With so many cat food options out there focused on ingredients, how do you know what's best? Royal Canin knows there's a science to it—researching each pet's nutritional needs to create a diet with the precise combination of nutrients needed to live a magnificent life. 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. With nearly 50 years of scientific research and observation, Royal Canin continues to deliver targeted nutrition to feed every pet's magnificence. Not satisfied? Then neither are we.
