Works and they love it!

My older SF with LUTD has been on this for about 5 months now, and she loves it! We are having less accidents in the house. Her behavior has changed too, used to be aggressive and now as loving as can be. The research that goes behind the food is fantastic as well! Thank you Royal Canin!

Enjoyed by all

I have 4 cats that all really enjoy this food. I know that I don't have to worry about urinary tract infections with my cats on this food. I have had cats with urinary tract infections before, but not since they have changed to this particular food. I also give them the canned/wet food version, too. They love it!

No UTIs for 2+ years!

I have 10 kitties, 4 of them males, some of them semi-feral. We were averaging a UTI every two months, which is a nightmare when dealing with cats that won't be picked up, let alone crated for a ride to the veterinarian. This food, with the added Calm, has kept them UTI free and ever so slightly chill, a bonus in a house with this many cats. It's expensive, sure, but less than the cost of all of those UTI visits.

Kept my cat healthy thank you royal canin

My poor kitty Michael Jordan gets chronic UTIs which can be life threatening in male cats. This food has kept him UTI free for years. Thank you Royal Canin

My kitties love their crunchies

I have two cats but only one is on a urinary calm diet. I feed them both the same thing and they both love to have crunchy food along with wet food. They seem to like it.
