Wet 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

Blue Buffalo K+M 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

Contains unnamed "fish oil" — the species isn't specified.
A modest share of calories comes from protein.

What works

Chicken leads the ingredient list — the right start for an obligate carnivore.
As a wet food, it delivers the moisture cats rarely drink on their own.
Carbohydrate load stays close to what a cat would eat in nature.

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.
