Scratching is a common behavior observed in many animals, particularly cats. It involves using their claws to mark territory, stretch their muscles, and maintain their claws' health. This action helps remove the outer sheath of the claw, keeping it sharp and functional. In addition to physical benefits, scratching serves a social purpose. It leaves scent marks from glands in the paws, signaling to other animals that the area is claimed. Providing appropriate scratching surfaces, like scratching posts, can help prevent damage to furniture and satisfy the animal's natural instincts.
