FORT COLLINS, CO, May 7, 2002 -- Heska Corporation (Nasdaq: HSKA), a company
focused on innovative products for the companion animal healthcare market,
announced today that Jason Napolitano has been appointed Chief Financial
Officer, succeeding Ron Hendrick who has retired from the company.

"Jason has been a trusted outside adviser to Heska for many years, providing
strategic business judgement and sound financial guidance.  We look forward to
benefiting from his analytical skills and full-time focus applied to more
aspects of our daily business as we continue our progress toward profitability,"
Chairman and Chief Executive Officer Robert Grieve said.

Napolitano joins Heska with a broad background in investment banking and
financial consulting expertise.  He was a Director in the Mergers & Acquisitions
department of Credit Suisse First Boston, a firm he spent over 10 years with and
where his previous experience included four years of health care investment
banking.  His responsibilities at Heska will include finance, investor relations
and corporate development.

"We also appreciate the commitment over the years of Ron Hendrick, Jason's
predecessor, in helping Heska divest certain businesses, raise capital and cut
costs, all with the goal of putting the company on a more sound financial
footing," Grieve said.

The company also announced that Jim Fuller, president and chief operating
officer, has informed the company that he intends to retire in June 2002.  His
responsibilities will be assumed  by Robert Grieve.

business grew substantially, as Jim was instrumental in helping to position
Heska as a true leader in our industry."
