I just got bit last night and it was 110% my fault. got home after a long shift, it was late, and i hadnt slept well the night before.. I was cleaning out the rat cage, and without even thinking, i took out our adult male ball python to clean his enclosure, and i felt a pain in my wrist.. the snake had a good hold on my inner right wrist, punctured a few veins and proceded to constrict my hand for what I would guess to be about 30 seconds. he let go, i put him in a bag and washed off. the punctured veins made my wrist swell up nicely and now i've got a nice big bruise and a sore wrist.
a lesson definatly learned.
