Do Cats Really Love You When They Lick You?

Cats Show Affection By Grooming

One of the main reasons cats lick their owners is as a sign of affection and bonding. For cats, licking is a grooming behavior that releases endorphins and helps strengthen social connections. When a cat licks you, it is showing care and familial attachment in the same way it would groom another cat that it has a close relationship with.

Grooming behaviors like licking allow cats to bond with their owners through the release of natural endorphins. The action of licking is calming and soothing for cats, so they often use it to show care and affection for their human companions the same way they would with feline friends or family members. By licking an owner, a cat is essentially saying “I feel safe and happy with you.”

Cats that live together will often groom each other to reinforce social bonds. When your cat licks you, it is extending this same type of affiliative behavior and affection to you as a member of its social group. So licking is your cat’s way of saying you are part of its family!

Cats Have Different Types of Licks

Cats use licks for grooming themselves and others. They have rough tongues with small barbs designed to help detangle and remove dirt from their fur. Licking also releases soothing pheromones that provide comfort and familiarity for cats.

When cats lick people, the type of lick can give clues into their motivations. Long, slow licks are usually a sign of affection. These social licks help strengthen the bond between a cat and their loved ones. As the ASPCA notes, “This type of licking is like a kiss for cats.”

In contrast, short, quick licks are more practical – they are simply grooming you. Your cat is treating you like a fellow feline and sees you as part of their social group. These efficient licks help remove dead skin cells and distribute the cat’s scent. So while not as affectionate, these licks still show your cat cares.

Licking Releases Pheromones

Cat saliva contains pheromones, which are chemical signals that play an important role in feline communication and social behavior. When cats groom each other or lick human companions, they deposit these pheromones. Pheromones convey information about identity, social status, territorial marking, and more.

For cats, pheromones act like fingerprints that allow them to recognize members of their social group. Licking familiar humans, cats, and other animals enables cats to pick up each other’s unique scent and identify friends from strangers or intruders. Cats also use pheromones to mark territory – by spreading their scent through licking, they communicate ownership and security within their environment.

So when a cat licks you, they are essentially mixing their scents and identifying you as a member of their social circle. It’s a way for cats to show acceptance and promote familiarity through chemical signals. The licking behavior strengthens your bond and indicates that the cat feels comfortable and connected with you.

Cats Mark Their Territory By Licking

Cats have scent glands located all over their bodies, including their faces, tails, paws and flanks. When a cat licks an object, person or another cat, they are depositing their scent. According to the Broomfield Veterinarian, “When cats lick and groom other cats, objects, or even their owners, they are mingling scents by leaving traces of saliva behind. This is also referred to as scent marking or territorial marking” [1]. By licking their owners, cats are mingling their scent to show ownership and mark their territory.

A cat’s saliva contains pheromones that communicate information about them. According to Chewy, “Through licking, cats transfer their scents onto objects, animals and people. This deposits pheromones from glands around their mouth onto the licked object to claim ownership.”[2] So when a cat licks their owner, they are mingling scents and claiming them as part of their territory.

Licking May Indicate Medical Issues

Excessive licking can signal medical or behavioral issues in cats. Causes for increased licking include allergies, anxiety, and pain. Allergies to food, fleas, or environmental irritants can cause itchy skin that leads to excessive grooming [1]. Stress and anxiety can also trigger obsessive licking, as the behavior releases soothing endorphins [2]. Underlying pain from conditions like arthritis may cause a cat to lick certain areas repeatedly.

If a cat’s licking becomes excessive or focused on one spot, it’s important to check with a veterinarian. They can examine the cat and determine if the behavior is due to a medical issue requiring treatment.

Some People Are Allergic to Cat Saliva

Cat saliva contains several allergenic proteins that can cause reactions in sensitive individuals. The major cat allergen, Fel d 1, is found primarily in cat saliva. When a cat grooms and licks themself or others, this allergen gets transferred to their fur and dander where it can become airborne or rub off on surfaces.

Common symptoms of an allergy to cat saliva include itching, redness, and swelling where the cat has licked on the skin. Some people may also experience wheezing, runny nose, watery eyes, and other upper respiratory symptoms after being licked by a cat. The reactions can range from mild to severe.

If you experience any type of reaction after your cat licks you, it’s a good idea to get tested for cat allergies. A simple skin prick test performed by an allergist can confirm whether you’re allergic to cats. Once diagnosed, there are ways to manage cat allergies through medications, air filters, frequent bathing of your cat, and other methods to limit exposure to allergens.

Licking Can Spread Parasites

Cats can carry parasitic infections like toxoplasmosis in their saliva. When a cat grooms itself, the parasites can spread from its body into its mouth. If a cat then licks a person, the parasites can potentially be transmitted. According to the CDC, toxoplasmosis infects nearly 23% of the U.S. population (1).

While toxoplasmosis rarely causes symptoms in healthy individuals, it can be dangerous for pregnant women and immunocompromised people. Ingesting infected cat feces is the primary route of toxoplasmosis transmission to humans. However, contact with cat saliva may also pose a risk (2).

Toxoplasmosis can be fatal for fetuses if a mother is infected during pregnancy. It can also cause severe illness in those with weakened immune systems. People with HIV/AIDS, cancer patients taking chemotherapy, and organ transplant patients taking immunosuppressant drugs are at highest risk. These individuals should take precautions to avoid contact with cat saliva (3).

For most cat owners, the benefits of cat licks likely outweigh the small risks. But immunocompromised individuals should be cautious and limit close contact that may involve exposure to cat saliva. Simple precautions like washing hands after interacting with cats can also help reduce risks.




Licking Is Usually a Positive Sign

Licking is typically how cats show affection and support social bonding. When a cat licks you, it’s often a sign that they are happy, feel comfortable around you, and consider you a friend. Licking stimulates the release of endorphins in cats which makes them feel pleasure and joy. It’s one of the ways cats strengthen their relationships and show care for those they are close to, similar to social grooming.

If your cat licks you frequently, enjoy those licks as a positive sign that your cat is bonded to you and sees you as a special companion. The licking shows your cat feels safe, secure, and content in your presence. It’s a natural cat behavior and compliment that the cat chooses to lick you as a way to show fondness and affection. Each lick says “I like you” in the unique way cats communicate.

So next time your cat licks you, take it as a happy kitty kiss. Your cat licking you means they trust you and consider you family. It’s one of the highest forms of cat praise.

Some Licking Is Normal

Casual licking during petting is common. Cats frequently lick themselves and others as part of normal grooming behavior. As social creatures, cats use licking to bond with their owners and show affection. According to PetMD, “When your cat licks you, they are essentially kissing you.”

Cats spend much of their awake time self-grooming and licking their fur. Frequent licking distributes natural oils around their coat and allows cats to inspect for parasites or skin irritations. A few licks given during petting falls within the range of normal cat behavior.

Unless excessive, owners should not discourage the occasional lick from their cat. As PetMD explains, “Cats don’t lick to annoy you, they lick because it makes them happy and reinforces your bond.” Mild licking demonstrates a cat’s satisfaction and contentment with its owner.

Consider a Cat’s Personal Habits

Licking frequency varies between cats. Some cats are naturally more affectionate and groom others more often as a way to bond. Consider your cat’s usual behavior and what is normal for them. A cat that suddenly begins licking their owner much more frequently may indicate an underlying issue causing stress or anxiety.

Frequent lickers simply lick more often as a part of their regular routine and to display affection. It’s common for these cats to lick their owners daily. As long as your cat seems happy and healthy otherwise, frequent licking alone isn’t a concern.

Look for other signs of stress or illness if your cat’s licking habits change suddenly. But in general, frequent licking from a cat that maintains their usual personality and energy levels is a sign they feel relaxed and content around you.
