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.

Our kitty has been eating this food for a few years now by the recommendation of our vet, Dr. Rachel Savoy for urine tract issues because she has a tendency to have 2 different kinds of crystals in her urine.
