Product Description: Created by a passionate pet lover who refused to declaw her cats, the patented CarPET Scratch Stopper stops cats from scratching carpets at doorways INSTANTLY without harm to cats or carpets. 100% hassle-free installation and easy to use, this product requires no cutting, modification, hooks or grippers of any kind. Simply place inside your doorway and your carpet is immediately protected. The CarPET Scratch Stopper is the first device ever created that effectively solves a problem of epidemic proportions; cats scratching carpet at closed doors. How It Works: Simply place the CarPET Scratch Stopper inside the doorway. When a cat tries to scratch at the carpet by a closed door, its claws will no longer be able to grip onto the carpet and will slide right off the device. Cats immediately lose interest and the destructive behavior is instantly eliminated.About the product: The unique design contours the outline of your door frame and protects the areas most prone to scratching when doors are closed. The CarPET Scratch Stopper is made with heavy-duty, semi-flexible plastic that allows normal foot traffic, yet it is thin enough to close doors over. The bottom surface is equipped with grippers to prevent movement, and the top has a protective anti-slip surface. The CarPET Scratch Stopper can be used on an on-going or as-needed basis; it is simply a matter of individual preference.
