Cats are known for their unique and sometimes peculiar behaviors, and one of the more unusual habits that some cats exhibit is licking their owners’ eyelashes. While this behavior may seem harmless or even endearing, it can leave many cat owners wondering why their furry friend is doing this in the first place.

Understanding the potential reasons behind this behavior can provide valuable insight into a cat’s instincts, social behaviors, and even nutritional needs. As such, it’s important for cat owners to explore this topic further to better understand why their feline friend may be licking their eyelashes.

Natural Instincts

Cats are natural groomers, and they use grooming as a way to keep themselves clean and free of parasites, as well as to maintain their fur’s condition. However, grooming is not just a physical necessity for cats; it’s also an important social behavior that can help to build and strengthen their bonds with humans and other animals.

When cats groom their owners, they are essentially treating them as part of their social group, showing affection and trust. This behavior is similar to how cats groom each other in the wild, and it’s a way for them to establish a sense of closeness and security with their humans. In contrast, other animals and humans may not exhibit this kind of grooming behavior, making it a unique aspect of cat behavior.

Scent Marking

Another reason why cats may lick their owner’s eyelashes is to mark them with their scent. Scent marking is a behavior that cats use to communicate with other cats and establish their territory. When cats rub their face against an object or a person, they are leaving behind a chemical message that tells other cats that this is their territory.

Cats have scent glands on different parts of their face, including their chin, cheeks, and forehead, which they use to mark things they consider to be their own. The area around the eyes is also a common spot for cats to mark, which could explain why some cats may lick their owner’s eyelashes.

By marking their owners in this way, cats may be trying to establish their bond and territory, as well as leaving their scent on a familiar and trusted human. While scent marking is a common behavior in many animals, cats have a unique way of using it to establish their social and territorial position.

Nutrient Seeking

Another reason why cats may lick their owner’s eyelashes is that they may be seeking out certain nutrients that can be found in tears or other bodily fluids. Tears contain a variety of compounds, including electrolytes, proteins, and enzymes, that may be appealing to cats.

Some cats may also be attracted to the salt content of tears, which can be a rare treat for them since their diet usually lacks sodium. Additionally, some cats may be drawn to the scent of their owner’s face or breath, which can signal to them the presence of other desirable compounds.

While nutrient-seeking behaviors are common in many animals, cats have a unique ability to detect and respond to specific scents and flavors. However, it’s important to note that excessive licking can lead to irritation or infection, so owners should monitor their cat’s behavior and consult with a veterinarian if they have concerns.

Cats are known for their curious behavior, and one of the peculiar habits that many cat owners may have observed is their cat licking their eyelashes. While it may seem strange, there are several reasons why a cat may engage in this behavior.

One possible explanation is that cats may be seeking out certain nutrients that can be found in tears or other bodily fluids. This behavior is not uncommon in the animal kingdom, as other animals, such as butterflies and bees, also seek out nutrients in bodily fluids. However, it is important to note that this theory is still being studied, and there is no conclusive evidence to support it.

Stress and Anxiety

Stress and anxiety can also be a potential reason for cats to exhibit grooming behaviors like licking their owners’ eyelashes. Cats may find comfort in grooming activities and use it as a way to soothe themselves when feeling anxious or stressed.

Some potential triggers for stress or anxiety in cats include changes in routine, introduction of new pets or people, or loud noises. Stress-relieving behaviors in cats can also include kneading or purring.

Similarly, other animals like dogs and primates have been observed to engage in grooming behaviors as a way to cope with stress or anxiety. Overall, understanding the potential reasons for a cat’s grooming behavior can help pet owners better care for and bond with their feline companions.


In conclusion, there are several potential reasons why a cat may lick their owner’s eyelashes, including natural grooming behaviors, scent marking, nutrient-seeking, and stress relief. While this behavior is generally harmless and may even be seen as a sign of affection, it is important for cat owners to be aware of their cat’s body language and behavior to ensure their well-being.

If a cat’s grooming behaviors become excessive or concerning, it is recommended to seek advice from a veterinarian or animal behaviorist. Overall, understanding the reasons behind a cat’s behavior can strengthen the bond between cat and owner and lead to a happier, healthier relationship.
