Royal Canin Feline Urinary S/O Cat Foods




Royal Canin Feline Urinary S/O Dry Cat Food

Formulated with reduced magnesium levels, a natural component of struvite crystals, and low RSS to help lower the concentration of ions contributing to crystal formation. Urinary S/O supports your cat’s urinary health and helps reduce the risk of urinary crystal and stone formation. Urinary S/O can be used to dissolve struvite stones and reducing their recurrence through its urine acidifying properties and its low level of magnesium. Urinary S/O also creates an unhospitable environment for the further formulation of struvite and calcium oxalate stones.

Royal Canin Urinary S/O creates an acidic urine pH, effectively dissolving struvite stones and helping prevent their reoccurrence. It helps to decrease the concentration of crystals present in your cats urine by increasing their water intake to actively dilute the urine. It also creates undersaturated urine, which is an environment in which crystals cannot proliferate, helping to reduce the recurrence of struvite and calcium oxalate stones. Urinary S/O contains low levels of magnesium, one of the main building blocks of struvite stones. In older cats, kidney function should be checked before Urinary S/O is prescribed.

Key Benefits:

  • Acidifies urine to dissolve struvite stones
  • Creates an unfavourable environment for the formation of struvite and calcium oxalate stones
  • Dilutes urine to reduce the concentration of urinary crystals
  • Low magnesium to limit the building blocks of struvite stones

Not recommended for chronic renal failure, metabolic acidosis, heart failure, hypertension, in conjunction with the use of urine acidifying drugs, pregnancy, lactation, or in growing kittens.
