I used to have one. My cat loved it. But I primarily used it to agitate the pigeons that hung out in the Newkirk Av subway station in Brooklyn. They would always be pooping this way and that, so I fought back by pointing the laser pointer in their eyes. It was awesome. But alas, the on/off switch wore out from overuse. And now I am laser pointer-less. But I am always on the lookout for a new, cheap, one.
