HELPS DISSOLVE STONES: Innovative urinary tract cat food helps dissolve pure struvite stones and helps prevent calcium oxalate stones

BLADDER HEALTH: Lowers the risk of crystal formation using RSS methodology for cat bladder health

S/O INDEX: The exclusive S/O Index creates an environment unfavorable to crystal formation in the bladder to support urinary health

HELPS PREVENT STONE REOCCURANCE: Specialized diet, with a reduced level of magnesium, helps prevent struvite stones from reoccurring

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 dry 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. 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. And this specialized nutrition, with a reduced level of magnesium, helps dissolve pure struvite stones and prevent struvite stones from forming. 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 wet cat food and treats to complement your cat’s diet.

Excellent Food

Started buying this food 5 years ago after my cat had surgery to remove crystals from his bladder. He hasn’t had an incident since. I’m very happy about that.

Keeps my cat healthy

My cat suffered with a urinary blockage almost a year ago. Our vet recommended this prescription diet to avoid a blockage from ever occurring again. I’m happy to say we haven’t had any issues thus far and my cat genuinely enjoys this food. No pebble of food is left behind! I feel secure feeding our cat this food knowing it protects him from any future blockages. Each time we visit the vet for a checkup, Buddie’s tests are all healthy! This is proof that Royal Canin’s food keeps him healthy. :)
