Your cat is leaving a chemical on your face. Its name is F4. The translation is “you’re family,” and cats only leave it on people and animals they trust. F4 was identified in 1998 by a French researcher named Patrick Pageat. Pageat found five different chemicals coming out of glands on a cat’s cheeks, chin, and forehead, and labeled them F1 through F5. F2 has to do with mating. F3 is for territory, and cats use it to mark furniture and door frames. (You can buy a synthetic version of F3 at any pet store, sold under the brand name Feliway.) F4 is the social one. The face-rub itself has its own name too. Scientists call it bunting when face hits face, and allorubbing when the whole body gets involved. F4 builds what researchers call a colony scent. In a wild cat colony, the cats rub against each other constantly until they all smell the same. The shared smell works like a family ID. Cats with the colony scent don’t fight each other. Cats without it get treated like intruders. A study of feral cats at Church Farm, run by biologist David Macdonald, found this rubbing made up 15.7% of all social interactions in the colony. Cats are picky about who gets F4. They reserve bunting for individuals they bond with. A stranger walking in won’t get bunted, even if they try to pet the cat. A new cat being introduced to the home won’t get bunted either. Furniture and walls get F3, the territory chemical, not the social one. Bunting comes out only for the social bond. When your cat plows its face into yours, you’ve been chemically classified as family. The behavior comes from kittenhood. Kittens rub their faces on their mom as a greeting and as a way to beg for food. Adult cats keep the move and redirect it at the people and animals they bond with. When a cat rubs its face on yours, it’s doing the same thing it used to do to its mother. In feral colonies, this rubbing flows in one direction, and the direction reveals status. Cats on the edges of the group rub toward cats at the center. Lower-status cats rub toward higher-status ones. Kittens rub toward the adults that raised them. The pattern is consistent enough that researchers use it to read social status in the colony. So when your cat plows its face into yours, the gesture also says “you’re the one with the food and the warm bed.”
