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.

Life saver

This food has given me peace of mind for a more than one kitty... I have one little girl kitty that has had issues with stones and this is the only food that keeps those away. But my mom also has a little boy kitty that has gotten two blockages.... after the first one he was switched to another urinalysis care type cat food. And then after the second time he had to be unblocked he was switched to this and everything has been fine since. We were worried nothing would help since switching to only good wet foods with plenty of water didn’t help. We were worried he would have constant issues and wouldn’t be with us long as the two blockages were a month apart but it’s been about a year and no worries so far:) so glad this was recommended by our vet.

Cat loves it!

Our cat Hobo loves the flavor of this food. He was getting some higher levels in his urine and the Vet suggested we put him on Royal Canin Urinary SO. He doesn’t mind at all and I feel less stressed in worrying about what food to buy.

Did its job

I’ve used this product for many years after finding out my cat was prone to having crystals form in her urine. Since starting it, she’s never had any more signs of crystals. The moderate calorie formula has also been great at keeping her at a healthy weight!

Good but expensive

My cats have been on this over a year. I had no choice but to use this product for my male cat because my 2 females needed to be on a lower calorie food and although they did not need a urinary formula this was the only brand that made a moderate calorie. Would not be my first choice because of price when 3 cats are on it.
