The SmartyKat Super Scratcher Chaise utilizes our patent-pending process to infuse highly concentrated catnip between each layer of cardboard, so a strong catnip scent is released every time your cat scratches. In addition, the Super Scratching Chair provides an ideal perch for your cat. Cats scratch to mark territory, promote healthy nail growth, exercise their muscles, and even help relieve stress. Discovering your cat's scratching preferences can feel like a guessing game. We recommend trying corrugated first, as its texture is closer to bark, one of felines' favorite surfaces to paw at in nature.
