i have not been bitten by my male, or known anyone chomped by their bp, but they feed by either dropping the prey (F/T) into a tall box and letting them snag it, or grabbing the prey with hemostats. i love the stats, because i can wiggle the mice around so that they look like they are alive. he will usually strike faster this way. However, be sure to do a few things when feeding. i feed Frozen and Thawed rodents, so some of this may not be neccessary if you fee prekilled or stunned. i personally recommend FT is at all possible.
Don't use your hands to feed. use tongs or hemostats.
Most animals react in fear towards an unknown object that is coming towards them. when you wiggle the FT, move it side to side in front of the snake, or away from it. They will respond to the "running away" motion as a chase, but since many snakes are head-shy, they may be afraid of the food item if you move it towards their head quickly, because it may be percieved as an attack.
Be careful where you put the prey, i know some snakes are so eager, they strike and hit their own bodies in thier eagerness to feed, and it seems to make them momentarily hesitant to strike again after realizing they are chomping their tail
Afterwards, they may have a feeding response if you don't let them calm down and realize they aren't getting more food. I don't know
exactly how long to let them be, but i give all my snakes about five to fifteen minutes after they finish swallowing to "cool down" so that they don't bite me mistaking me for prey. It may not be necessary, but i try to take as many precautions as possible. It helps if they are eating the right amount of food per meal, they are much calmer after a medium-large meal (appropriate for their size of course, not too big) than a "snack". besides, one feeding per week means fewer poops per week
which is a benefit for most... good luck, they are cool animals!
