My cats think my SL is a purfect place to lounge, too.

Although I don't recommend you do it... Per Ohms Law, you would have to get the cat to create a path to ground (the load) for any current to flow. So you could have 10,000v running to the body and the cat will just still sit there on your car and purr away.

But don't then try to shoo it off unless YOU have dry, rubber boots on!
