Urinary Blockage (Signs)

A urinary blockage (urethral obstruction) prevents urine from leaving the bladder. This is a life-threatening emergency, particularly common in male cats but can occur in dogs too. Toxins build up rapidly, leading to kidney failure, bladder rupture, and death if not treated urgently.

Recognising the Emergency Signs:

• Straining to urinate with little or no urine produced
• Frequent attempts to urinate (in litter box or outdoors)
• Vocalising (crying, howling) during urination attempts
• Licking genitals excessively
• Restlessness, agitation, pacing
• Hiding
• Lethargy, weakness
• Vomiting
• Loss of appetite
• Abdominal pain or distension (hard bladder felt)
• Collapse

Why it's an Emergency:

• Urine backs up into kidneys causing severe damage.
• Electrolyte imbalances affect heart function.
• Bladder can rupture.
• Toxin buildup leads to coma and death, often within 24-48 hours.

First Aid Action:

1. Recognise the signs.
2. Seek IMMEDIATE emergency veterinary care. Call ahead to confirm they can treat emergencies and let them know you suspect a blockage.
3. There is NO effective home treatment. Do NOT press on the bladder. Do NOT delay seeking professional help.
