well, for the past two weeks, i'v been having a little bit of a problem getting lennie to feed. after presenting, he seems to be very interested in striking, but never really hunts for the rat and waits in ambush. while i know this is perfectly normal and expected, it gets odd when he never springs the trap. the slightest shadow moving in the room causes him to withdraw for a short time. this is a departure from a few months ago where the rat coming anywhere near the entrance to his hide yielded a swift death. it seems that even the rat exploring the tank in enough to startle him on occasion. could this be a behavior i should address further, or do i just have a picky snake?
