Royal Canin Cat Veterinary Dry Food Adult Urinary S/O - 1.5kg
Support your cat's urinary health with Royal Canin Urinary S/O Cat Dry Food 1.5kg, a complete veterinary diet specially formulated for adult cats with certain urinary tract conditions, including struvite urinary stones.
Urinary stones and crystals can cause discomfort and serious urinary problems in cats. Royal Canin Urinary S/O is designed to help dissolve struvite stones and reduce the risk of struvite and calcium oxalate stone formation through a carefully controlled mineral profile and its S/O Index nutritional approach.
The formula uses RSS (Relative Supersaturation) principles to help create urinary conditions less favourable to crystal formation. Its reduced magnesium content also contributes to managing the mineral factors associated with struvite stones.
The 1.5kg bag provides a convenient supply of veterinary urinary nutrition for cats following a veterinarian-prescribed feeding plan.
Veterinary Guidance Required: Royal Canin Urinary S/O is a therapeutic veterinary diet. Use it only under veterinary recommendation, with appropriate monitoring and follow-up.

Why Choose Royal Canin Urinary S/O?
1. Veterinary Nutrition for Urinary Conditions
Cats with urinary tract problems may require a specialised nutritional approach.
Royal Canin Urinary S/O is formulated to support the veterinary management of certain urinary stones and crystals.
Unlike general maintenance foods, its nutritional profile is designed specifically for urinary stone management.
A veterinarian should determine whether this formula is appropriate for your cat.
2. Helps Dissolve Struvite Stones
Struvite stones are made primarily from magnesium, ammonium, and phosphate.
Royal Canin Urinary S/O is formulated to help create urinary conditions that support the dissolution of struvite stones.
This nutritional approach may form part of a veterinarian-supervised treatment plan.
Important: The diet is intended to help dissolve struvite stones, not calcium oxalate stones. Stone type must be assessed by a veterinarian.
3. Helps Reduce Struvite Recurrence
Cats that have previously developed struvite stones may require ongoing nutritional management.
Royal Canin Urinary S/O is designed to reduce urinary conditions that favour struvite crystal formation.
Its controlled mineral profile and urinary nutritional approach help manage recurrence risk.
Regular veterinary follow-up remains important.
4. Supports Calcium Oxalate Stone Risk Reduction
Calcium oxalate stones are another type of urinary stone that can affect cats.
Royal Canin Urinary S/O is formulated to help reduce urinary conditions that favour calcium oxalate crystal formation.
However, calcium oxalate stones cannot be dissolved through dietary treatment.
Existing calcium oxalate stones require veterinary assessment and appropriate management.
5. S/O Index for Urinary Crystal Management
The S/O Index is a nutritional feature associated with Royal Canin's urinary diets.
It indicates that the formula is designed to help create urinary conditions less favourable to the formation of struvite and calcium oxalate crystals.
This is one of the formula's key characteristics.
6. RSS-Based Nutritional Approach
RSS stands for Relative Supersaturation.
It describes how concentrated urine is with the substances involved in forming particular crystals.
Royal Canin Urinary S/O uses a nutritional approach intended to reduce the urinary supersaturation associated with struvite and calcium oxalate formation.
This helps support urinary crystal risk management.
7. Reduced Magnesium Content
Magnesium is one of the mineral components involved in struvite stone formation.
Royal Canin Urinary S/O contains a controlled, reduced magnesium level as part of its urinary nutritional profile.
This helps support the formula's role in struvite management.
8. Optimised Mineral Balance
Urinary stone management involves more than controlling a single mineral.
Royal Canin Urinary S/O uses a carefully formulated mineral profile to support its urinary nutritional purpose.
The exact mineral concentrations should be verified against the current product packaging.
9. Complete Nutrition for Adult Cats
Royal Canin Urinary S/O is described as a complete veterinary diet.
It provides the nutrients needed for adult cat maintenance while delivering its specialised urinary nutritional benefits.
The duration of feeding should be determined by your veterinarian.
10. Convenient 1.5kg Packaging
The 1.5kg bag is a practical format for cats following a prescribed urinary diet.
It allows owners to maintain a consistent feeding routine while monitoring food intake and following veterinary recommendations.

Important Veterinary Feeding Recommendations
Use Only After Veterinary Assessment
Urinary symptoms such as frequent urination, straining, blood in urine, or urinating outside the litter box can have several causes.
A veterinarian should assess the condition before recommending a urinary diet.
Maintain Consistent Feeding
For a therapeutic urinary diet to work as intended, your cat may need to eat the prescribed food exclusively.
Other foods or treats can change the nutritional balance of the diet.
Follow your veterinarian's instructions regarding exclusive feeding.
Encourage Water Intake
Adequate water intake is an important part of urinary health management.
Provide fresh water in accessible locations and ask your veterinarian whether compatible wet food is appropriate.
Monitor Urinary Behaviour
Watch for changes in:
- Urination frequency.
- Urine volume.
- Straining or discomfort.
- Blood in urine.
- Litter box behaviour.
- Appetite and general activity.
Emergency Warning: A cat that repeatedly strains to urinate but produces little or no urine may have a urinary blockage. This is a medical emergency requiring immediate veterinary care, particularly in male cats. Do not wait for a dietary change to help.
