I'm not sure about keeping it, the kids want it and the mouse sure is sweet right now. She likes to be cuddled in your hand and she soon falls asleep.
I always worry about the viruses they carry and am a huge "wash your hands" freak. I worry about her escaping too, I would hate that to happen. So I'm undecided as of yet.
She has lots of hiding places in the aquarium and different fabric choices along with some wood shavings to explore for now to keep her happy and entertained.
She's eating and drinking just fine too by the way!
