I'm currently parking my Roadster in a carport with no door (although I'm thinking about installing one), and recently with the rain we've been having I'm getting a lot of cats coming and sleeping, cleaning themselves, etc. on top of my Roadster! The main thing I'd like to avoid is having them scratch it up, but I guess that is what is going to happen, or is happening. Fortunately I just had a glass-based coating put on the car which I guess would help, but I'm sure it's not as strong as cats' claws.
Does anyone else have this problem, and what is a good way to get rid of them? (get a garage door, chain dogs to roof of the car, etc. would work I guess....)
