AAFCO Statement on Cat Food Labels: What Complete and Balanced Means
Of everything on a cat food bag or can, one small block of text matters more than the front-of-pack claims. It is the nutritional adequacy statement, and it tells you whether the food can safely be the main diet. Learn to read it, and you can cut through a lot of marketing.
Who is AAFCO?
The Association of American Feed Control Officials is a nonprofit organization of state and federal regulators in the United States. It does not test or approve foods. Instead, it publishes nutrient profiles, which set minimum, and some maximum, levels of nutrients for dogs and cats, and model rules that many states adopt for pet food labeling. Other regions use different bodies, such as FEDIAF in Europe, with similar guidance. See how to read a cat food label.
Where to find the statement
It is usually on the back or side of the package, near the guaranteed analysis and ingredient list. It might read:
- "Brand Food is formulated to meet the nutritional levels established by the AAFCO Cat Food Nutrient Profiles for adult maintenance."
- "Animal feeding tests using AAFCO procedures substantiate that Brand Food provides complete and balanced nutrition for growth."
- "Brand Food provides complete and balanced nutrition for all life stages."
Two ways to substantiate
Formulation method. The manufacturer or a nutritionist formulates the recipe to meet the nutrient profile, and often confirms with lab analysis. It does not prove that cats absorb the nutrients, or that the food is palatable.
Feeding trial method. Cats eat the food as their sole diet for a set period, usually at least 26 weeks, with health measures such as weight, blood values and condition tracked. Passing is a stronger indicator that the food works in real cats. Not every good food has been through trials, as they are costly.
Neither method judges the quality of ingredients, or digestibility, or long-term outcomes.
Life stages
- Growth and reproduction, for kittens, and pregnant or nursing queens. See kitten feeding schedule.
- Adult maintenance, for healthy adults.
- All life stages, which meets the higher requirements of growth and reproduction. Suitable for adults, but may be richer in calories, so portions matter.
- Senior. There is no official AAFCO senior nutrient profile, so a food labeled senior is a marketing term. See best food for senior cats.
"Intermittent or supplemental feeding only"
Foods that carry this phrase are not complete. They include many treats, toppers, mixers and some wet foods designed to add variety. Do not feed them as the sole diet. If your cat eats only one of these foods, deficiencies will follow. Many freeze-dried toppers and "pâté stews" are of this kind. See freeze-dried cat food.
Therapeutic and prescription diets
Veterinary diets are formulated for specific conditions, such as kidney disease. They may say "use only as directed by your veterinarian". They are designed for medical use, and are not for healthy cats unless the vet agrees. See cat kidney disease stages.
What the statement does not tell you
- Ingredient quality, sourcing or freshness.
- Digestibility and bioavailability.
- Whether your individual cat will do well on it.
- How safe the manufacturing process is.
- Whether claims such as natural or premium are meaningful.
Other label items to read
Check the guaranteed analysis for protein, fat, fiber and moisture, and the ingredient list, which is by weight before cooking. Look for the manufacturer's contact details, and for calorie content, in kilocalories per can or cup. Contact the company if you want to know who formulates its foods, whether it employs a veterinary nutritionist and what quality control it uses. The World Small Animal Veterinary Association has a list of questions for owners.
Homemade and boutique foods
Many small brands, and most home recipes, do not have an adequacy statement at all. Without one, you cannot assume that the food is complete. See homemade cat food safety.
Checking with your vet
Your vet can help you interpret labels, and recommend diets that suit your cat. Bring the packaging to the appointment. See cat wellness exam: what to expect and cat food types explained.
Using the statement day to day
When you buy a new food, turn the package over and find the statement before anything else. If it says the food is complete and balanced for your cat's life stage, you can use it as a main diet. If it says intermittent or supplemental feeding only, treat it as an extra. Photograph the label so you can show your vet exactly what your cat eats. If you ever switch to a new brand, check the statement again, because different products from the same company can carry different claims.
When to see a vet
See a vet if your cat has changes in coat, weight, appetite or stool after a diet change. Use the US vet directory to find a clinic.
