Making a Petmate Crazy Circle Cat Toy?

I would like to know how to make a copycat of the Petmate Crazy Circle cat toy.

I would like to try to make one of these toys where there is a ball in a circle and the cat tries to bat it around and get it out. They have it at the stores from Petmate. Does anyone know how I can make an inexpensive one using ordinary objects that you can find around the house?
