why do cats rub their face on things

Cats rub their faces on things primarily to leave scent marks using the multiple scent glands on their cheeks, chin, and around their mouth. This behavior, called "bunting" or head rubbing, serves several purposes: marking territory and belongings, signaling comfort and happiness, showing affection, and even gathering information about their environment. The scent they leave is a way for cats to communicate with other cats, marking objects or people as part of their domain. When cats rub their faces on humans, it is often a sign of affection and trust as well as marking the person with their scent to claim them as "theirs." Additionally, this action can provide comfort to cats by spreading familiar scent pheromones that help them feel secure. Male cats tend to bunt more frequently, especially during mating season to signal their presence.
