Dechra Feline Specific Fcw Crystal Prevention Key Benefits: Low RSS struvite & oxalate: Low urinary RSS (Relative Super Saturation) values for struvite & calcium oxalate for undersaturation & low metastable saturation, respectively, to minimise the risk of new struvite & calcium oxalate crystals forming in the urine. Reduction of struvite recurrence: The diet has a reduced content of magnesium & phosphorus (components of struvite crystals) for reduction of recurrence of struvite crystals & stones. Urine p H control: A urine p H below 6.4 dissolves existing struvite crystals & minimises the risk of precipitation of new struvite crystals. High digestibility: High quality & highly digestible ingredients ensure an optimal uptake of nutrients from the diet, whilst reducing faecal output.
