Best Cat Food: What to Compare
How to choose a cat food the way the Cornell Feline Health Center describes - the AAFCO statement, life stage, meat first, wet or dry - and five indoor, urinary and everyday foods compared on what their makers publish, with a rough dry-matter comparison of wet and dry.
AI illustration This is a reading guide to published feline nutrition advice and to what makers state on their own pages. A cat with a health problem may need a diet your vet chooses. A cat that strains in the litter box and passes little or no urine may have a urinary blockage, which the Cornell Feline Health Center calls an absolute emergency.
The short answer: the “best” cat food is a complete and balanced one that your cat will eat. The Cornell Feline Health Center gives a short checklist:
- The AAFCO statement. Foods that carry it are considered nutritionally complete and balanced.
- Your cat’s life stage. The statement should name the stage the food is complete for: kitten, adult maintenance or all life stages.
- Meat first. Meat, meat byproducts or seafood should be among the first few ingredients.
After that, Cornell says, choosing between canned and dry can come down to what your cat prefers.
What the Label Tells You
Cats are obligate carnivores: they rely on nutrients found only in animal products, and need high protein, moderate fat and minimal carbohydrate, Cornell explains. The label shows three things worth reading:
- The nutritional adequacy statement. It says either that the food is “formulated to meet” the AAFCO nutrient profiles, or that “animal feeding tests using AAFCO procedures” back it up, and for which life stage.
- The ingredient list, in order of weight.
- The guaranteed analysis: minimum protein and fat, maximum fiber and moisture, as sold.
Wet or dry? Cornell gives dry food 6 to 10% water and canned food at least 75%, which makes canned food a good source of water. Because the guaranteed analysis includes the water, a wet food’s protein figure looks small next to a dry food’s. To compare them, divide by the share that isn’t water. The column in the table below does this roughly, from each label’s minimum protein and maximum moisture.

How we put this together. Five widely sold foods from three makers: three dry and two wet, covering indoor, urinary and everyday feeding. We compared them on what each maker states on its own product page, checked on 26 October 2026. We have not fed them, and a label cannot tell you how a particular cat will do. The rough dry-matter figure is our arithmetic, not the makers’: minimum protein divided by the share of the food that isn’t water. Hill’s publishes its dry-matter figure directly, so we used it as given. There are no prices here: the Amazon links search for the exact food, and we may earn a commission if you buy through them. Makers change recipes, so check the bag or can you buy.
About “Indoor” and “Urinary” Labels
Indoor formulas are each maker’s own recipe, and two of the three dry foods above also name hairballs. The label tells you what the maker aimed for. What matters is the same checklist as above, and keeping your cat at a healthy weight.
Urinary health formulas need a closer look. Cornell notes that many makers market diets for “urinary health”. These may make a urethral blockage less likely in cats with feline idiopathic cystitis. But Cornell says there is no evidence that they reduce how often lower urinary tract problems happen at all (Cornell). Cornell also lists who is most often affected: middle-aged, overweight cats that get little exercise, use an indoor litter box and drink less water. Stress, such as a multi-cat home or a change in routine, plays a part too. A cat with urinary signs needs a diagnosis first. Stones, for example, differ: struvite stones can sometimes be dissolved with a prescription diet, but calcium oxalate stones cannot.
Treats and Extras
- Treats: Cornell’s rule of thumb is no more than 10 to 15% of a cat’s daily calories.
- Supplements: Cornell says they can be harmful and should never be given without your vet’s approval.
- Avoid: raw meat, a potential vehicle for toxoplasmosis; canned fish made for people; and milk, as many cats are lactose-intolerant.
- Water: clean, fresh water at all times.
