So to revive this thread with some updates:
She's now eating rats, so eating isn't an issue at all.
However she's still making that squeaking noise. I recorded a quick video(cell phone quality, but it should get the point across) and for the first minute and a half, she's quiet, but around 1:40 she starts the squeaking noise (you'll need the volume up high).

What is this and is it bad? Or is that just her saying put me in my tank, I'm done playing?
