Megacolon is a result of unrelieved constipation in cats. The only cure is surgery, in cats well enough to withstand such invasive procedures. x rays can also help diagnose arthritis. Arthritis can cause constipation, because it hurts the kitty to squat and hold such a position for too long. Because it hurts, kitty avoids going, and the poop builds up, becomes impacted, and (again) eventually forms a megacolon. Cosequin for cats can help with arthritis pain.
