Product Reviews
Royal Canin ® Feline Health Nutrition™ Indoor Adult dry cat food is rated 4.9 out of 5 by 109.
Rated 5 out of 5 by from Quality product that my cats love! Royal Canin was recommended to me by both my Vet and my breeder when my at that time, only pure bred Tonkinese turned out to be allergic to fish. I have been using Royal Canin ever since! I was a tad hesitance when the new formula came out as that was how Yum-Yum's fish allergy was discovered with when trying another premium brand, but I still trusted in the science & research behind Royal Canin. They have yet to disappoint my felines! Frankly, my cats love the dry food and have turned their picky noses up at other edible offerings and jump over to their dining area, with plates of Royal Canin instead of people food!

Rated 5 out of 5 by from Happy Cat Happy Life!! I started buying this 5 years ago due to the rescue cats we were taking in and not knowing what they had been eating also wanting them to be healthy. From the crinkle of the bag to the love purring afterwards we love, love this product and will continue use it for all 5 of our striped babies.

Rated 5 out of 5 by from Excellent dry food I've been feeding this dry food to my two kitties for almost a year (since they became grown ups!). I was so pleased to discover this Royal Canin diet. I particularly like the dental control properties and odor control (I can smell the difference with my little boy cat ;) if you get my drift). What's best of all is that my cats love this diet, and they have been able to maintain an ideal body condition from it (my vet agrees they're perfect weight!). Thank you Royal Canin for making great, high quality products that I feel good about feeding to my kitties!!!

Rated 5 out of 5 by from Healthy, Happy Cats I have been feeding Royal Canin to my cats since they were kittens and I would never dream of changing brands. Not only do my cats LOVE this dry food but I notice that my cats have less hairballs and are leaner than previous indoor cats I had, was feeding them a different brand. Any indoor cat owner knows that hairballs can be a constant struggle and Royal Canin Indoor Adult 27 has significantly reduced the number of hairballs that my cats have (and that I have to clean-up).

Rated 5 out of 5 by from Our cat loves it We have a almost 2 year old Maine Coon mix that has only eaten Royal Canin food. When we got the cat Shish he was eating the kitten formula which we continued buying until we switched to this formula. He likes the food and has been a very healthy easy to maintain cat. Our vet mentioned how nice Shish's fur was and was glad to hear he is on a good diet. I would recommend this food for sure, it's expensive but worth.

Rated 5 out of 5 by from My kittys love it I have multiple cats and they all come running when they hear the food container open. They love it. They are fast eaters but no one regurgitates so it is easy to digest. Being indoor cats this diet has really helped to maintain healthy weights on all of them. I had been feeding them Royal Canin Kitten when they were kittens and when it came time to change to an adult diet I had gone to another trusted quality brand. Within 2 months of eating that diet one of my cats developed urinary issues. When I compared the labels I discovered that the new food did not contain the proper ingredients to maintain urinary health but the Royal Canin did. This particular kitty did not need to be on a lifelong urinary prescription diet but did need to be maintained on a diet that did maintain urinary health. Once I switched to the Indoor Adult 27 they have all been very healthy and no further urinary issues. I thank you and my kitties thank you Royal Canin.

Rated 5 out of 5 by from This is one of the best dry foods I was looking for a high quality dry food for my cats. This is better than most of the prescription/high end foods the vet would have. My cats are 9 and 3 and have healthy eyes, coat and energy. This is a huge part due to this food. Thank you. I have recommended this to a few friends and they have bought it too. You do pay a bit more but it's worth it. I would be nice to have some coupons now and then.

Rated 5 out of 5 by from Only dry food I will feed my furbaby My boy loves this it has all the vitamins he needs as a indoor cat and I love the " smell control feature " when I change his litter. Everyone comments on how beautiful and shiny his coat is as well.
