My cat loves the taste!

[This review was collected as part of a promotion.] I was nervous when my cat was switched to this new food for health reasons. I was so happy he immediately ate it!! Whew!

All the cats loved it

[This review was collected as part of a promotion.] I was given a sample at the vet to see if one of my cats, Raffi would eat it instead of regular dry. Not only does he love it, but so do my other 2 cats. They love both the "A" version and the "S" version

Lucy's favorite!!!

[This review was collected as part of a promotion.] My kitty, Lucy, was diagnosed with renal failure earlier this year and started a Royal Canine diet. Lucy was a Valentine's Day gift from my husband in 2002. We call her our "little old lady cat" and love her very much! We tried all of the flavors in the Renal Support Line and Support A seems to be her favorite. Even though I know her diet now is even more important, the cost of the food is a concern.I have researched trying to find the best place to purchase it and if coupons are available, but continue to get it from her veterinarian as for now.

Royal Canin (A) Dry Cat Food

14-yr old male Pan was diagnosed with early renal & started on all the Royal Canin A dry cat food & a few tins of wet and yes, as I read others he's gained weight, not so bony, & I can't be happier he's going to live longer.

I love Royal Canin

I bought this for my cat Buddy who had stage 2 kidney disease. I took him to the vet for blood work 6 months later and his labs were normal. MY Buddy is back to his normal playful crazy self! I would recommend this diet absolutely!

Great to hear that Buddy is doing so well!

My senior, picky cat likes it

After over $1,000 to figure out what is wrong with my cat we have it to where she is now on this special food. She is gaining weight and seems to be doing much better on this food.
