I have a 3200 gram female het pied that I had traded a boa for a little over a year ago. She is everything but a pet lol. The Idiot I got her from thought it was funny to Push his four arm in her face until she would bite him to show people that it doesn't hurt. Well it seems like (in her mind) anytime you open her cage she needs to bite in order for you to leave her alone. It gets fun trying to get her out of her cage for cleaning time. Its the only time I ever mess with her because you can tell she gets really stressed out when you open her tank. She likes to be left alone so I leave her be as much as I can.
