I have had my leo for over a year now I take him out like twice a week at the most and let him run up and down my arm and on my shirt for like 15 minutes at a time. As far as being bitten not by a leo but a tokay did and ask long as they get your whole finger and not just a little flap of skin its not bad. Like a little kid pinching you. getting bit by a mouse or something with real teeth hurt way worse.
