The undersigned understands that tenders of the Old Notes pursuant to any one of the procedures described in the Prospectus under the caption "The Exchange Offer--Procedures for Tendering" and in the instructions to this Letter of Transmittal will, upon PETCO's acceptance of the Old Notes for exchange, constitute a binding agreement between the undersigned and PETCO in accordance with the terms and subject to the conditions of the Exchange Offer. 5. The Exchange Offer is subject to the conditions set forth in the Prospectus under the caption "The Exchange Offer--Conditions to the Exchange Offer." The undersigned recognizes that as a result of these conditions (which may be waived, in whole or in part, by PETCO) as more particularly set forth in the Prospectus, PETCO may not be required to exchange any of the Old Notes tendered by this Letter of Transmittal and, in such event, the Old Notes not exchanged will be returned to the undersigned at the address shown below the signature of the undersigned. 6.

Such election may be made by checking the box under "Special Registration Instructions" below. By making such election, the undersigned agrees, severally and not jointly, as a holder of transfer restricted securities participating in a shelf registration, to indemnify and hold harmless PETCO and all other holders of Registrable Securities (as defined in the Exchange and Registration Rights Agreement) against any losses, claims, damages or liabilities (or actions in respect thereof) (including, without limitation, the reasonable legal and other expenses incurred in connection with investigating or defending any such action or claim) arising out of or based upon (i) an untrue statement or alleged untrue statement of a material fact contained in the shelf registration statement filed with respect to such Old Notes or the Prospectus or in any amendment thereof or supplement thereto or (ii) the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading; in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with information relating to the undersigned furnished to PETCO in writing by or on behalf of the undersigned expressly for use therein.

If the undersigned 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 acknowledges that it will deliver a prospectus meeting the requirements of the Securities Act in connection with any resale of such Exchange Notes. However, by so acknowledging and by delivering a prospectus, the undersigned does not and will not be deemed to admit that it is an "underwriter" within the meaning of the Securities Act.

All authority conferred or agreed to be conferred by this Letter of Transmittal shall not be affected by and shall survive the death, bankruptcy or incapacity of the undersigned, and every obligation of the undersigned hereunder shall be binding upon the heirs, personal representatives, executors, administrators, successors, assigns, trustees in bankruptcy and other legal representatives of the undersigned. 10.

DELIVERY OF LETTER OF TRANSMITTAL AND OLD NOTES. This Letter of Transmittal must be completed by holders of Old Notes if certificates representing such Old Notes are to be forwarded herewith or, unless an Agent's Message is utilized, if tender is to be made by book-entry transfer to the account maintained by the Exchange Agent at DTC, pursuant to the procedures set forth in the Prospectus under "The Exchange Offer--Procedures for Tendering." For a holder to properly tender Old Notes pursuant to the Exchange Offer, a properly completed and duly executed Letter of Transmittal or a copy of the Letter of Transmittal, together with any signature guarantees and any other documents required by these Instructions, or a properly transmitted Agent's Message in the case of a book-entry transfer, must be received by the Exchange Agent at its address set forth on the cover of this Letter of Transmittal before the Expiration Date, and either (1) certificates representing such Old Notes must be received by the Exchange Agent at its address or (2) such Old Notes must be transferred into the Exchange Agent's account at DTC pursuant to the procedures for book-entry transfer described in the Prospectus under "The Exchange Offer-Book-Entry Transfer" and a book-entry confirmation must be received by the Exchange Agent, before the Expiration Date. A holder who desires to tender Old Notes and who cannot comply with the procedures set forth herein for tender on a timely basis or whose Old Notes are not immediately available must comply with the guaranteed delivery procedures discussed below. THE METHOD OF DELIVERY OF THIS LETTER OF TRANSMITTAL, THE OLD NOTES AND ALL OTHER REQUIRED DOCUMENTS TO THE EXCHANGE AGENT IS AT THE ELECTION AND RISK OF THE HOLDER AND DELIVERY WILL BE DEEMED TO BE MADE ONLY WHEN ACTUALLY RECEIVED BY THE EXCHANGE AGENT. INSTEAD OF DELIVERY BY MAIL, HOLDERS SHOULD USE AN OVERNIGHT OR HAND DELIVERY SERVICE, PROPERLY INSURED. IF CHOOSING DELIVERY BY MAIL, HOLDERS SHOULD USE REGISTERED MAIL, RETURN RECEIPT REQUESTED, PROPERLY INSURED. IN ALL CASES, HOLDERS SHOULD ALLOW FOR SUFFICIENT TIME TO ENSURE DELIVERY TO THE EXCHANGE AGENT BEFORE THE EXPIRATION DATE. HOLDERS SHOULD NOT SEND ANY NOTE, LETTER OF TRANSMITTAL OR OTHER REQUIRED DOCUMENT TO PETCO. HOLDERS MAY REQUEST THEIR BROKER, DEALER, COMMERCIAL BANK, TRUST COMPANY OR NOMINEE TO EFFECT THESE TRANSACTIONS FOR SUCH HOLDER. If a holder desires to tender Old Notes pursuant to the Exchange Offer and (1) certificates representing such Old Notes are not immediately available, (2) time will not permit such holder's Letter of Transmittal, certificates representing such Old Notes or other required documents to reach the Exchange Agent before the Expiration Date or (3) the procedures for book-entry transfer (including delivery of an Agent's Message) cannot be completed before the Expiration Date, such holder may nevertheless tender such Old Notes with the effect that such tender will be deemed to have been received before the Expiration Date if the guaranteed delivery procedures set forth in the Prospectus under "The Exchange Offer--Guaranteed Delivery Procedures" are followed. Pursuant to such procedures, (1) the tender must be made by or through an eligible guarantor institution (as defined below), (2) a properly completed and duly executed notice of guaranteed delivery, substantially in the form provided by PETCO herewith, or an Agent's Message with respect to a guaranteed delivery that is accepted by PETCO, must be received by the Exchange Agent before the Expiration Date and (3) the certificates for the tendered Old Notes, in proper form for transfer (or a book-entry confirmation of the transfer of such Old Notes into the Exchange Agent's account at DTC as described in the Prospectus), together with this Letter of Transmittal, or a copy of this Letter of Transmittal, properly completed and duly executed, with any required signature guarantees and any other documents required by this Letter of Transmittal, or a properly transmitted Agent's Message, must be received by the Exchange Agent within three trading days after the execution of the notice of guaranteed delivery. The notice of guaranteed delivery may be sent by hand delivery, facsimile transmission or mailed to the Exchange Agent and must include a guarantee by an eligible guarantor institution in the form set forth in the notice of guaranteed delivery. For Old Notes to be properly tendered pursuant to the guaranteed delivery procedure, the Exchange Agent must receive a notice of guaranteed delivery before the Expiration Date. As used herein and in the Prospectus, "eligible guarantor institution" means a firm or other entity identified in Rule 17Ad-15 under the Exchange Act as an "eligible guarantor institution," including (as such terms are defined therein): (1) a bank, (2) a broker, dealer, municipal securities broker or dealer or government securities broker or dealer, (3) a credit union, (4) a national securities exchange, registered securities association or clearing agency or (5) a savings association. 2. GUARANTEE OF SIGNATURES. Signatures on this Letter of Transmittal must be guaranteed by a member of or participant in the Securities Transfer Agents Medallion Program, the New York Stock Exchange Medallion Signature Program, the Stock Exchange Medallion Program or by an eligible guarantor institution unless the Old Notes tendered hereby are tendered (1) by a registered holder of Old Notes (or by a participant in DTC whose name appears on a security position listing as the owner of such Old Notes) who has signed this Letter of <Page> Transmittal and who has not completed any of the boxes entitled "Special Issuance Instructions," "Special Delivery Instructions" or "Special Registration Instructions" on the Letter of Transmittal or (2) for the account of an eligible guarantor institution. If the Old Notes are registered in the name of a person other than the signer of the Letter of Transmittal or if Old Notes not tendered are to be returned to, or are to be issued to the order of, a person other than the registered holder or if Old Notes not tendered are to be sent to someone other than the registered holder, then the signature on this Letter of Transmittal accompanying the tendered Old Notes must be guaranteed as described above. Beneficial owners whose Old Notes are registered in the name of a broker, dealer, commercial bank, trust company or other nominee must contact such broker, dealer, commercial bank, trust company or other nominee if they desire to tender Old Notes. See "The Exchange Offer--Procedures for Tendering" in the Prospectus. 3. WITHDRAWAL OF TENDERS. Except as otherwise provided in the Prospectus, tenders of Old Notes may be withdrawn at any time before the Expiration Date. For a withdrawal of tendered Old Notes to be effective, a written or, for DTC participants, electronic ATOP notice of withdrawal must be received by the Exchange Agent before the Expiration Date at its address set forth on the cover of this Letter of Transmittal. Any such notice of withdrawal must (1) specify the name of the person who tendered the Old Notes to be withdrawn, (2) identify the Old Notes to be withdrawn, including the certificate number(s) shown on the particular certificates evidencing such Old Notes (unless such Old Notes were tendered by book-entry transfer), the aggregate principal amount represented by such Old Notes and the name of the registered holder of such Old Notes, if different from that of the person who tendered such Old Notes, (3) be signed by the holder of such Old Notes in the same manner as the original signature on the Letter of Transmittal by which such Old Notes were tendered (including any required signature guarantees), or be accompanied by documents of transfer sufficient to have the trustee register the transfer of the Old Notes into the name of the person withdrawing such Old Notes, and (4) specify the name in which any such Old Notes are to be registered, if different from that of the registered holder. If the Old Notes were tendered pursuant to the procedures for book-entry transfer set forth in "The Exchange Offer--Procedures for Tendering" in the Prospectus, the notice of withdrawal must specify the name and number of the account at DTC to be credited with the withdrawn Old Notes and must otherwise comply with the procedures of DTC. If the Old Notes to be withdrawn have been delivered or otherwise identified to the Exchange Agent, a signed notice of withdrawal is effective immediately upon written or facsimile notice of such withdrawal even if physical release is not yet effected. Any permitted withdrawal of Old Notes may not be rescinded. Any Old Notes properly withdrawn will thereafter be deemed not validly tendered for purposes of the Exchange Offer. However, properly withdrawn Old Notes may be retendered by following one of the procedures described in the Prospectus under the caption "The Exchange Offer--Procedures for Tendering" at any time before the Expiration Date. All questions as to the validity, form and eligibility (including time of receipt) of such withdrawal notices will be determined by PETCO, in its sole discretion, which determination shall be final and binding on all parties. Neither PETCO, any affiliates of PETCO, the Exchange Agent or any other person shall be under any duty to give any notification of any defects or irregularities in any notice of withdrawal or incur any liability for failure to give any such notification. 4. PARTIAL TENDERS. Tenders of Old Notes pursuant to the Exchange Offer will be accepted only in principal amounts equal to $1,000 or integral multiples of $1,000. If less than the entire principal amount of any Old Notes evidenced by a submitted certificate is tendered, the tendering holder must fill in the principal amount tendered in the last column of the box entitled "Description of Tendered Old Notes" herein. The entire principal amount represented by the certificates for all Old Notes delivered to the Exchange Agent will be deemed to have been tendered unless otherwise indicated. If the entire principal amount of all Old Notes held by the holder is not tendered, new certificates for the principal amount of Old Notes not tendered and Exchange Notes issued in exchange for any Old Notes tendered and accepted will be sent (or, if tendered by book-entry transfer, returned by credit to the account at DTC designated herein) to the holder unless otherwise provided in the appropriate box on this Letter of Transmittal (see Instruction 6) as soon as practicable following the Expiration Date. 5. SIGNATURE ON LETTER OF TRANSMITTAL; BOND POWERS AND ENDORSEMENTS; GUARANTEE OF SIGNATURES. If this Letter of Transmittal is signed by the registered holder(s) of the Old Notes tendered hereby, the signature must correspond exactly with the name(s) as written on the face of the certificate(s) without alteration, enlargement or change whatsoever. If this Letter of Transmittal is signed by a participant in DTC whose name is shown as the owner of the Old Notes tendered hereby, the signature must correspond exactly with the name as it appears on the security position as the holder of the Old Notes. If any of the Old Notes tendered hereby are owned of record by two or more joint owners, all such owners must sign this Letter of Transmittal. <Page> If any tendered Old Notes are registered in different names on several certificates, it will be necessary to complete, sign and submit as many copies of this Letter of Transmittal and any necessary accompanying documents as there are different names in which certificates are held. If this Letter of Transmittal is signed by the holder, and the certificates for any principal amount of Old Notes not tendered are to be issued (or if any principal amount of Old Notes that is not accepted is to be reissued or returned) to or, if tendered by book-entry transfer, credited to the account at DTC of the registered holder, and Exchange Notes exchanged for Old Notes in connection with the Exchange Offer are to be issued to the order of the registered holder, then the registered holder need not endorse any certificates for tendered Old Notes nor provide a separate bond power. In any other case (including if this Letter of Transmittal is not signed by the registered holder), the registered holder must either properly endorse the certificates for Old Notes tendered or transmit a separate properly completed bond power with this Letter of Transmittal (in either case, executed exactly as the name(s) of the registered holder(s) appear(s) on such Old Notes, and, with respect to a participant in DTC whose name appears on a security position listing as the holder of Old Notes, exactly as the name(s) of the participant(s) appear(s) on such security position listing), with the signature on the endorsement or bond power guaranteed by a signature guarantor or an eligible guarantor institution, unless such certificates or bond powers are executed by an eligible guarantor institution, and must also be accompanied by such opinions of counsel, certifications and other information as PETCO or the trustee for the Old Notes may require in accordance with the restrictions on transfer applicable to the Old Notes. See Instruction 2. If this Letter of Transmittal or any certificates representing Old Notes or bond powers are signed by trustees, executors, administrators, guardians, attorneys-in-fact, officers of corporations or others acting in a fiduciary or representative capacity, such persons should so indicate when signing, and unless waived by PETCO, proper evidence satisfactory to the Exchange Agent, of their authority so to act must be submitted with this Letter of Transmittal. 6. SPECIAL ISSUANCE AND SPECIAL DELIVERY INSTRUCTIONS. Tendering holders should indicate in the applicable box or boxes the name and address to which Old Notes for principal amounts not tendered or Exchange Notes exchanged for Old Notes in connection with the Exchange Offer are to be issued or sent, if different from the name and address of the holder signing this Letter of Transmittal. In the case of issuance in a different name, the taxpayer-identification number of the person named must also be indicated. Holders tendering by book-entry transfer may request that Old Notes not exchanged be credited to such account maintained at DTC as such holder may designate. If no instructions are given, Old Notes not tendered will be returned to the registered holder of the Old Notes tendered. For holders of Old Notes tendered by book-entry transfer, Old Notes not tendered will be returned by crediting the account at DTC designated above. 7. TAXPAYER IDENTIFICATION NUMBER AND SUBSTITUTE FORM W-9. Federal income tax law generally requires that each tendering holder is required to provide the Exchange Agent with its correct taxpayer identification number, which, in the case of a holder who is an individual, is his or her social security number. If the Exchange Agent is not provided with the correct taxpayer identification number or an adequate basis for an exemption, the holder may be subject to backup withholding of a portion of any payment made with respect to the Old Notes and a $50 penalty imposed by the Internal Revenue Service. If withholding results in an over-payment of taxes, a refund may be obtained. Certain holders (including, among others, all corporations and certain foreign individuals) are not subject to these backup withholding and reporting requirements. See the enclosed "Guidelines for Certification of Taxpayer Identification Number on Substitute Form W-9" for additional instructions. To prevent backup withholding, each holder tendering Old Notes must provide such holder's correct taxpayer identification number by completing the Substitute Form W-9 set forth herein, certifying that the taxpayer identification number provided is correct (or that such holder is awaiting a taxpayer identification number), and that such holder is exempt from backup withholding either because (1) the holder has not been notified by the Internal Revenue Service that such holder is subject to backup withholding as a result of failure to report all interest or dividends or (2) the Internal Revenue Service has notified the holder that such holder is no longer subject to backup withholding. If the holder tendering Old Notes does not have a taxpayer identification number, such holder should consult the "Guidelines for Certification of Taxpayer Identification Number on Substitute Form W-9" for instructions on applying for a taxpayer identification number, check the box "Awaiting TIN" in Part 4 of the Substitute Form W-9, and sign and date the Substitute Form W-9 and the Certification of Awaiting Taxpayer Identification Number set forth herein. If the holder tendering Old Notes does not provide such holder's taxpayer identification number to the Exchange Agent within sixty (60) days, backup withholding will begin and continue until such holder furnishes such holder's taxpayer identification number to the Exchange Agent. NOTE: Checking the box "Awaiting TIN" on the form means that the holder tendering Old Notes has already applied for a taxpayer identification number or that such holder intends to apply for one in the near future. <Page> If the Old Notes are registered in more than one name or are not in the name of the actual owner, consult the "Guidelines for Certification of Taxpayer Identification Number on Substitute Form W-9" for information on which tax payer identification number to report. Exempt holders tendering Old Notes (including, among others, all corporations and certain foreign individuals) are not subject to these backup withholding and reporting requirements. To prevent possible erroneous backup withholding, an exempt holder tendering Old Notes must enter its correct taxpayer identification number in Part 1 of the Substitute Form W-9, write "Exempt" in Part 2 of such form and sign and date the form. See the "Guidelines for Certification of Taxpayer Identification Number on Substitute Form W-9" for additional instructions. In order for a nonresident alien or foreign entity to qualify as exempt, such person must submit a completed Form W-8, "Certificate of Foreign Status," signed under penalty of perjury attesting to such exempt status. Such form may be obtained from the Exchange Agent. PETCO reserves the right in its sole discretion to take whatever steps are necessary to comply with its obligation regarding backup withholding. 8. TRANSFER TAXES. PETCO will pay all transfer taxes, if any, required to be paid by PETCO in connection with the exchange of the Old Notes for the Exchange Notes. However, if Exchange Notes, or Old Notes for principal amounts not tendered or accepted for exchange, are to be delivered to, or are to be issued in the name of, any person other than the registered holder of the Old Notes tendered, or if a transfer tax is imposed for any reason other than the exchange of the Old Notes in connection with the Exchange Offer, then the amount of any transfer tax (whether imposed on the registered holder or any other persons) will be payable by the tendering holder. If satisfactory evidence of payment of the transfer taxes or exemption therefrom is not submitted with the Letter of Transmittal, the amount of such transfer taxes will be billed directly to the tendering holder. 9. MUTILATED, LOST, STOLEN OR DESTROYED OLD NOTES. If any certificate representing Old Notes has been mutilated, lost, stolen or destroyed, the holder should promptly contact the Exchange Agent at the address set forth on the cover of this Letter of Transmittal. The holder will then be instructed as to the steps that must be taken in order to replace the certificate. This Letter of Transmittal and related documents cannot be processed until the procedures for replacing mutilated, lost, stolen or destroyed certificates have been followed. 10. IRREGULARITIES. All questions as to the validity, form, eligibility, time of receipt, acceptance and withdrawal of any tenders of Old Notes pursuant to the procedures described in the Prospectus and the form and validity of all documents will be determined by PETCO, in its sole discretion, which determination shall be final and binding on all parties. PETCO reserves the absolute right to reject any or all tenders of any Old Notes determined by it not to be in proper form or the acceptance of which may, in the opinion of PETCO's counsel, be unlawful. PETCO also reserves the right to waive or amend any of the conditions of the Exchange Offer or to waive any defect or irregularity in the tender of any particular Old Notes, whether or not similar defects or irregularities are waived in the case of other tenders. PETCO's interpretations of the terms and conditions of the Exchange Offer (including, without limitation, the instructions in this Letter of Transmittal) shall be final and binding. No alternative, conditional or contingent tenders will be accepted. Unless waived, any irregularities in connection with tenders must be cured within such time as PETCO shall determine. Each tendering holder, by execution of this Letter of Transmittal, or a copy thereof, waives any right to receive any notice of the acceptance of such tender. Tenders of Old Notes shall not be deemed to have been made until such irregularities have been cured or waived. Any Old Notes received by the Exchange Agent that are not properly tendered and as to which the irregularities have not been cured or waived will be returned by the Exchange Agent to the tendering holders, unless such holders have otherwise provided herein, promptly following the Expiration Date. None of PETCO, any of its affiliates, the Exchange Agent or any other person will be under any duty to give notification of any defects or irregularities in such tenders or will incur any liability to holders for failure to give such notification. 11. REQUESTS FOR ASSISTANCE OR ADDITIONAL COPIES. Questions relating to the procedure for tendering, as well as requests for assistance or additional copies of the Prospectus, this Letter of Transmittal and the notice of guaranteed delivery may be directed to the Exchange Agent at the address and telephone number set forth on the cover of this Letter of Transmittal. Holders may also contact their broker, dealer, commercial bank, trust company or other nominee for assistance concerning the Exchange Offer.
