Cat Megacolon Welfare and Management

Megacolon causes severe constipation and welfare harm in affected cats requiring medical or surgical management.

Key Facts

Megacolon is colonic dilation with loss of smooth muscle function causing obstipation
Affected cats strain unproductively and can become dangerously debilitated from faecal toxaemia
Medical management includes dietary modification, lactulose and periodic enemas
Subtotal colectomy is a curative surgical option achieving excellent long-term welfare outcomes in most cases
Idiopathic megacolon, pelvic fractures and neurological disease are the primary causes

Welfare Considerations

Megacolon causes severe discomfort from persistent constipation and toxaemia. Medical management provides relief for early cases. Surgical subtotal colectomy offers excellent long-term welfare outcomes for cats with established megacolon who are appropriate surgical candidates.

What You Can Do

Seek veterinary assessment for cats with chronic constipation before megacolon develops
Discuss surgical colectomy options with a specialist for cats with established megacolon
Implement dietary management including psyllium fibre and lactulose for cats with early constipation
