Yes, for the most part, it is perfectly OK for cats to lick humans. It is generally considered a normal behavior and often a sign of affection from your feline friend.
Why Do Cats Lick Humans?
Cat licking, often referred to as "grooming" or "love bites," is a multifaceted behavior deeply rooted in their instincts. Understanding the reasons behind it can help you appreciate this unique interaction.
A Sign of Affection and Bonding
One of the primary reasons cats lick humans is to show affection. When a cat licks you, they are often treating you as a member of their social group or family. This is how mother cats groom their kittens and how cats in a colony show care for each other. It's a way for them to say, "You're one of us."
Grooming Behavior (Allogrooming)
Cats are meticulous groomers. When they extend this behavior to you, it's called allogrooming. By licking you, your cat might be attempting to "clean" you, similar to how they would groom another cat in their pride. This reinforces social bonds and can be a comforting gesture.
Scent Marking
Cats have scent glands around their mouths and on their tongues. Licking you can be a way for them to transfer their scent onto you, essentially marking you as part of their territory or family. This shared scent creates a communal bond and indicates ownership or belonging.
Seeking Attention or Comfort
Sometimes, a cat might lick you to get your attention, especially if they are feeling anxious, bored, or simply want to interact. It can also be a self-soothing behavior that they extend to you during moments of stress or discomfort.
Is Cat Licking Always Safe?
While cat licking is generally harmless, there are a few considerations to keep in mind regarding hygiene and potential health concerns.
Hygiene and Bacteria
A cat's mouth contains bacteria, including Pasteurella multocida, which can cause infections if transmitted to an open wound. While casual licks on intact skin are typically safe, it's always wise to avoid having your cat lick any open cuts, scrapes, or broken skin.
- Avoid: Allowing your cat to lick open wounds or areas of broken skin.
- Wash: Always wash your hands with soap and water after extended play or contact, especially if you have sensitive skin or a compromised immune system.
Rough Tongue Texture
A cat's tongue is covered in tiny, backward-facing barbs called papillae, which give it a sandpaper-like texture. These are excellent for grooming and stripping meat from bones but can feel rough or even a bit painful on human skin, especially sensitive areas. If the licking becomes too rough or uncomfortable, it's okay to gently redirect your cat.
When to Be Cautious
While rare, certain situations warrant extra caution:
- Immunocompromised Individuals: People with weakened immune systems (e.g., due to illness, medication, or age) should be more careful about exposure to animal saliva to minimize any risk of infection.
- Excessive Licking: If the licking becomes obsessive, compulsive, or accompanied by other behavioral changes, it could indicate an underlying issue.
When is Licking Considered Excessive?
As highlighted, cat licking is normal behavior. However, if the licking becomes excessive, compulsive, causes skin irritation, or is coupled with other concerning behaviors like increased anxiety or aggression, it's advisable to talk to your vet. Excessive licking might signal:
- Stress or Anxiety: A change in environment, routine, or the introduction of new pets can make a cat anxious.
- Medical Issues: Rarely, skin conditions, pain, or neurological issues could manifest as excessive licking.
- Obsessive-Compulsive Behavior: In some cases, it can develop into a compulsive disorder.
Your vet can help rule out any medical causes and offer guidance on behavioral modification if needed.
How to Manage or Discourage Licking (If You Don't Like It)
If you find your cat's licking uncomfortable or simply prefer them not to lick you, there are gentle ways to discourage the behavior:
- Redirection: When your cat starts licking, gently move them away or offer an alternative, such as a favorite toy or a petting session.
- Positive Reinforcement: Reward them with praise or a treat when they engage in desired behaviors, rather than licking.
- Distraction: Engage them in playtime with a wand toy or laser pointer to divert their attention.
- Avoid Negative Reinforcement: Never punish your cat for licking, as this can damage your bond and lead to fear or aggression.
