well if most of u are like any other snake owner and like to let ur python out for a lil run and to check things out, he/or she is gonna get stressed due to the same surrounndings all the time. if u handle ur snake alot and let it out alot the chances of trying to escape are more then if u dont let him out. thus creating stress. they get use to getting out and ppl tend to get side tracked and not let him out so they get stressed..who wouldnt. i let him out quite frequently and handle him alot and he seems to love the attention.. i can take him all ove and he'll stay on my wrist content to be out in the fresh air but u can bet the moment i put him away he gets antsy and wants back out but settles after a bit...he tries to escape but that will never happen due to small clamps on the lid....one thing ive noticed is that pythons like ppl are not the same. one thing can stess a 1 python and the same thing wont stess another python. thats where the owner has to pay attention and notice these things and learn their pythons wants and needs...
