feed him more than once a week. i recommend offering food every four days, and don't skimp on the mice. he should have a nice bulge after feeding.

make sure he has a nice thermal gradient. high 80's on one end and low 70's on the other. if he's too hot he'll be a problem for you since he's uncomfortable and has nowhere to go to get away from it (lampros like having a nice cool area - i use moist moss hides for them).

if he's spending a lot of time on the hot end, it could be because it's his only choice for a good hide.

then, handle him lightly two days after feeding (to ensure he's digested). he'll eventually get used to being handled. but make sure you're feeding him enough and has an area to get out of the heat. and don't forget to wash your hands before handling him, getula are chow hounds. heck, i've even seen one try to eat a cat
