Royal Canin Indoor 27 Dry Cat Food

Indoor living changes a cat's metabolism, activity and digestive needs. Royal Canin Indoor 27 addresses these differences with moderate fat content adapted for the lower energy expenditure of the indoor lifestyle.

L.I.P. proteins with very high digestibility reduce stool volume and odour, a critical benefit when the litter tray shares the living space. Psyllium husks and seeds at 0.5% help stimulate intestinal transit of ingested hair, reducing hairball formation through natural elimination.

The formula supports urinary health through balanced minerals, particularly important for indoor cats who may drink less. Available in 400 g, 2 kg, 4 kg and 10 kg bags.

• Stool odour reduction: A lack of exercise may lead to a slower intestinal transit and smelly stools. INDOOR 27® contains highly digestible protein (L.I.P.*) and helps reduce the quantity and odour of stools. *L.I.P.: protein selected for its very high digestibility

What makes Indoor 27 different from regular cat food?

Royal Canin Indoor 27 is specifically adapted for the lower activity, increased grooming, and shared-space living that define the indoor cat's lifestyle.

• Reduced calories
• Enhanced stool odour control
• Psyllium fibre for hairball reduction

Will this help with my cat's litter tray smell?

Yes. The L.I.P. proteins are selected for their very high digestibility, which means less undigested material reaches the colon for bacterial fermentation. This directly reduces both the quantity and odour of stools.

What does the "27" in Indoor 27 mean?

The number refers to the protein content at 27%, which is calibrated for the lower muscle maintenance demands of sedentary indoor cats compared to the 32% in Fit 32 for more active cats.

My cat goes outside occasionally. Should I use Fit 32 instead?

If your cat has regular outdoor access and moderate activity, Fit 32 provides a better energy match. Indoor 27 is specifically designed for cats who live entirely or almost entirely indoors.
