What It Is and How It Works
Royal Canin designs formulas for specific lifestyles, breeds and life stages. Indoor Adult has moderate calories for less active cats. It also includes a fiber blend that the company says helps move hair through the gut and reduce stool odor, which matters to many indoor cat owners with litter boxes in living spaces.
Royal Canin, part of Mars Petcare, employs veterinary nutritionists and conducts research. It’s one of the brands many vets recommend for that reason. The company also makes prescription veterinary diets.
Indoor cats can still gain weight on any food if portions are too large. Measure meals and check your cat’s body condition every few weeks. See obesity in cats and how much to feed your cat.

How to Judge a Cat Food Label
Every cat food label in the United States should carry a nutritional adequacy statement, often called the AAFCO statement. It tells you whether the food is “complete and balanced” and for which life stage, such as adult maintenance, growth or all life stages.
Other questions many vets suggest asking a pet food company include:
| Question | Why it matters |
|---|---|
| Do you employ a full-time board-certified veterinary nutritionist or PhD animal nutritionist? | Expertise in formulating diets |
| Are foods formulated to meet standards or tested in feeding trials? | Feeding trials test how cats actually do on the food |
| What quality control steps do you use? | Consistency and safety |
| Do you do research and publish it? | Investment in nutrition science |
These questions come from widely shared veterinary guidance on choosing pet foods. See pet nutrition: choosing the right cat food.
Things to Consider Before Buying
- Check the AAFCO statement for adult maintenance.
- Measure portions rather than free-feeding.
- Consider adding wet food for moisture.
- Switch gradually over a week or more.
- Ask your vet if your cat has health conditions.
