Cats can develop bladder stones due to dietary imbalance, poor water intake or urinary/bladder infection — with struvite crystals and calcium oxalate stones the most common types, causing considerable discomfort. Virbac Veterinary HPM U2 Dissolution & Prevention is a complete urinary-care dry diet that helps break up and eliminate struvite stones while also helping prevent new struvite and oxalate crystals from forming. Built on the HPM philosophy, it's a low-carbohydrate, high-protein formula (44% protein, of which 90% is animal-origin, and 23% carbohydrates) that encourages water intake and urine dilution. This is a therapeutic veterinary diet and should be used under veterinary supervision.
Key Benefits
-
Encourages hydration & urination — elevated high-quality protein (44%) encourages cats to drink and urinate more, helping flush out hard bladder deposits faster.
-
Low struvite RSS (<1) — analysed for a low relative supersaturation to help dissolve and prevent struvite bladder stones.
-
pH balance — helps balance urine pH to prevent both struvite and oxalate crystals returning.
-
Reduces urinary inflammation — a high level of omega-3 fatty acids (EPA + DHA) helps reduce lower urinary tract inflammation.
-
Mineral control — limits calcium and phosphate intake, and is low in carbohydrates, calcium, magnesium and phosphate to lower future stone risk; potassium citrate helps limit calcium oxalate crystal formation.
