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.

DO NOT BUY THIS. DRAMATIC CHANGE IN THE FORMULA.

Loved this food. Saved my cat's life. I'm willing to pay anything for her to be happy, healthy and stone-free! When the vet prescribed this for her, I thought about how picky of an eater she is, but she (and my other cat!) took to it IMMEDIATELY. Their coats are shiny and overall health is better than ever. In the last couple months, Royal Canin changed the formula. The texture, consistency, "flavor" (or smell, I guess) are ENTIRELY different. My cats won't eat the new formula. Don't buy this, it's garbage. What's worse is that Royal Canin jacked up the price an additional 15-20%. We will be asking our vet to recommend an alternative. Really, really disheartened with this company. Bad marketing decision. Bring back the old formula. TL;DR: New version is thin & watery, smells bad, COSTS MORE, weird "shreds" instead of little chunks, CATS HATE IT.

Cats LOVE it!

My Two cats love this food. They have their heads in the can as soon as the top pops and can’t wait to eat it off the plate. They are loosing weight too. I also find they need to eat less kibble after eating the wet food.

Not my cat's favorite

Maybe because it's 'diet'? I feed it sometimes anyway to keep him svelte.
