worked well!

I am skeptical of the quality of foods like this but the vet recommended it for one of my cat’s stones. I had her on it for a few weeks and her stones dissolved, saving her from having a surgery that’s a few thousand dollars. I’ll feed my cats this forever.

Urinary diet

My male cat needed surgery for his stones and then a revision one month later. Through analysis it was determined the stones were strictly diet related. He now needs to be on a prescription diet continuously. We have 3 other cats and it is to difficult to keep them separated. So the wet foods we are still working on but the dry food was a hit at the first bowl. Will definitely continue to purchase.

Love Chewey service!

My old cat, Puff, is predisposed to urinary blockage and must live out his life on prescription food only. Chewy provides it, faithfully, a new case every two weeks. Don't know what I would do without Chewy.

Saved lifes

This food saved my cats life. I spent over $3,000 because she became sick fast. Even though she's an outside cat, she's my baby. I have her and my 4 other barn yard cats ok this food as well as my 2 inside cats. My babies are healthy and alive.

Bad quality control

My cats normally love this food but the most recent bag we got they won’t touch. It also smells off - kind of chemically or like expired crackers. It’s not past the expiration date on the bag, but is clearly a bad batch. My cats have been on this food since March 2020, but this is the second time this has happened - the last time was October 2021. Both times, Chewy has been great about replacing the defective bag quickly and at no cost, but Purina definitely needs to step up their quality control. You can tell immediately when you open the bag by the smell that something isn’t right. If you got a bag this month and your cats won’t touch it and it smells weird, definitely call Chewy.

Prescription food

My kitty was getting frequent UTI's and the vet prescribed this food. He loves it and he is so much better! It took about two weeks to really make a difference but now he is acting like he feels better and not peeing outside the box.

Only wish I had ordered this sooner

After hesitating on trying this dry food, I finally ordered it for my cat who is on prescription urinary foods. I am thrilled that he loves this food more than the better known brand prescription urinary foods. Purina did tell me that cats seem to really prefer this food to the others and they were right. Absolutely worth the money to see my cat gobble this up.

Literally like kitty crack

So, a few years ago my first kitty, Hope, got a UTI, so the vet prescribed this and she's been on it ever since. Since then, we've moved in with a roommate that has two cats and also adopted a brother for her, Kyo. Idk what it is about this food, but I have to literally pry my roommate's cats away, and after we got Kyo it was the only food he would eat after getting over his anxiety. I don't mind that the other cats eat it but it's expensive lol. But kudos to Purina for making a cat food that not only makes the kitties happy but keeps me having peace of mind that the kitties won't have a UTI again.

Happy cats

Thank you Chewy. This dry food is great for keeping my two guys, Ferrari and Sylvyie hydrated. Perfect for keeping them from developing urinary tract stones. Thank you again and for Sylvyie’s birthday card too!
