why cats lick each other

Cats lick each other for several reasons, including social bonding, grooming, and establishing hierarchy. This behavior, known as allogrooming, is common among cats that share a close relationship. It helps maintain cleanliness, strengthen social ties, and communicate trust.

The Role of Social Bonding in Cat Licking
When cats lick each other, it often signifies a strong social bond. This behavior is most common among cats that live together or have grown up together. By grooming one another, they reinforce their relationship and show affection. It’s similar to how humans hug or hold hands to express closeness.

Grooming as a Hygiene Practice
Cats are naturally clean animals, and mutual grooming helps them reach areas they can’t clean themselves, like the head and neck. Licking removes dirt, loose fur, and parasites, contributing to overall health. This cooperative grooming ensures that both cats stay well-groomed and comfortable.

Establishing Hierarchy Through Licking
In multi-cat households, dominant cats may lick subordinate ones to assert their position. The cat receiving the grooming often accepts this as a sign of respect. This behavior helps maintain peace and order within the group, reducing potential conflicts over resources or territory.

Stress Relief and Comfort
Licking can also be a calming activity for cats. The rhythmic motion of grooming releases endorphins, which help reduce stress and anxiety. Cats may lick each other more frequently in stressful situations, such as after a move or the introduction of a new pet, to provide reassurance.

Cats lick each other for a variety of reasons, including bonding, hygiene, hierarchy, and stress relief. This behavior is a natural and important part of their social interactions. Understanding why cats groom each other can help owners better interpret their pets' relationships and ensure a harmonious living environment.
