Critical Veterinary Warning: Recognizing FLUTD & Urinary Blockage in Cats

Urinary obstruction is a life-threatening medical emergency, particularly in male cats. Pet parents should seek immediate veterinary attention if any of the following symptoms appear:

• Frequent trips to the litter box with little to no urine produced.

• Straining, crying, or vocalizing while attempting to urinate (often mistaken for constipation).

• Hematuria (pink, brown, or blood-tinged urine droplets).

• Urinating outside the litter box on cool, smooth surfaces (tiles, sinks, bathtubs).

• Constant, excessive licking of the genital and perineal region.

• Lethargy, abdominal rigidity, hiding behavior, or sudden vomiting.

Clinical Veterinary Indications

• Nutritional dissolution of sterile struvite (magnesium ammonium phosphate) bladder stones and crystals.

• Long-term dietary prevention of recurrent feline struvite urolithiasis.

• Nutritional management of Feline Lower Urinary Tract Disease (FLUTD) and Feline Idiopathic Cystitis (FIC).

• Management of cats showing painful dysuria, stranguria, or hematuria.

• Daily maintenance diet for adult cats predisposed to crystal formation or low voluntary water intake.

Feeding Guidelines & Transition Protocol

Divide daily allowances into 2 to 3 small meals. Adequate water intake is essential for urinary dilution—place multiple fresh water bowls or water fountains around the house:

7 to 10-Day Gradual Transition Schedule (Mandatory):

• Days 1–2: 25% PetStar Struvite Diet + 75% Current Cat Food

• Days 3–4: 50% PetStar Struvite Diet + 50% Current Cat Food

• Days 5–6: 75% PetStar Struvite Diet + 25% Current Cat Food

• Day 7–10 Onward: 100% Mankind PetStar V Diet Struvite (S&O)

Safety Warnings, Precautions & Contraindications

• Struvite vs. Non-Struvite Diagnosis: Formulated specifically to manage struvite uroliths via urine acidification. Contraindicated in cats with Calcium Oxalate, Ammonium Urate, or Cystine uroliths, or in cats suffering from metabolic acidosis or severe hepatic disease. A urinalysis should confirm struvite crystals before long-term use.

• Kitten & Breeding Precaution: Not recommended for growing kittens, pregnant queens, or lactating mothers requiring high-calcium, non-acidifying diets.

• Do Not Combine with Urinary Acidifiers: Do not co-administer with concurrent veterinary urine-acidifying medications (such as ammonium chloride or supplemental methionine), as excessive acidification can induce metabolic acidosis or promote calcium oxalate stone formation.

• Storage Instructions: Store in a cool, dry place away from direct moisture and sunlight. Reseal the package securely after each feeding or store in an airtight container to keep kibble fresh and protect active omega oils from oxidation. Keep out of reach of children and domestic pets.
