Hello everyone, I just got my little guy this morning. He's a Hog Island Boa. I decided to get a Boa over a Ball Python for my first reptile, because Boas have better personalities in my opinion and better eating attitudes. I have a few questions I would hope you guys can answer.

1-Why does my boy keep trying to escape his enclosure ? It seems like he wants to get out so badly.
2-Why doesn't he use his hide and heat pad ? I don't know if Boas really use hides, like BP's do but I would assume since he's new he would want to be in his hide until he gets used to the environment.
3-How do I get the proper humidity levels ? I don't have substrate yet, I'm just using paper towel for now. I guess I should spray the tank down.
4-When should I feed the guy ? It looks like he ate recently, or I could just be seeing things. I was going to try feeding him next Sunday. Is that ok ?
5-In his tank so far it's ver barebones. I have a hide above his heating pad and a water dish. I will pick up some supplies after work tomorrow. I was going to get some ReptiBark for my substrate, another hide to place on the cool side (Don't know if this is truly necessary since he doesn't even use his main hide), and some branches or logs for him to climb. Anything else ya'll would recommend ?

And here's some pictures of him. His name is King.
