Ladies and Gentlemen:

At your request, we have examined the Registration Statement on Form S-3 (the “Registration Statement”), filed on date hereof with the Securities and Exchange Commission (the “Commission”) relating to the offering from time to time, pursuant to Rule 415 of the General Rules and Regulations of the Commission promulgated under the Securities Act of 1933 (the “Securities Act”):

(i) by Central Garden & Pet Company, a Delaware corporation (the “Company”), of the following securities in an indeterminate amount, in U.S. dollars or in one or more foreign currencies: (a) senior and subordinated debt securities of the Company (collectively, the “Debt Securities”); (b) guarantees of the Debt Securities (the “Guarantees”) by various Company subsidiaries (the “Subsidiary Guarantors”); (c) common stock of the Company, par value $0.01 per share (the “Common Stock”), including Common Stock that may be issued upon conversion of the Debt Securities or the Warrants (as defined below); (d) Class A common stock, par value $0.01 per share (the “Class A Common Stock”), including Class A Common Stock that may be issued upon conversion of the Debt Securities or the Warrants; (e) preferred stock of the Company, par value $0.01 per share (the “Preferred Stock”), including preferred stock that may be issued upon conversion of the Debt Securities or the Warrants; and (f) warrants to purchase Debt Securities, Common Stock, Class A Common Stock and Preferred Stock (collectively, the “Warrants”); and

(ii) by certain selling securityholders of the Company to be named in a prospectus supplement of shares of Class A Common Stock and Common Stock.

The offering of the Debt Securities and related Guarantees, the Common Stock, the Class A Common Stock, the Preferred Stock and the Warrants (collectively, the “Securities”) will be as set forth in the prospectus contained in the Registration Statement (the “Prospectus”), as supplemented by one or more supplements to the Prospectus. The Debt Securities may be issued pursuant to an indenture between the Company and a financial institution to be identified therein as trustee in the forms included as Exhibits 4.6 and 4.7 to the Registration Statement, as such indentures may be supplemented from time to time (each, an “Indenture”).

This opinion is being furnished in accordance with the requirements of Item 601(b)(5) of Regulation S-K under the Securities Act, and no opinion is expressed herein as to any matter pertaining to the contents of the Registration Statement or Prospectus, other than as to the enforceability of the Debt Securities, the Guarantees and the Warrants, and the validity of the Common Stock, the Class A Common Stock and the Preferred Stock.

We have examined the originals, or copies identified to our satisfaction, of such corporate records of the Company, certificates of public officials, officers of the Company, the Subsidiary Guarantors, and other persons, and such other documents, agreements and instruments as we have deemed relevant and necessary for the basis of our opinions hereinafter expressed. In such examination, we have assumed the following: (a) the authenticity of original documents and the genuineness of all signatures; (b) the conformity to the originals of all documents submitted to us as copies; and (c) the truth, accuracy, and completeness of the information, representations, and warranties contained in the records, documents, instruments, and certificates we have reviewed.

Based on and subject to the foregoing, and assuming that: (i) the Registration Statement and any amendments thereto (including post-effective amendments) will have become effective and comply with all applicable laws; (ii) the Registration Statement will be effective and will comply with all applicable laws at the time the Securities are offered or issued as contemplated by the Registration Statement; (iii) a Prospectus Supplement will have been prepared and filed with the Commission describing the Securities offered thereby and will comply with all applicable laws; (iv) all Securities will be issued and sold in compliance with applicable federal and state securities laws and in the manner stated in the Registration Statement and the appropriate Prospectus Supplement; (v) a definitive purchase, underwriting, or similar agreement with respect to any Securities offered or issued will have been duly authorized and validly executed and delivered by the Company and the other parties thereto; and (vi) any Securities issuable upon conversion, exchange, or exercise of any Security being offered or issued will be duly authorized, created, and, if appropriate, reserved for issuance upon such conversion, exchange, or exercise, we are of opinion that:

1. The Debt Securities (including any Debt Securities duly issued upon the exchange or conversion of any Debt Securities that are exchangeable or convertible into another series of Debt Securities) and the Guarantees will constitute legally valid and binding

We hereby consent to the reference to us under the heading “Validity of the Securities” in the Prospectus and to the filing of this opinion as Exhibit 5.1 to the Registration Statement.
