Helps move hairballs formed while grooming through a cat's digestive system with an optimal blend of fibers

Controlled calorie content adapted for an indoor cat’s leisurely lifestyle and big appetite, helping them maintain a healthy weight

Highly digestible proteins increase the digestibility of nutrients while decreasing stool amounts (and litter box odors)

Promotes oral health with its crunchy kibble texture and added essential minerals that slow the formation of tartar

Indoor cats live a life of leisure, spending most of their days napping, grooming, and grazing. All that leisure time requires precise nutrition to ensure adult cats don't put on extra weight, regurgitate hairballs, and leave some less-than-desirable stool odors in their litter box.

Royal Canin Indoor dry cat food is targeted nutrition made for those lovably lazy housecats to live a long, magnificent life. Moderate calorie levels help maintain a healthy weight. Optimal fibers control hairballs. Highly digestible proteins decrease the amount of waste in their litter box and its less-than-desirable smell. And because dental tartar affects a number of adult cats, the unique dry cat kibble encourages chewing to help reduce dental and tartar buildup. Top off their bowl with your cat’s favorite Royal Canin Adult Instinctive wet cat food for a texture that pleases even the finickiest eater.

No words for how impressed I am!

I tried this because I was told that the food I was using could be the cause of the unbearable stink in the litter box. It was at the level that I was surprised the neighbors weren't donning gas masks and making evacuation plans. Switching to this food got that problem under control in a matter of days, and despite my attempt to gradually switch to the new food, my cats made it clear they prefer this one, by eating all the bits of the new food, and leaving all their old kibble that it was mixed with in the bottom of the bowl while claiming their dishes were empty.

Great benefits!

I was told my 15 lb cat could lose some weight. I tried at least three weight loss formulas and could not get my cat to switch. One of them even gave him hairballs which he had never had before. The best I could do was try an indoor formula with lower calories. He ate this instantly without a formal change process. He had his vet checkup this past week and has lost 3/4 lb in 5 months. I’d say it’s working. The Royal canin indoor has a nice larger kibble size which seems to be keeping his teeth in good shape and offers good digestive benefits without specifically being a hairball control or digestive formula. My cat has medium length fur. This food meets our needs.

Cat's Love it!

I got a sample of this a while ago and my two cats both love it. I've been feeding it to them ever since. I do mix it with their prescription food and both disappear every day.

My cats love this food!

I am very picky what I feed my cats and always have been. My two kitties are three years old and I have been feeding Royal Canin Indoor 27 since I adopted them from my vets. I had to send Diana, my 18 year old cat to the Rainbow Bridge and was going to stop with her as my cats do live a long time...before Diana I had Duster who lived to 20 and Adame' who was a few months shy of 23! But now I have Indie and Aidan. I have tried other dry foods, but they turn their noses up. I don't buy dry cat food at the market. My guys just love this food. The pieces are larger and I feel are great for cleaning their teeth. I am very happy with Indoor 27 and I know other people that Feed it to their cats too! Yes it is a bit pricey, but these are my babies and they deserve the best! Plus their coats are shiny and healthy looking!
