I have never seen that one.

May I suggest a toy that works like a charm? I bought mine the "talk to me treatball" on Dr.FosterSmith website, and you can record YOUR OWN message on it. It holds the treats inside (I use Katcheese treats) and when they bat it your message plays and they have to keep batting it around, and about every 6 bats or so, a treat comes out. I LOVE IT! And the cats love it too. They like it without the treats, but esp. with them It works well for my overweight cats, because they need motivation to play.
