I can attest to the inexorable power of the laser pointer as a cat toy with at least one of my cats. I think now his whole life is defined as the times between when he gets to follow the red dot around the house. The best thing about it is that you can shoot it all over the room without moving, so your own motion does not distract the cat from running about like a maniac. And you can make them spin in place until they're dizzy. It's probably mean but it's funny to see a dizzy cat.

Now, though, we fear that all other cat toys will lose their appeal. For now, though, the string seems to still work.
