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% |

Keeps my Sophie healthy
By Petra on Sep 14, 2021
My Sophie (age 9) started to get an UTI infection yearly when she was about 5 years old. Lots of pain and suffering, vet visits, medications. My vet then prescribed this food and she loves the taste of it and for the past 4 years did not get an infection. It is pricy but well worth every penny for keeping her healthy and pain free. I'd rather spend the money on this food than a yearly high vet bill. I just wish it would not require a prescription because it is a hazzle to get from my vet. Thank goodness Chewy is very helpful and consistant to contact the vet.

Just add water--Cured Bladder Stones
By MrsNeuby on Aug 23, 2021
My cat was diagnosed with bladder stones after he started urinating outside the litter box, grooming himself a lot after urinating, and having blood in his urine. Extra moisture/water was recommended by the vet to help flush the stones as well as this special diet. The price per serving was higher for the wet food, so I did the next best thing. I got the dry food and added warm water! He is 14 lbs so twice a day I give him 1/3 cup food plus 3/4 cup warm water. He loves it! Drinks all the water, tries to bury the food, then comes back a few minutes later to eat it all gone. We went back 11 days later and the vet did a urinalysis and his stones were cleared!! He is on this for life, I'm told My cat was diagnosed with bladder stones after he started urinating outside the litter box, grooming himself a lot after urinating, and having blood in his urine.

bad batch from Purina?
By scorch on Sep 22, 2021
not sure exactly what the issue is, but only one of my cats is eating from this most recent bag. The other's will have a few bites but end up having no interest in eating. I have already updated my autoship to switch brands back to one I know they will like. Maybe it is just a bad batch? Something the cats know and I dont I guess. But, I cant let them go on not eating full meals.

Cat wont eat it
By Food on Oct 9, 2021 top50Contributor
Tried this brand of food for our kitty with crystals since he pukes up on hills C/D and refuses to eat royal SO anymore. He wont eat this at all either. Other than certain wet food, i feel I've run out of dry food options for him to eat.

Keeps my baby healthy
By Miranda on Aug 14, 2021
My cat had a blockage and this good was recommended by our vet. Not only has he been doing great but he’s obsessed with this food. He knows his siblings get different food and he has no interest in any other food but this one unless he HAS to eat something else.

Purina UR for cats
By Sherry on Jun 22, 2021
Only one cat is required to eat this but I can’t keep the other 8 away! It’s cheaper than the Hills S/D she was on but now I’ve got to mix it with the other’s Hills W/D so they leave her alone! Lost a star because Purina doesn’t package the same. Hills has a Velcro closer which is VERY convenient, so until I get that one empty to reuse, I have to use all sorts of containers for the Purina(17 lb bag!).

Half and Half
By Addie on Aug 31, 2021
The first bag was great, just like the others we had ordered in the past. The 2nd bag the cats will not touch. The food reeks of chemical and the kiblets look old.
