I had a similar thing a few weeks ago but without the biting. This Jill was working a big warren, and when she came out of one of the holes, I picked her up to move her to another. She screamed this horrendous sound as if she was in pain, so much so that I instinctively let her go. I wondered if she had an illness, or was in pain, but I have since examined her and she appears fine.
I can only think it was a protest at havin been picked up, but I am really not sure. She never did it again that day, or, since.
