My new guinea pig I just got from the pet store(Solo), is not coming out of her hiding place. She has not moved at all since I put her in the cage, which was 2 days ago she doesn't even move her head. Today to move her I had to pick her up, and put her in a box to see if I could get her to eat something. She kind of sniffs it, and then goes back to staying still. She also hasn't drank anything. Should I just leave her there for a few more days, or try other things.
