I don't think that will ever happen.
just sayin'
I think no.
I don't think my snakes care who puts their hand in their encloures...just as long as they are fed.
Again...I ask you...If your snake recognizes you then why would he be gone if you left his enclosure open.
I know there are a rare few that believe that he would just look for your pillow and curl up but nah ah.
and....
why would he bite you if he was in shed...or hungry?
