Food for cats from 1 to 7 years old, living indoors. The highly digestible feed of Royal Canin Indoor 27 contributes to a significant weakening of the smell of cat stool as a result of a decrease in the release of hydrogen sulfide, fetid gas released from feces. Moderate energy content: helps to reduce body fat in cats due to a moderate calorie content and the addition of L-carnitine (50 mg / kg). Excretion of hair lumps: stimulates intestinal transit due to a combination of fermentable and non-fermentable fiber.
