Provides nutrition that aids the management of pure struvite uroliths

Increasing the urine volume reduces the saturation of urine with calcium oxalate and struvite crystals

Relative Supersaturation (RSS) methodology predicts the crystallization potential of urine. RSS is used to develop diets that lower the concentration of ions contributing to struvite and calcium oxalate urolithiasis

Reduced level of magnesium, a natural component of struvite stones

Specially formulated to assist in the management of lower urinary tract disease in cats.

Fantastic Food for our Male Cat!

When we adopted our cat he had problems with urine control. We tried several other products, stopped giving him food with fish in it, and nothing helped. He gained alot of weight and was freqently in pain and we had to go to the vet alot to relief the bloating pressure. Over a year ago the vet suggested using Royal Canin Urinary S0 dry food. Our cat is now at his normal weight and no longer has urinary tract issues.

Saved my cat's life

I still think this food was necessary to save my cat when he had 3 urinary blockages in a row. He still has some kind of bacteria in his urine and also drinks bottled water. But when i've switched from this food he immediately starts getting sick

keeps my cat healthy

I use this dry food as well as the canned and it keeps his crystals low in his urine. However, his breed is Bombay and it hard to control his eating habits as there are two other cats in the house. It would be nice if the food was low cal.

Crunchy texture and doesn't have sandy residue

I buy this regularly he has been on this since he was 4 is now 8. It would be nice if you had this in a senior formula.

Good for health but lacks in taste

My cat hasn’t had any further complications since switching to this food after a blockage. However, he doesn’t eat as much as he used to.
