Pets can be sensitive to sudden changes in their diets. For this reason, it is extremely important to follow a gradual transition plan to best support your pet's health and product effectiveness. It is recommended to follow at least a 7-day transition plan before exclusively feeding your pet a new food. Cats will often refuse mixed diets, so we recommend adding the new food to a separate bowl from the old food. Start by mixing 75% of your pet's current diet with 25% of the new diet on Day 1 and Day 2. On Day 3 and Day 4, mix 50% of the current diet with 50% of the new diet. On Day 5 and Day 6, mix 25% of the current diet with 75% of the new diet. On Day 7, you can feed your pet the new food exclusively. Ask your Veterinarian about the best way to transition your pet to a new food.
Transition Day | Current Diet | New Diet |
---|---|---|
Days 1-2 | 75% | 25% |
Days 3-4 | 50% | 50% |
Days 5-6 | 25% | 75% |
Day 7 | 0% | 100% |

My poor older male cat has developed urine crystals, which require special food to break them down. Vet has to prescribe, so it's very expensive. Which would not be a problem, if Max liked and ate it! I know it's very important he eats this, but after 2 bites, he refuses. I have begun slowly introducing it into his regular kibble, but still no success. Wish it could be made tastier, or at least offer variety of flavours.
I got a new bag about a month ago and my cat was throwing it up anytime he ate it. I thought it was a bad batch so got a replacement through chewy. Got a smaller bag from the vet with the same packaging. He barely eats it and is still throwing up. I brought him to the vet to find out he has a uti and inflamed blader. BUYER BEWARE!!! This new packaging with the black on it is not good. The all white one was the best. Ever since they changed I'm going to have to go to a different urinary brand.
I'm so glad I bought this because she devours this food. The other brand her previous owner got me I had to mix a bit of tuna in order for her to eat it and by the end of the day it's still there. This one I don't have to worry because by the time I get home it's all gone.
When I opened the Chewy box, there was nothing securing the food in place (paper, tissue paper, foam etc.) so a handful of cans were bent open deform the shipping process which leaked all over the other cans.
My cat Beans was put on this prescription food due to crystals in his urine. It has since cleared but will have to remain on this special food for the remainder of his life. He did get tired of of it so now i have to mix it with the Hills c/d prescription food The only drawback is that it is very expensive. But he is worth it.
My kitty was ill with MAP Crystals. It was scary and devastating for both of us. She was put on a strict diet to prevent the crystals from forming. Just like her human counterparts, she refused to eat the prescribed selection of foods. She did not recognize it as “her food”, so she walked away from it. Finally, I ordered Purina Pro Plan Urinary St/Ox and I am happy to report she eats it and loves it. I have regained peace of mind over my Chloe’s diet to dissolve MAP Crystals. Thank you Purina Pro Plan. Vicki & Chloe
We have a cat that refuses to eat anything but seafood flavor dry food. So when told he needed to eat this special cat food for urinary problems I didn't hold out much luck that we could get him to heat it. HE LOVED IT FROM DAY 1! And feeling much better now.
I am very disappointed at the expiration date on my cat's prescription cat food. The bag I received from the vet two months ago expires 8/2024. The bag I just received from Chewy has a 6/2024.
My boys have been eating this food for, something like, 9 years. One cat has feline lower urinary tract disease and my other doesn’t. They both love the food and it makes them thirsty so they drink more water; water intake is even more imperative for male cats. They were out of this food for a week and the water intake was dramatically less. A special shout out to Chewy here. I usually call in my order to my veterinarian, they order the food, and it arrives within a week. After 2 weeks of waiting- my vet never actually ordered the food. They gave me a prescription to add and order here through Chewy. It was only my second Chewy order ever and the customer service was top-notch. Some of the best I’ve ever received with an online company.
Our cats have been on this food and healthy and happy for 5+ years. Now they are vomiting and dehydrated and refusing to eat. We thought they were all mysterious sick but turns out it's the change in formula. This is dangerous for a manufacturer to do. I contacted Purina and no response. Not happy at all, we are in process of finding new medical food option for crystals .
