Scratching isn’t just about claw health, cats also scratch as a way to stretch and flex their bodies. So when you’re choosing a stand-up scratching post, you must find one that’s tall enough to allow your cat to stretch out their whole body. A small post can deny them the exercise and the vital health benefits of scratching and will lose interest very quickly. A post taller/longer than your cat’s length is ideal; they will be able to climb as they scratch, making sure they get a full workout.
