I'm at my wit's end and don't know what to do. One of my two cats won't stop scratching the carpet in my apartment. They have both vertical and horizontal posts, and both cats use them, but this one also will not stop with the carpet. It's not one place, it's like he sprints somewhere, stops, and scratches 5 or 10 times, then runs away. If I cover one area, he just does it 6" away. So, it's not a particular smell on a particular spot unless my whole apartment has that smell; it's not lack of an appropriate place to scratch. Everything I've found on line talks about giving them a scratching post, which I've done. He just doesn't seem to have any incentive to limit his scratching to one place, he really likes digging in the carpet, and I'm tired of picking up pieces he's pulled out knowing I am going to get absolutely screwed by my landlord when I move out.
