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. Indications: Idiopathic cystitis Prophylactic prevention of calcium oxalate stones Prophylactic prevention of struvite stones Stuvite dissolution Contraindications : Pregnancy, lactation, kittens Chronic renal failure, metabolic acidosis Heart failure Parallel use of urine acidifying medication Hypertension Key benefits: Struvite dissolution: Urinary S/O helps to dissolve struvite stones. Increases urine volume: Helps to reduce the risk of recurrence of calcium oxalate and struvite stones. Low RSS: Helps to produce urine with an unfavourable pH for stone formation. Also lowers the concentration of ions which contribute to crystal formation. Urine dilution: The high moisture content dilutes the urine and the minerals in the bladder.

Changing your pet’s diet and length of treatment: Your pet will need to stay on this diet for 5 to 12 weeks, or until the stones are dissolved.
