Self-Mutilation

What is it?

Self-mutilation is when a sugar glider chews or bites its own body, most often the tail, legs, genitals, or a surgical site. Gliders are highly social, and stress from living alone, boredom, irregular schedules, or a poor environment is a frequent trigger. Pain, infection, parasites, and post-surgery irritation can also start it.

What signs should I watch for?

Signs to watch for include fur loss or bald patches; chewed tail tip or limbs; open, bleeding wounds; constant grooming of one area; and crying, restlessness, or irritability.

How is it diagnosed and treated?

Your veterinarian treats wounds, controls pain and infection, and may use a protective collar or bandage. The real work is finding the cause: checking for medical problems and reviewing housing, companionship, diet, and daily routine.

Can it be prevented, and what's the outlook?

  • This can become severe quickly and is an urgent problem.
  • Keeping gliders in compatible pairs or groups with a large, enriched cage greatly reduces risk.
