How to Decipher Cat Food Product Labels

What Information Do Cat Food Labels Contain?

Cat food labels provide limited information regarding the nutritional value of the package contents. It is important for customers to know what can and cannot be determined from the label, and what information is particularly important. Major components of a pet food label include:

  • Guaranteed Analysis
  • Company/Customer Service Information/Satisfaction
  • Ingredient Panel
  • Manufacturing Code, Expiration, or "Best Used By" Information
  • Feeding Instructions
  • AAFCO Statement of Nutritional Adequacy
 

Guaranteed Analysis

Values in the guaranteed analysis are expressed as either minimum or maximum. A maximum guarantee (% max) means at most this specific amount of the nutrient is included in the formula. A minimum guarantee (% min) means at least this specific amount of the nutrient is included in the formula. The following four nutrients must be included on all pet food labels:

  • Crude Protein (% min)
  • Crude Fiber (% max)
  • Crude Fat (% max)
  • Moisture (% max)

For example, a cat food with a 25% minimum crude protein guarantee should contain at least 25% protein, but could contain much more. The only way to determine the actual amount is by laboratory analysis.

Other information may be guaranteed on cat food products, such as magnesium (% max), taurine (% min), ash (% max), and linoleic acid (% min).

  • The guaranteed analysis is an important tool when beginning to compare cat food formulas, but it doesn't provide meaningful nutritional information. Using information on the energy content and nutrient density of a food is the only way to properly compare cat foods. This information is available from the manufacturer.
 

Feeding Guidelines

Cat food labels must include recommended feeding amounts, expressed as the daily quantity to feed the cat. Good, detailed feeding instructions help eliminate the need for confusing calculations that may result in improper feeding.

Due to the critical nutrient requirements for growth, kitten products should provide specific feeding rates related to age and weight.

  • Feeding instructions are average recommendations. Sometimes, less or more food may be required to maintain proper condition of an individual cat.
 

AAFCO Statement of Nutritional Adequacy

AAFCO nutritional adequacy statements are required on all pet foods. Products may either be formulated or tested according to AAFCO procedures and recommendations.

Due to the critical nutrient requirements for growth, kitten products should provide specific feeding rates related to age and weight.

  • A "formulated" statement means the product has been manufactured according to AAFCO nutritional guidelines, but not actually fed to cats prior to sale.
  • A "tested" statement indicates the product has been formulated, then fed to cats prior to sale to ensure it meets important criteria related to growth, maintenance, and/or reproduction.

Veterinary-exclusive products include statements such as, "This product is intended for intermittent feeding only" and "Use only as directed by your veterinarian."
