Mouse toy for cats

I wanted to make a hanging toy for my cats. The obvious shape would have been a mouse, and I liked SteedMaker's Pet Mouse. Just added a hole in the middle of the mouse model, so that I can push a string through the hole, make a knot at the bottom to prevent the mouse from falling, and tie the string to something tall enough for the mouse to swing in the air.

Instructions: push a string through the hole in the mouse back, hang it where your cats can play with it.
