immediately following PETCO's initial public offering on February&nbsp;22, 2002, and allowing for issuances of Common Stock by PETCO from time to time, the number of shares of Common Stock available
for issuance under the Incentive Plan may increase to an aggregate of approximately 4,435,100 shares over the next three fiscal years, excluding the 564,900 shares reserved for issuance upon the

duty, except (1)&nbsp;for any breach of the director's duty of loyalty to the corporation or its stockholders, (2)&nbsp;for acts or omissions not in good faith or which involve intentional

or redemptions, or (4)&nbsp;for any transaction from which a director derived an improper personal benefit. </FONT></P>


<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Reference

threatened, pending or completed legal action, suit or proceeding, whether civil, criminal, administrative or investigative, other than an action by or in the right of such corporation, by reason of
the fact that such person was an officer, director, employee or agent of such corporation or is or was serving at the request of such corporation as a director, officer, employee or agent of another
corporation or enterprise. The indemnity may include expenses (including attorneys' fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by such person in connection
with such action, suit or proceeding, provided such officer, director, employee or agent acted in good faith and in a manner he reasonably believed to be in, or not opposed to, the corporation's best
interest and, for criminal proceedings, had no reasonable cause to believe that his conduct was unlawful. A Delaware corporation may indemnify any officer or director in an action by or in the right
of the corporation under the same conditions, except that no indemnification is permitted without judicial approval if the officer or director is adjudged to be liable to the corporation. Where an
officer or director is successful on the merits or otherwise in the defense of any action referred to above, the corporation must indemnify him against the expenses that such officer or director
actually and reasonably incurred. </FONT></P>

Section&nbsp;13(a) or Section&nbsp;15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan's annual report pursuant to Section&nbsp;15(d) of the Exchange Act)
that is incorporated by reference in this Registration Statement shall be deemed to be a new Registration Statement relating to the securities offered therein, and the offering of such securities at
that time shall be deemed to be the initial </FONT><FONT SIZE=2><I>bona fide</I></FONT><FONT SIZE=2> offering thereof. </FONT></P>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)&nbsp;&nbsp;Insofar
as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of PETCO pursuant to existing
provisions, or otherwise, PETCO has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act and is,
therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by PETCO of expenses incurred or paid by a director, officer or controlling
person of PETCO in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, PETCO will,
unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against
public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue. </FONT></P>

Pursuant
to Rule 416(a) under the Securities Act of 1933, as amended, this Registration Statement shall also cover any additional shares of common stock, par value $0.001 per
share (the "Common Stock"), that become issuable under either of the plans being registered pursuant to this Registration Statement or options granted thereunder by reason of any stock dividend, stock
split, recapitalization or other similar transaction effected without receipt of consideration that increases the number of outstanding shares of Common Stock.
(2)
Represents
(a) 836,080 shares of Common Stock reserved for issuance upon the exercise of outstanding options granted under the 1994 Stock Option and Restricted Stock Plan for
Executive and Key Employees of PETCO Animal Supplies, Inc., as amended and restated as of October 2, 2000 (the "1994 Plan"), and (b) 1,724,076 shares of Common Stock issued by
PETCO pursuant to the exercise of options granted under the 1994 Plan.
(3)
Estimated
solely for purposes of calculating the registration fee under Section 457(h) of the Securities Act. The price of $0.60 per share represents the weighted average
exercise price of the options granted under the 1994 Plan.
(4)
Represents
60,836 shares of Common Stock available for future grants under the 1994 Plan.
(5)
Estimated
solely for purposes of calculating the registration fee pursuant to Rules 457(h) and 457(c) under the Securities Act, based on the average of the high and low prices
for the Common Stock as reported on the Nasdaq National Market on March 4, 2002.
(6)
Represents
564,900 shares of Common Stock reserved for issuance upon the exercise of outstanding options granted under the 2002 Incentive Award Plan of PETCO Animal
Supplies, Inc. (the "Incentive Plan").
(7)
Estimated
solely for purposes of calculating the registration fee under Section 457(h) of the Securities Act. The price of $19.00 per share represents the exercise price of the
outstanding options granted under the Incentive Plan.
(8)
A
maximum of 1,170,756 shares of Common Stock was initially reserved for issuance under the Incentive Plan, including (a) 1,115,006 shares of Common Stock issuable upon the
exercise of options or other awards granted under the Incentive Plan (collectively, "Awards") and (b) 55,750 shares of Common Stock issuable upon the exercise of options to be automatically
granted to PETCO's independent directors ("Director Options"). The maximum number of shares of Common Stock issuable under the Incentive Plan will automatically increase on March 1 of each year
during the term of the Incentive Plan, commencing on March 1, 2003, by (x) an amount equal to 2.0% of the total number of issued and outstanding shares of Common Stock outstanding as of
the last day of the fiscal year immediately preceding such March 1 with respect to Awards and (y) an amount equal to 0.1% of the total number of issued and outstanding shares of Common
Stock outstanding as of the last day of the fiscal year immediately preceding such March 1 with respect to Director Options. Based on the number of shares of Common Stock outstanding
immediately following PETCO's initial public offering on February 22, 2002, and allowing for issuances of Common Stock by PETCO from time to time, the number of shares of Common Stock available
for issuance under the Incentive Plan may increase to an aggregate of approximately 4,435,100 shares over the next three fiscal years, excluding the 564,900 shares reserved for issuance upon the
exercise of outstanding options granted under the Incentive Plan.

PETCO is incorporated under the laws of the State of Delaware. Reference is made to Section 102(b)(7) of the Delaware General Corporation Law, or DGCL,
which enables a corporation in its original certificate of incorporation or an amendment thereto to eliminate or limit the personal liability of a director for violations of the director's fiduciary
duty, except (1) for any breach of the director's duty of loyalty to the corporation or its stockholders, (2) for acts or omissions not in good faith or which involve intentional
misconduct or a knowing violation of law, (3) pursuant to Section 174 of the DGCL, which provides for liability of directors for unlawful payments of dividends of unlawful stock purchase
or redemptions, or (4) for any transaction from which a director derived an improper personal benefit.
Reference
is also made to Section 145 of the DGCL, which provides that a corporation may indemnify any person, including an officer or director, who is, or is threatened to be
made, party to any
threatened, pending or completed legal action, suit or proceeding, whether civil, criminal, administrative or investigative, other than an action by or in the right of such corporation, by reason of
the fact that such person was an officer, director, employee or agent of such corporation or is or was serving at the request of such corporation as a director, officer, employee or agent of another
corporation or enterprise. The indemnity may include expenses (including attorneys' fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by such person in connection
with such action, suit or proceeding, provided such officer, director, employee or agent acted in good faith and in a manner he reasonably believed to be in, or not opposed to, the corporation's best
interest and, for criminal proceedings, had no reasonable cause to believe that his conduct was unlawful. A Delaware corporation may indemnify any officer or director in an action by or in the right
of the corporation under the same conditions, except that no indemnification is permitted without judicial approval if the officer or director is adjudged to be liable to the corporation. Where an
officer or director is successful on the merits or otherwise in the defense of any action referred to above, the corporation must indemnify him against the expenses that such officer or director
actually and reasonably incurred.
PETCO's
bylaws currently provide for indemnification of the officers and directors to the full extent permitted by applicable law.
Item 7.    Exemption from Registration Claimed.
Not Applicable.
Item 8.    Exhibits.
A list of exhibits filed with this Registration Statement is set forth in the Exhibit Index and is incorporated herein by reference.
Item 9.    Undertakings.
(a)  The
undersigned registrant hereby undertakes:
(1)  To
file, during any period in which offers or sales are being made, a post-effective amendment to this Registration Statement:
(i)
To
include any prospectus required by Section 10(a)(3) of the Securities Act;
(ii)
To
reflect in the prospectus any facts or events arising after the effective date of this Registration Statement (or the most recent
post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in this Registration Statement. Notwithstanding the
foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high
end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Securities and Exchange Commission pursuant to Rule 424(b) if, in the aggregate, the
changes in volume and price represent no more than 20 percent change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective
Registration Statement; and
(iii)
To
include any material information with respect to the plan of distribution not previously disclosed in this Registration Statement or any material
change to such information in this Registration Statement;
provided, however
, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if the information required to be included in a
post-effective amendment by those paragraphs is contained in periodic reports filed with or furnished to the Securities and Exchange Commission by PETCO pursuant to Section 13 or
Section 15(d) of the Exchange Act that are incorporated by reference in this Registration Statement.
(2)  That,
for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new Registration
Statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial
bona fide
offering thereof.
(3)  To
remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the
offering.
(b)  The
undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of PETCO's annual report pursuant to
Section 13(a) or Section 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan's annual report pursuant to Section 15(d) of the Exchange Act)
that is incorporated by reference in this Registration Statement shall be deemed to be a new Registration Statement relating to the securities offered therein, and the offering of such securities at
that time shall be deemed to be the initial
bona fide
offering thereof.
(c)  Insofar
as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of PETCO pursuant to existing
provisions, or otherwise, PETCO has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act and is,
therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by PETCO of expenses incurred or paid by a director, officer or controlling
person of PETCO in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, PETCO will,
unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against
public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.
SIGNATURES
Pursuant to the requirements of the Securities Act, PETCO certifies that it has reasonable grounds to believe that it meets all of the requirements for filing on
Form S-8 and has duly caused this Registration Statement to be signed on its behalf by the undersigned, thereunto duly authorized, in the City of San Diego, State of California, on
March 11, 2002.
