Rosie's been acting up lately.

I got her around Christmas and either mom or I have been handling her everyday since. Lately, though, she's been striking at the glass whenever someone even looks her way. A few minutes ago I was looking at her and she struck about four times and then just sat there with her mouth open hissing at me. Last night she bit me. Not a big deal, but it's all happened very suddenly. Very docile, then very aggressive.

She ate a mouse every week fine, but this week we moved her to two mice.
Temps are fine. 80ish ambient, 90ish basking.
Two hides.
UTH and infared heat bulb.
10 gallon tank. [looking to upgrade in the next month or so.]

I'm getting more and more scared of her as the days pass.. I don't want to get rid of her, so if anyone has any experience with this.. help?
