Why Do Cats Groom Each Other? Is It Normal?

If you’ve ever watched one cat lovingly lick another’s head like a tiny spa attendant, you might’ve wondered what’s really going on.

Good news: in most cases, it’s totally normal—and actually kind of sweet.

Let’s unpack why cats groom each other, what it means for their relationship, and when it might be time to step in.

Quick Answer: Why do cats groom each other?

Cats groom each other to bond, show affection, share scent, and reinforce social hierarchy. This behavior—called allogrooming—is completely normal and usually a sign of trust and companionship. As long as both cats seem relaxed and there’s no aggression, it’s healthy feline communication.

Who This Is For

This guide is for:

Multi-cat households
New cat parents learning feline behavior

What Is Allogrooming?

“Allogrooming” is the fancy term for mutual grooming between cats.

It usually involves:

Licking faces, ears, and heads
Gentle nibbling around the neck
One cat holding still while the other does the work

This behavior starts in kittenhood, when mom cats groom their babies—and many adult cats carry this bonding ritual into adulthood.

The Most Common Reasons Cats Groom Each Other

Let’s decode the lick-fest.

🐾 Bonding & Affection

This is the big one.

Cats groom each other to strengthen social bonds. Think of it as their version of holding hands.

If both cats look relaxed—soft eyes, calm posture—it’s a positive sign of friendship.

🐾 Sharing Scent (aka “You’re One of Us”)

Cats rely heavily on scent to identify family members.

By grooming each other, they mix scents and create a shared group identity. It’s basically their way of saying, you belong here.

🐾 Social Structure

Sometimes the more dominant cat initiates grooming to reinforce hierarchy.

It doesn’t mean anything negative—it’s just feline politics.

Usually, the lower-ranking cat accepts it peacefully.

🐾 Comfort & Stress Relief

Grooming releases calming hormones.

In busy households or during changes (new pets, moves, visitors), cats may groom each other more as a way to self-soothe.

When Grooming Is Totally Normal

Mutual grooming is healthy when:

Both cats participate willingly
There’s no hissing, swatting, or chasing afterward
Fur isn’t thinning or missing
Sessions look calm and gentle

In these cases, congratulations—you’ve got bonded cats.

When Grooming Might Be a Problem

Occasionally, grooming crosses into over-grooming.

Keep an eye out if you notice:

Bald spots or irritated skin
One cat always grooming while the other resists
Grooming turning into biting or fighting
Excessive licking paired with hiding or anxiety

That could signal stress, medical issues, or relationship tension—and it’s worth checking with your vet.

How to Support Happy, Healthy Cat Relationships

From fitting thousands of pets (yes, cats included), here’s what helps keep peace in multi-cat homes:

✔ Provide Enrichment

Use toys, climbing spaces, and even lick mats (cats love them too!) to reduce boredom and stress.

✔ Give Each Cat Their Own Resources

Separate food bowls, litter boxes, and resting spots help prevent power struggles.

✔ Encourage Safe Exploration

If your cats enjoy supervised outdoor time, a secure cat harness and leash set lets them explore safely while burning off nervous energy.

✔ Reward Calm Behavior

Keep treats handy—using a small treat pouch during introductions or tense moments helps reinforce positive interactions.

And yes, even cats deserve stylish accessories. A subtle collar charm can add personality without disrupting comfort (just make sure collars are breakaway-safe).

FAQs

Is it normal for one cat to groom the other more?

Yes. Often one cat naturally takes the “caretaker” role. It’s only a concern if the other cat seems stressed or tries to escape.

Why does grooming sometimes turn into fighting?

Overstimulation can happen. If licking turns into biting or chasing, it’s time for a quick distraction or separation.

Do cats groom humans for the same reason?

They sure do. If your cat licks you, congratulations—you’ve been officially accepted into their inner circle.
