HELPS PREVENT STONES: Specialized adult cat food helps dissolve pure struvite stones and helps prevent calcium oxalate stones

WEIGHT MANAGEMENT: Low calorie cat food (10% less calories than Royal Canin Urinary SO Dry Cat Food) for ideal weight maintenance

BLADDER HEALTH: RSS methodology for cat bladder health helps lower the risk of crystal formation

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

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. Moderate calorie content (10% less than Royal Canin Urinary SO dry 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 wet cat food and treats to complement your cat’s diet.

My Functional Feline!

I have a 7 year old male Maine Coon mix named Allen! This Royal Canin food has kept him functional, alive and healthy! Thank goodness for this food! Five years ago he had a blockage. It was bad. He was hospitalized for 5 days and if I would have brought him to the vet even an hour later he may not have made it. I have had him on Urinary SO Mod Cal ever since and he hasn't had a single UTI, crystal, blockage etc. This food is truly keeping him healthy, happy and being the lion of his kingdom!

Saved my cat

One of my 4 cats started having urinary problems. He was in pain and I was hundreds of dollars in vet fees. I put all 4 on this food and he experienced same day relief. They have thrived on Royal Canin. And by the way, their customer service is great.
