A urethral obstruction — commonly called a 'blocked cat' — is the most common life-threatening emergency in male cats. Crystals, mucus plugs, or bladder stones lodge in the narrow male urethra, preventing urination. The bladder distends painfully, toxins build up in the bloodstream, and without emergency treatment, the bladder can rupture or the cat dies from hyperkalemia (elevated potassium stopping the heart) within 24-48 hours.

Emergency Signs (Can't Pee = Emergency)

  • Straining in the litter box — repeatedly going in and out, posturing to urinate but producing nothing or only a few drops
  • Vocalizing/crying while trying to urinate — this is PAIN, not constipation
  • Licking genitals excessively
  • Hiding, lethargy, vomiting — late-stage signs indicating toxin buildup
  • Firm, distended bladder (feels like a tennis ball in the lower abdomen)
  • Collapse or unconsciousness — imminent death, get to ER immediately

What Happens at the Vet

Emergency unblocking requires sedation/anesthesia, placement of a urinary catheter to flush out the obstruction, and 2-4 days of hospitalization with IV fluids. The cat goes home with pain medication, urethral relaxants, and typically a prescription urinary diet (Hill's c/d, Royal Canin Urinary SO, or Purina UR).

Treatment Cost

Emergency unblocking + 2-3 day hospitalization: $1,500-$3,500. If the blockage recurs (15-25% do within 6 months), perineal urethrostomy (PU surgery to create a wider opening): $3,000-$6,000. Prescription urinary diet: $50-$80/month — lifelong, non-negotiable. Pet insurance typically covers urinary blockages if not pre-existing.
