Urethral obstruction is a life-threatening emergency in male cats, causing severe pain and rapid deterioration that requires immediate veterinary intervention.
Urethral obstruction causes intense suffering: bladder distension is exquisitely painful, and rapidly developing uraemia causes nausea, cardiovascular compromise, and deteriorating mentation. The welfare urgency cannot be overstated — every hour of delay worsens outcomes. Even following successful catheterisation, cats face significant discomfort during recovery and are at risk of recurrence. Long-term management with increased water intake, dietary modification, and stress reduction is essential. Male cats from the age of 1 year, particularly those fed dry diets with limited water access, are at highest risk. Recognising straining to urinate as a potential emergency, not simply constipation, is critical welfare knowledge for cat owners.
