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

  • For indoor cats over 10 years of age
  • Powerful antioxidants including vitamin E to help combat the impact of free radicals responsible for cell aging
  • Softer kibble that helps protect sensitive gums and teeth
  • Improved digestibility may contribute to smaller and less foul smelling feces

Rated 4.8 out of 5 by 43 reviewers.
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
Rated 5 out of 5 by Great product My 15 year old cat loves this new food, she's eating better due to the fact that the product is small and breaks apart so chewing is easier. She took to it immediately and the other younger cats sat around wanting some. Nope, only for the old girl, they got royal canin hairball formula and love it also. September 28, 2016
Rated 5 out of 5 by My cats love this! My older cats were getting very stinky until I switched to this cat food! Now their litter box isn't stinking up the house! And my cats are very happy with it. September 25, 2016
Rated 5 out of 5 by Tasty and good for them This is my splurge product...usually my cats prefer the cheaper brands (like I usually prefer junk food!). September 7, 2016
Rated 5 out of 5 by Excellent product! We've been using this product for several months and we're thrilled when we rec'd the mailer advertising this website, We saved over $10.00 per bag before the introductory offer coupon. We are loyal customers now. The product arrived with an expiration date of over a year out also. Very happy! August 27, 2016
Rated 5 out of 5 by Stress-free transition! My two furbabies transitioned to this food with the first serving. That has always been an issue when introducing a new diet. August 14, 2016
Rated 5 out of 5 by My cat likes this food! It hasn't been long enough for me to notice any changes in my cat, except he likes this food. I'm hopeful that it does help with his constant shedding. July 23, 2016
Rated 5 out of 5 by Best dry cat food I have used. When I was given this cat, they also told me the kind of food to keep her on. I did this for some time but she would get such from time to time on it plus she kept loosing weight. I have used Royal Canin for most all my cats before so decided to go back to it. I am so glad I did. My cat is gaining back some lost weight and is not sick, so far. Very happy with Royal Canin and will stick with it from now on. They have a special kind for almost all cat breeds and needs. July 7, 2016
