Idiopathic cystitis : Thanks to the high moisture content of wet food, Urinary S/O Feline increases urine dilution. Nearly 64 % of cases of flutd are idiopathic cystitis and wet diet is recommended in cases of recurrent cystitis. Struvite dissolution : Urinary S/O Feline effectively dissolves struvite uroliths. Low RSS : Undersaturated urine creates a urinary environment unfavourable to the development and proliferation of struvite and calcium oxalate crystals. Urine dilution : Diluting urine decreases the urinary concentration of struvites and calcium oxalates. The larger urinary volume also helps ensure more frequent bladder emptying.
