She has not tried splitting the skull that I know of. She may have, but I'm not sure. She did get him to eat the tail of something. I think it was a lizard, though, and not a mouse. He didn't care. He ate it, but has had no more enthusiasm about eating than before he tasted it. She has tried live and dead mice and lizards. She's tried house geckos, fence lizards, other random stuff. The darn thing just won't eat! It's really frustrating to me and it's not even my snake. -lol- I told her not to buy it (we knew it hadn't fed yet) but she fell in love with THAT one and had to have THAT one . -lol- She's really trying her best with it though. She's done everything she can, and she's doing a good job really. Gotta commend her for that. If it reaches that 3 month mark and still hasn't eaten, she says she's going to force feed it. She's trying to hold off though.
