Query: Cats can play by themselves!

I ordered one of these for $2.30 and free shipping with Amazon Prime - I figured, what the heck, try it out... I have 3 cats, two of them being about 7 months old, and one of them 3 months old. All of them are NUTS over this toy. I have to admit, I was a bit "underwhelmed" when I opened the package - a wire with some twisted cardboard on it...? But, my kids play with the boxes their toys came in - the cats aren't any different! For awhile, I would hold the wire myself and wobble it around. Then I got the idea of fastening one end to a wrought iron baker's rack by weaving it through the wire designs and bending it out and away from the rack. Now the cats bat it around by themselves when I'm doing other things - I can hear the "BOING" of the wire against the rack all day long - they wear themselves out!! I've ordered 3 more of these to attach to their tree/condo! Fun stuff!
