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.

Cat loves it

My youngest is turning 5 this year and has been on the Moderate Calorie dry for over three years and has not had a relapse of crystals or plugs. All my cats eat this and enjoy it.

Easy to spot

I have been using this product for years as my cat was getting frequent bladder infections. The Feline Urinary SO Moderate Calorie has helped to reduce bladder crystals and prevent infections as well as keep his weight down.

Literally a Life Saver!

My black cat almost died and this food was recommended by my vet - it has kept my boy alive and happy, he can still jump on the kitchen counter at age 16. His little sister loves it too.

Great Product

I have been using this for several years due to a male cat who is prone to producing crystals in his urine. This product has been great at preventing the formation of crystals and avoiding Vet bills!

Healthy living for my kitty!

This food was an easy solution for my cat's urinary health issues. He had crystals forming in his bladder (the precursor to bladder stones) and he was in a lot of pain, but a week or two on this food and he was right as rain! There have also been no relapses or anything like that since. I'll most likely be feeding it to him and to my new (also male) cat for the rest of their lives to ensure they never have bladder stone problems. They also love the taste of it.

reliable results

This isn't cheap, but after our boy cat had a large gladder stone removed at four years of age, he has avoided building up any more, so we're happy.

Cats Love It!

I have a kitty who had bladder stones and has been eating this food for several years. The rest of the kitty family eats it too and they all love it. Even better, Fireball has had no more issues with bladder stones or infections.
