My cat loves to bite and pull at the carpet everywhere there is a seam (between rooms, patches, etc). I've tried squirting him with water, but now he just runs away if I even move while he's doing it. Since I can't be there all the time, I need some way to keep him from ripping up the carpet while I'm at work or asleep. I've seen products that are supposed to keep cats away from an area, but that would require spaying the doorway. I don't want to prevent him from entering those rooms, just to stop messing with the carpet.
