I definitely don't want to point a laser pointer to my cat, or somewhere he looks at. It is so bright, after couple of minutes, their eyes (much more sensitive than ours) must be hurt. And what if the cat realizes that the source of the light is the robot and look directly to the pointer? When I wasn't thinking of the brightness of the laser and tried to entertain my cat with it, after a minute, he realized it was me who control the pointer and jump to my lap, sniffed the pointer then lost its interest (well it is an Angora cat, one of the most intelligent cats in the world). If a cat does the same thing to the robot, it might harm its eyes.

Good idea, but the laser pointer must be replaced with a flash light or something less harmful.
