Royal Canin Feline Urinary S/O is a veterinarian-exclusive prescription cat food that is specially formulated to help dissolve struvite stones and prevent calcium oxalate stones. It is a high-protein, low-fiber diet that is also low in magnesium.

How Royal Canin Feline Urinary S/O Works

Royal Canin Feline Urinary S/O works to dissolve struvite stones and prevent calcium oxalate stones in several ways. First, it contains a reduced level of magnesium. Magnesium is a mineral that is required for the formation of struvite crystals. By reducing the level of magnesium in the diet, Royal Canin Feline Urinary S/O helps to prevent struvite crystals from forming.

Second, Royal Canin Feline Urinary S/O is acidifying. This means that it helps to lower the pH of the urine. A lower pH urine is less conducive to the formation of struvite and calcium oxalate crystals.

Third, Royal Canin Feline Urinary S/O contains several ingredients that help to increase the solubility of struvite and calcium oxalate crystals. This means that the crystals are more likely to dissolve in the urine and be excreted from the body.
