Rated 4.8 out of 5 by 118 reviewers.
Rated 5 out of 5 by First time customer Recommend by a friend who loves the site and products. My cat requires prescription dry food and I ordered it here. They had to send a request to my vet for the rx which I thought I would have to wait for. My order shipped and delivered a few days later with no further action from me. They also give the option to take a picture of the rx label. Extremely fast and auto shipping is convenient for necessary reorder. Very pleased so far! January 18, 2017

Rated 5 out of 5 by Great for preventing urinary tract infections This product has been used by our cat for 13 years to alleviate urinary tract issues. It has worked very successfully. December 24, 2016
Rated 4 out of 5 by Good product and fast service. My vet had recommended a different product when we realized my cat had a longstanding UTI. After a week of her vomiting that food, we switched to this Purina product. It took a few days for her to warm up to it, but she is keeping it down and now eats it with gusto! She is a happier and healthier feline, now. December 10, 2016
Rated 5 out of 5 by Great Product! My 16 year old cat has urinary issues. My vet recommended this dry formula for her. It is very palpable and my kitty loves it! She gobbles it right up and never has any issues. November 26, 2016
Rated 5 out of 5 by Great prescription diet I had an extremely hard time finding a new prescription food after my cat had an urtheral obstruction. I went through 3 different types of food, mind you my cat loves all food so for him to not eat them they must not be great. And the dogs love it too! November 12, 2016
