About Royal Canin Urinary Health for Cats

Worried About Your Cat’s Urinary Health?

Your veterinarian is the expert on your cat’s health, so you should always consult with this trusted advisor to find the best urinary health solutions for your pet. Royal Canin works closely with veterinarians to develop cat formulas that help support urinary tract and bladder health.

How Can Nutrition Help?

Your veterinarian may recommend a Royal Canin Urinary cat food formula for your cat. These special formulations can:

Dilute Urine

This helps your cat urinate more often, which can help minimize time for stones to form.

Lower RSS

RSS methodology predicts urine crystallization and is used to develop diets that reduce the risk of stone formation.

Maintain Balance

A precise mineral balance can also help prevent stones from forming.

Set Up Autoship for Consistent Delivery

Last-minute dietary changes can sometimes upset your pet's stomach. Set your Royal Canin pet food order to Autoship to keep feeding on track and avoid unwanted disruptions.

About Royal Canin

What sets Royal Canin apart is their close collaboration with veterinarians. Through these professional partnerships, they strive to learn everything they can about pet health, including how different formulas perform for different breeds, sizes, lifestyles and therapeutic conditions. Ongoing research and development allows Royal Canin to keep providing the precise nutrition cats need for a range of medical conditions.

Please click on the attached picture for the Feeding Chart to reference. The chart may also be found under the "Feeding Instructions" tab on the product page.

My cat is presently on Veterinary Diet Urinary SO but he also eats about a TB of this daily to take medicine, making the can last 5-6 days. No stomach upset, smells fine, but is it too long to store in a 35 degree fridge?
Answer by ChewyOct 16, 2018
Opened cans should be stored in the refrigerator, at temperatures between 40 to 45° Fahrenheit, for a maximum of 5 to 7 days. Any cat or dog food remaining after that time should be discarded.

Is Urinary SO Grain Free?
Answer by ChewyJun 06, 2018
This product is not grain-free.

I was feeding my cat RC Weight and Hair and Skin and she will eat that any time day or night with fervor. This high priced food was totally rejected by my cat. I tried mixing it with RC Hair and Skin and I swear she sorts out the Health and Skin and leaves all the SO behind. Unfortunately, I now have almost a whole case of the 5.1 oz that will never be consumed by, at least, my cat. My advice to you all would be try a less expensive brand that might just do the same thing to correct your cat's issues. And, no, I would not recommend it.

Nearly impossible to afford

My cat has to be on this diet due to having crystals surgically removed back in 2017. She is on the dry food of this kind as well. They both have gone up in price so significantly that I won't be able to afford it in the new year. It used to be around $55 maybe 2 years ago and now it's $75. the 18 lb bag of dry food went up from $75 to $120! It's absolutely ridiculous and impossible to afford it. My cat HAS to have this diet and there's nothing else they make like it for crystals. She does seem to like it. Also, they quit making the bigger cans and still the same price.

So far so good

My 18 month old male kitty just went threw hell with a urinary blockage. It waxed and waned for a couple months until the blockage occured. How I wish we would have started this food at the first sign of issues! He's about to stop his course of steroids, which is when his urinary issues would start up again in the past. He seems to be 100% himself again. which we haven't seen in months. Fingers crossed this food does the trick, but it seems to be helping my boy a lot!

So far my cats love this food

My cat has to go on this to try to eliminate recurring urinary stones and so far it’s working and he at least likes it and it’s going well so far no real complaints except the price and I guess that’s normal for any prescription cat food but good quality my kids love it and so far it seems to be working

Great for my cat’s bladder inflammation

My cat was urinating all over the house due to bladder inflammation caused by anxiety after changes in the household. The changes calmed down but she still had inflammation. Vet recommended this food and she slowly stopped urinating outside her litter box after a month of use. I keep her on this to maintain her bladder. Good prescription food

118% price increase over 6 years

Sadly, this is the only Urinary SO wet foot my cat will eat. I’ve been buying for exactly 6 years, and have seen the price per ounce go up 118%. My hands are tied, because what else can I do? Not give my pet the Rx food he needs to survive? Royal Canin shouldn’t be doing this to us.

Olivia will be on the SO for the rest of her life and she's only 9 years old. She just had bladder stone surgery. I am so glad she's eating it because there are not many options for her. She comes up next to me on the couch, looks at me and taps me with her paw when she wants me to get a can for her. I sit and watch her eat it and she seems to really like it. So far, so good.

Best Food My Cats Ever Had - Apparently

I started on this food out of necessity since one of my cats tends to form bladder stones. But much to my surprise, both cats (siblings) love it, can't get enough of it. Reading the can, it is quite scientifically formulated and worth the extra cost. I would definitely recommend any of the Royal Canin non-prescription foods, I'm sure they are all exceptional.

New food

My 5 year old male cat, Beau, had bladder stones & surgery. Now he must be on a special diet. He’s a picky eater & he loves this food & their dry version.
