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 two boys love it!
By MindyMN on Apr 30, 2021
I’ve been looking for something new to give my guys a little variety in their diet since they’re on veterinary prescribed urinary support food. I only realized recently that Purina has a veterinary line of food, too. I decided to try the kibble and mix it with some of their Science Diet CD. It was a hit! I just bought my second bag of Purina and am now giving just that. Wish they were as fond of the canned options, but I’ll keep trying! Thumbs up to this dry mix, though!

My cats love this food
By Phoebe on Apr 8, 2021
My cats had been on the Royal Canin Urinary SO prescription diet dry food for about 5 years. I had to choose and alternative as the RC food was out of stock with Chewy and it looked like it would be for an extended period of time. My veterinarian recommended the Purina Pro Plan Urinary formula, I was a little worried that they might not like is as they can be picky eaters. For a couple of weeks i mixed it with what was left of the Royal Canin and they gobbled it up. Now they are on the Purina exclusively and it was a seamless transition, I would definitely recommend this food to any cat owner who is looking for a prescription urinary dry food diet.

Surprisingly easy to switch!
By RebeccaB on May 4, 2021
One of my three cats just had bladder stones removed, and we found out she had struvite stones. So, this was one of the two recommended foods from the vet. We were hopeful that since they all already ate Pro Plan food, she would switch over okay. It went great! She loves her new food and the other two are starting to recover from the jealousy!

A good option as a dry cat food for special urinary SO diet
By MichiganBarb on Apr 21, 2021
Chewy let me know that my preferred brand of urinary SO cat food was backordered, and suggested that I find another option. My vet prescribed the Purina ProPlan dry cat food, but suggested that I mix it with the previous brand (Royal Canin) in order to transition. My cat loves it! I can tell from the kibble that she leaves in the bowl that she definitely prefers it, so I am happy that it is good for her.

Give it a try
By CatMama on Mar 24, 2021
I have one cat on a urinary diet and the other does not need it. But, I buy only urinary food in case the one who needs it eats it. The cat who does not need it moved in about a year ago and didn't like the urinary food we used. So, I gave this one a try. The long-term resident doesn't like this food but the picky newcomer who doesn't like the other food loves this one. So, I buy this and the other brand and everyone is happy. The only thing I don't like is that the bag is NOT resealable. You will need a clip or rubber band or something to keep it securely closed.

Our boys love this!
By BoysAtHarperHotel on Apr 1, 2021
When one of our boys was diagnosed with idiopathic feline cystitis last year the vet prescribed this brand. Since both boys eat out of the same bowls, we were concerned about both cats liking it. Oh, and they don't like seafood flavors. There was never an issue! Both cats absolutely LOVE this food, both the dry and wet formulas. We saw in some reviews their kitties didn't like this brand or flavor but we consider ourselves and our boys very fortunate.

Catz love it!
By Magz on Apr 9, 2021
My kitty turned his nose up at the last dry food I bought him (prescription) but he loves this! No hesitation at all! I'll be really happy as long as we do NOT have to address the same issue again! On top of that, Chewy gave me a refund on the food my cat would not eat and offered to let me buy another one (this one) and not pay shipping! I really appreciated that!

My cats love it!
By Alexia on Mar 16, 2021
I had to switch over to this food because one of my cats got a very severe urinary block. Because my cats get jealous if one another, they all has to be switched over (I mix it with their previous food to make it last longer). My cats go CRAZY over it, they all scarf it down and come running when they hear me open up the bin. I was skeptical at first, because when my dogs to do be switched over the prescription food they hated it. But all four of my cats thoroughly love this food! (My vet gave me the okay to allow them all to eat it).

He will eat it!
By January on Apr 19, 2021
Vet recommended this for five year old cat with recurrent urinary tract issues. He's willing to eat it, so that is a good part of the battle. This has no "calming agents" which are apparently part of other brands. We'll see.

My Fussy Cat Likes It!
By 1Starfish2 on Feb 26, 2021
I am so relieved and happy that my cat, Rudy, enjoys eating this Proplan prescription urinary dry food. I have tried feeding him Royal Canin and Hills’ brands but to no avail. And a definite bonus is that my other cat also likes the taste of this food! And importantly, so far since Rudy has been eating this food, he has exhibited no urinary problems! If you have tried countless other brands with little or no success, I recommend you give this one a try!
