Lack of exercise in indoor cats may lead to a slower intestinal transit, resulting in smelly stools. Royal Canin Indoor 27+ Cat Food is a complete meal with Highly Digestible Protein( LIP*) and adequate fibre content for keeping the gut healthy and reducing the quantity and odour of stools. The food also helps stimulate intestinal transit for good passage of food and prevents the formation of hairballs in cats. The moderate calorie content of the Royal Canin Indoor Cat+ diet supports the less active lifestyle of indoor cats and helps the felines reach optimum weight.
