Royal Canin Urinary SO Moderate Calorie is a veterinary-exclusive dry cat food developed to nutritionally support your adult cat’s urinary tract and bladder health. This formula promotes a urinary environment unfavorable to the formation of both struvite and calcium oxalate crystals. It increases the amount of urine your cat produces to help dilute excess minerals that can cause crystals and stones. Moderate calorie content helps them maintain a healthy weight. Relative Super Saturation (RSS) methodology is used to help lower ion concentration in urine, which contributes to stone formation. Lower urinary tract issues may be a recurring concern for some cats. Talk to your veterinarian about keeping your cat on this urinary cat food for long-term urinary support.
Key Benefits- A veterinary-exclusive dry cat food for cats prone to weight gain with urinary health concerns.
- Helps dissolve pure struvite stones and helps prevent calcium oxalate stones.
- Moderate calorie content for ideal weight maintenance.
- Lowers the risk of crystal formation using RSS methodology for bladder health.
- Supports urinary health with an exclusive S/O Index, and creates an environment unfavorable to crystal formation in the bladder.

It is recommended that your cat be fed 2 - 4 equal portions of the diet per day.
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% |

By katcat on Jul 26, 2021
Thank You for carrying Royal Canin Prescription Food, Hills did not work for my cat... a year later a second surgery had to be scheduled for my cat, but not performed the second time! Royal Canin cleared up her 2 bladder stones in 3 weeks and has kept her clear ever since, 7 1/2 years so far! And Thank You again, for carrying the Moderate Calorie choice!!! With such limited choices on prescription food and no desire to withhold food from only one of my cats, the fat one, I was becoming very concerned about how I could slim her down and Bingo! Royal Canin Moderate Calorie in her prescription is right there at my "Chewy.com"! And it works!!! The calories are cut back enough to be just right Thank You for carrying Royal Canin Prescription Food, Hills did not work for my cat... a year later a second surgery had to be scheduled for my cat, but not performed the second time!

Used to be great! Not now…
By Computerguru on Sep 22, 2021
We have had our cat on this for 4 years and she did great! UNTIL product was hard to get in early 2021 then as soon as we started new bag, urinary issues came back. We are taking cat back to vet today for second urinary infection in 7weeks! It sounds like Royal Canin changed something in the product so we will have to find a different urinary food for our cat.

Cats seem to like it
By Crystals on Sep 10, 2021
One of our cats was diagnosed with crystals which are treatable/controllable with better diet so we decided to switch to a better vet prescribed dry food and once I got over the price shock (I went from paying $25 for a bag of food to about $80 for this one and 1.5lbs less!) switching was easy. I have 2 cats and they both adjusted no problem. As to the cost I think it’s outrageous (doesn’t matter where you choose to buy from).

Great but expensive
By Kevinsmom on Sep 7, 2021
This is the only prescription food my cat likes and he needs it to avoid another urinary blockage. It works well to keep him out of the vets office so far. Although I love everything about Chewy, I pay $91.00 per bag for this food (it’s ridiculously expensive everywhere ~ no reflection on Chewy) and that seems quite expensive for a food that is necessary for my cats’ health.

Amazingly wonderful service
By JGrimm on Aug 26, 2021
Chewy has been a life saver literally for my 2 cats. They rely on Prescription Urinary SO dry food to keep them from having blockage issues. I can call and talk to a Rep, this time Kathryn, and get all the information I need, Always. So incredibly grateful for their assistance, patience, kindness, expertise!!!! Would so recommend them and their support staff for food, accessories, toys, etc.; everything that I need, I order from them. THANK YOU!

My furr baby likes it
By Creen on Sep 10, 2021
My cat has urinary problems and has to take special food for it. She really likes this (she did not like Science Diet). I try to get her the SO snacks too. I started buying the smaller bags because she does not like it if it has been exposed to the air for too long. This has worked out well

nope - didn't work
By Catwithcrystals on Sep 13, 2021
I used this & she was under a vets care for about 4 months, then she passed. It never helped the crystals; intact, I saw more in the litter box & this is all I fed her in the end. This is not a fix all or eve a band aid. I hope t works for you. I did not for my cat.

Cat urinary health without excess calories is the way to go
By Stefan on Aug 1, 2021
We were recommended a couple brands by our vet, but the dry Urinary SO - Moderate Calorie variant was a clear winner with our cat. Shelf life is quite impressive and our cat is excited for mealtime every time. We make the 17lb last for months with our single cat. My vet warned that other non-moderate calorie brands of Urinary health-focused cat foods can cause excessive weight gain. Happy to report our kitty hasn't had any weight issues following the recommended dose on the bag.

Love chewy!
By Diesel on Jul 26, 2021
I’ve had my cat on this food for about 2 years. He’s a little chunky so I found the moderate calorie (which I have my dog on the moderate calorie dog version as well, expensive babies) and was so glad to have found moderate calorie for my cat! Not to mention the shipping was so fast I was shocked when it came so quick being an approval item! Thanks chewy!

Speedy Service!
By Ashley on Jun 30, 2021
I've been struggling to get this dry food from two different vet clinics because because of the pandemic and delayed shipping to them from Royal Canin. I was finally told by the receptionist that I could easily order it from Chewy! Thank you for the simple process and speedy delivery. I've been buying this for my crew of 4 cats for the last 7 years after one of my cats had a urinary blockage. He's been healthy since 2014!
