How to Read a Cat Food Label (Without Getting Misled)

Cats are obligate carnivores, which changes what matters on the label. The front of the bag is marketing; the back has the four blocks that actually tell you whether this food fits your cat.

1. The Guaranteed Analysis

Same format as dog food: minimums for protein/fat, maximums for fiber/moisture. For cats, protein minimums matter more — adult cats typically need more dietary protein than dogs on a dry-matter basis.

To compare a wet and a dry food, convert both to a dry-matter basis: subtract moisture from 100, then divide each nutrient by that number.

2. The Ingredients List

Ingredients are listed by weight before cooking. “Fresh salmon” as ingredient #1 is ~70% water; a “salmon meal” listed third can contribute more actual protein once cooked. Prefer:

• Named animal protein sources first and second.
• Named fats (“chicken fat”, “salmon oil”).
• A short, recognizable list.

Watch for taurine specifically. In most commercial cat foods, taurine is either in the ingredient list or guaranteed separately. Taurine deficiency causes serious heart and eye problems in cats.

3. The Calorie Content

The feeding math block. Usually listed per cup (dry) or per can (wet). Plug the kcal-per-cup into our cat food calculator.

For wet food, convert calories per can to calories per day by dividing target kcal/day by kcal per can. Most indoor neutered adult cats need fewer calories than the bag implies — start at the low-activity estimate and adjust.

4. The AAFCO Statement

Look for:

• “meets AAFCO nutrient profiles for adult maintenance” — meets minimum requirements.
• “animal feeding tests using AAFCO procedures…” — a feeding trial was conducted.
• “for all life stages” — meets growth and reproduction requirements too (appropriate for kittens).

A cat food without an AAFCO statement is not necessarily bad, but it’s not making a regulatory claim of completeness.

Red flags specific to cats

• No taurine listed.
• High carbohydrate load with minimal animal protein.
• Marketed as “grain-free” without explaining protein source.

Putting it together

Use the Guaranteed Analysis and ingredient list to judge quality. Use the calorie content to feed correctly — our cat food calculator does the math. If itching or digestive issues match ingredient patterns, try the allergy checker with the same photo of the ingredient panel.
