At Royal Canin, we believe the secret to providing cats and dogs with the best nutrition lies not in any passing fad, but in well-researched scientific fact. That’s why we always use a purely scientific approach to create diets designed to cater to the specific needs of pets of all shapes, sizes, ages, lifestyles and breeds.

From the time they’re born until they’re well into their golden years, dogs’ nutritional needs are constantly changing, and we believe their food should, too. That’s why we offer a full line of products designed for dogs at every life stage. 

From the time they’re kittens until they’re mature, cats’ nutritional needs are constantly changing, and we believe their food should, too. Your cat’s health matters, and that’s why we offer a full line of nutrition designed for every life stage. 

ROYAL CANIN® PROFESSIONAL products are specifically formulated to meet the needs of the breeding kennel and cattery.  Our innovative science-based solutions are the result of our 40-year collaboration and partnership with breeders across the globe.

As a company that was founded by a veterinarian, Royal Canin is committed to investing in the veterinary community.

Royal Canin is a global leader in pet health nutrition. In an industry that continues to adapt to popular trends in cat and dog food, our mission will remain the same; to constantly bring, through Health Nutrition and shared knowledge, the most precise nutritional solution for cats’ and dogs’ health nutrition needs, by building on constantly deepened scientific knowledge and Royal Canin’s roots in the feline and canine professional networks.

INDOOR Light 40™

For indoor cats prone to obesity from 1 to 10 years

Cats living exclusively indoors have a more sedentary lifestyle, lower energy requirements and a higher risk of obesity. The lifestyle of the indoor cat, sheltered from temperature variations and changes in day length, disrupts the natural seasonal cycle of fur growth. This means indoor cats shed almost continuously, paired with long grooming sessions, have an increased risk of hairball formation.
