Customer Ratings & Reviews

Rated 4.3 out of 5 by 44 reviewers.
Rated 3 out of 5 by No flavors! The food is dense, so a can goes a longer way than the canned food one buys in supermarkets. The food only comes in one flavor (which is unknown), making it necessary to mix feeding it with other low magnesium canned food for variety. December 22, 2013
Rated 4 out of 5 by Good prescription food for cat with crystals This canned prescription food is a little higher in protein and less carbs than some of the others. My cats eat it with no problem and have kept the crystals away! December 4, 2014
Rated 5 out of 5 by Reliable product, well loved by my cats Feline UR is an excellent product that had been recommended by my vet when my cat had urinary crystals. I also use the dry UR food, but since my cat also takes thyroid medicine, the canned UR helps to administer his drug. My cat never again had a problem with urinary crystals - 6 years ago. October 17, 2014
Rated 5 out of 5 by best urinary food says my cat He's tried both flavors of Hill's KD Renal, but once he tried this, he refuses to touch the other food! Having already had surgery for a stone, I am pleased he is happy now. October 11, 2014
Rated 5 out of 5 by this is a quality food. This has helped our boy dramatically. I love that it comes in the 5.5 oz can. September 9, 2014
Rated 5 out of 5 by Actually smells good, not like some cat food. My cat is approximately 2 years old and the vet has him on a urinary special diet. I had tried several brands, which he really wouldn't eat. He really likes the Purina UR, but now I have to watch his weight (he is a rescued indoor kitty now). I use both the wet and dry UR. December 4, 2013
Rated 1 out of 5 by cat won't eat My cats won't eat it at all. I end up throwing it away everyday. Very upset that I can't get them to eat the wet food. They eat the dry July 12, 2015
Rated 3 out of 5 by So far so good. I was able to order UR online without a veterinarian prescription. It is much less expensive than buying it from the Vet directly. My cat does use the litter box more often. Waiting to see if the crystals and inflammation are reduced. April 14, 2014
