy  products  located  in  New  York,  and
internationally  through the acquisitions of Heska UK, a  veterinary  diagnostic
laboratory  in  England and CMG in Switzerland, which manufactures  and  markets
allergy  diagnostic products for use in veterinary and human medicine, primarily
in  Europe.  Each of our acquisitions during this period was accounted for under
the  purchase  method  of accounting and accordingly, our  financial  statements
reflect  the  operations of these businesses only for the periods subsequent  to
the  acquisitions.   In  July 1997, we established a new subsidiary,  Heska  AG,
located  near  Basel,  Switzerland, for the purpose  of  managing  our  European
operations.

     During the first quarter of 1998 we acquired a manufacturer and marketer of
patient  monitoring  devices.  The financial results of this  entity  have  been
consolidated with ours under the pooling-of-interests accounting method for  all
periods  presented.   These  operations  were  consolidated  with  our  existing
operations  in  Fort Collins, Colorado and Des Moines, Iowa as of  December  31,
1999, and our facility in Waukesha, Wisconsin was closed.

     We  sold our subsidiary in the United Kingdom, Heska UK, in March 2000.  In
June 2000, we completed the sale of Center.

     We have incurred net losses since our inception and anticipate that we will
continue  to  incur additional net losses in the near term as we  introduce  new
products, expand our sales and marketing capabilities and continue our  research
and  development  activities.   Cumulative net losses  from  inception  in  1988
through December 31, 2000 have totaled $174.5 million.

     Our ability to achieve profitable operations will depend primarily upon our
ability  to  successfully market our existing products,  commercialize  products
that  are  currently under development and develop new products.   Most  of  our
products are subject to long development and regulatory approval cycles, and  we
may not successfully develop, manufacture or market these products.  We also may
not  attain  profitability  or, if achieved, may  not  remain  profitable  on  a
quarterly or annual basis in the future.  Until we attain positive cash flow, we
may  continue  to finance operations with additional equity and debt  financing.
Such  financing may not be available when required or may not be obtained  under
favorable terms.  See the discussion later in this section titled "Factors  That
May Affect Results" for a more in-depth explanation of risks faced by us.

RESULTS OF OPERATIONS

Years Ended December 31, 2000 and 1999

     Total  revenues,  which  include product revenues, sponsored  research  and
development  and other revenues, increased 3% to $52.7 million in 2000  compared
to $51.2 million in 1999. The total reported revenue included approximately $3.2
million in 2000 and $13.4 million in 1999 from businesses sold and non-strategic
product  lines  discontinued  during 2000.  Sales  to  one  customer,  AgriLabs,
represented 17% of total revenues in 2000.

     Product  revenues decreased 2% to $49.5 million in 2000 compared  to  $50.3
million in 1999. For the year ended December 31, 2000, product revenue from  our
continuing  core business increased 26%. This continuing core business  consists
of  the  following business components: pharmaceutical, vaccine  and  diagnostic
(PVD) products, veterinary monitoring and diagnostic instrumentation and Diamond
Animal  Health,  our  manufacturing subsidiary. The  fiscal  2000  increase  was
attributable to strong growth in our veterinary medical instrument products  and
to  increases  in  our  proprietary pharmaceuticals, vaccines  and  diagnostics.
Diamond also posted solid revenue growth during the year.

     Revenues  from  sponsored research and development and other  increased  to
$3.1  million in 2000 from $900,000 in 1999.  Included in the total for 2000  is
revenue  from  the sale of our worldwide rights to the PERIOceutic Gel  product.
Revenues from sponsored research and development increased due to an increase in
the number of funded research projects.

     Cost  of goods sold totaled $33.3 million in 2000 compared to $36.4 million
in 1999, and the resulting gross profit from product sales for 2000 increased to
$16.3 million from $13.9 million in 1999.
Our  gross  margin percentage was 33% in 2000, compared to 28% in 1999.   During
2000,  our gross margin improved as our product mix included a higher percentage
of  proprietary products with higher gross margins.  Also during fiscal 2000 and
late  in  fiscal 1999, we sold businesses and eliminated various  product  lines
that did not meet gross profit expectations.

     Selling  and marketing expenses remained relatively flat with $14.8 million
in  2000  as  compared  to $15.1 million in 1999, due to  the  sale  of  certain
businesses  offset  by the introduction and marketing costs  for  new  products.
Selling  and  marketing expenses consist primarily of salaries, commissions  and
benefits  for sales and marketing personnel, commissions paid to contract  sales
personnel and expenses of product advertising and promotion.  We expect  selling
and  marketing expenses to increase as sales volumes increase and  new  products
are  introduced  to  the marketplace, but to decrease as a percentage  of  total
revenues in future years.

     Research  and development expenses decreased to $14.9 million in 2000  from
$17.0  million  in 1999.  The decrease is due to additional focus  on  companion
animal  product opportunities and tight cost control.  Research and  development
expenses  are expected to decrease as a percentage of total revenues  in  future
years.

     General and administrative expenses decreased to $9.5 million in 2000  from
$11.2  million  in  1999.  The decrease in 2000 is due to the  sale  of  certain
businesses and tight cost control at all operations.  General and administrative
expenses  are expected to decrease as a percentage of total revenues  in  future
years.

     Amortization  of intangible assets and deferred compensation  decreased  to
$903,000  in  2000 from $2.2 million in 1999.  The amortization  of  intangibles
resulted in a non-cash charge to operations of $255,000 and $1.6 million in 2000
and  1999,  respectively.  The decrease is due to the sale of Heska UK  and  the
write-down  of certain intangible assets in 1999.  The amortization of  deferred
compensation  resulted  in  a  non-cash  charge  to  operations   in   2000   of
approximately $648,000 compared to $629,000 in 1999.  The deferred  compensation
represents  the  difference  between the exercise price  of  options  issued  to
employees  during  1996 and 1997 and the deemed value of the  common  stock  for
accounting purposes on the date of grant.  Compensation costs, equal to the fair
value  of  the  options on the date of grant, were recognized over  the  service
period.   The deferred compensation has been fully amortized as of December  31,
2000.

     The  loss  on  sale of assets in 2000 reflects the write-down to  net  book
value  of certain assets held for sale, offset by the gain on the sale of Center
of approximately $151,000.

     During  the  first  quarter of 2000, we recorded a  $435,000  restructuring
charge  related  to the rationalization of our business operations  at  Diamond.
Diamond  reduced  the  size  of  its  workforce  and  vacated  a  warehouse  and
distribution   facility  no  longer  needed  when  we  decided   to   discontine
manufacturing of certain low margin human healthcare products.

     Interest income decreased to just under $1.0 million in 2000 as compared to
$1.6 million in 1999 as we continued to fund our operations with available cash.
Interest income is expected to decrease in the future as we continue to use cash
to  fund our business operations.  Interest expense decreased to $1.2 million in
2000  from  $1.9  million in 1999 as we reduced our debt and capital  leases  by
nearly  $8.5  million during the year.  Other expense decreased to  $400,000  in
2000 from nearly $1.0 million in 1999 due primarily to lower losses realized  on
the  sale of certain long-term interest-bearing government securities during the
current year.

Years Ended December 31, 1999 and 1998

     Total  revenues,  which  include product revenues, sponsored  research  and
development and other revenues, increased 29% to $51.2 million in 1999  compared
to  $39.8  million in 1998.  Product revenues increased 31% to $50.3 million  in
1999 compared to $38.5 million in 1998.  The growth in revenues during 1999  was
primarily  due  to  sales of new products introduced during 1999  and  increased
sales  of our existing products.  Sales to one customer, Bayer, represented  12%
of  total  revenues in 1999 pursuant to a take-or-pay contract with  Bayer  that
expired  in  February  2000.  A portion of these sales  were replaced  under  an
agreement with AgriLabs.

     Revenues  from  sponsored research and development and other  decreased  to
$900,000  in  1999  from $1.3 million in 1998.  Fluctuations  in  revenues  from
sponsored  research and development are generally the result of changes  in  the
number of funded research projects.

     Cost  of goods sold totaled $36.4 million in 1999 compared to $29.1 million
in 1998, and the resulting gross profit from product sales for 1999 increased to
$13.9 million from $9.4 million in 1998.  Our gross margin percentage was 28% in
1999, compared to 24% in 1998.  During 1999, the gross profit margin improved as
our product mix included a higher percentage of proprietary products with higher
gross  profit  margins.  Also during fiscal 1999, we eliminated various  product
lines that did not meet gross profit expectations.

     Research  and development expenses decreased to $17.0 million in 1999  from
$25.1 million in 1998.  The decrease in 1999 was primarily due to reductions  in
our   internal   research  and  development  activities,  resulting   from   our
restructuring in December 1998, and our decision to eliminate or defer  research
projects  which  appeared  to  have  greater  long-term  risk  or  lower  market
potential.

     Selling  and  marketing expenses increased to $15.1 million  in  1999  from
$13.2  million in 1998.  This increase reflects primarily the expansion  of  our
sales and marketing organization and costs associated with the introduction  and
marketing of new products.

     General and administrative expenses decreased to $11.2 million in 1999 from
$11.9 million in 1998.  The decrease in 1999 was primarily due to reductions  in
staffing and expenditures, resulting from our restructuring in December 1998.

     Amortization  of intangible assets and deferred compensation  decreased  to
$2.2  million  in  1999 from $2.7 million in 1998.  Intangible  assets  resulted
primarily  from our 1997 and 1996 business acquisitions and are being  amortized
over lives of 2 to 10 years.  The amortization of deferred compensation resulted
in a non-cash charge to operations in 1999 of approximately $629,000 compared to
$736,000 in 1998.

     The  loss on assets held for disposition of $2.6 million recorded  in  1999
reflects  the  write-down  of certain tangible and intangible  assets  to  their
expected  net realizable values.  Included in the loss was $1.0 million  related
to  the  sale of Heska UK, a write-off of $580,000 in book value of assets  held
for  sale  resulting from our decision to discontinue contract manufacturing  of
certain low margin human healthcare products for third parties at Diamond and  a
write-off  of  $1.0  million in book value of certain  intangible  and  tangible
assets no longer considered strategic and held for sale or other disposition.

     During  the third quarter of 1999, we recognized a charge to operations  of
approximately $1.2 million related to our decision to consolidate the operations
of  our  Waukesha,  Wisconsin  facility into our  existing  operations  in  Fort
Collins,  Colorado and Des Moines, Iowa.  The charge was primarily for personnel
severance costs and the cost of closing the facility in Waukesha, Wisconsin.

     Interest income decreased to $1.6 million in 1999 from $3.2 million in 1998
as  a  result of reduced cash available for investment as we funded our business
operations.  Interest income is expected to decline in the future as we continue
to  use  cash  to  fund  our  business operations.  Interest  expense  decreased
slightly  to $1.9 million in 1999 from $2.0 million in 1998.  Other  expense  of
nearly $1.0 million in 1999 is due primarily to the loss realized on the sale of
certain long-term, interest-bearing government securities.

LIQUIDITY AND CAPITAL RESOURCES

     Our  primary source of liquidity at December 31, 2000 was $5.7  million  in
cash,  cash equivalents and marketable securities and our asset-based  revolving
line of credit.  In June 2000, we entered into the two-year credit facility with
Wells  Fargo  Business Credit, an affiliate of Wells Fargo  Bank.   This  credit
facility  requires us to maintain various minimum financial covenants  including
book  net  worth,  net income and cash balances or liquidity levels.   In  March
2001, we negotiated new covenants under this line of credit.  At March 27, 2001,
our  available borrowing capacity was approximately $5.0 million.   In  February
2001,  we  sold 4,573,000 shares of our common stock through a private placement
offering and received net proceeds of $5.3 million.

     Net  cash  used in operating activities was $15.9 million in 2000, compared
to  $33.2 million in 1999.  Accounts payable decreased by $2.6 million  in  2000
primarily due to the lower inventory levels.  Inventory levels decreased by $2.4
million in 2000, due to a program to reduce inventory levels at Diamond.

     Net  cash  flows from investing activities provided us with  $25.2  million
during  2000,  compared to $20.3 million of cash provided  in  1999.   The  cash
provided in 2000 resulted primarily from the sale of $20.0 million of marketable
securities and the sale of Center for approximately $6.0 million.  It  was  used
to  fund  our  current  year operations and debt repayments.   Expenditures  for
property and equipment totaled $1.2 million for 2000 compared to $3.3 million in
1999.   We have historically used, and anticipate that we will continue to  use,
capital equipment lease and debt facilities to finance equipment purchases  and,
if possible, leasehold improvements.  We currently expect to spend approximately
$1.5  million in 2001 for capital equipment, including expenditures  to  upgrade
certain  manufacturing operations to improve efficiencies and to assure  ongoing
compliance   with   regulatory  requirements.   We  expect  to   finance   these
expenditures   through  available  cash,  equipment  leases  and  secured   debt
facilities.

     Net cash flows from financing activities used $7.6 million in cash in 2000,
compared  to generating $8.4 million in 1999.  Our primary use of cash  in  2000
was  the  repayment of debt and capital lease obligations totaling  nearly  $8.5
million.   The primary source of cash in 1999 was the public offering of  common
stock  in  December  which provided us with net proceeds of approximately  $13.3
million.   We  also  borrowed an additional $971,000 under our available  credit
facilities.   We  used  cash to repay $6.5 million of  debt  and  capital  lease
obligations.

     Our  primary short-term needs for capital, which are subject to change, are
for  our  continuing research and development efforts, our sales, marketing  and
administrative  activities, working capital associated  with  increased  product
sales  and  capital  expenditures  relating  to  developing  and  expanding  our
manufacturing  operations.  Our future liquidity and capital  requirements  will
depend on numerous factors, including the extent to which our present and future
products  gain  market acceptance, the extent to which products or  technologies
under  research  or  development  are  successfully  developed,  the  timing  of
regulatory actions regarding our products, the costs and timing of expansion  of
sales, marketing and manufacturing activities, the cost, timing   and  business
management of current  and  potential  acquisitions and   contingent liabilities
associated  with such  acquisitions, the procurement and enforcement of patents
important to  our business and the results of competition.

     We  believe  that  our  available  cash, cash  equivalents  and  marketable
securities,  together  with  cash  from  operations,  available  borrowings  and
borrowings we expect to be available under our revolving line of credit facility
will  be  sufficient  to  satisfy our projected  cash  requirements  into  2002,
although we may raise additional funds at or before such time.  If necessary, we
expect  to  raise these additional funds through one or more of  the  following:
(1) sale of additional securities; (2) sale of various assets; (3) licensing  of
technology; and (4) sale of various products or marketing rights.  If we  cannot
raise the additional funds through these options on acceptable terms or with the
necessary  timing,  management  could  also  reduce  discretionary  spending  to
decrease  our  cash  burn  rate and extend the currently  available  cash,  cash
equivalents, marketable securities and available borrowings.  See "Factors  that
May Affect Results."

     On  February  6, 2001, we sold 4,573,000 shares of common stock  through  a
private  placement  offering  and received net proceeds  of  approximately  $5.3
million.

NET OPERATING LOSS CARRYFORWARDS

     As  of December 31, 2000, we had a net operating loss carryforward, or NOL,
of  approximately $154.6 million and approximately $3.1 million of research  and
development  tax credits available to offset future federal income  taxes.   The
NOL  and tax credit carryforwards, which are subject to alternative minimum  tax
limitations and to examination by the tax authorities, expire from 2003 to 2020.
Our  acquisition  of  Diamond  resulted in a "change  of  ownership"  under  the
provisions of Section 382 of the Internal Revenue Code of 1986, as amended.   As
such,  we  will be limited in the amount of NOL's incurred prior to  the  merger
that we may utilize to offset future taxable income.  This limitation will total
approximately  $4.7  million  per year for periods  subsequent  to  the  Diamond
acquisition.   Similar  limitations also apply to utilization  of  research  and
development tax credits to offset taxes payable. We believe that this limitation
may affect the eventual utilization of our total NOL carryforwards.

RECENT ACCOUNTING PRONOUNCEMENTS

     In  December  1999,  the  Securities and Exchange Commission  issued  Staff
Accounting  Bulletin No. 101, Revenue Recognition.  SAB 101  clarifies  the  SEC
staff's  views in applying generally accepted accounting principles to  selected
revenue  recognition  issues.   We adopted SAB  101  during  the  quarter  ended
December  31, 2000.  The adoption of SAB 101 did not have a material  impact  on
our  financial statements, and therefore, did not result in the recording  of  a
cumulative  effect of change in accounting principles as if  SAB  101  had  been
adopted  on  January  1,  2000, or the restatement of  the  previously  reported
quarterly results for 2000.

     We do not expect the adoption of any other standards recently issued by the
Financial  Accounting Standards Board or the Securities and Exchange  Commission
to have a material impact on our financial position or results of operations.

FACTORS THAT MAY AFFECT RESULTS

We have a history of losses and may never achieve profitability.

     We have incurred net losses since our inception in 1988 and, as of December
31,  2000, we had an accumulated deficit of $174.5 million.  We anticipate  that
we  will continue to incur additional operating losses in the near term.   These
losses have resulted principally from expenses incurred in our research and
development programs and from general and administrative and sales and marketing
expenses.   Even if we achieve profitability, we may not be able to  sustain  or
increase profitability on a quarterly or annual basis.

We may need additional capital in the future.

     We  have  incurred  negative cash flow from operations since  inception  in
1988.   We  do not expect to generate positive cash flow sufficient to fund  our
operations in the near term.  Moreover, based on our current projections, we may
need  to  raise additional capital in the future.  If necessary,  we  expect  to
raise this additional capital through one or more of the following:




               

          *       sale of additional securities;
          *       sale of various assets;
          *       licensing of technology; and
          *       sale of various products or marketing
                  rights.


     Additional  capital may not be available on acceptable terms,  if  at  all.
Furthermore,  any  additional  equity financing  would  likely  be  dilutive  to
stockholders,  and  additional  debt  financing,  if  available,   may   include
restrictive  covenants  which  may limit our currently  planned  operations  and
strategies.  If adequate funds are not available, we may be required to  curtail
our  operations significantly and reduce discretionary spending  to  extend  the
currently  available  cash  resources, or  to  obtain  funds  by  entering  into
collaborative agreements or other arrangements on unfavorable terms.  If we fail
to  generate adequate funding on acceptable terms when we need to, our  business
could be substantially harmed.

We have limited resources to devote to product development and
commercialization.  If we are not able to devote resources to product
development and commercialization, we may not be able to develop our products.

     Our  strategy is to develop a broad range of products addressing  companion
animal  healthcare.   We believe that our revenue growth and  profitability,  if
any, will substantially depend upon our ability to:



               
          *       improve market acceptance of our current
                  products;
          *       complete development of new products; and
          *       successfully introduce and commercialize new
                  products.



     We  have  introduced some of our products only recently  and  many  of  our
products  are  still  under development. Because we have  limited  resources  to
devote   to  product  development  and  commercialization,  any  delay  in   the
development  of one product or reallocation of resources to product  development
efforts that prove unsuccessful may delay or jeopardize the development  of  our
other product candidates.  If we fail to develop new products and bring them  to
market, our ability to generate revenues will decrease.


     In  addition, our products may not achieve satisfactory market  acceptance,
and we may not successfully commercialize them on a timely basis, or at
all.   If  our products do not achieve a significant level of market acceptance,
demand for our products will not develop as expected and it is unlikely that  we
ever will become profitable.

We must obtain and maintain costly regulatory approvals in order to market our
products.

     Many  of  the  products  we  develop and market are  subject  to  extensive
regulation  by  one or more of the United States Department of  Agriculture,  or
USDA,  the  Food  and Drug Administration, or FDA, the Environmental  Protection
Agency,  or EPA, and foreign regulatory authorities.  These regulations  govern,
among  other things, the development, testing, manufacturing, labeling, storage,
premarket  approval,  advertising,  promotion,  sale  and  distribution  of  our
products.   Satisfaction of these requirements can take several years  and  time
needed to satisfy them may vary substantially, based on the type, complexity and
novelty of the product.  The effect of government regulation may be to delay  or
to  prevent marketing of our products for a considerable period of time  and  to
impose costly procedures upon our activities.  We have experienced in the  past,
and  may  experience in the future, difficulties that could delay or prevent  us
from  obtaining  the regulatory approval or license necessary  to  introduce  or
market  our  products.   Regulatory approval of our  products  may  also  impose
limitations  on  the indicated or intended uses for which our  products  may  be
marketed.

     Among  the conditions for regulatory approval is the requirement  that  our
manufacturing  facilities or those of our third party manufacturers  conform  to
current   Good   Manufacturing  Practices.   The  FDA  and  foreign   regulatory
authorities  strictly enforce Good Manufacturing Practices requirements  through
periodic inspections.  We can provide no assurance that any regulatory authority
will  determine  that our manufacturing facilities or those of our  third  party
manufacturers   will  conform  to  Good  Manufacturing  Practices  requirements.
Failure  to  comply  with  applicable  regulatory  requirements  can  result  in
sanctions  being  imposed on us or the manufacturers of our products,  including
warning  letters,  product recalls or seizures, injunctions, refusal  to  permit
products  to be imported into or exported out of the United States, refusals  of
regulatory authorities to grant approval or to allow us to enter into government
supply  contracts,  withdrawals of previously approved  marketing  applications,
civil fines and criminal prosecutions.

Factors  beyond  our control may cause our operating results to  fluctuate,  and
since  many  of our expenses are fixed, this fluctuation could cause  our  stock
price to decline.

     We  believe that our future operating results will fluctuate on a quarterly
basis due to a variety of factors, including:




             

          *     the  introduction of new products by us or  by  our
                competitors;
          *     market acceptance of our current or new products;
          *     regulatory and other delays in product development;
          *     product recalls;
          *     competition  and pricing pressures from competitive
                products;
          *     manufacturing delays;
          *     shipment problems;
          *     product seasonality; and
          *     changes in the mix of products sold.


     We  have high operating expenses for personnel, new product development and
marketing.  Many of these expenses are fixed in the short term.  If any  of  the
factors listed above cause our revenues to decline, our operating results  could
be substantially harmed.

     Our  operating  results in some quarters may not meet the  expectations  of
stock  market  analysts and investors.  In that case, our stock  price  probably
would decline.

We  must maintain various financial and other covenants under our revolving line
of credit agreement.

     Under  our  revolving  line of credit agreement with Wells  Fargo  Business
Credit, Inc., we are required to comply with various financial and non-financial
covenants, and we have made various representations and warranties.   Among  the
financial covenants are requirements for monthly minimum book net worth, minimum
quarterly net income and minimum cash balances or liquidity levels.  Failure  to
comply with any of the covenants, representations or warranties would negatively
impact  our ability to borrow under the agreement.  Our inability to  borrow  to
fund our operations could materially harm our business.

A  small  number  of  large  customers account for a  large  percentage  of  our
revenues, and the loss of any of them could harm our operating results.

     We currently derive a substantial portion of our revenues from sales by our
subsidiary Diamond, which manufactures various of our products and products  for
other companies in the animal health industry.  Revenues from Diamond customers,
AgriLabs  and  Bayer, comprised approximately 17% and 12% of our total  revenues
for  the  years ended December 31, 2000 and 1999, respectively.  If we  are  not
successful in maintaining our relationships with our customers and obtaining new
customers, our business and results of operations will suffer.

We  operate  in a highly competitive industry, which could render  our  products
obsolete or substantially limit the volume of products that we sell.  This would
limit our ability to compete and achieve profitability.

     We   compete   with   independent  animal  health   companies   and   major
pharmaceutical  companies that have animal health divisions.  Companies  with  a
significant  presence  in  the  animal health  market,  such  as  American  Home
Products,  Bayer, IDEXX Laboratories, Inc., Intervet International B.V.,  Merial
Ltd.,  Novartis,  Pfizer  Inc.,  Pharmacia Animal  Health  and  Schering  Plough
Corporation,  have developed or are developing products that  compete  with  our
products  or would compete with them if developed.  These competitors  may  have
substantially  greater financial, technical, research and  other  resources  and
larger,   better-established   marketing,  sales,   distribution   and   service
organizations than us.  In addition, IDEXX, which has products that compete with
our  heartworm  diagnostic  products, prohibits its  distributors  from  selling
competitors' products, including ours.  Our competitors frequently offer broader
product lines and have greater name recognition than we do.  Our competitors may
develop  or  market  technologies  or  products  that  are  more  effective   or
commercially  attractive  than our current or future  products,  or  that  would
render  our technologies and products obsolete.  Further, additional competition
could come from new entrants to the animal healthcare market.  Moreover, we  may
not have the financial resources, technical expertise or marketing, distribution
or  support  capabilities  to  compete successfully.   If  we  fail  to  compete
successfully, our ability to achieve profitability will be limited.

We  have  limited  experience in marketing our products, and may  be  unable  to
commercialize our products.

     The  market  for companion animal healthcare products is highly fragmented,
with  discount  stores  and specialty pet stores accounting  for  a  substantial
percentage of sales.  Because we sell our companion animal health products  only
to  veterinarians, we may fail to reach a substantial segment of  the  potential
market,  and  we  may  not be able to offer our products  at  prices  which  are
competitive  with  those  of companies that distribute  their  products  through
retail  channels.  We currently market our products to veterinarians  through  a
direct sales force and through third parties.  To be successful, we will have to
continue  to  develop  and train our direct sales force  or  rely  on  marketing
partnerships or other arrangements with third parties to market, distribute  and
sell  our  products.   We may not successfully develop and  maintain  marketing,
distribution  or sales capabilities, and we may not be able to make arrangements
with  third  parties to perform these activities on satisfactory terms.   If  we
fail  to  develop a successful marketing strategy, our ability to  commercialize
our products and generate revenues will decrease.

We have granted third parties substantial marketing rights to our products under
development.   If  our  current  third  party  marketing  agreements   are   not
successful,  or  if we are unable to develop our own marketing  capabilities  or
enter into additional marketing agreements in the future, we may not be able  to
develop and commercialize our products.

     Our  agreements with our corporate marketing partners generally contain  no
minimum  purchase requirements in order for them to maintain their exclusive  or
co-exclusive marketing rights.  Novartis, Eisai or Ralston Purina or  any  other
collaborative  party  may  not  devote sufficient  resources  to  marketing  our
products.   Furthermore, there is nothing to prevent Novartis, Eisai or  Ralston
Purina  or  any other collaborative party from pursuing alternative technologies
or  products  that  may compete with our products.  If we fail  to  develop  and
maintain our own marketing capabilities, we may find it necessary to continue to
rely  on  potential or actual competitors for third party marketing  assistance.
Third  party  marketing  assistance  may not  be  available  in  the  future  on
reasonable terms, if at all.  If any of these events occur, we may not  be  able
to develop and commercialize our products and our revenues will decline.

We may face costly intellectual property disputes.

     Our  ability to compete effectively will depend in part on our  ability  to
develop and maintain proprietary aspects of our technology and either to operate
without  infringing  the proprietary rights of others or  to  obtain  rights  to
technology  owned  by third parties.  We have United States  and  foreign-issued
patents  and are currently prosecuting patent applications in the United  States
and  with  various foreign countries.  Our pending patent applications  may  not
result  in  the  issuance of any patents or that any issued patents  will  offer
protection against competitors with similar technology.  Patents we receive  may
be  challenged, invalidated or circumvented in the future or the rights  created
by those patents may not provide a competitive advantage.  We also rely on trade
secrets, technical know-how and continuing invention to develop and maintain our
competitive position.  Others may independently develop substantially equivalent
proprietary  information and techniques or otherwise gain access  to  our  trade
secrets.

     The biotechnology and pharmaceutical industries have been characterized  by
extensive litigation relating to patents and other intellectual property rights.
In 1998, Synbiotics Corporation filed a lawsuit against us alleging infringement
of  a  Synbiotics patent relating to heartworm diagnostic technology,  and  this
litigation  remains  ongoing.   We  may  become  subject  to  additional  patent
infringement  claims and litigation in the United States or other  countries  or
interference  proceedings conducted in the United States  Patent  and  Trademark
Office to determine the priority of inventions.  The defense and prosecution  of
intellectual  property suits, USPTO interference proceedings, and related  legal
and  administrative proceedings are costly, time-consuming and distracting.   We
may  also need to pursue litigation to enforce any patents issued to us  or  our
collaborative partners, to protect trade secrets or know-how owned by us or  our
collaborative partners, or to determine the enforceability, scope  and  validity
of  the proprietary rights of others.  Any litigation or interference proceeding
will  result  in  substantial  expense to us and significant  diversion  of  the
efforts of our technical and management personnel.  Any adverse determination in
litigation   or  interference  proceedings  could  subject  us  to   significant
liabilities  to  third  parties.  Further, as a result of  litigation  or  other
proceedings,  we may be required to seek licenses from third parties  which  may
not be available on commercially reasonable terms, if at all.

     We  license  technology from a number of third parties.   The  majority  of
these  license agreements impose due diligence or milestone obligations  on  us,
and  in  some cases impose minimum royalty and/or sales obligations  on  us,  in
order  for  us to maintain our rights under these agreements.  Our products  may
incorporate technologies that are the subject of patents issued to,  and  patent
applications filed by, others.  As is typical in our industry, from time to time
we  and  our collaborators have received, and may in the future receive, notices
from  third parties claiming infringement and invitations to take licenses under
third  party  patents.  It is our policy that when we receive such  notices,  we
conduct  investigations of the claims they assert.  With respect to the  notices
we  have  received to date, we believe, after due investigation,  that  we  have
meritorious  defenses  to the infringement claims asserted.   Any  legal  action
against  us or our collaborators may require us or our collaborators  to  obtain
one  or  more  licenses in order to market or manufacture affected  products  or
services.   However, we cannot assure you that we or our collaborators  will  be
able  to  obtain  licenses  for technology patented by  others  on  commercially
reasonable  terms,  that  we will be able to develop alternative  approaches  if
unable  to  obtain  licenses, or that the current and future  licenses  will  be
adequate  for  the  operation of our businesses.  Failure  to  obtain  necessary
licenses  or to identify and implement alternative approaches could  prevent  us
and  our  collaborators from commercializing our products under development  and
could substantially harm our business.

We  have limited manufacturing experience and capacity and rely substantially on
third  party  manufacturers.  The loss of any third  party  manufacturers  could
limit our ability to launch our products in a timely manner, or at all.

     To  be successful, we must manufacture, or contract for the manufacture of,
our  current and future products in compliance with regulatory requirements,  in
sufficient  quantities and on a timely basis, while maintaining product  quality
and  acceptable  manufacturing costs.  In order to  increase  our  manufacturing
capacity, we acquired Diamond in April 1996.

     We  currently rely on third parties to manufacture those products we do not
manufacture  at our Diamond facility.  We currently have supply agreements  with
Quidel  Corporation for various manufacturing services relating to our point-of-
care  diagnostic tests, with Centaq, Inc. for the manufacture of our own allergy
immunotherapy treatment products and with various manufacturers for  the  supply
of   our   veterinary  diagnostic  and  patient  monitoring  instruments.    Our
manufacturing strategy presents the following risks:




         

     *      Delays in the scale-up to quantities needed for product
            development could delay regulatory submissions and
            commercialization of our products in development;

     *      Our manufacturing facilities and those of some of our third
            party manufacturers are subject to ongoing periodic
            unannounced inspection by regulatory authorities, including
            the FDA, USDA and other federal and state agency's for
            compliance with strictly enforced Good Manufacturing
            Practices regulations and similar foreign standards, and we
            do not have control over our third party manufacturers'
            compliance with these regulations and standards;

     *      If we need to change to other commercial manufacturing
            contractors for certain of our products, additional
            regulatory licenses or approvals must be obtained for these
            contractors prior to our use.  This would require new
            testing and compliance inspections.  Any new manufacturer
            would have to be educated in, or develop substantially
            equivalent processes necessary for the production of our
            products;

     *      If market demand for our products increases suddenly, our
            current manufacturers might not be able to fulfill our
            commercial needs, which would require us to seek new
            manufacturing arrangements and may result in substantial
            delays in meeting market demand; and

     *      We may not have intellectual property rights, or may have to
            share intellectual property rights, to any improvements in
            the manufacturing processes or new manufacturing processes
            for our products.



     Any  of  these factors could delay commercialization of our products  under
development, interfere with current sales, entail higher costs and result in our
being unable to effectively sell our products.

     Our agreements with various suppliers of the veterinary medical instruments
require us to meet minimum annual sales levels to maintain our position  as  the
exclusive distributor of these instruments.  We may not meet these minimum sales
levels in the future, and maintain exclusivity over the distribution and sale of
these  products.   If  we are not the exclusive distributor of  these  products,
competition may increase.

We  depend  on  partners  in our research and development  activities.   If  our
current  partnerships and collaborations are not successful, we may not be  able
to develop our technologies or products.

     For  various  of  our proposed products, we are dependent on  collaborative
partners  to successfully and timely perform research and development activities
on  our  behalf.   These  collaborative partners may not complete  research  and
development  activities on our behalf in a timely fashion, or at  all.   If  our
collaborative partners fail to complete research and development activities,  or
fail  to  complete them in a timely fashion, our ability to develop technologies
and products will be impacted negatively and our revenues will decline.

We depend on key personnel for our future success.  If we lose our key personnel
or  are  unable to attract and retain additional personnel, we may be unable  to
achieve our goals.

     Our  future success is substantially dependent on the efforts of our senior
management  and  scientific team.  The loss of the services of  members  of  our
senior management or scientific staff may
significantly delay or prevent the achievement of product development and  other
business  objectives.   Because  of the specialized  scientific  nature  of  our
business, we depend substantially on our ability to attract and retain qualified
scientific  and technical personnel.  There is intense competition  among  major
pharmaceutical  and  chemical  companies, specialized  biotechnology  firms  and
universities  and  other research institutions for qualified  personnel  in  the
areas  of  our activities.  If we lose the services of, or fail to recruit,  key
scientific  and  technical  personnel, the  growth  of  our  business  could  be
substantially impaired.

We  may face product returns and product liability litigation and the extent  of
our  insurance  coverage is limited.  If we become subject to product  liability
claims  resulting  from defects in our products, we may fail to  achieve  market
acceptance of our products and our business could be harmed.

     The testing, manufacturing and marketing of our current products as well as
those  currently under development entail an inherent risk of product  liability
claims  and  associated  adverse publicity.  Following  the  introduction  of  a
product,  adverse  side effects may be discovered.  Adverse publicity  regarding
such  effects could affect sales of our other products for an indeterminate time
period.  To date, we have not experienced any material product liability claims,
but  any  claim  arising in the future could substantially  harm  our  business.
Potential  product  liability  claims may exceed the  amount  of  our  insurance
coverage or may be excluded from coverage under the terms of the policy.  We may
not be able to continue to obtain adequate insurance at a reasonable cost, if at
all.  In the event that we are held liable for a claim against which we are  not
indemnified  or  for damages exceeding the $10 million limit  of  our  insurance
coverage  or which results in significant adverse publicity against us,  we  may
lose revenue and fail to achieve market acceptance.

We may be held liable for the release of hazardous materials, which could result
in extensive costs which would harm our business.

     Our  products  and  development  programs involve  the  controlled  use  of
hazardous  and  biohazardous materials, including chemicals, infectious  disease
agents  and various radioactive compounds.  Although we believe that our  safety
procedures  for  handling  and  disposing of  such  materials  comply  with  the
standards  prescribed  by  applicable local, state and federal  regulations,  we
cannot completely eliminate the risk of accidental contamination or injury  from
these materials.  In the event of such an accident, we could be held liable  for
any  fines,  penalties,  remediation costs or other damages  that  result.   Our
liability  for  the release of hazardous materials could exceed  our  resources,
which  could lead to a shut down of our operations.  In addition, we  may  incur
substantial  costs to comply with environmental regulations  as  we  expand  our
manufacturing capacity.

We  expect  to  experience volatility in our stock price, which may  affect  our
ability  to  raise capital in the future or make it difficult for  investors  to
sell their shares.

     The securities markets have from time to time experienced significant price
and  volume  fluctuations  that are unrelated to the  operating  performance  of
particular  companies.   The market prices of securities of  many  publicly-held
biotechnology companies have in the past been, and can in the future be expected
to  be, especially volatile.  For example, in the last twelve months our closing
stock  price has ranged from a low of $0.59375 to a high of $4.50.  Fluctuations
in  the trading price or liquidity of our common stock may adversely affect  our
ability  to  raise capital through future equity financings.  Factors  that  may
have  a  significant impact on the market price and marketability of our  common
stock include:



          

     *       announcements of technological innovations or new products by us or by
             our competitors;
     *       our quarterly operating results;
     *       releases of reports by securities analysts;
     *       developments or disputes concerning patents or proprietary rights;
     *       regulatory developments;
     *       developments in our relationships with collaborative partners;
     *       changes in regulatory policies;
     *       litigation;
     *       economic and other external factors; and
     *       general market conditions.



In  the past, following periods of volatility in the market price of a company's
securities, securities class action litigation has often been instituted.  If  a
securities  class  action suit is filed against us, we would  incur  substantial
legal  fees and our management's attention and resources would be diverted  from
operating our business in order to respond to the litigation.

If we fail to meet Nasdaq National Market listing requirements, our common stock
will be delisted and become illiquid.

     Our common stock is currently listed on the Nasdaq National Market.  Nasdaq
has  requirements we must meet in order to remain listed on the Nasdaq  National
Market.   If  we  continue to experience losses from our operations  or  we  are
unable to raise additional funds, we might not be able to maintain the standards
for  continued quotation on the Nasdaq National Market, including a minimum  bid
price  requirement of $1.00.  If the minimum bid price of our common stock  were
to  remain below $1.00 for 30 consecutive trading days, or if we were unable  to
continue to meet Nasdaq's standards for any other reason, our common stock could
be delisted from the Nasdaq National Market.

     If as a result of the application of these listing requirements, our common
stock  were  delisted from the Nasdaq National Market, our  stock  would  become
harder  to buy and sell.  Further, our stock could be subject to what are  known
as the "penny stock" rules.  The penny stock rules place additional requirements
on  broker-dealers who sell or make a market in such securities.   Consequently,
if  we  were removed from the Nasdaq National Market, the ability or willingness
of  broker-dealers to sell or make a market in our common stock  might  decline.
As  a  result,  the ability for investors to resell shares of our  common  stock
could be adversely affected.

ITEM 7A.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.

     Market  risk  represents  the risk of loss that may  impact  the  financial
position,  results  of  operations  or cash flows  due  to  adverse  changes  in
financial and commodity market prices and rates.  We are exposed to market  risk
in  the areas of changes in United States and foreign interest rates and changes
in foreign currency exchange rates as measured against the United States dollar.
These  exposures  are  directly  related to our  normal  operating  and  funding
activities.   Historically,  and as of December  31,  2000,  we  have  not  used
derivative instruments or engaged in hedging activities.

Interest Rate Risk

     The interest payable on certain of our lines of credit and other borrowings
is  variable  based on the United States prime rate, or LIBOR,  and,  therefore,
affected   by  changes  in  market  interest  rates.   At  December  31,   2000,
approximately  $2.9 million was outstanding on these lines of credit  and  other
borrowings with a weighted average interest rate of 10.75%.  We manage  interest
rate  risk  by  investing  excess  funds  principally  in  cash  equivalents  or
marketable  securities  which bear interest rates that  reflect  current  market
yields.   Additionally, we monitor interest rates and at December 31,  2000  had
sufficient  cash balances to pay off the lines-of-credit should  interest  rates
increase       significantly.        As       a       result,       we        do
not  believe  that  reasonably  possible near-term  changes  in  interest  rates
will  result in a material effect on our future earnings, financial position  or
cash flows.

Foreign Currency Risk

     At  December  31,  2000,  we  had  a  wholly-owned  subsidiary  located  in
Switzerland.   Sales from these operations are denominated in  Swiss  Francs  or
Euros, thereby creating exposures to changes in exchange rates.  The changes  in
the  Swiss/U.S.  exchange  rate or Euro/U.S. exchange  rate  may  positively  or
negatively  affect our sales, gross margins and retained earnings.   We  do  not
believe that reasonably possible near-term changes in exchange rates will result
in  a  material  effect  on  future earnings, fair values  or  cash  flows,  and
therefore,  have chosen not to enter into foreign currency hedging  instruments.
Such an approach may not be successful, especially in the event of a significant
and sudden decline in the value of the Swiss Franc or Euro.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS



To Heska Corporation:

     We  have  audited  the accompanying consolidated balance  sheets  of  Heska
Corporation  (a Delaware corporation) and subsidiaries as of December  31,  2000
and   1999,   and   the  related  consolidated  statements  of  operations   and
comprehensive loss, stockholders' equity and cash flows for each  of  the  three
years in the period ended December 31, 2000.  These financial statements are the
responsibility of the Company's management.  Our responsibility is to express an
opinion on these financial statements based on our audits.

     We  conducted  our  audits in accordance with auditing standards  generally
accepted in the United States.  Those standards require that we plan and perform
the  audit to obtain reasonable assurance about whether the financial statements
are  free  of  material misstatement.  An audit includes examining,  on  a  test
basis,  evidence  supporting  the  amounts  and  disclosures  in  the  financial
statements.  An audit also includes assessing the accounting principles used and
significant  estimates  made by management, as well as  evaluating  the  overall
financial  statement  presentation.   We  believe  that  our  audits  provide  a
reasonable basis for our opinion.

     In  our opinion, the financial statements referred to above present fairly,
in  all  material  respects, the financial position  of  Heska  Corporation  and
subsidiaries  as  of  December  31, 2000 and 1999,  and  the  results  of  their
operations and their cash flows for each of the three years in the period  ended
December  31, 2000, in conformity with accounting principles generally  accepted
in the United States.

     Our  audit  was  made for the purpose of forming an opinion  on  the  basic
financial statements taken as a whole.  The schedule of valuation and qualifying
accounts is presented for purposes of complying with the Securities and Exchange
Commission's  rules  and  is not part of the basic financial  statements.   This
schedule  has been subjected to the auditing procedures applied in the audit  of
the  basic  financial  statements and, in our  opinion,  fairly  states  in  all
material  respects  the  financial data required to  be  set  forth  therein  in
relation to the basic financial statements taken as a whole.

1.   ORGANIZATION AND BUSINESS

     Heska  Corporation ("Heska" or the "Company") is primarily focused  on  the
discovery,  development, manufacturing and marketing of companion animal  health
products.   In  addition  to manufacturing certain of Heska's  companion  animal
health  products, the Company's primary manufacturing subsidiary, Diamond Animal
Health,  Inc.  ("Diamond"), manufactures food animal vaccine and  pharmaceutical
products  that are marketed and distributed by third parties.  The Company  also
offers  diagnostic services to veterinarians at its Fort Collins,  Colorado  and
CMG-Heska Allergy Products S.A. ("CMG"), a Swiss corporation, locations.

     From  the  Company's  inception in 1988 until  early  1996,  the  Company's
operating  activities related primarily to research and development  activities,
entering   into   collaborative  agreements,  raising  capital  and   recruiting
personnel.   Prior to 1996, the Company had not received any revenues  from  the
sale  of products.  During 1996, Heska grew from being primarily a research  and
development  concern to a fully-integrated research, development,  manufacturing
and  marketing company.  The Company accomplished this by acquiring  Diamond,  a
licensed  pharmaceutical and biological manufacturing facility  in  Des  Moines,
Iowa,  hiring key employees and support staff, establishing marketing and  sales
operations  to  support new Heska products, and designing and implementing  more
sophisticated operating and information systems.  The Company also expanded  the
scope   and  level  of  its  scientific  and  business  development  activities,
increasing  the opportunities for new products.  In 1997, the Company introduced
additional products and expanded in the United States through the acquisition of
Center,  a Food and Drug Administration ("FDA") and United States Department  of
Agriculture  ("USDA")  licensed manufacturer of allergy  immunotherapy  products
located   in  Port  Washington,  New  York,  and  internationally  through   the
acquisitions  of  Heska  UK Limited ("Heska UK", formerly  Bloxham  Laboratories
Limited),  a  veterinary diagnostic laboratory in Teignmouth,  England  and  CMG
(formerly Centre Medical des Grand'Places S.A.) in Fribourg, Switzerland,  which
manufactures  and markets allergy diagnostic products for use in veterinary  and
human  medicine, primarily in Europe.  Each of the Company's acquisitions during
this  period  was  accounted for under the purchase  method  of  accounting  and
accordingly, the Company's financial statements reflect the operations of  these
businesses  only for the periods subsequent to the respective acquisitions.   In
July  1997,  the  Company established a new subsidiary, Heska AG,  located  near
Basel, Switzerland, for the purpose of managing its European operations.

     During  the  first  quarter  of 1998 the Company  acquired  Heska  Waukesha
(formerly  Sensor  Devices,  Inc.),  a  manufacturer  and  marketer  of  patient
monitoring  devices  used  in both animal health and  human  applications.   The
financial  results of Heska Waukesha have been consolidated with  those  of  the
Company  under  the  pooling-of-interests  accounting  method  for  all  periods
presented.

     During  1999 and 2000, the Company restructured and refocused its business.
The  operations of Heska Waukesha were combined with existing operations in Fort
Collins,  Colorado and Des Moines, Iowa during the fourth quarter of 1999.   The
Heska Waukesha facility was closed in December 1999.  In March 2000, the Company
sold Heska UK.  The Company recorded a loss on disposition of approximately $1.0
million during 1999 for this sale.  In June 2000, the Company sold Center.   The
Company recognized a gain on the sale of approximately $151,000.

     The  Company  has  incurred net losses since its inception and  anticipates
that  it  will continue to incur additional net losses in the near  term  as  it
introduces  new  products,  expands its sales  and  marketing  capabilities  and
continues  its research and development activities.  Cumulative net losses  from
inception  of the Company in 1988 through December 31, 2000 have totaled  $174.5
million.  During the year ended December 31, 2000, the Company incurred  a  loss
of  approximately $21.9 million and used cash of approximately $15.9 million for
operations.

     The  Company's primary short-term needs for capital, which are  subject  to
change,  are  for  its continuing research and development efforts,  its  sales,
marketing  and  administrative  activities,  working  capital  associated   with
increased  product  sales and capital expenditures relating  to  developing  and
expanding  its  manufacturing  operations.  The  Company's  ability  to  achieve
profitable  operations  will depend primarily upon its ability  to  successfully
market   its   products,  commercialize  products  that  are   currently   under
development and develop new products. Most of the Company's products are subject
to long development and regulatory approval cycles and there can be no guarantee
that  the  Company  will  successfully  develop,  manufacture  or  market  these
products.   There  can  also  be  no guarantee  that  the  Company  will  attain
profitability or, if achieved, will remain profitable on a quarterly  or  annual
basis  in the future.  Until the Company attains positive cash flow, the Company
may  continue  to finance operations with additional equity and debt  financing.
There can be no guarantee that such financing will be available when required or
will be obtained under favorable terms.

     The  Company  believes  that  its  available  cash,  cash  equivalents  and
marketable  securities, together with cash from operations, available borrowings
and  borrowings  expected  to be available under its revolving  line  of  credit
facility  will be sufficient to satisfy projected cash requirements  into  2002,
although  it may raise additional funds at or before such time.  Thereafter,  if
cash generated from operations is insufficient to satisfy its cash requirements,
the  Company  will  need  to raise additional captial to continue  its  business
operations.   If necessary, the Company expects to raise these additional  funds
through  one  or more of the following:  (1) sale of additional securities;  (2)
sale  of  various assets; (3) licensing of technology; and (4) sale  of  various
products or marketing rights.  If the Company cannot raise the additional  funds
through  these  options  on  acceptable terms  or  with  the  necessary  timing,
management  could also reduce discretionary spending to decrease  the  Company's
cash  burn  rate  and  extend the currently available  cash,  cash  equivalents,
marketable securities and available borrowings.  See Note 15.

2.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

     The accompanying consolidated financial statements include the accounts  of
the Company and of its wholly-owned subsidiaries since their respective dates of
acquisitions when accounted for under the purchase method of accounting, and for
all  periods presented when accounted for under the pooling-of-interests  method
of  accounting.  All material intercompany transactions and balances  have  been
eliminated in consolidation.

Use of Estimates

     The  preparation  of  financial statements in  conformity  with  accounting
principles generally accepted in the United States requires management  to  make
estimates  and  assumptions  that  affect the reported  amounts  of  assets  and
liabilities, the disclosure of contingent assets and liabilities at the date  of
the  financial  statements  and the reported amounts of  revenues  and  expenses
during the reporting period.  Actual results could differ from those estimates.

Cash and Cash Equivalents

     Cash  and  cash equivalents are stated at cost, which approximates  market,
and  include  short-term highly liquid investments with original  maturities  of
less than three months.

Marketable Securities and Restricted Investments

     The  Company  classifies its marketable securities as  "available-for-sale"
and,  accordingly, carries such securities at aggregate fair value.   Unrealized
gains  or losses, if material, are included as a component of accumulated  other
comprehensive income.

     At  December  31,  2000  these  securities,  consisting  entirely  of  U.S.
government  agency obligations, had an aggregate amortized cost, using  specific
identification, of $2.8 million, with a maximum maturity of approximately  three
years.   At December 31, 1999 these securities had an aggregate amortized  cost,
using  specific  identification,  of  $23.1  million,  a  maximum  maturity   of
approximately  4  years and consisted of $7.8 million of U.S. government  agency
obligations  and  $15.3 million of U.S. corporate commercial  paper.   The  fair
market  value  of  marketable  securities at December  31,  2000  and  1999  was
approximately   $2.8  million  and  $22.8  million,  respectively.    Marketable
securities at both December 31, 2000 and 1999 included approximately $281,000 of
restricted  investments held as collateral for capital leases (See Note  4)  and
$2.5   million   and   $22.5   million  of  short-term  marketable   securities,
respectively.   The  Company realized losses on the sale of  certain  marketable
securities of $111,000 and $943,000 in 2000 and 1999,  respectively,  and a gain
of $216,000 in 1998.

Concentration of Credit Risk

     Financial   instruments  that  potentially  subject  the   Company   to   a
concentration  of  credit risk consist of cash and cash equivalents,  marketable
securities and accounts receivable.  The Company maintains the majority  of  its
cash,  cash  equivalents  and marketable securities with financial  institutions
that  management believes are creditworthy in the form of demand deposits,  U.S.
government agency obligations and U.S. corporate commercial paper.  The  Company
has  no  significant  off-balance sheet concentrations of credit  risk  such  as
foreign   exchange  contracts,  options  contracts  or  other  foreign   hedging
arrangements.  Its accounts receivable balances are due primarily from  domestic
veterinary   clinics  and  individual  veterinarians,  and  both  domestic   and
international corporations.

Fair Value of Financial Instruments

     The  Company's financial instruments consist of cash and cash  equivalents,
short-term  trade receivables and payables, notes receivable and notes  payable.
The   carrying  values  of  cash  and  cash  equivalents  and  short-term  trade
receivables  and  payables approximate fair value.   The  fair  value  of  notes
payable  is  estimated based on current rates available for  similar  debt  with
similar  maturities and collateral, and at December 31, 2000,  approximates  the
carrying value.

Inventories, net

     Inventories  are stated at the lower of cost or market using the  first-in,
first-out  method.   If  the  cost of inventories  exceeds  fair  market  value,
provisions are made for the difference between cost and fair market value.

     Inventories, net of provisions, consist of the following (in thousands):

Derivative Instruments and Hedging Activities

     During  2001,  the  Company  will adopt the provisions  of  SFAS  No.  133,
Accounting  for  Derivative Instruments and Hedging Activities.   The  Statement
establishes  accounting and reporting standards requiring that every  derivative
instrument   (including  certain  derivative  instruments  embedded   in   other
contracts)  be  recorded in the balance sheet as either an  asset  or  liability
measured at fair value.  The Statement requires that changes in the derivative's
fair  value be recognized currently in earnings unless specific hedging criteria
are  met.  The Company does not expect that the adoption of this Statement  will
have a material impact on its reported earnings or comprehensive income.

Property, Equipment and Intangible Assets

     Property  and equipment are recorded at cost and depreciated on a straight-
line  or  declining balance basis over the estimated useful lives of the related
assets.   Amortization of assets acquired under capital leases is included  with
depreciation expense on owned assets.

     Leasehold  improvements are amortized over the applicable lease  period  or
their estimated useful lives, whichever is shorter.  Maintenance and repairs are
charged  to  expense  when  incurred, and major renewals  and  improvements  are
capitalized.

     Intangible assets primarily consist of various assets arising from business
combinations and are amortized using the straight-line method over the period of
expected benefit.

     The  Company periodically reviews the appropriateness of the remaining life
of  its property, equipment and intangible assets considering whether any events
have occurred or conditions have developed which may indicate that the remaining
life  requires adjustment.  After reviewing the appropriateness of the remaining
life  and the pattern of usage of these assets, the Company then assesses  their
overall  recoverability by determining if the net book value  can  be  recovered
through  undiscounted  future  operating cash  flows.   Absent  any  unfavorable
findings,  the  Company  continues  to amortize  and  depreciate  its  property,
equipment  and intangible assets based on the existing estimated  life.   During
2000,  the  Company's  review  of  property,  equipment  and  intangible  assets
determined that a write-down to fair market value of $355,000 for equipment  was
needed.   In  1999, the Company's review of property, equipment  and  intangible
assets  determined that a write-down to fair market value of  $1.0  million  for
equipment  and  $372,000 for intangible assets was needed.  These  amounts  were
recorded as part of the loss on sale of assets in the accompanying statement  of
operations.

     Property and equipment consist of the following (in thousands):

     The  customer  lists and market presence resulted from the  Company's  1997
acquisition of CMG.  The remaining intangible assets resulted primarily from the
acquisitions  of  certain assets in 1998.  Amortization expense  for  intangible
assets  was $255,000, $1.6 million and $2.0 million for the years ended December
31, 2000, 1999 and 1998, respectively.

Revenue Recognition

     Product  revenues  are  recognized at the time goods  are  shipped  to  the
customer with an appropriate provision for returns and allowances.

     License  revenues received under arrangements to license patent  rights  or
technology  rights  are  deferred and amortized over the  life  of  the  related
arrangement.  Royalties are recognized as products are sold to customers.

     The Company recognizes revenue from sponsored research and development over
the  life  of  the contract as research activities are performed.   The  revenue
recognized  is  the  lesser of revenue earned under a percentage  of  completion
method  based on total expected revenues or actual non-refundable cash  received
to  date  under the agreement.  In connection with these sponsored research  and
development  agreements, the Company has recognized $1.4 million,  $900,000  and
$1.3   million  of  research  and  development  revenue  for  the  years   ended
December 31, 2000, 1999 and 1998, respectively.

     In   addition  to  its  direct  sales  force,  the  Company  utilizes  both
distributors  and sales agency organizations to sell its products.  Distributors
purchase  goods from the Company, take title to those goods and resell  them  to
their   customers  in  the  distributors'  territory.   Sales  agents   maintain
inventories  of  goods on consignment from the Company and sell these  goods  on
behalf  of the Company to customers in the sales agents' territory.  The Company
recognizes  revenue  at the time goods are sold to the customers  by  the  sales
agents.   Sales  agents  are  paid  a  fee for  their  services,  which  include
maintaining  product  inventories, sales activities,  billing  and  collections.
Fees  earned  by  sales agents are netted against revenues  generated  by  these
entities.

     In December 1999, the SEC issued SAB No. 101, Revenue Recognition.  SAB 101
clarifies  the  SEC  staff's  views in applying  generally  accepted  accounting
principles  to selected revenue recognition issues.  We adopted SAB  101  during
the  quarter ended December 31, 2000.  The adoption of SAB 101 did  not  have  a
material  impact on our financial statements, and therefore, did not  result  in
the recording of a cumulative effect of change in an accounting principle as  if
SAB  101  had  been  adopted  on January 1, 2000,  or  the  restatement  of  the
previously reported quarterly results for 2000.

Cost of Sales

     Royalties  payable  in  connection with certain research,  development  and
licensing agreements (See Note 9) are reflected in cost of sales as incurred.

Basic and Diluted Net Loss Per Share

     Basic  net  loss  per common share is computed using the  weighted  average
number  of  common shares outstanding during the period.  Diluted net  loss  per
share  is  computed using the sum of the weighted average number  of  shares  of
common  stock  outstanding and, if not anti-dilutive, the effect of  outstanding
stock  options  and  warrants determined using the treasury  stock  method.   At
December 31, 2000, securities that have been excluded from diluted net loss  per
share  because they would be anti-dilutive are outstanding options  to  purchase
3,964,668  shares  of  the  Company's common  stock  and  warrants  to  purchase
1,165,000 shares of the Company's common stock.

Foreign Currency Translation

     The  functional currency of the Company's international subsidiaries is the
Swiss  Franc  ("CHF").   Assets and liabilities of the  Company's  international
subsidiaries  are translated using the exchange rate in effect  at  the  balance
sheet  date.   Revenue and expense accounts are translated using an  average  of
exchange  rates in effect during the period.  Cumulative translation  gains  and
losses,  if material, are shown in the consolidated balance sheets as a separate
component  of  stockholders' equity.  Exchange gains  and  losses  arising  from
transactions  denominated  in foreign currencies (i.e.,  transaction  gains  and
losses)  are  recognized in current operations.  The Company does not  generally
enter into any forward contracts or hedging transactions.

3.   BUSINESS ACQUISITION

     Acquisition  of  Heska Waukesha.  In March 1998 the Company  completed  its
acquisition  of all of the outstanding shares of Heska Waukesha, a  manufacturer
and marketer of medical sensor products, in a
transaction  valued at approximately $8.9 million using the pooling-of-interests
accounting  method.  The Company issued 639,622 shares of its common  stock  and
also  reserved an additional 147,898 shares of its common stock for issuance  in
connection  with  outstanding Heska Waukesha options that were  assumed  by  the
Company  in  the  merger.   Accordingly, in  1998,  the  consolidated  financial
statements  of  the  Company  were restated to include  the  accounts  of  Heska
Waukesha for all prior periods presented.  There were no adjustments required to
the  net  assets or previously reported results of operations of the Company  or
Heska  Waukesha as a result of the adoption of the same accounting practices  by
the respective entities.

4.   CAPITAL LEASE OBLIGATIONS

     The   Company  has  entered  into  certain  capital  lease  agreements  for
laboratory  equipment, office equipment, machinery and equipment,  and  computer
equipment  and  software.  For the years ended December 31, 2000 and  1999,  the
Company  had  capitalized machinery and equipment under capital  leases  with  a
gross value of approximately $2.5 million and $2.5 million and net book value of
approximately $740,000 and $1.2 million, respectively.  The capitalized cost  of
the  equipment  under  capital leases is included in  the  accompanying  balance
sheets  under  the respective asset classes.  Under the terms of  the  Company's
lease  agreements, the Company is required to make monthly payments of principal
and  interest  through the year 2004, at interest rates ranging  from  4.05%  to
20.00% per annum.  The equipment under the capital leases serves as security for
the leases.

     The  Company has a capital lease with a commercial bank which requires  the
Company  to  pledge cash or investments as additional collateral for the  lease.
The  lease  agreement, which has a borrowing limit of $2.0 million calls  for  a
collateral balance equal to 25% of the borrowed amount when the Company's annual
revenues  reach $28.0 million.  The lease also requires the Company to  maintain
minimum levels of cash and cash equivalent balances throughout the term  of  the
lease.   At both December 31, 2000 and 1999, the Company was in compliance  with
all  covenants  of the master lease and held restricted U.S. Treasury  Bonds  of
approximately $281,000 as additional collateral under the lease.

     The future annual minimum required payments under capital lease obligations
as of December 31, 2000 were as follows (in thousands):

5.   RESTRUCTURING EXPENSES

     During  the  first  quarter of fiscal 2000, the Company  initiated  a  cost
reduction  and  restructuring plan at its Diamond subsidiary.  The restructuring
resulted from the rationalization of Diamond's business including a reduction in
the  size  of  its  workforce  and the Company's decision  to  vacate  a  leased
warehouse  and  distribution  facility no  longer  needed  after  the  Company's
decision  to  discontinue  contract manufacturing of certain  low  margin  human
healthcare products.  The charge to operations of approximately $435,000 related
primarily  to  personnel  severance  costs for  12  individuals  and  the  costs
associated  with  closing  the  leased  facility,  terminating  the  lease   and
abandoning  certain leasehold improvements.  The facility was  closed  in  April
2000.

     In  August  1999,  the  Company announced plans to  consolidate  its  Heska
Waukesha operations with existing operations in Fort Collins, Colorado  and  Des
Moines, Iowa.  This consolidation was based on the Company's determination  that
significant  operating  efficiencies could  be  achieved  through  the  combined
operations.  The Company recognized a charge to operations of approximately $1.2
million  for this consolidation.  These expenses related primarily to  personnel
severance  costs  for  40 individuals and the costs associated  with  facilities
being  closed  and  excess  equipment,  primarily  at  the  Company's  Waukesha,
Wisconsin location.  This facility was closed in December 1999.

     Shown  below is a reconciliation of restructuring costs for the year  ended
December 31, 2000 (in thousands):

     In  June 2000, the Company entered into a two-year expanded credit facility
with  Wells Fargo Business Credit, Inc., an affiliate of Wells Fargo Bank.   The
credit  facility  includes an asset-based revolving line of credit.   Under  the
agreement,  the  Company is required to comply with certain financial  and  non-
financial covenants.  Among the financial covenants are requirements for monthly
minimum  book net worth, quarterly minimum net income and minimum cash  balances
or liquidity levels.  The Company was in compliance with all financial covenants
at December 31, 2000.  See Note 15.


     Amounts  due under the Company's equipment term loan, real estate  mortgage
loan  and  revolving credit facility are payable to a commercial  bank  and  are
secured by a first security interest in essentially all of the Company's assets.

     The  IDED  and City of Des Moines promissory notes are secured by  a  first
security  interest in essentially all assets of Diamond except  assets  acquired
through  capital leases and are included as cross-collateralized obligations  by
the  respective lenders.  The IDED has subordinated all of its security interest
in  these assets to a commercial bank providing credit to the Company.  The City
of  Des  Moines has subordinated up to $15 million of its security  interest  in
these  assets to the same commercial bank.  These notes were assumed as a result
of the 1996 Diamond acquisition.

     The  Company's  other debt instruments are secured by  the  assets  of  the
respective subsidiaries and general corporate guarantees by Heska Corporation.

7.   ACCRUED PENSION LIABILITY

     Diamond  has  a noncontributory defined benefit pension plan  covering  all
employees who have met the eligibility requirements.  The plan provides  monthly
benefits  based on years of service which are subject to certain  reductions  if
the  employee  retires before reaching age 65.  Diamond's funding policy  is  to
make the minimum annual contribution that is required by applicable regulations.
Effective October 1992, Diamond froze the plan, restricting new participants and
benefits for future service.

     The  following  table  sets  forth the plan's  funded  status  and  amounts

8.   INCOME TAXES

     As of December 31, 2000 the Company had approximately $154.6 million of net
operating  loss ("NOL") carryforwards for income tax purposes and  approximately
$3.1  million of research and development tax credits available to offset future
federal income tax, subject to limitations for alternative minimum tax.  The NOL
and  credit carryforwards are subject to examination by the tax authorities  and
expire  in  various years from 2003 through 2020.  The Tax Reform  Act  of  1986
contains  provisions  that may limit the NOL and credit carryforwards  available
for  use  in  any  given year upon the occurrence of certain  events,  including
significant changes in ownership interest.  A change in ownership
of a company of greater than 50% within a three-year period results in an annual
limitation  on the Company's ability to utilize its NOL carryforwards  from  tax
periods prior to the ownership change.  The acquisition of Diamond in April 1996
resulted  in  such  a  change of ownership and the Company  estimates  that  the
resulting  NOL  carryforward limitation will be approximately $4.7  million  per
year  for periods subsequent to April 19, 1996.  The Company believes that  this
limitation may affect the eventual utilization of its total NOL carryforwards.

     The  Company's  NOL's  represent  a previously  unrecognized  tax  benefit.
Recognition of these benefits requires future taxable income, the attainment  of
which  is  uncertain, and therefore, a valuation allowance has been  established
for  the  entire tax benefit and no benefit for income taxes has been recognized
in the accompanying consolidated statements of operations.

9.   COMMITMENTS AND CONTINGENCIES

     In  November  1998, Synbiotics Corporation ("Synbiotics") filed  a  lawsuit
against  the  Company  in  the United States District  Court  for  the  Southern
District  of California in which it alleges that the Company infringed a  patent
owned  by  Synbiotics relating to heartworm diagnostic technology.  The  Company
has  answered  the complaint and no trial date has been set.   The  Company  has
obtained   legal  opinions  from  outside  patent  counsel  that  its  heartworm
diagnostic products do not infringe the Synbiotics patent and that the patent is
invalid.   The opinions of non-infringement are consistent with the  results  of
the  Company's internal evaluations.  In September 2000, the U.S. District Court
hearing  the case granted the Company's request for a partial summary  judgment,
holding  two  of  the Synbiotics patent claims to be invalid, leaving  only  one
remaining    claim.     While    management   believes    that    the    Company
has  valid  defenses  to  Synbiotics' allegations  and  intends  to  defend  the
action  vigorously,  there  can  be  no assurance  that  an  adverse  result  or
settlement  would not have a material adverse effect on the Company's  financial
position, its results of operations or cash flow.

     The  Company  holds certain rights to market and manufacture  all  products
developed   or  created  under  certain  research,  development  and   licensing
agreements  with  various  entities. In connection  with  such  agreements,  the
Company has agreed to pay the entities royalties on net product sales.   In  the
years  ended  December  31,  2000, 1999 and 1998, royalties  of  $931,000,  $1.0
million and $52,000 became payable under these agreements, respectively.

     The  Company  contracts  with various parties  that  conduct  research  and
development on the Company's behalf.  In return, the Company generally  receives
the  right to commercialize any products resulting from these contracts.  In the
event  the Company licenses any technology developed under these contracts,  the
Company will generally be obligated to pay royalties at specified percentages of
future sales of products utilizing the licensed technology.

     The  Company has entered into operating leases for its office and  research
facilities and certain equipment with future minimum payments as of December 31,
2000 as follows (in thousands):

additional  1.165  million shares of the Company's common stock.   The  exercise
price  of the warrants was $12.67 for the first year of the warrants, increasing
by  20%  per  year for each of the second and third years of the warrants.   The
warrants  were exercisable immediately as of July 30, 1998 and expire  in  three
years with respect to any unexercised shares.

     In  July  1998, the Company issued 205,619 shares of common stock to  Bayer
Corporation ("Bayer") in consideration for the acquisition by Diamond of certain
assets, including land and buildings formerly leased by Diamond from Bayer,  and
as  repayment  in  full  of  certain indebtedness of  Diamond  to  Bayer,  in  a
transaction valued at approximately $2.3 million.

     In  March  1998,  the  Company completed its follow-on public  offering  of
5,750,000  shares  of  common  stock (including  500,000  shares  offered  by  a
stockholder of the Company and an underwriters' over-allotment option  exercised
for  750,000 shares) at a price of $9.875 per share, providing the Company  with
net proceeds of approximately $48.6 million.

Stock Option Plans

     The  Company  has  a stock option plan which authorizes granting  of  stock
options  and  stock  purchase  rights  to  employees,  officers,  directors  and
consultants  of the Company to purchase shares of common stock.   In  1997,  the
board  of  directors  adopted the 1997 Stock Incentive Plan and  terminated  two
prior  option plans.  However, options granted and unexercised under  the  prior
plans are still outstanding.  All shares remaining available for grant under the
terminated plans were rolled into the 1997 Plan.  In addition, all shares  which
are  subsequently cancelled under the prior plans are rolled into the 1997  Plan
on a quarterly basis.  The number of shares reserved for issuance under the 1997
Plan increases automatically on January 1 of each year by a number equal to  the
lesser  of  (a)  1,500,000  shares or (b) 5%  of  the  shares  of  common  stock
outstanding  on  the immediately preceding December 31.  The  number  of  shares
reserved for issuance under all plans as of January 1, 2001 was 7,643,853.

     The stock options granted by the board of directors may be either incentive
stock  options  ("ISOs") or non-qualified stock options ("NQs").   The  purchase
price for options under all of the plans may be no less than 100% of fair market
value for ISOs or 85% of fair market value for NQs.  Options granted will expire
no  later  than the tenth anniversary subsequent to the date of grant  or  three
months  following  termination  of employment,  except  in  cases  of  death  or
disability, in which case the options will remain exercisable for up  to  twelve
months.   Under the terms of the 1997 Plan, in the event the Company is sold  or
merged,  options granted will either be assumed by the surviving corporation  or
vest immediately.

SFAS No. 123 ("SFAS 123")

     SFAS  123,  Accounting for Stock-Based Compensation, defines a  fair  value
based method of accounting for employee stock options, employee stock purchases,
or   similar  equity  instruments.   However,  SFAS  123  allows  the  continued
measurement of compensation cost for such plans using the intrinsic value  based
method  prescribed  by APB Opinion No. 25, Accounting  for   Stock   Issued   to
Employees ("APB 25"), provided that pro forma disclosures are made of net income
or  loss,  assuming the fair value based  method of SFAS 123 had  been  applied.
The  Company has elected to account for its stock-based compensation plans under
APB  25; accordingly, for purposes of the pro forma disclosures presented below,
the  Company  has computed the fair values of all options granted  during  2000,
1999  and 1998, using the Black-Scholes pricing model and the following weighted
average assumptions:




                                            2000         1999         1998
                                            ----         ----         ----
                                                             
        Risk-free interest rate             6.26%        5.63%        5.28%
        Expected lives                      7.59 years   3.5 years    3.8 years
        Expected volatility                 94%          91%          89%
        Expected dividend yield             0%           0%           0%



     To  estimate  expected lives of options for this valuation, it was  assumed
options  will  be  exercised at varying schedules after  becoming  fully  vested
dependent upon the income level of the option holder.  For measurement purposes,
options  have  been segregated into three income groups, and estimated  exercise
behavior  of option recipients varies from six months to one and one half  years
from  the  date  of vesting, dependent on income group (less highly  compensated
employees  are  expected  to  have shorter holding periods).   All  options  are
initially assumed to vest.  Cumulative compensation cost recognized in pro forma
basic  net  income or loss with respect to options that are forfeited  prior  to
vesting  is  adjusted as a reduction of pro forma compensation  expense  in  the
period  of  forfeiture.   Fair value computations are highly  sensitive  to  the
volatility  factor assumed; the greater the volatility, the higher the  computed
fair value of the options granted.

     The  total  fair value of options granted was computed to be  approximately
$1.7  million,  $3.8 million and $8.8 million for the years ended  December  31,
2000,  1999 and 1998, respectively.  The amounts are amortized ratably over  the
vesting periods of the options.  Pro forma stock-based compensation, net of  the
effect of forfeitures, was $2.2 million, $3.6 million and $3.9 million for 2000,
1999 and 1998, respectively.

     A summary of the Company's stock option plans is as follows:

     The  weighted  average estimated fair value of options granted  during  the
years  ended December 31, 2000, 1999 and 1998 were $2.3277, $2.1814 and $6.7635,
respectively.

     In 1998 the Company also granted stock options to non-employees in exchange
for consulting services, recording deferred compensation of $46,000 based on the
estimated fair value of the options at the date of grant.  Deferred compensation
was amortized over the applicable service periods.  The amortization of deferred
compensation  resulted in a non-cash charge to operations of $648,000,  $629,000
and $736,000 in the years ended December 31, 2000, 1999 and 1998, respectively.

Employee Stock Purchase Plan (the "ESPP")

     Under  the 1997 Employee Stock Purchase Plan, the Company is authorized  to
issue  up to 750,000 shares of common stock to its employees.  Employees of  the
Company and its U.S. subsidiaries who are expected to work at least 20 hours per
week  and five months per year are eligible to participate.  Under the terms  of
the  plan, employees can choose to have up to 10% of their annual base  earnings
withheld  to  purchase the Company's common stock.  The purchase  price  of  the
stock  is  85%  of  the lower of its beginning-of-enrollment period  or  end-of-
measurement period market price.  Each enrollment period is two years, with  six
month measurement periods ending June 30 and December 31.

     For  the years ended December 31, 2000, 1999 and 1998, the weighted-average
fair  value of the purchase rights granted was $0.91, $1.24 and $4.57 per share,
respectively.   Pro  forma  stock-based  compensation,  net  of  the  effect  of
adjustments, was approximately $112,462, $96,000 and $268,000 in 2000, 1999  and
1998, respectively, for the ESPP.

Stock Warrants

     In  July 1998, the Company issued warrants to purchase 1.165 million shares
of  the  Company's  common stock in connection with the private  placement  with
Ralston  Purina  described previously.  The exercise price of the  warrants  was
$12.67  for the first year of the warrants, increasing by 20% per year for  each
of  the  second and third years of the warrants.  The warrants were  exercisable
immediately  as of July 30, 1998 and expire in three years with respect  to  any
unexercised shares.

11.  MAJOR CUSTOMERS

     The  Company  had sales of greater than 10% of total revenue  to  only  one
customer  during the years ended December 31, 2000, 1999 and 1998.  The customer
which  represented 17% of total revenues in 2000, and a different customer which
represented  12%  and  15%  of total revenues in 1999  and  1998,  respectively,

     (c) Includes the write-down of certain tangible and intangible
         assets  to their expected net realizable values, resulting  from
         a   loss  on  assets  held  for  disposition  of  $1.3  million,

     The Company manufactures and markets its products in two major geographic
areas, North America and Europe.  The Company's primary manufacturing facilities
are located in North America.  Revenues earned in North America are attributable
to Heska, Diamond, Heska Waukesha (through 1999) and Center (through June 2000).
Revenues earned in Europe are primarily attributable to Heska UK (through
January 2000), CMG and Heska AG.  There have been no significant exports from
North America or Europe.

     During each of the years presented, European subsidiaries purchased
products from North America for sale to European customers.  Transfer prices to
international subsidiaries are intended to allow the North American companies to
produce profit margins commensurate with their sales and
marketing efforts.  Certain information by geographic area is shown in the
following table (in thousands).  The "Other" column includes the elimination of
intercompany transactions.

     On  February  6,  2001, the Company sold 4,573,000 shares of  common  stock
through  a  private  placement offering with net  proceeds  to  the  Company  of
approximately  $5.3  million.  The Company has agreed  to  register  the  shares
issued under the private placement as soon as practicable.

     On  March  23,  2001,  the Company re-negotiated the  covenants  under  its
revolving  line of credit facility.  The Company's ability to borrow under  this

to  be  maintained has been reduced to $3 million during 2001.  As of March  23,
2001, the Company's available borrowing capacity was approximately $5 million.
