Just watch her, hoppers have there eyes open and are pretty crazy some times. when i feed my BP them some times i have to remove them because they just have to much spunk and are off the wall. i think the one i had was nuts lol
Also, place the hide in a corner and the hopper in the opposite. if they cower in the corner even better non moving target for your BP. but like i said monitor it because some of them can be a lil crazy and if she gets spooked it will do more harm then good.
The mouse was pretty crazy, it wouldn't stop moving, and was just running all over the place trying to climb on everything. I'll probably go see if I can get a smaller live one that isn't so..active. hah.
