Last night I was handling my gecko and he was acting normal and calm. Then suddenly he swung around and bit my finger really hard. This wasn't one of those fust a few teeth mark bites he drew a fair amount of blood. It was still gushing out blood 10 minutes after my bite and it still stings. I've been bit by full grown green tree pythons but i never expected this out of my very calm male leo. It was worse than when I got bit by an 16 inch plated lizard which was twice as big as him. Wow do leos have powerful jaws.
