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% |

Great Food
By Kimmm on Jun 11, 2021
My cat is on a prescription diet due to having bladder stones in the past. This food literally saves her life. If she doesn't have this, she will develop them again. My boy cat is not prone to stones but vet said he can eat this diet as well. They both enjoy it a lot. Had no issues with transitioning them. I decided to try the moderate calorie this time around due to my cat being a little over weight and they still love it. 10/10 recommend this food if you cat has stone issues.

Royal Canin Urinary SO knockoff?
By Bandit on Jun 3, 2021
I was so upset when I opened my order when I noticed the bag opening was different. Then the color of the dry food was very pale and unlike the rich color of the dry food from Royal Canin that I have purchased for a couple of years. I had heard that Chewy was selling pet food that was not from the manufacturer as promised. Needless to say, I was very disturbed. I will likely cancel my auto orders. I can't believe you have lied to me and sold me a pirated product. How can I trust Chewy again?

Good food and an awful lot of it
By Jeanlou on Jun 15, 2021
This food has been good for my male cat who has a tendency toward urinary crystals; he likes it and it has helped keep him healthy. I really wish RC would make it available in smaller bags, tho — this is an awful lot of food, especially since we use it as s supplement to the canned version. As always, Chewy service is great with availability notifications and prompt shipping!

Max Likes It!
By TheCatLadies on Jun 14, 2021
Our cat Max has had no recurrence of the the UTI that nearly proved fatal for him since starting on this food. And, he actually likes it! We got nervous when our vet was out of the food and our supply was getting low. We checked several other vets, to no avail. Thankfully, Chewy came through!

Healthy & Full of energy!!
By KiKi on May 25, 2021
My Vet put KiKi on this food when she was only 2yrs. old because of a urinary track infection. It was the best thing she could have done !! She has not had a problem since and is full of silliness, fun, and energy now at 12yrs. old. I do believe that this food has a BIG part to do with this. Thank you for a great product !! D~

Parker loves it!
By Kate on May 19, 2021
And thank goodness, since he needs to be on this diet for the long term. I question the ingredients, but understand it is the processing of these which creates the diet for urinary tract issues. Parker is doing well now, and surgery has been avoided! Though expensive, I am grateful for my Parker's health!

Great product
By Lucky on Jun 18, 2021
My vet recommended this dry food because my male cat had a blockage. That was 1 year ago. Since then he has been fine Highly recommend. My other 2 female cats love it too.

My cat loves this dry food!
By HeatherM on Mar 24, 2021
My 3 year old cat was on the regular SO dry food until he started gaining too much weight, but he would only eat that food if he was really hungry. This food, though, is a whole different story. He often goes after this dry food with gusto and meows for more. We feed him twice a day, both the canned food and dry, and he seems to enjoy it very much. The only drawback is the expense. This dry food bag is smaller than the regular SO dry food, but costs the same. Overall, I realize the prescription food is more expensive than most non-prescription foods, but since my cat HAS to have prescription food to remain healthy, it seems like there should be some sort of moderation to the prices.

royal canin for cats
By Rider on May 25, 2021
I could not get this food from the vet they have been out of it and they do not have the same size bag as I got for the same price I spend at the vet for 1/2 the size.

He loves it! And took some weight off.
By Melissa on Mar 15, 2021
I was very happy that my cat, who has crystals, accepted this food so easily. Now that I feed him separate from the rest of the fur family, I took this opportunity to have him lose some weight (he always ate the leftovers...). We first tried Hills S/D, but he seemed to be GAINING weight with that, probably because it is so high in calories. Switched to this, and he took to it right away AND has lost that weight that we needed him to lose.
