Switching Ball Python to f/t mice?

[Cmwells90]

Cage defense is normal, I hook train my snakes and it makes life a LOT easier. I just tap my boa on the head with the snake hook when I'm ready to take her out, it lets her know she's not being fed she's being handled, and I can see an immediate change in behavior. I think it's a good thing for a snake to be defensive, it's a natural behavior, but once they're on the hook they calm down a lot, usually! Remember, he doesn't know you're friendly, he just knows your big and could hurt him, so he's ready to defend himself if needed. Also, have you been measuring his weight or is the "skinner" look just a sight determination?
