Why does my cat sleep on me? Many cats like to sleep on their humans; it makes them feel safe, warm, and comfortable. Cats like to be warm and prefer a slightly higher room temperature than humans. We give off heat, and that appeals to kitty. We are also surprisingly comfortable, and cats associate our smells with care and safety. Many cats also seem lulled by the rhythm of the human heartbeat. Most cats like being close to their person, and it is a compliment. Your cat might also seek out your spot on the bed or your favorite chair when you’re not in the room. It smells like you, they associate it with you, and that’s comforting to them.
