why does my cat sleep on me

Cats sleep on their owners primarily because they seek warmth, feel secure, want to bond, and mark their territory. They like body heat to maintain their higher body temperature and find the owner's presence reassuring and safe, replicating the comfort they felt snuggling with their mother and littermates as kittens. Additionally, by sleeping on a person, cats leave their scent, marking the owner and their surroundings as part of their territory. This behavior reflects a deep trust and emotional connection between a cat and its human. Sleeping on an owner is a sign that the cat feels safe, loved, and bonded.
