Why Do Cats Lick You?

Cats are known for their fastidious grooming habits, spending hours each day cleaning their fur with their tongues. But why do cats also lick their humans? This question has puzzled many cat owners, as well as those who simply love felines. In this blog post, we will explore the science behind cat licking and the reasons why cats may lick their humans. We'll also look at the different types of licks and when licking behavior may become problematic. By the end, you'll have a better understanding of why your furry friend is showering you with slobbery kisses!

The Science Behind This Behaviour

To understand why cats lick humans, it's important to understand the science behind this behavior. The anatomy of a cat's tongue is quite unique and plays a significant role in their grooming behavior.

Cats have rough, spiky tongues that are covered in tiny barbs called papillae. These papillae are made of keratin, which is the same material that makes up human hair and nails. When a cat licks, these papillae help to pull out dirt, loose fur, and debris from their own fur.

Additionally, a cat's tongue has special glands that secrete saliva. This saliva contains enzymes that help to break down dirt and oils in a cat's fur, as well as bacteria that can cause infections.

When it comes to grooming humans, cats may also be attracted to the taste and smell of our skin. Humans naturally produce oils and sweat that can be appealing to cats, especially if they have a close relationship with their owner.

Overall, the unique anatomy of a cat's tongue, combined with their natural grooming instincts, makes licking an important and instinctual behavior for cats.

Why Cats Lick Their Owners?

As we've already mentioned, cats may lick humans for a variety of reasons. Let's take a closer look at some of the most common reasons why cats may lick their owners:

  1. Affection and Bonding: Cats may lick their owners as a way to show affection and strengthen the bond between them. When a cat licks their owner, it may release endorphins in the cat's brain that create a sense of pleasure and comfort.
  2. Seeking Attention: Cats may also lick their owners as a way to get attention. If a cat wants food or playtime, for example, they may lick their owner's hand or face to get them to pay attention.
  3. Marking Territory: As we mentioned earlier, cats have scent glands in their tongues. When a cat licks their owner, they may be leaving behind their scent as a way to mark their territory and let other cats know that this person is their property.
  4. Stress relief: Licking can be a calming behavior for cats, and they may lick their owners when they are feeling anxious or stressed. If your cat is licking you excessively, it could be a sign that they are feeling overwhelmed and need some extra comfort.
  5. Preparing for mealtime: Cats may also lick their owners as a way to solicit food. When they lick you, they are trying to stimulate your natural grooming behavior, which could lead you to pet or feed them.
  6. Tasting and Smelling: Finally, cats may also lick humans because they are curious about the taste and smell of our skin. Cats have a highly developed sense of smell and taste, and they may be interested in the unique odors and flavors that come from our skin.

Overall, there are many reasons why cats may lick their owners. While it can be a bit uncomfortable at times, it's important to remember that licking is a natural behavior for cats and is usually nothing to be concerned about.

But You Should Know This

While cats licking their owners is a natural behavior, there are some things you should know about your cat's licking habits to ensure that they are healthy and safe. Here are a few important things to keep in mind:

  1. Be Aware of Excessive Licking: While some licking is normal, excessive licking can be a sign of an underlying health issue or stress. If you notice that your cat is licking themselves or you excessively, it's important to consult with your veterinarian to rule out any medical conditions.
  2. Licking Can Be Harmful: While cats' tongues are rough, they can still cause harm to human skin. If your cat's licking becomes too rough or aggressive, it's important to discourage the behavior to prevent any injury.
  3. Some People Are Allergic: Cat saliva can contain allergens that can cause allergic reactions in some people. If you or someone in your household is allergic to cats, it's important to limit contact with the cat's saliva to prevent any reactions.
  4. Licking Can Transfer Bacteria: Cats' mouths can contain bacteria that can be harmful to humans, such as Pasteurella multocida. If your cat has open sores or is otherwise sick, it's important to be cautious when allowing them to lick you to prevent the spread of bacteria.

By being aware of these potential issues, you can ensure that your cat's licking behavior remains a safe and healthy part of your relationship with them.

Types of Cat Licking Behavior

Cats are known for their grooming habits, and licking is a significant part of their behavior. Here are some types of cat licking behavior:

  1. Self-grooming: Cats spend a considerable amount of time grooming themselves. They use their rough tongue to clean their fur, remove dirt, and distribute natural oils. This behavior helps keep their coat clean and shiny.
  2. Social grooming: Cats in social groups often groom each other to reinforce social bonds and show affection. This behavior is also known as allogrooming.
  3. Licking for communication: Cats use licking as a way to communicate with their owners or other cats. For example, a cat may lick its owner's face or hands to show affection or to solicit attention.
  4. Licking as a stress reliever: Some cats may lick excessively when they are stressed or anxious. This behavior is known as psychogenic alopecia and can lead to hair loss and skin irritation.
  5. Licking for medical reasons: In some cases, cats may lick excessively due to medical conditions such as allergies, skin infections, or dental issues.
  6. Licking objects: Some cats may lick objects such as plastic bags, wool, or other materials. This behavior is known as pica and can be a sign of an underlying medical or behavioral problem.
  7. Licking after eating: Cats often lick their mouths and faces after eating to clean themselves and remove any food particles from their fur.

How to Respond to Cat Licking

Sure, here's an example of what you could include in the section on how to respond to cat licking:

  1. Positive reinforcement: If your cat is licking you in a way that you find enjoyable, you can respond by praising them or giving them a treat. This positive reinforcement can help encourage the behavior and strengthen your bond with your cat.
  2. Redirect the behavior: If your cat is licking you too much or too aggressively, you can redirect their behavior by offering them a toy or a treat instead. This can help distract them and give them an alternative outlet for their energy.
  3. Provide enrichment and stimulation: Cats that are bored or stressed may engage in excessive licking as a way to relieve their anxiety. Providing your cat with plenty of toys, scratching posts, and interactive playtime can help reduce stress and prevent unwanted behavior.
  4. Set boundaries: If you don't want your cat to lick you, it's important to set clear boundaries and discourage the behavior. You can do this by gently pushing your cat away or saying "no" in a firm tone. It's important to be consistent with your boundaries and not give in to the behavior, as this can reinforce the behavior and make it more difficult to manage in the future.

Remember, every cat is different, and what works for one cat may not work for another. It's important to observe your cat's body language and respond appropriately to their needs. With patience and positive reinforcement, you can help encourage the behaviors you want and discourage the ones you don't.
