why does my cat sleep by my head

Cats sleep by their owner's head primarily because they seek warmth, feel safe, and want to be close to their owner. The head is one of the warmest parts of the body due to body heat, and cats naturally enjoy cozy, warm places. Additionally, sleeping by the head allows the cat to be near its owner's comforting scent and feel secure, reflecting trust and affection. This behavior can also be a sign that the cat views the owner as part of its social group, since cats tend to cuddle close to those they consider family for comfort and protection. Some cats may also sleep by the head to maintain territorial marking through scent or because it helps them feel safe from disturbances during sleep. Overall, it's a mix of seeking warmth, showing affection, trust, and a desire for security.
