Urinary obstruction is a dire medical emergency where the urethra becomes blocked, preventing the animal from urinating. This is most common in male cats due to their anatomy. The blockage leads to a rapid buildup of toxins in the blood, particularly potassium, which can stop the heart.
This condition requires veterinary attention.
If your animal shows the Key or Common signs listed, please visit a clinic immediately. This is a life-threatening emergency.
Report Case / Get HelpThis condition is not contagious. It is often the result of Feline Idiopathic Cystitis (FIC), crystalline debris, or bladder stones forming physical plugs.
Initial signs include frequent trips to the litter box and straining. This rapidly progresses to complete inability to urinate, vomiting, and extreme lethargy. Without treatment, death from uremic poisoning or cardiac arrest occurs within 24-48 hours.
Diagnosis is confirmed by physical examination revealing a large, hard, painful bladder that cannot be expressed. Blood work often shows elevated kidney values and dangerous hyperkalemia.
Standard treatment involves emergency sedation and catheterization to relieve the obstruction and flush the bladder. IV fluids are essential to correct electrolyte imbalances. Recurrent cases may require Perineal Urethrostomy (PU) surgery to widen the urinary opening.
Prevention focuses on increasing water intake, using urinary-specific diets, and reducing environmental stress. Weight management is also beneficial.
The prognosis is good with immediate treatment, but survival depends on kidney function. The condition can recur without longterm environmental and dietary management.
