I wonder, do you park under a low hanging branch? You might have squirrels or possums using it as a quick path to the ground. Cut off the tree branch and you should be good. Cats can do this as well, but most of them keep claws retracted when jumping on a slippery surface.
I second the idea of installing a camera, and don't advertise that you are doing it. You want to catch the SOB. Wouldn't it be really great if the guy goes to jail?
How can you say that? We don't know size and location, which seems like vital info before convicting the cat.
FWIW, my cat has vicious claws, and likes to sit on the roof of my car, but has not yet seemed to leave scratches. There's little point in him extending his claws into impermeable surfaces, it's not going to help with traction. I have seen him sliding down the windshield...
The OP never gave the info asked and he hasn't responded or posted for two months. Either the "mothe" destroyed the car or him? Man, I've seen those Japanese monster movies and let me tell you the things that a "mothe" can do are hideous!
Yeah, the only thing the cat will do to the outside of your car is leave dusty paw prints if there is light coat of dust on the car--that's the worse case scenario. Or he might leave his paw prints on your door handle. Cats can usually do or accomplish just about anything they want. Cats know things.
No reason to limit it to cats. In my area racoons, fox, dogs all like to treat my vehicle as a super highway. I always assumed they use it to get a good look over my yard for the nights meal. in the snow the tracks give them up. but i live in a house with a big back yard surrounded by even bigger fields.

I use to find diff swirls marks in my black car everytime I would pick it up from the 24hr garage as well, I got so pissed off that after 2 months I started parking again in the streets instead of having those CentralParking workers touch my car.
