Go ahead and laugh. I've got cats that keep jumping on the car and I'm tired of taking the cover off and on every time I take the car out. The thought behind it is to deter them from jumping up. V1 just the tubing was a fail. V2 slowed them down but then they were jumping over the back. V3 with the cardboard overhang has been cat free for three days now.
