Transition Instructions
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% |

No more stones
One of my cats struggles from frequent bladder stones which was greatly reduced when we switched him to the over the counter Pro Plan urinary health. While that OTC food helped him a lot he would still get there occasional bladder stone. This most recent visit to the vet he recommended we switch him to this prescription food. Since switching him to the pro plan Vet diet we have not had anymore issues with bladder stones forming.
Purina UR is GREAT!
One of my cats gets UTI's, so my vet recommended Purina ProPlan UR dry food. Both of my cats love it!!! And it does just what it's supposed to do, which is to encourage your cat to drink water. Both cats are drinking a lot of water and urinating more often, so they are being flushed out, which will help my cat that gets the UTI's a lot. Thank you Purina!!!
Urinary St/OX
I was very surprised that my cat ate this because she is so picky but with her urinary problems, I hope this will help her. I would like to try a can of the wet food to see if she will eat it but don't want to buy a case until I see if she likes it. Is there any way I could do this?
Purina Pro Plan Urinary St/Ox
Product arrived promptly. Appreciate 16# size. Cats eat readily. Product is expensive compared to what I used to buy; however, price is lower than other on-line providers.
Usually great, bad experience this time!
My cat has been eating this food for almost 2 years. He is a very picky eater and this was the only RX urinary food he would eat. For whatever reason he has not seemed interested in this previous bag of food. After I dumped the food into a clear container I noticed there were several moths in the bag.
periodic issues
Every few bags, my cats refuse to eat this kibble. They are large cats with great appetites so I know there is something "off" with the food even if I can't smell it. Chewy has been great about replacing the bag when this occurs.
Mixed review
I ordered this brand because the Royal Canin cat food was unavailable. The cats seem to like the taste, but after a few days I noticed one cat was losing small clumps of fur and he also seems to have some bowel issues. I plan to switch back to Royal Canin when it is back in stock.
Great for cats with FLUTD
One of my cats was diagnosed with Feline Lower Urinary Tract Disease seven years ago and was prescribed a Purina UR diet as part of her treatment. She took to the UR dry food right away. Since beginning her prescription diet (which includes both the dry and canned UR food), she hasn't had any new health scares related to her FLUTD. Her brother, who was healthy, also went on the UR food when she was diagnosed, since they eat together and it would be difficult to keep them on separate foods. I don't know if he would have eventually suffered from any urinary issues on his old diet, but I can say that he's remained healthy on the UR diet. We are very happy with this food!
Price doubled
Great food for a cats system. But the price doubled since my last delivery. Not sure I will continue purchasing here.
Formula Change
We really loved and trusted this food until it changed. My cat preferred it over treats, and it helped resolve & prevent recurrence of his FLUTD & crystals for the past several years. Because we loved it so much, I was terribly disappointed when I found out the bag redesign wasn't the only change Pro Plan made to this food. It no longer contains chicken (previously the second ingredient), and Tuna has been added (as the fourth ingredient). In fact, Tuna is now the only meat in the food. This formula change was made without any notice on the bag or website, but I definitely found out when I checked the ingredients after the first feeding from the new bag made my kitty stinky and sick. He does not tolerate fish well at all, and fish is suspected as a possible factor in his previous urinary issues. For these reasons, I specifically chose this food along with the matching pate to provide a fish-free urinary rx diet. Unfortunately, we now have to switch, and Pro Plan does not offer an alternative fish-free urinary rx dry food, so we will likely need to look to other brands to meet this need. I wish very much that we could still rely on the excellent food this used to be, but more than that I wish the formula change had been noted on the bag or the website so I could have saved the cost of the food as well as the discomfort it caused my cat and the mess it left me cleaning up. It was a significant change to the formula, and customers would have been better served by a prominent notice. Even for kitties who do get to enjoy fish, I am not sure the sudden change in the formula will be kind to their tummies.
