Another boa rescued

[Hayezoo]

Hey guys, just thought I'd post about the boa I recently rescued. Typical son goes to college, leaves snake, parents call me because they dont want it anymore....... I have rescued a couple of boas now ( not including this recent one ) but nothing could have prepared me for this one. Upon going inot the tank to get her, she opened her mouth quite wide and proceeded to hiss loudly. I have never seen a boa do this in person before. I mean, this was like my gopher snake!!! Anyway, the snake was obviously never handled, however, they were feeding it. Adult mice and small rats. She is QUITE capable of handling a large rat. No problem . I guess the mother didnt like rats, even thought they were frozen. The physical health of the snake is immaculate, we are just trying to calm her down a bit and get her used to being handled. I am aware this will take a while. Another reason I am posting is to see if anyone can help me as to what kind she is, I am having a little trouble. Any guess is appreciated, although I'm sure some of you out there will not need to guess. I will try my best to cover every angle of her, although she is a grumpy girl, I do not want to stress her. Thanks guys
