Dry food · Adult Maintenance

Therapeutic (veterinary) diet. Whether this food is right for your cat's condition is your vet's call — not our score's. We rate every food on the same scale, this one included.

Furry PI's verdict

Hill's k/d Kidney Care + z/d Food Sensitivity is a therapeutic (veterinary) diet, so its nutrient profile deliberately differs from healthy-adult targets — that is why it grades the way it does on our general scale. Whether it suits your cat's condition is a decision for your vet, not for a score. If it has been prescribed, follow that advice; our analysis is only useful for understanding what is inside.

What's concerning

The ingredient list leads with grains — brown rice and rice protein concentrate — rather than animal protein.
Contains chicken liver flavor, a lower-quality ingredient.
A high carbohydrate load for an obligate carnivore — a cat's natural prey is almost carb-free.

What works

No artificial colours or preservatives on the ingredient list.

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.
