So I've got a pretty great conclusion to this.
Took about 30 seconds for me to convince her to heat a thawed hopper mouse. In retrospect, she probably could have taken bigger, but I can't complain!
Unfortunately I forgot to turn off my camera flash when I took the pic, but it didn't stop her from gulping it down. Think I was more stressed by the whole process than she was.
To reiterate, my juvenile, first-ever-owned BP, who was raised in a tub on live and is now in a tank setup with loud music and me hovering over her, ate frozen with no qualms.
I AM SO HAPPY!!!!!
