the only bite i've ever gotten was from my rosy boa.
the previous owner told me she had been aggressive, so i was cautious the first day.
nothing.
no hissing, no strike position, no aggressiveness at all.
so, i disregarded what i had been told. we fed her the next day, and she took the mouse no problem. i waited a few days, then got ready to take her out again. she was sleeping, but i just grabbed her anyways, she had acted like a ball python before...
the instant my fingers came into contact with her, she latched onto my thumb. she let go without too much prompting, and i washed the bite. the puncture wounds were healed within an hour.
