Contains ingredients in quantities sufficient to provide the estimated nutrient requirements for all stages of the life of a dog or cat, as the case may be, which have been established by a recognized authority on animal nutrition, such as the Committee on Animal Nutrition of the National Research Council of the National Academy of Science* or, *To the extent that the product's ingredients provide nutrients in amounts which substantially deviate from those nutrient requirements estimated by such a recognized authority on animal nutrition, or in the event that no estimation has been made by a recognized authority on animal nutrition of the requirements of animals for one or more stages of said animals' lives, the product's represented capabilities in this regard must have been demonstrated by adequate testing. 2. Contains a combination of ingredients which when fed to a normal animal as the only source of nourishment will provide satisfactorily for fertility of females, gestation and lactation, normal growth from weaning to maturity without supplementary feeding, and will maintain the normal weight of an adult animal whether working or at rest and has had its capabilities in this regard demonstrated by adequate testing. m. Labels for products which are compounded for or which are suitable for only a limited purpose (i.e., a product designed for the feeding of puppies) may contain representations that said pet food product or recommended feeding thereof, is or meets the requisites of a complete, perfect, scientific or balanced ration for dogs or cats only: 1. In conjunction with a statement of the limited purpose for which the product is intended or suitable (as, for example, in the statement 'a complete food for puppies'). Such representations and such required qualification therefor shall be juxtaposed on the same panel and in the same size, style and color print; and 2. Such qualified representations may appear on pet food labels only if: a. The pet food contains ingredients in quantities sufficient to satisfy the estimated nutrient requirements established by a recognized authority on animal nutrition, such as the Committee on Animal Nutrition of the National Research Council of the National Academy of Sciences for such limited or qualified purpose; or b. The pet food product contains a combination of ingredients which when fed for such limited purpose will satisfy the nutrient requirements for such limited purpose and has had its capabilities in this regard demonstrated by adequate testing. n. Except as specified by regulation PF 3(a), the name of any ingredient which appears on the label other than in the product name shall not be given undue emphasis so as to create the impression that such an ingredient is present in the product in a larger amount than is the fact, and if the name of more than one such ingredient are shown, they shall appear in the order of their respective predominance by weight in the product. Regulation PF3. Brand and Product Names. a. No flavor designation shall be used on a pet food label unless the designated flavor is detectable by a recognized test method, or is one the presence of which provides a characteristic distinguishable by the pet. Any flavor designation on a pet food label must either conform to the name of its source as shown in the ingredient statement or the ingredient statement shall show the source of the flavor. The word flavor shall be printed in the same size type and with an equal degree of conspicuousness as the ingredient term(s) from which the flavor designation is derived. Distributors of pet food employing such flavor designation or claims on the labels of the product distributed by them shall, upon request, supply verification of the designated or claimed flavor to the appropriate control official. b. The designation "100%" or "All" or words of similar connotation shall not be used in the brand or product name of a pet food if it contains more than one ingredient.

The term "meat" and "meat byproducts" shall be qualified to designate the animal from which the meat and meat-by-products are derived unless the meat and meat-by-products are from cattle, swine, sheep, and goats. For example, "horsemeat" and "horsemeat-by-products". d. The name of the pet food shall not be derived from one or more ingredients of a mixture to the exclusion of other ingredients and shall not be one representing any components of a mixture of a pet food product unless all components or ingredients are included in the name except as specified by Regulation PF 3(a), (e), or (f); provided that the name of an ingredient or combination of ingredients may be used as a part of the product name if: 1. The ingredient or combination of ingredients is present in sufficient quantity to impart a distinctive characteristic to the product or is present in amounts which have a material bearing upon the price of the product or upon acceptance of the product by the purchaser thereof; or 2. It does not constitute a representation that the ingredient or combination of ingredients is present to the exclusion of other ingredients; or 3. It is not otherwise false or misleading. e. When an ingredient or a combination of ingredients derived from animals, poultry, or fish constitutes 95% or more of the total weight of all ingredients of a pet food mixture, the name or names of such ingredient(s) may form a part of the product name of the pet food: Provided, that where more than one ingredient is part of such product name, then all such ingredient names shall be in the same size, style, and color print. f. When an ingredient or a combination of ingredients derived from animals, poultry or fish constitutes at least 25% but less than 95% of the total weight of all ingredients of a pet food mixture the name or names of such ingredient or ingredients may form a part of the product name of the pet food only if the product name also includes a primary descriptive term such as "meat- balls" or "fishcakes" so that the product name describes the contents of the product in accordance with an established law, custom or usage or so that the product name is not misleading. All such ingredient names and primary descriptive term shall be g. Contractions or coined names referring to ingredients shall be used in the brand name of a pet food unless it is in compliance with regulations PF 3 (a), (d), (e), or (f). Regulation PF4. Expression of Guarantees. a. The sliding scale method of expressing a guaranteed analysis (for example, "protein 15-18%") is prohibited. b. Pursuant to section 5(a)3 of the Rhode Island Commercial Feed Law, the label of a pet food which is formulated as and represented to be a mineral additive supplement, shall include in the guaranteed analysis the maximum and minimum percentages of calcium, the minimum percentage of phosphorus and the maximum and minimum percentages of salt. The minimum content of all other essential nutrient elements recognized by NRC from sources declared in the ingredient statement shall be expressed as the element and in units of measurement established by a recognized authority of animal nutrition. Such as the National Research Council. c. Pursuant to section 5(a)3 of the Rhode Island Commercial Feed Law, the label of pet food which is formulated as and represented to be a vitamin supplement, shall include a guarantee of the minimum content of each vitamin declared in the ingredient statement. Such guarantees shall be stated in units of measurements established by a recognized authority on animal nutrition such as the National Research Council. d. The vitamin potency of pet food products distributed in containers smaller than 1 lb. may be guaranteed in approved units per ounce. e. If the label of a pet food does not represent the pet food to be either a vitamin or a mineral supplement, but does not include a table of comparison of a typical analysis of the vitamin, mineral, or nutrient content of the pet food with levels recommended by a recognized animal nutrition authority, such comparison maybe stated in the units of measurement used by the recognized authority on animal nutrition such as the National Research Council. The statement in a table of comparison of the vitamin, mineral, or nutrient content shall constitute a guarantee, but need not be repeated in the guaranteed analysis. Such table of comparison may appear on the label separate and apart from the guaranteed analysis. Regulation PF5. Ingredients. a. The maximum moisture in all pet foods shall be guaranteed and shall not exceed 78.00% or the natural moisture content of the constituent ingredients of the product, whichever is greater.

Each ingredient of the pet food shall be listed in the ingredient statement, and names of all ingredients in the ingredient statement must be shown in letters or type of the same size. The failure to list the ingredients of a pet food in descending order by their predominance by weight in non-quantitative terms may be misleading. Any ingredient for which the Association of American Feed Control has established a name and definition shall be identified by the name so established. Any ingredient for which no name and definition has been so established shall be identified by the common or usual name of the ingredient. Brand or trade names shall not be used in the ingredient statement. c. The term "dehydrated" may precede the name of any ingredient in the ingredient list that has been artificially dried. d. No reference to quality or grade of an ingredient shall appear in the ingredient statement of a pet food. e. A reference to the quality, nature, form, or other attribute of an ingredient shall not be made unless such designation is accurate and unless the ingredient imparts a distinctive characteristic to the pet food because it possesses that attribute. Regulation PF6. Directions for Use. a. The label of a pet food product which is suitable only for intermittent or supplemental feeding or for some other limited purpose shall: 1. bear a clear and conspicuous disclosure to that effect; or 2. contain specific feeding directions which clearly state that the product should be used only in conjunction with other foods. Regulation PF7. Drugs and Pet Food Additives. a. An artificial color may be used in a pet food only if it has been shown to be harmless to pets. The permanent or provisional listing of an artificial color in the United States Food and Drug Regulations as safe for use, together with the conditions, limitations, and tolerances, if any, incorporated therein, shall be deemed to be satisfactory evidence that the color is, when used pursuant to such regulations, harmless to pets. b. Prior to approval of a registration application and/or approval of a label for pet food, which contains additives, (including drugs, other special purpose additives, or non-nutritive additives) the distributor may be required to submit evidence to prove the safety and efficacy of the pet food, when used according to directions furnished on the label. Satisfactory evidence of the safety and efficacy of a pet food may be: 1. When the pet food contains such additives, the use of which conforms to the requirements of the applicable regulation in the Code of Federal Regulations, Title 21, or which are "prior sanctioned" or "Generally Recognized as Safe" for use or 2. When the pet food itself is a drug as defined in section 3 (g) of the chapter and is generally recognized as safe and effective for label use or is marketed subject to an application approved by the Food and Drug Administration under Title 21, U.S.C. 360 (b). c. The medicated labeling format recommended by the Association of American Feed Control Officials shall be used to assure that adequate labeling is provided.
