Royal Canin Feline Urinary S/O Loaf Adult Wet Cat Food is a complete dietetic feed for cats. Its urine acidifying properties and its low level of magnesium make it suitable for dissolving struvite stones and reducing their recurrence. It is also formulated for the nutritional management of cats with lower urinary tract disease. In cases of recurrent idiopathic cystitis, Urinary Wet is recommended. Key benefits: Struvite dissolution - Urinary S/O Feline effectively dissolves struvite stones. Urine dilution - Diluting urine decreases the urinary concentration of struvites and calcium oxalates. The larger urinary volume also ensures regular bladder wash out. Low RSS - Undersaturated urine is an environment where crystals cannot proliferate and so is unfavourable to the formation of struvite and calcium oxalate crystals.
