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.

A rare category

All 3 of my cats have been eating the SO Moderate dry food for over 6 years, and they have not gotten tired of it. One of the cats must be on the SO, and it has been perfect for him. He has stayed well ever since he's been eating Royal Canin SO!

All My Cats Love It!

Have been feeding this product to a male feline because of urinary tract blockages. We have four other cats who also love this food and try to 'steal' it from Smokey Bones, the intended consumer. Smokey has been doing very well on this product with no more urinary problems.

Worth the price!!!

My 14 year old domestic long hair Tucker has been on Urinary S O since his surgery for crystals blocking his Urinary tract in 2006. He has not had any issues since!

Life saver

I have two male cats that haverhaver a history of kidney stones and blockage. I have almost lost them both to it. Since switching them exclusively to this food they haven't had any issues. Plus they love the taste and size of the kibbles. Thank you!

Must be delicious.......

All seven of my cats love this, even though only one is required to eat it. They prefer these dry bits over all other brands.

Cats has lived much longer than expected.

Her kidneys started failing at an early age. I believe that feeding this diet has extended her life expectancy far more than otherwise. I am very happy with this product.
