Rated 5 out of 5 by This product has worked for Cooper Cooper has cysts on his kidneys and had a blockage a few years ago and needed to be rushed in for emergency services. Since he's been on Purina UR St/Ox he's been doing good. November 18, 2015
Rated 5 out of 5 by Good food We have to feed our two cats this as one of them had urinary issues as a 2 year old so I don't really know if this qualifies as a review? However having been recommended to use Chewys by our new vet here in Glenview, IL ( Glenview Animal Hospital) I couldn't be happier with the easy ordering, price and fats delivery! December 7, 2015
Rated 5 out of 5 by Marley Likes it Marley really likes this dry food better then other prescription urinary foods he has tried and no crystals so far. May 7, 2016
Rated 5 out of 5 by Purina UR Our cat suffered from frequent urinary tract infections. Our vet recommended Purina UR and Miss Kitty has been uti free for at least 6 years. I highly recommend this product with veterinarian approval. February 17, 2014
Rated 5 out of 5 by Finally a food that works! I had to put my cat on prescription urinary food after he had a urinary blockage (hospitalization, catheter, you know the drill). It has been quite a struggle finding the right formula that agrees with him. I have tried all the other urinary formulas and they all gave him diarrhea. This was my last option. Purina is the only one that kept his stool formed. He has had normal urination too. June 20, 2014
Rated 5 out of 5 by My cat likes it! This is the only prescription dry food that my cat will eat. We tried all the others and he preferred the Purina. May 22, 2016
Rated 5 out of 5 by Cat loves this stuff My cat recently had to get costly surgery for urinary obstruction. Thankfully he's ok and normal. My great vet recommended this food for prevention and he loves this stuff more than his Fancy Feast. May 9, 2016
Rated 5 out of 5 by This food has been very effective. Since my 14 year old male cat began eating this food, all of his UTIs have ended!!! and he loves this food. What a blessing for both of us! May 12, 2016
