Royal Canin Cat Veterinary Dry Food Adult Urinary S/O - 7kg

Royal Canin Urinary S/O Cat Dry Food 7kg is a complete veterinary diet formulated for adult cats requiring nutritional management of urinary tract conditions, including struvite urinary stones and the risk of urinary crystal formation.

Developed to support bladder and urinary tract health, this specialised formula helps dissolve pure struvite stones, reduce the risk of struvite recurrence, and create urinary conditions less favourable to the formation of both struvite and calcium oxalate crystals.

Its nutritional approach combines urine dilution, Relative Supersaturation (RSS) management, and controlled magnesium levels to support urinary stone management under veterinary supervision.

The 7kg bag provides a larger supply for cats following an ongoing veterinarian-prescribed urinary diet.

Veterinary Guidance Required: Royal Canin Urinary S/O is a therapeutic veterinary diet. Consult your veterinarian before starting, changing, or continuing this food.

Why Choose Royal Canin Urinary S/O?

1. Specialised Veterinary Nutrition for Urinary Health

Urinary tract conditions can cause discomfort and may require a combination of veterinary treatment, monitoring, and dietary management.

Royal Canin Urinary S/O is formulated specifically for the nutritional management of certain urinary stones and crystals.

Unlike standard adult cat foods, its mineral profile and urinary nutritional approach are designed for cats with diagnosed urinary concerns.

2. Helps Dissolve Struvite Stones

Struvite stones contain magnesium, ammonium, and phosphate.

Royal Canin Urinary S/O is formulated to help create urinary conditions that support the dissolution of pure struvite stones.

This makes it a nutritional option for veterinarian-supervised struvite stone management.

Important: The formula helps dissolve struvite stones, not calcium oxalate stones. A veterinarian must determine the appropriate treatment based on the type of stone involved.

3. Helps Reduce Struvite Stone Recurrence

Some cats may develop urinary crystals or stones more than once.

Royal Canin Urinary S/O is designed to help reduce urinary conditions that favour struvite formation.

This can support ongoing dietary management when a veterinarian recommends continued feeding.

Regular monitoring remains important because urinary problems may recur despite nutritional management.

4. Supports Calcium Oxalate Stone Risk Reduction

Royal Canin Urinary S/O is also formulated to help create a urinary environment less favourable to calcium oxalate crystal formation.

This supports the management of future stone formation risk.

Existing calcium oxalate stones cannot be dissolved by diet. They require veterinary assessment and appropriate treatment.

5. Promotes Urine Dilution

Concentrated urine can increase the concentration of minerals involved in urinary crystal formation.

Royal Canin Urinary S/O is designed to encourage increased urine production, helping dilute these substances.

Urine dilution is an important part of the formula's urinary nutritional approach.

Fresh drinking water should always be available.

6. RSS Methodology for Crystal Management

RSS stands for Relative Supersaturation.

It describes the degree to which urine is saturated with substances involved in the formation of specific urinary crystals.

Royal Canin Urinary S/O uses RSS principles to help reduce urinary conditions that favour struvite and calcium oxalate crystallisation.

This is one of the formula's key nutritional features.

7. S/O Index for Urinary Support

The S/O Index identifies the formula's nutritional approach to promoting a urinary environment less favourable to struvite and calcium oxalate crystal formation.

It works alongside the formula's controlled mineral profile and urine-dilution approach.

8. Reduced Magnesium Content

Magnesium is one of the mineral components involved in struvite formation.

Royal Canin Urinary S/O contains reduced magnesium levels as part of its specialised nutritional formulation.

This helps support struvite stone management.

9. Complete Nutrition for Adult Cats

Royal Canin Urinary S/O is a complete veterinary diet formulated to provide adult cats with essential daily nutrients.

It can serve as the main food for suitable adult cats when prescribed by a veterinarian.

The appropriate duration of feeding depends on the cat's diagnosis, response, and veterinary recommendations.

10. Practical 7kg Packaging

The 7kg bag provides a larger supply for cats following an ongoing veterinary urinary feeding plan.

It can be convenient for owners who have already confirmed the formula's suitability with their veterinarian.

Store the food correctly after opening to help maintain freshness.

Important Veterinary Feeding Recommendations

Follow the Prescribed Diet Consistently

Royal Canin Urinary S/O is designed for a specific nutritional purpose.

For the diet to work as intended, your veterinarian may recommend feeding it exclusively.

Other foods and treats can affect the nutritional balance of the urinary management plan.

Encourage Water Intake

Fresh drinking water should always be available.

Providing multiple water bowls or a suitable cat water fountain may help encourage drinking.

Ask your veterinarian whether compatible urinary wet food would be appropriate.

Monitor Your Cat's Urinary Habits

Watch for:

• Frequent attempts to urinate.
• Straining or discomfort.
• Blood in the urine.
• Changes in urine volume.
• Urinating outside the litter box.
• Reduced appetite or unusual behaviour.

Emergency Warning: If your cat is straining to urinate but producing little or no urine, seek immediate veterinary care. A urinary blockage is a medical emergency, particularly in male cats.
