Patent Number: 5443036
Method of exercising a cat In 1993 the USPTO issued this patent for using a laser pointer to exercise a cat (yes, by moving the laser pointer beam around and having the cat chase it). Come on now... Not only is this crazy to patent, but this idea had surely been thought of long before this patent came about. In fact, a bit of research turned up the book "One Hundred and Eighty-Seven Ways to Amuse a Bored Cat" (Ballantine Books; May, 1982) that describes the exact same idea, but using a flashlight.
