Cats might have a status for independence, however rising analysis suggests we share a singular reference to them — fueled by mind chemistry.
The principle chemical concerned is oxytocin, typically known as the love hormone. It is the identical neurochemical that surges when a mom cradles her child or when mates hug, fostering belief and affection. And now research are exhibiting oxytocin is necessary for cat-human bonding too.
Oxytocin additionally has calming results in people and animals, because it suppresses the stress hormone cortisol and prompts the parasympathetic nervous system (the remaining and digest system) to assist the physique loosen up.
Scientists have lengthy identified that pleasant interactions set off oxytocin launch in each canines and their homeowners, making a mutual suggestions loop of bonding. Till lately, although, not a lot was identified about its impact in cats.
Cats are extra refined in exhibiting affection. But their homeowners typically report the identical heat emotions of companionship and stress aid that canine homeowners do — and research are more and more backing these experiences up. Researchers in Japan, for instance, reported in 2021 that temporary petting periods with their cats boosted oxytocin ranges in many homeowners.
In that research, girls interacted with their cats for a couple of minutes whereas scientists measured the homeowners’ hormone ranges. The outcomes steered that pleasant contact (stroking the cat, speaking in a delicate tone) was linked to elevated oxytocin within the people’ saliva, in contrast with a quiet resting interval with out their cat.
Many individuals discover petting a purring cat is soothing, and analysis signifies it isn’t simply due to the delicate fur. The act of petting and even the sound of purring can set off oxytocin launch in our brains. One 2002 research discovered this oxytocin rush from mild cat contact helps decrease cortisol (our stress hormone), which in flip can scale back blood stress and even ache.
When is oxytocin launched between cats and people?
Analysis is pinpointing particular moments that trigger the discharge of this hormone in our cross-species friendship. Light bodily contact appears to be a first-rate set off for cats.
A February 2025 research discovered that when homeowners engaged in relaxed petting, cuddling or cradling of their cats, the homeowners’ oxytocin tended to rise, and so did the cats’ — if the interplay was not compelled on the animal.
The researchers monitored oxytocin in cats throughout quarter-hour of play and cuddling at dwelling with their proprietor. Securely hooked up cats who initiated contact akin to lap-sitting or nudging confirmed an oxytocin surge. The extra time they spent near their people, the better the increase.
What about less-cuddly felines? The identical research famous totally different patterns in cats with extra anxious or aloof attachment types. Avoidant cats (those that saved their distance) confirmed no important oxytocin change, whereas cats who have been anxious (consistently searching for their proprietor however simply overwhelmed by dealing with) had excessive oxytocin to start with.
Oxytocin of avoidant and anxious cats was discovered to drop after a compelled cuddle. When interactions respect the cat’s consolation, the oxytocin flows — however when a cat feels cornered, the bonding hormone is elusive.
Perhaps people might be taught one thing from their feline mates on managing attachment types. The important thing to bonding with a cat is knowing how they impart.
Not like canines, cats do not depend on extended eye contact to bond. As a substitute, they use extra understated alerts. Probably the most well-known is the gradual blink. It is a feline smile, signaling security and belief.
Purring additionally performs a job in bonding with individuals. The low-frequency rumble of a cat’s purr has been linked not solely to therapeutic in cats themselves, but additionally to calming results in people. Listening to purring can decrease coronary heart fee and blood stress; oxytocin mediates these advantages.
The companionship of a cat, strengthened by all these little oxytocin boosts from day by day interactions, can function a buffer towards nervousness and despair — in some instances offering consolation on par with human social assist.
Are cats simply much less loving than canines?
It is true that research usually discover stronger oxytocin responses in canine–human interactions. In one extensively mentioned 2016 experiment, scientists measured oxytocin in pets and homeowners earlier than and after ten minutes of play. Canine confirmed a median 57% spike in oxytocin ranges after playtime, whereas cats confirmed a couple of 12% improve.
In people, oxytocin ranges rise throughout significant social interactions. Research present that contact with a cherished one produces stronger oxytocin responses than contact with strangers. So, a cheerful canine greeting is akin to that rush of seeing your youngster or associate.
Canine, being pack animals domesticated for fixed human companionship, are virtually hard-wired to hunt eye contact, petting and approval from us — habits that stimulates oxytocin launch in each events. Cats, nevertheless, developed from extra solitary hunters which did not want overt social gestures to outlive. So, they might not show oxytocin-fueled behaviour as readily or constantly. As a substitute, cats might reserve their oxytocin-releasing behaviour for after they actually really feel secure.
A cat’s belief is not automated; it have to be earned. However as soon as given, it’s strengthened by the identical chemical that bonds human mother and father, companions and mates.
So, subsequent time your cat blinks slowly from throughout the couch or climbs on to your lap for a purr-filled cuddle, know that one thing invisible is occurring too: oxytocin is rising in each your brains, deepening the belief and soothing the stress of day by day life. Cats, in their very own manner, have tapped into the traditional biology of affection.
