Helps dissolve pure struvite stones and helps prevent calcium oxalate stones

Moderate calorie content (14% less than Royal Canin Urinary SO Morsels in Gravy wet cat food) 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

When your cat has urinary issues, easing their discomfort requires special care. But with the help of your veterinarian and Royal Canin, there’s not just hope—there can be a true difference.

This veterinary-exclusive wet cat food was developed to nutritionally support your adult cat’s urinary tract and bladder health. It increases the amount of urine your cat produces to help dilute excess minerals that can cause crystals and stones. Moderate calorie content (14% less than Royal Canin Urinary SO Morsels in Gravy wet cat food) 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. This formula promotes a urinary environment unfavorable to the formation of both struvite and calcium oxalate crystals. 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. And ask them about the right Royal Canin dry cat food and treats to complement your cat’s diet.

New formula is HORRIBLE!! Please change back!

What have you done? Are you making a cheaper product now? This new formula is horrible and my cat who desperately needs this food (he’s a stone maker and had to have three removed at once) will not touch this stuff! It’s like mush! Please change it back! He’s a senior cat with kidney and urinary issues and changing his food upset his whole system and cause issues!

No more stones!

My cat was diagnosed with bladder stones about 6 months ago and was put on this food (wet and dry). Not only did she LOVE the food, but now her stones are completely gone! I am so happy with this food.

Kitties love it!

My cat was put on a diet by his vet and he has never been happier! He likes this way better than the regular SO canned food.

My cat Thor depends on this food. Since the formula change, he will not touch it. He has been on this food for nearly a year and absolutely loved it. He had a bad blockage a year ago and nearly had to have surgery. After eating this food along with SO dry food. The stones dissolved and surgery wasn’t needed. He loved the gravy in this food. But now he smells it and meows at me to fix it and I can’t. He then walks away. I don’t understand why when you have a product that is working so well and that everyone is so happy with. Why would you then make changes to this. Especially when this is a prescribed food. No warning was sent out to owners. Some I’ve read now have sick animals. I’m now concerned about Thor eating the SO dry food, is it safe. We have been loyal RC customers for 8 years and now I’m concerned, I will have to start looking for another pet food manufacturer for my cat. I have to feed him specialized food and he has to eat it. He won’t eat the new formula at all! This is a major issue! The new formula isn’t gravy anymore, it’s watery and oily looking. My cat is obsessed with rue this food and now it’s ruined. What am I supposed to feed him now??
