Why Does My Cat Steal My Kisses? The Surprising Reason Behind This Quirky Feline Behavior

Why Does Your Cat “Kiss” You Back?

If your cat ever licks your face after you give them a kiss, you may be left wondering why they engage in this peculiar “kissing” behavior. When your loving kitty reaches their tongue out to lick your lips or nose after a smooch, it can seem like they are returning the affection or trying to “kiss” you back. However, there’s more to this common cat behavior than meets the eye. Your cat licking your kisses away likely has more to do with their natural grooming instincts and scent investigation than showing affection. Let’s explore some of the fascinating reasons behind this behavior!

Explaining the Behavior

Cats lick human faces for several reasons, most of which are completely natural cat behaviors. One key reason is that cats have scent glands around their mouth and nose. When a cat licks a human face, the cat transfers its scents via saliva to the person. According to cats.com, “Cats have scent glands around their nose and mouth, so when they lick you, their scent will transfer to you. This is known as allogrooming and is a sign of bonding.”

By spreading their scents to their human companions, cats are essentially gathering and sharing information. The scents provide cats with detailed information about the humans, enabling cats to recognize their owners. Licking is a tool cats use to become familiar with things and other animals in their environment.

Scientific Explanation

One scientific explanation for why cats lick their owner’s kisses off involves the cat’s Jacobson’s organ. Cats have a special organ called the Jacobson’s organ located in the roof of their mouth. This organ contains sensory cells that detect pheromones – chemical substances that carry information between members of the same species (Cat Behavior Associates, 2012).

When cats lick their owners, they pass pheromones from the owner’s skin and saliva onto the Jacobson’s organ. This helps your cat gather information about you through the pheromones you produce. Licking deposits the pheromones directly onto the sensory neurons inside the cat’s Jacobson’s organ. So when your cat licks your kisses off, it is collecting the pheromones from your saliva and essentially “tasting” you.

Social Bonding

One primary reason that cats lick their owner’s faces is as a sign of social bonding and affection. Similar to how cats groom each other, face licking is a way for cats to show kinship and friendship with their owners. When a cat licks another cat, it is a sign of companionship and care between those cats 1. Your cat licks your face for the same reasons – to show you friendship, create closeness, and display their fondness of you. Face licking is a social bonding behavior that allows cats to strengthen connections within their family groups, which includes you.

Scent Mixing

Cats have scent glands around their mouth, cheeks, tail, and paws. When a cat licks a human, the cat transfers some of its scent onto the human. By mixing scents like this, the cat is able to blend its own scent with the human’s scent.

According to Catster, when a cat licks a human, they are “marking you as someone who belongs to them” (https://www.catster.com/guides/do-cats-lick-themselves-to-get-your-scent-off/). Cats have a strong sense of smell, and blending scents reinforces the social bond between cat and human. It signals that the human is part of the cat’s family or social group.

So when a cat licks your kisses off, it is simply mixing your scent with its own scent. This is a natural cat behavior and a sign that the cat feels a close social connection with you.

Owner Tastes Interesting

One scientific explanation for why cats lick their owner’s kisses off relates to taste preferences. Research shows that cats have significantly fewer taste buds compared to humans – only having a few hundred versus human’s 9,000+ taste buds. This means cats experience taste differently than humans.

In particular, cats lack receptors for detecting sweet tastes [1]. They can only identify the basic tastes of bitter, sour, salty, and umami. Interestingly, human skin has a slightly salty taste from sweat and oils that cats likely find appealing [2]. Therefore, when a cat licks a kiss off their owner’s face, they may simply enjoy the salty flavor.

Kiss Removal

One reason cats lick their owners’ faces after receiving a kiss is to remove any unwanted smells or tastes left behind. Cats have a strong sense of smell, and some may not appreciate the scent of lipstick, makeup, or food smells from their owner’s mouth and lips. By licking the skin around the mouth, the cat is essentially bathing the area and wiping away any lingering odors or flavors they find unpleasant or strange.

A cat’s nose is like a fingerprint – each cat’s scent is unique. When a cat licks a fellow feline, it is partially mixing its scent with the other cat’s. This exchange helps provide familiarity and mark group identity. When your cat licks you after a kiss, it may be trying to mix its scent signature with yours in an affectionate gesture of acceptance. So in a way, the cat is reciprocating the social bonding initiated by the kiss with a mixing of scents.


One reason your cat licks your kisses off is to bathe you. Grooming and bathing behaviors in cats originate from when they are kittens. Mother cats will lick their kittens as a way to clean them, stimulate circulation, and encourage bowel movements. This licking behavior is instinctual and calming for cats. As adults, cats continue to exhibit grooming behaviors on each other, humans, and even inanimate objects as a way to deal with stress, show affection, and ‘bathe’ their loved ones. When your cat licks your kisses off, it is a sign they are trying to clean and care for you as they would their own kitten. The licking is their natural way to show affection, bonding, and caretaking. So while you may find it unappealing, your cat is actually trying to bathe you as a sign of their maternal love.


In conclusion, there are several reasons why cats may lick their owner’s faces after kisses. The primary explanations include social bonding, scent mixing, and simply finding the taste of their human’s skin or food residues interesting. Face licking demonstrates a cat’s affection and acceptance of their owner into their social group. It also allows them to mingle their scents, reinforcing their bond. Sometimes, a cat may just enjoy the salty taste of their owner’s skin. While licking can seem like an annoyance to humans, it’s important to understand this behavior comes from a loving instinct in cats.

By licking faces, cats are engaging in social grooming and forging intimate connections with their favorite people. While cats may not show affection in exactly the same ways as humans, face licking represents a cat’s version of kisses. So next time your cat tries to lick you after a kiss, remember it’s their unique way of reciprocating affection!
