I just wanted to say that these specially designed mats that go under your door and around your doorway are genius. They have completely stopped my cats from ripping up the carpet when they want in or out of a room. I have them for all of the bedrooms and bathrooms to protect the carpet. My only worry was that they might be too thick and either not fit or make me trip over them but neither of those things have happened. They have saved my carpet my carpet from further damage and I have no reserves about getting new carpet. Because I would have rather had destroyed carpet than declaw any of my cats babies.
