Does your friend have other pets at home that maybe your snake can smell on him? They have an extremely good sense of smell. But BPs often rely a lot on their
heat-sensing pits...maybe his bigger arms are giving off more heat? (& are you one of those folks that's always cold?) Or maybe he smells "natural" while you & your
gf use scented soaps that deter the snake? Your BP shouldn't be trying to eat ANY humans, so I dunno...?I guess he tastes better, LOL.
