Good fun, especially when you can 'encourage' the cat to do things it might otherwise think about... It might amuse you to know that someone actually has a patent (US at least) on it. "Method of Exercising a Cat" or some such. I think you had to move the laser around yourself though. Pretty old, might have expired by now.
