My cats just love the mouse inside the circular container. They get it to going around the circle and they love to bat at it. It doesn't go anywhere just stays inside the circle and goes round and round but they have never gotten bored with it.

They will stop playing for a few days but go back to it. The fur on the mouse's back is all worn off now. I've had it since I got my first kitty who is three now.

I've had to get rid of some toys they don't like anymore but they still like to play with this one.
