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 Adult 27 is designed to meet the specific nutritional needs of your indoor adult cat. 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 4.8 out of 5 by 98 reviewers.
Rated 5 out of 5 by It's a fixer I have 5 cats, 1 momma and her 4 babies which is 4 females and 1 male. The male has a bladder crystal problem and he is on a special Royal Canin for that but wants to eat the reg. and it's ok for him to eat this. I then have 2 of the kitties who have a sensitive GI tract and I've been through a million kinds of food for this and almost 10 years later this is the perfect food for them to eat. Problem solved. If I could give this a million stars...I would. Thanks Royal Canin!!! You gave me a product to relieve stress. My babies are back to being active like happy kitties. Complete joy :-) January 16, 2017
Rated 5 out of 5 by Finally a food my 5 cats love after the 1st bag In the last year I've tried all the popular foods looking for a food that my 5 cats still enjoy after that initial 1st bag is finished. I sold royal canin when I worked for a vet for 20 years and always knew it was a great food but this one so far I'm so thrilled with that my cats still love it after 2nd bag. My 5 have never eaten every piece ( even the stray pieces that escape their bowls) They eat every morsel and drag us out of bed in am begging for it...this is the one finally I can keep all 5 on even with the difference from kitten to diabetic 12 year my oldest....thrilled with this food.

Rated 5 out of 5 by Transition going well. Vet advised to put my two kitties on this particular food. They seem to be adapting to it quite well. January 9, 2017
Rated 5 out of 5 by Cats love it Needed to try a new food for my fluffy cats. They love this brand, so hoping it helps them lose a little extra pounds. January 5, 2017
Rated 5 out of 5 by Vet recommended and my cats love it! Had my previous cats on Royal Canin food and they loved it as much as Alex and Dante do. :) January 2, 2017
Rated 5 out of 5 by My Himalayans love this food. A++++++ very satisfied with this product. My cats love the taste and seem really happy. December 19, 2016
Rated 5 out of 5 by A Real Hit! My cats absolutely love Royal Canin, and I feed over a dozen cats between my indoor kitties and my strays. I've had twenty plus years of experience as a cat owner (okay, servant or actually, slave!) and it's highly unusual to find a single food that all my felines like, but I can honestly say that each and every cat is enthusiastic about eating this food. I'd go so far as to say that they like it almost as much as canned food, which I no longer give them. In addition, I feel good about using this product due to its high quality. My "kids" all have a lot of energy and their coats are super soft and shiny. When I started feeding my stray, Henry, this food, his coat improved greatly. Before he found me, it did not look like any human had cared for him previously, as he looked quite scraggly, but now when I pet him, his coat feels 100% better, and I can tell by his behavior that he also feels better. If you have cats that like to snub what you put in their bowl, do yourself a favor and try this food! August 3, 2012
Rated 2 out of 5 by bad choice My animals don't believe your reviews. They don't like it. December 17, 2016
