When to see a vet
This is not veterinary advice. If red flags appear (open-mouth breathing, months of weight loss, 'stargazing', persistent regurgitation) consult a qualified exotic (herp) veterinarian. Quarantine new arrivals 30–90 days.
Good to know
- Named for its loud 'TO-KAY!' territorial call.
- One of the largest geckos — and in parts of Asia a symbol of good luck.
- Grips so strongly it can hang from glass by a single toe.
Common questions
Can I handle it?
Not really — it bites hard; a display species.
Why is it so loud?
A territorial call — completely normal.
Wild-caught okay?
Prefer captive-bred — health & conservation.
