PETCO Receives Nasdaq Notice Regarding Audit Committee Composition

SAN DIEGO -- November 14, 2005 -- As recently announced by PETCO Animal Supplies, Inc. (Nasdaq: PETC), Arthur Laffer has resigned from PETCO's Board of Directors effective November 7, 2005. Because Dr. Laffer served on the Board's three-person Audit Committee, The Nasdaq Stock Market, Inc. has provided PETCO with an automatic notification, dated November 7, 2005, that its Marketplace Rule 4350 requires an audit committee to be composed of at least three independent directors. PETCO has a cure period under Nasdaq's rules which extends until the earlier of November 7, 2006 or PETCO's next annual stockholders' meeting.

PETCO's Board of Directors is currently considering the composition of its various committees and intends to appoint a third member to its Audit Committee well within the cure period. In this regard, the Board is currently composed of nine members, seven of whom are independent and thus eligible to serve on the Audit Committee under Nasdaq's rules. In addition, both of the Audit Committee's current members are designated as a financial expert, although Nasdaq rules require only one such member.

In the unlikely event that PETCO does not appoint a third member to the Board's Audit Committee within the required period, PETCO's stock is subject to delisting.
