Helps dissolve pure struvite stones and helps prevent calcium oxalate stones

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

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 loaf in sauce 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. 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 dry cat food and treats to complement your cat’s diet.

Best food for my cat

My little baby loves it and it is so easy for her to divest

densely packed great quality wet canned food

Our cat has been on this diet for 12 years as it was a recommendation from our vet due to crystals in the bladder.

Best SO food out there

My cat Jack had a blockage at 2 years old. He’s been on this food for 6 years now and he still eats it for every meal. We took him off for 6 months to another SO food when we switched vets per their recommendation and within that time he developed another blockage. We switched vets and food and have no issues since. Jack is healthy, playful and happy. He’ll be on this food the rest of his life.

Helps prevent urinary crystals

Before using the urinary S/O food we would make frequent vet visits for our cat Tigger who suffered from urinary crystals that would clog his system.

Helped eliminate Struvite crystals

Our vet prescribed this product to help eliminate Struvite crystals, which it accomplished so for that we're thankful. However, our cats on this diet have gained significantly more weight than their siblings that are eating other food.
