Why Does My Cat Headbutt Me?

What's happening when they headbutt?

Cats have concentrated scent glands on their forehead, temples, cheeks, and chin. When they press their head against you, they're transferring pheromones that mark you with their scent. This creates a familiar scent profile that tells other cats "this person is part of my group." The behavior is called bunting, and it's one of the strongest affiliative signals in feline body language. Cats are selective about who they bunt; it's reserved for individuals they feel genuinely bonded to.

Is it different from rubbing?

Head bunting is more deliberate and direct than general body rubbing. When a cat rubs their flanks along your legs, it's scent marking and greeting combined. Head bunting involves bringing the face (with all its sensitive sensory organs) into direct contact with you, which is a higher-trust gesture. Some cats bunt with considerable force, nearly knocking glasses off your face or pushing objects off surfaces with their enthusiasm.

Do cats headbutt each other?

Yes, and it serves the same function. Cats that share a close social bond will headbutt each other as a greeting, a bonding ritual, and a way to maintain a shared group scent. Colony cats use mutual bunting to reinforce social bonds within the group. When your cat headbutts you and then headbutts another cat in the household, they're weaving everyone into the same scent network.
