We don't grade this one

This is a prescription veterinary diet. These are therapeutic foods, formulated to manage specific medical conditions and available only through a veterinarian. insPAWction scores everyday retail products — not medical diets. Grading one would imply a judgment about whether it's right for treating a condition, and that judgment belongs to the veterinarian who knows your pet.

You can still see its ingredients below, but there's no Product Score. Please consult your veterinarian.

Read this before you trust the number

This application is intended for educational purposes only. Scores are generated using publicly available product information and are not veterinary advice. We are not veterinarians. Always consult your veterinarian regarding medical decisions.

A high score does not mean a product is right for your pet, and a low score does not mean it is dangerous. An individual animal can react to an ingredient that scores well here, and a product with a mediocre score may be exactly what your vet recommends.

The score reads ingredients one at a time. It cannot account for how ingredients interact with each other, with other products you use, or with your pet's medications and conditions. Two ingredients that are each fine on their own may not be fine together. A score is a starting point for questions, not a substitute for professional judgment.
