i finally remembered to post this thanks to a thread.
there have been some times when a large python or boa might will constrict their owner for some reason.normally i know that alcohol would(or so they say it does) or hot water would get the snake to release. well i saw this snake show on a channel(cant remember where) and it said that if you twist back the tail of a LARGE python (boa as well?), that the snake will quickly release its grip. is this true?
