SmartyKat Super Scratcher uses our patent pending process to infuse highly concentrated catnip between each layer of cardboard so the potent catnip scent is released every time your cat scratches. Can be used flat or angled. Catnip naturally stimulates most cats providing a burst of playful energy usually followed by a mellow period. The instinct to scratch is hard-wired into cats. Cats scratch to mark territory and promote healthy nail growth tone muscles and even helps alleviate stress. Discovering your cat s scratching preferences can feel like guesswork. We recommend trying corrugate first because the texture more closely mimics tree bark one of the most common surfaces felines love digging their claws into in nature.SmartyKat gives pet parents the best of all worlds: SmartyKat products are designed to meet child safety standards and are backed by our 100% satisfaction.
