You've got to love boas. They are great handling snakes; inquisitive but not darty and very confident.
Nice looking boa there. If you haven't noticed yet, boas tend to have a very strong food response.
If you haven't, I would start hook training. Don't want to be confused with a rat as she grows.
Any questions on hook training, general boa stuff, etc., just ask. There are quite a few boa peeps on here who will be happy to help.
Good luck and keep us posted.
