Also, I agree with your observation about redness looking like blood. She did not or was not bleeding at all. I soaked her and had her under some warm water. By gently "carressing" her, the piece of what appeared to be shed came off, and this spot remained. I did not pick or yank any skin off of her. I placed a tissue on the area to check for fluid of any type, and she had no red or clear fluid coming off of the area. The "tackiness" I first described is gone, the area now feels like the skin on the rest of her, but it sure does not look the same!! Her appetite and attitude has not been changed at all. She is still very calm and does not mind handling. She ate the night after this happened, and is wanting another rat today.
