A Pet Mouse

My roommate raise a pet mouse, she's name is LuLu. She is very cute and vigorous, when someone is near to her, she will rush to the direction where the person is and make some noise in order to let the person notice her. But most of times she just sleep, she even can sleep for a long time, maybe whole afternoon. I observe her sometimes and also I find more interesting thing about her. When she sleeping, her posture is very funny and unbelieve.

Look at these pictures.

I think she is the only mouse can do this, she is really interesting!
