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

Purina UR Urinary St/Ox 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 — corn protein meal and rice — rather than animal protein.
  • Contains phosphoric acid — 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

  • 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.
