Whether you love cats for their beauty, their elegance or their agility, a cat is above all a companion. That’s why lifestyle, sensitivities and age are all crucial considerations when it comes to choosing the right nutrition. Royal Canin Indoor Mature 27 is designed to meet the specific nutritional needs of indoor mature cats. Cats living exclusively indoors have a more sedentary lifestyle, lower energy requirements and a higher risk of obesity. The lifestyle of the indoor cat, sheltered from temperature variations and changes in day length, disrupts the natural seasonal cycle of fur growth. This means indoor cats shed almost continuously, and paired with long grooming sessions, have an increased risk of hairball formation.

Key Benefits

  • Royal Canin supports the health of your cat by providing him with precise nutrition based on a true understanding of his specific needs and over 40 years of science and observation. Cats living exclusively indoors have a more sedentary lifestyle, lower energy requirements and a higher risk of obesity
  • A lack of exercise may lead to a slower intestinal transit which can result in smelly stools. This product is formulated with a highly digestible protein (L.I.P.*), an appropriate fiber content and specific nutrients to promote good digestion and help reduce the quantity and odor of stools.
  • A moderate fat content adapted to the lower activity of indoor cats to help maintain healthy weight.
  • A combination of different types of fibers that encourages intestinal transit and helps facilitate the elimination of the hair your cat swallows every day.
  • This product provides 100% complete and balanced diet. Formulated with the optimal balance between proteins, fats and carbohydrates to support long-term palatability and work as the perfect nutritional complement.

Rated 4.7 out of 5 by 50 reviewers.
Rated 1 out of 5 by Was hoping for this to be it! I've bought Acana, Royal Canin regular indoor 27 and now this. With the others, they at least gave it a try once, but my cats won't even touch this. Still searching. January 3, 2017
Rated 5 out of 5 by My cats new favorite My older cat is very finicky and he only eats dry food. Many of his favorites have been discontinued and he will not eat the same food two days in a row. He was very excited with this product from the first bowl I poured and he actually will eat this two days in a row. January 2, 2017
Rated 5 out of 5 by 16 year old granny kitty loves it Great food for and older picky feline. She likes the smaller pieces and the formula has helped with her digestive issues December 15, 2016
Rated 1 out of 5 by Bad smell My cats loved it, but it has a bad, sour, nasty odor that could be smelled though out the whole house. I bought 3 bags so it wasn't a bad bag. The smell was so bad I went back to Science Diet. November 29, 2016
Rated 5 out of 5 by Great food for older kitties with dental problems!! Our 10yr old kitty was having problems with chewing his hard food. Our vet recommended this food and he is back to eating a regular diet and loves the food! I would highly recommend this food November 27, 2016
Rated 5 out of 5 by Well Rounded Flavor I found this set of morsels to be crunchy yet with a hint of moisture. The aroma filled the nose from an acceptable distance. As an older customer I appreciated the ease of digestion. This defiantly allows for less time in the litter box. My recommendation....Will eat again Sincerely Boomer PS: It save my owner 50% over Petsmart November 17, 2016
Rated 5 out of 5 by Great for aging cats My oldest cat is 13. He has some severe dental issues, and eats mainly wet food, but I like to leave dry out during the times I am not home for him to snack on. This is exceptionally easy for him to eat and he has had no increase in vomiting or other tummy troubles since starting it! November 7, 2016
Rated 5 out of 5 by My girls love it Been using Royal Canin for years for all of my feline pets. I started because my older boys were having trouble chewing and with this product it was easier for them to chew. Both my boys are gone now, but my girls still love the product and get excited when I open a new bag. October 7, 2016
