Does your cat like to chase the laser pointer? A couple of my dogs do, and it sends them in a running frenzy around the house, trying to catch that pesky little dot.
With the marvels of new technology, you don't even have to hold the laser pointer anymore; there's a new video game for cats. I don't have a cat at the moment, but I think I'll download it anyway and see if my dogs want to play. :-)
