When you see two cats gently licking each other's fur, it's one of the most heartwarming sights in the cat world. But why do cats groom each other? This behavior, called allogrooming, isn't just about cleanliness—it's a complex social behavior that reveals deep truths about cat relationships.
Cats that groom each other typically have a close bond and view each other as friends. Whether it's affection, trust, or the establishment of social structure, this mutual grooming reveals a lot about your cats' relationship.
4 Key Reasons Why Cats Groom Each Other
1. Bonding & Affection: The Primary Reason
Felines are social creatures, and grooming each other is the perfect bonding activity. Cats groom each other to express social bonds and affection, according to Steve Dale, CABC.
- Shows trust and friendship—Mutual grooming (allogrooming) is a clear sign of affection
- Strengthens social networks—Licking helps cats build relationships and establish social connections
- Mother-kitten bonding—Mothers groom kittens to bond before they learn self-grooming
- Creates unified group scent—Licking transfers each cat's scent, marking them as part of the same social group
When cats groom each other, they're not just cleaning; they're sharing scents to create a unified group smell. This group scent fosters community and reduces aggression in multi-cat homes.
2. Hygiene Help: Cleaning Hard-to-Reach Areas
While cats are meticulous at cat self grooming, they may struggle to reach certain areas. Licking each other helps clean hard-to-reach spots like the back of the neck, ensuring both cats stay clean and healthy.
Cats will groom one another to:
- Remove dirt, debris, and parasites from fur
- Reduce infection chances
- Clean areas they can't reach themselves
Although felines can clean themselves completely, a grooming session from another cat provides additional health benefits.

3. Stress Relief: Natural Mood Enhancement
Grooming can be a soothing activity that helps reduce stress and provide comfort. The repetitive movement often feels relaxing for both the groomer and the recipient.
How it works:
- The act releases endorphins—natural mood enhancers
- Helps cats relax and promotes a calm environment
- Provides comfort during tense situations
Even though cats only groom each other if they're friends, it can serve as tension relief after conflicts.
4. Hierarchy & Dominance: Social Structure Indicator
In multi-cat households, grooming can indicate social hierarchy. Researchers found that "higher-ranking" cats are more likely to groom lower-ranking cats, similar to how mothers groom kittens.
However, what looks like "dominance" may simply be cats with different personalities—demanding cats letting laid-back ones have their way.
When Cats Groom You: Special Significance
Your cat may even try to groom you by licking your arms or combing your hair with its paws—clear signs of trust and love. When a cat allows another to groom them, it shows trust.
