Umm, car covers are a NO. They make it easier for them to scale the car instead of jump on it. And scaling means CLAWS. Claws mean scratches, through the cover eventually, and into the PAINT. Now your out the car cover, the money for said cover, AND the paint. If its this bad, and my solution doesn't work, well, there is only one thing left.
Kill them. All of them.
Heartless, yes. But it works, and it is final. When it comes to my car, I have no problem with it, if they are on my property. Legal too by the way
