The breeder had been feeding him frozen - thawed mice since he has quite a few snakes, he found this to work best. When I got Arnie he did not accept the first frozen - thawed mouse I offered him a week after I got him. I decided to try a live one and he ate it. That was a week ago tomorrow. Of course I now know not to leave the mouse in with him un attended just in case the mouse was to go on the offensive and bite him, but last week I did leave them together in a big plastic tub for a few hours and he ate the mouse while in there. Tomorrow night I will put the tub in the livingroom and keep a close eye while watching tv. I do not want to feed him in his cage so I will do it this way.
