Mines not (note avatar). Brings them home to play with! I have the same issue but with my own cats. They love to lay on the cars but usually the wife's. Mine is covered. I have caught them on it and when that occurs I remote start it or hit the alarm. They will jump off. Just a warning though, if you startle them too much they will accelerate their departure and use the claws! Cats are won't stay in (on) one place for too long. They get bored with it and will move on. If you stay on top of scaring them they will learn not to get on the car. FYI.
