This can be a little irritating, especially when it's not your cat. Several years ago my neighbor had a cat that would sleep on the hood of my truck, and it always left paw prints. If my truck was already dirty, it was not that big of a deal, but if I washed my truck,  almost invariably that damned cat would put his prints all over the hood. I always had the feeling he knew what he was doing. One day that cat just disappeared (it wasn't me, honest) and that was that. I think the neighbor still thinks I did something to that cat.

I have three cats so I put up with this one all the time.  However, it depends on which car they leave their prints on as to whether or not I get upset.  The black car, YES! The grey car, no.

I much prefer this to the neighbors dog pooping on my lawn.Next time they might find it returned to their porch in a flaming brown bag!

The trick here is not hitting your vehicle when you shoot.

It always amazes me how much dirt they can drag around on those little paws, but after all, it does wash off. My cat, Angus, is a bad offender in this regard.
