I'll try to make this short (I tend to ramble). How do you know what size of animal to feed your BP? I thought it was done by body size (just slightly smaller than the biggest part of the body). Pet store guy says to go by head size. I can't imagine feeding a full grown bp a mouse the size of his head. My bp is still young, but i knew fuzzies wheren't cutting it. I asked for the next size up, but he said a hopper was too big. I just gave him two fuzzies, which he took with a quickness. I trust this forum over a pet store guy, no matter how many snakes he has. Let me know how you determine food size. I do think two fuzzies will cut it for now. I just want to know when to upgrade. I don't want baby bp getting hungry. lol.
