Cat nuzzling is a common yet sometimes misunderstood form of cat communication. Often, your cat will nuzzle against your face or neck, maybe while you're snuggling or when you're trying to get some work done. But, why do cats nuzzle? Is it a diversion technique, or is your cat communicating something more?
How and Why Do Cats Nuzzle?
Rub. Nudge. Prod. Cat nuzzling goes by many names, but it refers to the act of rubbing their head against your chin, cheek or neck. You may even be the recipient of a headbutt, known as "bunting," which is quite literally when your cat knocks their forehead against yours. Think of it as the equivalent of a cat fist-bump!
Like other strange cat behaviors that may puzzle pet parents, rubbing their head against you has a purpose. Cats nuzzle to show affection and to mark territory, behaviors that share the common goal of leaving their scent behind.
Affection
Cats have many scent glands on their head, especially in the nose, mouth and chin area; with each rub against you, these glands leave behind a "mark." Rubbing their head all over you is their way of saying, "I love you." In exchange for nuzzling, your cat probably gets a lot of cuddles from you, which is a strong motivator for repeat behavior.

Nuzzling also is how they learn more about you. As Tufts' Animal Behavior Clinic veterinary behaviorist Stephanie Borns-Weil tells the Cummings School of Veterinary Medicine at Tufts University, your cat may rub on you to show affection, but they also want to "gather information about you." Cats have a very strong sense of smell — much better than their humans' sense — and they use scent as one of their main ways of collecting data about their environment. During nuzzling, your scent transfers to your cat and helps them recognize you, especially when you're first getting to know each other.
