i think any snake WILL try get through any hole they have access to,
i was feeding my BP Vale last night as usual in his feeding container which doesnt have holes drilled. since i always watch him feed, ( he never refused until last night ) ive never put the lid on. i put a p/k rat in, he seemed interested at first but then decided to ignore the rat and was more eager to get out. i then put the lid on and just slid a hanger between the lid and container for ventilation. as i was watching, he crawled up and managed to put his head thoough the round part of the hanger which is smaller than his girth ( he`s more than a year old ). as i tried to make him go backwards, he was more determined to get though it. i REALLY panicked, it was about 2am and i was thinking to myself how the hell am i going to get help at this time! luckily he did manage to slide through and it was actually with quite ease. i was really relieved and just sat down soaked wet with sweat. its incredible how they could get through small spaces/things.
