Indoor adult cats like yours tend to get less exercise than outdoor cats, that’s why a balanced and complete diet containing beneficial nutrients is important for optimal health. ROYAL CANIN® Indoor 27 contains a highly digestible protein (L.I.P.) that’s specifically selected for its very high digestibility. This protein also helps to reduce the quantity of your cat’s stool, as well as reducing the smelly stool odour that occurs when cats have a lower intestinal transit due to a lack of exercise.
