Hi Kendall,
Cats Eyes invented by a bloke named Percy Shaw, lived other side of a big hill near where I grew up.
Story goes that he was driving on the road up the side of the hill - narrow road, steep drop down one side to valley below, no street lighting - pretty dangerous really. Still a bit hairy today on an icy evening.
Anyway. Story goes, he was driving up the road one night, taking great care to stay on the road and not plummet down the hill, when a cat crossed his path. He could see the light from his headlights reflected by the eye of the cat shining bright in the darkness. That gave him the idea for the reflecting road studs.

They reckon that if the cat had been facing the other way round he would have invented the pencil sharpener...

Quack!
GtD.
