I have a female red tail boa that I got about a year ago (she was a couple months old). She is getting big quick, and is already eating a Medium rat once a week. She has been very laid back up until about a week ago.

During the last week she has been sitting on top of her hide in constant "strike mode." I just fed her a nice fat rat a couple days ago, and she is still thick from that rat so I know she is not being underfed. Just now I walked past her tank and she struck and nailed the glass with her face!

What do you think is causing this sudden change? I am worried because she is going to be my one BIG snake and I don't want her to be nasty!!!!

Please help.
