For a limited time, purchase a Wave door-hanging cardboard cat scratcher from Moderncat Studio and receive a cardboard refill for free! Ships via USPS Priority Mail to US addresses, so you can still get it in time for Christmas.
Wave is a sleek door-hanging cardboard scratcher that looks more like modern art than a cat product. In addition to being stylish, Wave is also eco-friendly and cat-friendly. Unlike most cardboard scratchers that are constructed with glue, Wave is held together with compression, eliminating the need for any adhesive. This also allows you to easily replace the cardboard when it becomes worn. Simply remove the used cardboard pieces from the reusable aluminum frame and replace with a new cardboard refill. The anodized aluminum frame hangs from all styles of doorknobs and has a silicone doorknob protector.
Available from the Moderncat Studio Etsy shop for $45.
