Indoor 27 is a complete pet food for cats living indoors aged between 1 & 10 years. Living indoors reduces the cat's activity level, so the calorie intake must be reduced to try & maintain their ideal weight. The lack of exercise leads to a slower intestinal transit. This phenomenon can cause intestinal disorders & result in soft smelly faeces left in the litter tray. Indoor 27 helps maintain your cat's ideal weight. It has a moderate calorie supply & the addition of L-carnitine to help mobilise fat stores.A combination of non-fermentable fibres & beet pulp help stimulate intestinal transit & can assist in the elimination of ingested hairs. Indoor 27 significantly reduces stool odour by reducing emissions of hydrogen sulphide (which is particularly smelly) by an average of 60%.
