PETCO Receives Notice of Potential Delisting From NASDAQ Due to Late Filing of Form 10-K

PETCO Receives Notice of Potential Delisting From NASDAQ Due to
Late Filing of Form 10-K 


SAN DIEGO, May 23  /PRNewswire-FirstCall/ -- PETCO Animal Supplies, Inc.
(NASDAQ:PETCE) today announced that on May 19, 2005, the Company received
notice from The Nasdaq Stock Market, Inc. Listing Qualifications Staff that the
Company's securities are subject to potential delisting as of May 31, 2005 due
to the Company's failure to file its annual report on Form 10-K for the fiscal
year ended January 29, 2005 (the "2004 Form 10-K") on a timely basis.

On April 29, 2005, the Company had previously announced a delay in the filing
of its 2004 Form 10-K pending the completion of its internal review, first
announced on April 15, 2005, into errors involving the under-accrual of
expenses in the Company's Distribution Operation.  The Company expects to file
its 2004 Form 10-K within the next couple of weeks.

Because of this delay, the Company is not in compliance with NASDAQ Marketplace
Rule 4310(c)(14), which requires the timely filing with NASDAQ of all reports
and other documents filed or required to be filed with the SEC. Also, as a
result of the filing delinquency, NASDAQ changed the Company's trading symbol
for its securities from "PETC" to "PETCE" at the opening of business today, May
23, 2005.

The Company plans to request a hearing before a NASDAQ Listing Qualifications
Panel to review the Staff determination and request continued listing on NASDAQ
until the Company files its 2004 Form 10-K.  In its notification letter, the
NASDAQ staff informed the Company that this request will result in a
postponement of the delisting pending the Panel's decision. However, the
Company can provide no assurance that the Panel will grant its request for
continued listing.
