I arrived at work this morning to find our cat sitting, just outside one of the doors with a mouse in her mouth. When she dropped it the mouse started to run around, with her patting it from side to side like she was playing with a ball. Then she would catch it and hold it in her mouth again. This was repeated several times. Eventually we got the mouse away from her took it outside and let it go. She seems to like to show us how she can catch and control the movements of the mice.
