Why do cats purr and scratch? - in detail
Cats purr and scratch as part of their natural behaviors, which serve multiple purposes in their daily lives. Purring is a complex vocalization that cats produce by vibrating their vocal cords while inhaling and exhaling. This behavior is often associated with contentment and relaxation, such as when a cat is being petted or resting in a comfortable environment. However, purring can also occur in stressful or painful situations, suggesting it may function as a self-soothing mechanism. Some studies indicate that the frequency of a cat's purr can promote healing and reduce inflammation, which may explain why cats purr when injured or unwell. Additionally, kittens purr to communicate with their mother, signaling their presence and well-being during nursing.
Scratching, on the other hand, is a multifaceted behavior rooted in a cat's instincts. Cats scratch to maintain their claws by removing the outer sheath, keeping them sharp and healthy. It also serves as a form of exercise, stretching their muscles and tendons. Scratching is a territorial marker, as cats leave both visual signs and scent marks from glands in their paws, which communicate their presence to other animals. This behavior helps establish boundaries and reduce conflicts in multi-cat households or outdoor environments. Providing appropriate scratching surfaces, such as scratching posts, can redirect this behavior away from furniture and other undesirable objects. Both purring and scratching are deeply ingrained in a cat's biology and serve essential functions for their physical and emotional well-being.
