Tips
- Protein is High (48% dry matter) on our label-based comparison range. This is generally more aligned with cats' higher protein needs than lower-protein recipes, assuming the food is complete for the cat's life stage.
- Fat is High (17% dry matter) on our label-based comparison range. It can raise calorie density, so watch body condition and seek vet input for cats with pancreatitis or digestive disease.

Is Royal Canin Adult British Shorthair grain-free?
Yes — Royal Canin Adult British Shorthair is grain-free according to its printed ingredient list: no gluten grains (like wheat) and no gluten-free grains (like rice or corn) appear in the recipe.

What are the main protein sources in Royal Canin Adult British Shorthair?
The animal proteins in Royal Canin Adult British Shorthair include Meat And Animal Derivatives, Fish And Fish Derivatives, but some appear under generic terms such as “meat” or “poultry” rather than by species. Generic labeling lowers the recipe’s protein-clarity score in Moesonson’s analysis, because it stops you verifying the exact protein source — a drawback for pets with specific protein allergies.
