Key Clinical Benefits
- Struvite Dissolution & Prevention: It achieves a low Relative Supersaturation (RSS) index of <1 for struvite to promote rapid dissolution of stones and restrict future crystal buildup.
- Urine pH Optimization: The recipe maintains an optimal, slightly acidic urinary pH (typically between 6.0 and 6.5) to discourage crystal formation.
- Promotes Hydration: Formulated with high protein (44%) and adjusted sodium levels, it naturally stimulates your cat’s thirst, increasing urine volume and flushing the bladder regularly.
- Restricted Mineral Building Blocks: Features tightly controlled, low levels of calcium, magnesium, and phosphorus to remove the core elements that form stones.
- High Protein, Low Carbohydrate: Composed of 44% protein (mostly from animal sources) and 23% carbohydrates to match a cat’s natural carnivorous needs and help maintain an ideal weight.
- Allergen-Conscious Formula: It is entirely free from common food allergens such as wheat, gluten, maize, soy, egg, beef, or fish.
Primary Composition & Ingredients
As detailed by Virbac, the core components include:
- Potato starch
- Animal fats & minerals
- Lignocellulose, rice, and beet pulp
- Special additives: Omega-3 fatty acids (EPA + DHA) to reduce urinary tract inflammation, Chitosan to bind phosphate, and Lactobacillus acidophilus prebiotics for digestive support.
Guidelines & Best Practices
- Strict Dietary Compliance: Do not feed your cat any treats, human food, or alternative kibble during the treatment phase. Feeding external foods can alkalinize the urine or introduce raw minerals, completely halting the dissolution process.
- Maximize Fresh Water: Place multiple fresh water sources around the house. Investing in a water fountain is highly recommended to encourage the heavy drinking required to flush out the urinary tract.
- Veterinary Supervision Required: Because this is a medicalized clinical diet, you should only feed it under the guidance of a vet. Once the stones are confirmed dissolved via x-ray or urinalysis, your vet may recommend transitioning to a maintenance diet like Virbac Urology Urinary WIB for long-term management.
