A diet for indoor and rather sedentary adult cats. Highly digestible, Indoor significantly reduces stool odour by reducing production of hydrogen sulphide; this gas, which emanates from faecal matter, is known to be particularly smelly. [Royal Canin Study, 2006.]. LIP*: Protein (90% digestibility) selected for its high level of assimilation. Moderate energy content contributes to reducing fat storage due to a moderate calorie supply and the addition of L-carnitine (50 mg/kg ). Hairball regulation stimulates intestinal transit and the elimination of ingested hairs thanks to a combination of non-fermentable and fermentable fibres.
