I wouldnt worry about it at all, mine to this too sometimes, you'll probably find that she does come out...but its when your sleeping.I used to think mine never came out of their hides but after I started getting used to the noises...I could hear them out and about in their vivs or if you get up through the night and turn the light on, you'll probably see her freeze in mid move and put a guilty face on. She'll probably be more lively after shed too...because then she'll be hungry,
