I had my BP for about two weeks and it already got loose. I had the lid duct taped closed. we went on vacation for a couple days and when we got home poof no snake. it only took me a min to find him, he was chilling on the bookshelve just hanging out. but then when i go to grab him he takes off like a mad man went into the damn heat radiator on the floor i was able to grab his tail and hold him until he backed out. it was scarry i thought he was a goner. good thing he made it out without a scratch. so now that lid is really secure so that wont happen any more. i read that the are escape artist but i guess i didnt know how strong they are.
