Furry PI's verdict
Our investigation turned up real problems with Royal Canin Siamese Adult. A lower-quality protein leads and grains crowd the list. To be fair, no artificial colours or preservatives on the ingredient list. On balance, most cats are better served by stronger options — the app can suggest better-graded foods of the same type.
What's concerning
- Chicken by-product meal — a lower-quality ingredient — leads, and grains — wheat gluten, corn and wheat — dominate the rest of the list.
- A high carbohydrate load for an obligate carnivore — a cat's natural prey is almost carb-free.
- A modest share of calories comes from protein.
What works
- No artificial colours or preservatives on the ingredient list.
