Furry PI's verdict

The label tells a weaker story than the front of the pack suggests for Hill's Adult Perfect Digestion. Grains crowd the top of the ingredient list. To be fair, includes genuinely beneficial ingredients such as salmon and chicken fat. On balance, most cats are better served by stronger options — the app can suggest better-graded foods of the same type.

What's concerning

Salmon leads, but grains — brown rice, corn protein meal and whole grain oats — dominate the rest of the list.
Contains menadione sodium bisulfite complex — an ingredient our database flags as genuinely problematic for cats.
A high carbohydrate load for an obligate carnivore — a cat's natural prey is almost carb-free.

What works

Includes genuinely beneficial ingredients such as salmon and chicken fat.

The grade is only the cover of the case file. The free app shows the full 100-point breakdown, every flagged ingredient, and better-graded alternatives for your cat.
