THE EXCHANGE OFFER AND WITHDRAWAL RIGHTS WILL EXPIRE AT 5:00 P.M., NEW YORK CITY
TIME ON JUNE       , 2002, UNLESS EXTENDED (SUCH DATE AND TIME, AS THE SAME MAY

                                                                    May   , 2002

To Our Clients:

    Enclosed for your consideration is a prospectus dated May   , 2002 (the
"Prospectus") and a letter of transmittal (the "Letter of Transmittal") that
together constitute the offer (the "Exchange Offer") by PETCO Animal
Supplies, Inc., a Delaware corporation ("PETCO"), to exchange up to $170,000,000
in principal amount of its 10.75% Senior Subordinated Notes due 2011 (the
"Exchange Notes"), which have been registered under the Securities Act of 1933,
as amended (the "Securities Act"), for any and all outstanding 10.75% Senior
Subordinated Notes due 2011 issued and sold in a transaction exempt from
registration under the Securities Act (the "Old Notes"), upon the terms and
subject to the conditions set forth in the Prospectus. The Prospectus and Letter
of Transmittal more fully describe the Exchange Offer.

    These materials are being forwarded to you as the beneficial owner of Old
Notes carried by us for your account or benefit but not registered in your name.
A tender of any Old Notes may be made only by us as the registered holder and
pursuant to your instructions. Therefore, PETCO urges beneficial owners of Old
Notes registered in the name of a broker, dealer, commercial bank, trust company
or other nominee to contact such registered holder promptly if they wish to
tender Old Notes in the Exchange Offer.

    Accordingly, we request instructions as to whether you wish us to tender any
or all of your Old Notes held by us for your account pursuant to the terms and
subject to the conditions set forth in the Prospectus and Letter of Transmittal.
We urge you to read carefully the Prospectus and Letter of Transmittal before
instructing us to tender your Old Notes.

    Your instructions to us should be forwarded as promptly as possible in order
to permit us to tender Old Notes on your behalf in accordance with the
provisions of the Exchange Offer.

    Your attention is directed to the following:

    1.  The Exchange Offer will expire at 5:00 p.m., New York City time on June
  , 2002, unless extended (such date and time, as the same may be extended, the
"Expiration Date"). Tendered Old Notes may be withdrawn, subject to the
procedures described in the Prospectus, at any time before the Expiration Date.

    2.  The Old Notes will be exchanged for the Exchange Notes at the rate of
$1,000 principal amount of Exchange Notes for each $1,000 principal amount of
Old Notes validly tendered and not withdrawn before the Expiration Date. The
Exchange Notes will bear interest from the most recent interest payment date to
which interest has been paid on the Old Notes. The Exchange Notes are
substantially identical to the Old Notes, except that the Exchange Notes have
been registered under the federal securities laws and will not bear any legend
restricting their transfer.

    3.  Notwithstanding any other term of the Exchange Offer, PETCO may
terminate or amend the Exchange Offer as provided in the Prospectus and will not
be required to accept for exchange, or exchange any Exchange Notes for, any Old
Notes not accepted for exchange prior to such termination.

    4.  Any transfer taxes applicable to the exchange of the Old Notes pursuant
to the Exchange Offer will be paid by PETCO, except as otherwise provided in the
Prospectus and in Instruction 8 of the Letter of Transmittal.

    5.  Based on an interpretation of the Securities Act by the staff of the
Securities and Exchange Commission, PETCO believes that Exchange Notes issued
pursuant to the Exchange Offer in exchange for Old Notes may be offered for
resale, resold and otherwise transferred by holders thereof without compliance
with the registration and prospectus delivery provisions of the Securities Act,
provided that the holder:

        (a) is acquiring Exchange Notes in its ordinary course of business;

        (b) is not engaging in, does not intend to engage in, and has no
    arrangement or understanding with any person to participate in, the
    distribution of the Exchange Notes;

        (c) is not an "affiliate" of PETCO, as such term is defined in Rule 405
    under the Securities Act; and

        (d) the holder is not acting on behalf of any person who could not
    truthfully make these statements.

    To participate in the Exchange Offer, holders must represent to PETCO that
each of these statements is true. If the holder is a broker-dealer that will
receive Exchange Notes for its own account in exchange for Old Notes that were
acquired as a result of market-making activities or other trading activities, it
must acknowledge that it will deliver a prospectus meeting the requirements of
the Securities Act in connection with any resale of such Exchange Notes.

    If you wish to have us tender any or all of your Old Notes held by us for
your account or benefit, please so instruct us by completing, executing and
returning to us the instruction form entitled "Instruction to Registered Holders
and DTC Participants From Beneficial Owner" that appears below. An envelope to
return your instructions is enclosed. If you authorize a tender of your Old
Notes, the entire principal amount of Old Notes held for your account will be
tendered unless otherwise specified on the instruction form. Your instructions
should be forwarded to us in ample time to permit us to submit a tender on your
behalf by the Expiration Date.

    THE ACCOMPANYING LETTER OF TRANSMITTAL IS FURNISHED TO YOU FOR INFORMATIONAL
PURPOSES ONLY AND MAY NOT BE USED BY YOU TO TENDER OLD NOTES HELD BY US AND
REGISTERED IN OUR NAME FOR YOUR ACCOUNT OR BENEFIT. A TENDER OF ANY OLD NOTES
MAY BE MADE ONLY BY US AS THE REGISTERED HOLDER AND PURSUANT TO YOUR
INSTRUCTIONS.

         prospectus delivery requirements of the Securities Act in connection
         with a secondary resale transaction of the Exchange Notes or interests
