Product description

A complete dietetic wet food for cats 6 months+ which supports the treatment of lower urinary tract disease. Can help dissolve struvite stones and reduce the risk of recurrence.
Royal Canin Urinary S/O diet is formulated to specifically support the treatment of cystitis and urinary stones. Many cats suffer from recurring Feline LUTD (lower urinary tract disease), frequently with no apparent cause. Feline LUTD can also lead to urinary stones (struvite and calcium oxalate). If your cat has lower urinary tract disease you can help to support the treatment by feeding a diet that maintains the correct urine PH to dissolve struvite stones. By providing nutritional support for your cat’s urinary system you are also helping to reduce the risk of recurrence.
