Royal Canin Urinary S/O can be used to dissolve struvite bladder stones and is designed to reduce the risk of urinary crystal and stone formation. The wet formulation can also be used to manage feline idiopathic cystitis, the most common cause of lower urinary tract disease in cats.
Bladder stones are formed when mineral crystals in the urine combine to form stone like structures that sit in the bladder. Crystals and stones can come in many different mineral compositions, the most common two are struvite (magnesium, ammonium and phosphate) and calcium oxalate.
