VIRBAC UROLOGY URINARY WIB 1.5KG

Virbac HPM — Cat Urology Urinary WIB | 400g / 1.5kg | Veterinary Clinical Dry Cat Food

The urinary diet that protects against both crystal types. Virbac HPM Cat Urology Urinary WIB is a veterinary clinical nutrition dry cat food specifically formulated to support feline urinary health — preventing and managing the full spectrum of feline lower urinary tract disease (FLUTD), including struvite crystals, calcium oxalate crystals, idiopathic cystitis, and urethral plugs. The “WIB” designation reflects the most clinically sophisticated aspect of this formula — a precisely balanced mineral profile that simultaneously prevents struvite crystal formation and calcium oxalate crystal formation, the two most common urinary crystal types in cats. Most urinary diets address one crystal type effectively but inadvertently promote the other — acidifying diets dissolve struvite but increase calcium oxalate risk; alkalizing diets prevent calcium oxalate but promote struvite. Virbac HPM Urinary WIB navigates this clinical tension through precise mineral balance, controlled pH targeting, and high moisture encouragement — protecting the entire urinary tract without compromising against either crystal type. Available in 400g (trial size) and 1.5kg.

Why Virbac HPM Cat Urology Urinary WIB Is The Best Choice

• Dual Crystal Protection — Struvite & Calcium Oxalate — The WIB formula simultaneously prevents both struvite and calcium oxalate crystal formation — the most clinically complete urinary protection available in a single diet.
• Balanced Mineral Profile — Precisely controlled magnesium, calcium, phosphorus, and sodium levels — reducing the mineral concentrations that drive crystal formation without creating the imbalances that promote the opposite crystal type.
• Optimal Urine pH Targeting — Targets a urine pH range that is unfavorable for both struvite (alkaline) and calcium oxalate (acidic) crystal formation — the narrow pH window where both crystal types are minimized.
• High Moisture Encouragement — Formulated to encourage water intake and increase urine volume — diluting the mineral concentrations that drive crystal formation and reducing urine specific gravity.
• Struvite Dissolution Support — The formula supports the dissolution of existing struvite crystals and prevents new struvite formation — the most common crystal type in young to middle-aged cats.
• Calcium Oxalate Prevention — Prevents calcium oxalate crystal formation — the most common crystal type in older cats and the crystal type that cannot be dissolved by diet alone.
• Idiopathic Cystitis Support — Stress-reducing and anti-inflammatory nutritional support for cats with feline idiopathic cystitis (FIC) — the most common cause of FLUTD in young cats.
• High Palatability — Clinical urinary diets must be consumed consistently — the Virbac HPM formula is formulated for high palatability to ensure consistent daily consumption.
• Two Sizes — 400g trial size for initial introduction; 1.5kg for ongoing management.
• Virbac HPM — Veterinary Expertise — From one of the world’s leading animal health companies.

Product Details & Features

Understanding Feline Lower Urinary Tract Disease (FLUTD) FLUTD is an umbrella term for a group of conditions affecting the bladder and urethra of cats — and it is one of the most common reasons cats are presented to veterinarians. Understanding the spectrum of FLUTD conditions explains why the WIB formula’s comprehensive approach is clinically superior to single-indication urinary diets: Prevalence:

• FLUTD affects approximately 1–3% of cats annually
• Recurrence rates are high — 30–50% of cats experience recurrence within 12 months without dietary management
• Male cats are at significantly higher risk of urethral obstruction — a life-threatening emergency

The FLUTD spectrum: Feline idiopathic cystitis (FIC) — 55–65% of FLUTD cases: FIC is the most common cause of FLUTD in cats under 10 years — characterized by bladder inflammation without an identifiable cause. Stress is the primary trigger — environmental changes, multi-cat households, indoor confinement, and routine disruption all increase FIC risk. Clinical signs include straining to urinate, blood in urine, frequent urination of small amounts, and urinating outside the litter box. Struvite crystals/uroliths — 15–20% of FLUTD cases: Struvite (magnesium ammonium phosphate) crystals form in alkaline urine with high magnesium and phosphorus concentrations. They are the most common crystal type in young to middle-aged cats and can be dissolved by dietary acidification and mineral restriction. Calcium oxalate crystals/uroliths — 10–15% of FLUTD cases: Calcium oxalate crystals form in acidic urine with high calcium and oxalate concentrations. They are the most common crystal type in older cats (>7 years) and cannot be dissolved by diet — they require surgical or interventional removal. Prevention is the only dietary strategy. Urethral plugs — 10–20% of FLUTD cases: Urethral plugs are accumulations of crystalline material, inflammatory debris, and mucus that obstruct the urethra — primarily in male cats. Urethral obstruction is a life-threatening emergency requiring immediate veterinary intervention. The WIB Clinical Strategy — Dual Crystal Prevention The fundamental tension in urinary diets: Most commercial urinary diets are formulated primarily for struvite prevention — they acidify urine and restrict magnesium. This approach is effective for struvite but creates a clinical problem:

• Acidic urine promotes calcium oxalate crystal formation — the calcium and oxalate ions are more soluble in alkaline urine and precipitate more readily in acidic urine
• Struvite prevention diets that over-acidify urine increase calcium oxalate risk — particularly in older cats who are already at higher calcium oxalate risk

The WIB (Well-balanced, Integrated, Balanced — or the Virbac HPM designation for their dual-protection urinary formula) approach resolves this tension: Optimal pH targeting: Research has established a urine pH range of approximately 6.2–6.8 that is:

• Sufficiently acidic to prevent struvite crystal formation (which requires alkaline pH >7.0)
• Sufficiently alkaline to minimize calcium oxalate crystal formation (which is promoted by acidic pH <6.0)

The WIB formula targets this narrow optimal pH window — providing struvite prevention without the over-acidification that promotes calcium oxalate. Balanced mineral profile: The mineral balance in the WIB formula is precisely calibrated: Magnesium restriction:

• Magnesium is a component of struvite crystals — restriction reduces struvite formation risk
• Magnesium restriction must be balanced — excessive restriction can cause other metabolic issues

Calcium control:

• Calcium is a component of calcium oxalate crystals — controlled calcium intake reduces calcium oxalate formation risk
• Calcium must not be excessively restricted — adequate calcium is required for bone health and binds intestinal oxalate (reducing oxalate absorption)

Phosphorus control:

• Phosphorus is a component of struvite crystals — controlled phosphorus reduces struvite formation risk
• Phosphorus control also benefits cats with concurrent early kidney disease

Sodium — The Hydration Driver: Controlled sodium in urinary diets serves a specific purpose — mild sodium inclusion encourages water intake, increasing urine volume and diluting mineral concentrations. Dilute urine is the most effective protection against crystal formation of any type. High Moisture Encouragement — The Most Important Urinary Strategy Urine concentration (specific gravity) is the primary driver of crystal formation — concentrated urine has higher mineral concentrations that more readily reach the saturation point where crystals precipitate. Increasing urine volume through increased water intake is the most effective single intervention for urinary health:

• Dilute urine — Lower mineral concentrations reduce the risk of reaching crystal saturation
• Increased urine flow — More frequent urination flushes the bladder more regularly — reducing the time minerals have to accumulate and crystallize
• Reduced urine specific gravity — The target urine specific gravity for urinary health is <1.030 — ideally <1.025

The WIB formula encourages water intake through:

• Mild sodium inclusion — stimulating thirst
• High palatability — ensuring consistent consumption of the diet that supports hydration
• Veterinary recommendation to provide multiple fresh water sources and consider water fountains

Idiopathic Cystitis Support For the 55–65% of FLUTD cases caused by FIC, the WIB formula provides: Stress reduction through nutrition:

• Antioxidants reducing oxidative stress that exacerbates bladder inflammation
• Anti-inflammatory nutrients reducing the bladder wall inflammation that causes FIC symptoms
• High palatability reducing the feeding-related stress that can trigger FIC episodes

Bladder glycosaminoglycan support: The bladder wall is protected by a glycosaminoglycan (GAG) layer that prevents urine from irritating the bladder epithelium. In FIC, this GAG layer is compromised — allowing urine to contact and irritate the bladder wall. Nutritional support for GAG synthesis supports bladder wall integrity. Crystal Type by Age — Why Ongoing Prevention Matters The WIB formula’s dual protection is particularly valuable because:

• Young cats on struvite prevention diets age into the calcium oxalate risk period — the WIB formula provides continuous protection through both life stages
• Cats with a history of struvite crystals are not immune to calcium oxalate — both crystal types can occur in the same cat at different times

Urethral Obstruction — The Emergency Prevention Priority For male cats — who are at significantly higher risk of urethral obstruction due to their longer, narrower urethra — the WIB formula’s comprehensive crystal prevention is a potentially life-saving intervention:

• Urethral obstruction is a veterinary emergency — complete obstruction causes death within 24–48 hours without treatment
• Crystal-based urethral plugs are the most common cause of obstruction in male cats
• Preventing crystal formation through consistent dietary management is the most effective long-term strategy for reducing obstruction risk

Specifications & Feeding

Feeding Guidelines Divide daily amount into 2–3 meals. Always provide multiple sources of fresh water — a water fountain is strongly recommended for cats with urinary disease. Adjust based on body condition and veterinarian’s recommendation. Transition Guidelines Serving Tips

• Multiple fresh water sources — Provide 2–3 water bowls in different locations plus a water fountain — cats with urinary disease must drink more
• Wet food supplementation — Consider adding Toro or Sheba Premium wet food alongside the dry WIB diet — wet food’s high moisture content significantly increases daily water intake
• Consistent feeding — Feed at consistent times — urinary health benefits from regular, predictable feeding schedules
• No treats with high mineral content — Avoid treats with high magnesium, phosphorus, or calcium during urinary management
• Monitor litter box — Watch for signs of straining, blood in urine, or reduced urine output — these require immediate veterinary attention
• Male cats — emergency awareness — If a male cat strains to urinate without producing urine, this is a veterinary emergency — seek immediate care
