Tried this on two cats in different houses. Both of them looked at it, looked at me, looked at it, hit the ball, looked at me, looked at it, looked at me, and said, "WTF?" and walked away, never to touch it again. Enough said. YMMV but for me, waste of money. I tried to find it cheaper at Big Lots like another reviewer said but could not so $14 down the drain. Too much hassle to return.
