Why do cats groom each other? Weird cat behavior explained

Grooming is a common behavior for cats, and chances are, your cat takes several baths a day to keep himself clean. Cats are naturally fastidious, and that instinct serves their health and safety well. While many cats are thorough self-groomers, some cats enjoy having a little help every now and again and might groom fellow felines. If you notice your cats grooming each other, don’t worry. This behavior is normal and even indicates that your cats are trusting and bonded with each other. If your cat engages in mutual grooming with another cat, you’re seeing a natural behavior and a happy, secure cat.

Understanding self-grooming

To understand why cats groom each other, you need to first understand why cats groom themselves. Grooming has multiple important purposes, and they all contribute to your cat’s health and safety.

When your cat grooms himself, he’s removing dirt from his hair and may also remove parasites. He’s keeping his coat in good condition, helping to prevent mats from developing, which can lead to skin irritations. Grooming also helps distribute the natural oils in your cat’s coat, so the coat is healthier and stronger, too.

But grooming also removes scents — particularly the scents of food — from your cat. In the wild, this has the important purpose of preventing predators from smelling and then following the cat. It’s an important safety measure, and your cat’s instinct to groom himself could save his life in the wild.

Understanding mutual grooming

So, why do cats groom each other? This behavior starts at birth, when mother cats groom their kittens to stimulate them to have bowel movements and to breathe. This grooming also can help stimulate a kitten’s circulation, and it contributes to young kittens’ health.

When cats get older, they may start to groom each other for similar health reasons. Sometimes cats might focus on grooming the head and neck, which are spots that are difficult for them to get to on their own. This mutual grooming offers convenience over self-grooming.

In some cases, grooming can also be an important social activity that helps reassure cats. It can be a sign of affection and an important element of bonding. Cats often purr while they’re grooming themselves or others, and this also can be a soothing behavior. It’s unlikely that cats who aren’t highly familiar with each other would engage in mutual grooming, but cats who are good buddies and who trust each other are much more likely to groom each other.

When grooming turns eventful

Sometimes, cats who are grooming each other may suddenly break up the grooming session and seem to turn aggressive. This can happen when one cat is just done with the grooming and needs the other cat to lay off. Most cats who will groom each other are already good companions, so they’re unlikely to truly do any harm to each other and will probably sort out their differences with a small squabble.

It’s also possible that what looks like violence could be your cats engaging in play. Play fighting and wrestling are a natural behavior for cats, especially kittens. After a good grooming session, one cat might initiate a play session, and at first glance it can look a lot like fighting. If you watch for a little longer, though, you’ll probably see that your cats are both having a good, playful time.

Grooming is an important behavior for cats, and monitoring your cat’s grooming habits can give you insight into his overall health. If your cat is grooming others and has a good-looking, healthy coat, then his grooming habits and health are probably just fine. But cats can also take grooming to the extreme, and some cats may groom themselves excessively, leaving bald patches and sparse coats. This over-grooming can be caused by stress, but it can also be the result of allergies or parasite infestations. In contrast, if your cat is grooming himself less and less, you might see that his coat becomes dull, matted, and unhealthy. This lack of grooming can also indicate that your cat isn’t feeling well, and a trip to the vet is in order. You can use your cat’s grooming habits to gauge his health and well-being, especially when you understand what motivates your cat to keep himself — and sometimes others — clean.

Why do cats like being pet? (and where you should pet them)
This is the right way to pet a cat

Every cat owner has gone to pet their fur baby, only to get swatted in the face by their kitty. Sometimes, it can seem like cats don't enjoy affection at all. But while these finicky animals might prefer you pet them only on their terms, most cats do want pats from time to time, in the right places, of course. So why do cats like being pet? We'll walk you through where, how, and why to pet your four-legged feline friend.
Why do cats like being pet?

Like so many things, you need to understand their basic nature to have a better sense of why they yearn for your attention. Even in the wild, you might see cats groom and snuggle together, which has evolved into head scratches and belly rubs. Why else do kitties want you to stroke them? Here are four reasons.
It feels good
You may also spy your cat rolling on the carpet, lying in the sun, or licking their paws. While these actions can have practical reasons, for the most part, our beasties engage in the behaviors because they feel good. Cats can also be satisfied by a petting session from their human, and so they will look for you to fulfill this need.
They like you
It can be tricky to build trust with your pet, but once that's established, your cat will love to act affectionately toward you. You'll find them start to approach you more, perhaps rubbing against your legs or wanting to sit on or near you. Eventually, you'll graduate to outright petting and then they'll be asking for pats all the time.
You should smell like them
Many animals feel that their humans need to smell like them, which is a form of ownership to your mouser. Once you are scented just like your kitty, everyone will know that you're part of their group and belong to them. Cats also rub their bodies, and therefore pheromones, on things in your household, like your bed or your clothes, for the same reasons.
They want attention
We all crave attention sometimes — even our elusive cats. When they want you to notice them, it could be as a result of boredom or anxiety, but they also might just want you to dote on them, as they deserve. You'll soon pick up on your sweet pet's personal preferences and get a good feeling for when they want some love.
