Exercising a Cat and Wikipatents

While searching for IC's I came across this:
http://www.wikipatents.com/

Looks like a site for the public to comment on patents.
Maybe...
Comments like "You ***..you stole my idea!" :)
Or....
You can ridicule patent 5443036: Using a laser pointer to
exercise your cat.
Geeeezz....

One of the lamest patents I know of.

Why would somebody patent that?
