Product Description

Product Overview

Royal Canin Urinary S/O – 1.5kg is a complete veterinary dietetic dry food for adult cats, formulated for the dissolution of struvite stones and to help reduce the recurrence of struvite stones when used under veterinary guidance.

The formula is designed with controlled levels of key minerals including magnesium, calcium and phosphorus and helps create an appropriate urinary environment through urine dilution, controlled urinary ion concentration and urine-acidifying properties.

Royal Canin Urinary S/O also has a low Relative Supersaturation (RSS) approach, which helps reduce the concentration of ions involved in urinary crystal formation.

Because this product is part of the Royal Canin Veterinary Nutrition range, Royal Canin recommends obtaining advice from a veterinarian before use and before extending the feeding period.
