At Man’s side for millenia, the dog has adapted, but he has behavioral and nutritional requirements of his own. Knowing them and respecting them will guarantee his well-being and his health.

The cat’s feline nature is always a matter of fascination. He adapts with apparent ease to daily life, and yet he has behavioral and nutritional requirements of his own. Knowing them and respecting them will guarantee his well-being and his health.

Because of its composition, a Royal Canin Health Nutrition food provides all essential nutrients measured out with utmost precision in order to contribute every day and on a long-term basis to the well-being and health of every animal, according to his age, his size, his physiological condition and his breed.

Innovation for the sake of dogs and cats’ health. For over 40 years, Royal Canin has worked with breeder partners and veterinary nutritionists to go ever further into innovation and precision to enable us to formulate nutritional solutions which perfectly meet dogs and cats’ real needs.

Reduction of stool odours

Reduction of stool odours

*Highly digestible, Indoor 27 significantly reduces stool odour by reducing emanations of hydrogen sulphide by an average of 60% compared with that from stools resulting from reference foods for indoor cats; this gas, which emanates from faecal matter, is known to be particularly smelly.

(Royal Canin study, 2006)
