This is the best $2 I've spent on a cat toy

The Cat Dancer is a 30-inch piece of wire with some little cardboard cylinders on the end. My cats go crazy for it. I stuck it on the wall with the adhesive mount, but I ended up taking it off so I could hold it and play directly with my cats. That way they won't get bored as quickly. Now they start meowing when they see me take it out of the drawer. It's $2 on Amazon.
