US Patent Issued for Method of Exercising Your Cat - Use Laser Pointer
Joel IM'd me a link to a story about a US Patent that was issued for a method of exercising a cat. The patent claims that cats by nature are very hard to get to do any form of exercise, and by using a laser pointer you can overcome this natural lethargicness.
Here's some of the actual text from the patent:
A method for inducing cats to exercise consists of directing a beam of invisible light produced by a hand-held laser apparatus onto the floor or wall or other opaque surface in the vicinity of the cat, then moving the laser so as to cause the bright pattern of light to move in an irregular way fascinating to cats, and to any other animal with a chase instinct.
