wow, i would be pretty cranky to. i get pretty nasty on a rainy day when i have to stay inside my home let alone a box for 4 days. poor little guy. keep those temps right on like daniel said and give him lots of time to settle in. i cant stress enough that he has hides in his home. try a trick that i was told about on this forum that seemed to help my bp get used to his new suroundings. take paper balls and have them all over the cage so that the snake has something to crawl through when venturing out to drink, or switch hides. it diffenetly wont hurt. good luck
