Cats might have a status for independence, however rising analysis suggests we share a novel reference to them — fueled by brain chemistry.
The primary chemical concerned is oxytocin, usually known as the love hormone. It is the identical neurochemical that surges when a mom cradles her child or when mates hug, fostering trust 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 relax.
Scientists have lengthy identified that pleasant interactions trigger oxytocin release in each canines and their house owners, making a mutual feedback loop of bonding. Till just lately, although, not a lot was identified about its impact in cats.
Cats are extra refined in exhibiting affection. But their house owners usually report the identical heat emotions of companionship and stress reduction that canine house owners do — and research are more and more backing these stories up. Researchers in Japan, for instance, reported in 2021 that transient petting periods with their cats boosted oxytocin ranges in many homeowners.
In that research, ladies interacted with their cats for a couple of minutes whereas scientists measured the house owners’ hormone ranges. The outcomes urged 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 is not simply due to the smooth fur. The act of petting and even the sound of purring can set off oxytocin launch in our brains. One 2002 study 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 released between cats and humans?
Research is pinpointing specific moments that cause the release of this hormone in our cross-species friendship. Gentle physical contact seems to be a prime trigger for cats.
A February 2025 study discovered that when house owners engaged in relaxed petting, cuddling or cradling of their cats, the house owners’ 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 house with their proprietor. Securely hooked up cats who initiated contact similar to lap-sitting or nudging confirmed an oxytocin surge. The extra time they spent near their people, the higher the enhance.
What about less-cuddly felines? The identical research famous totally different patterns in cats with extra anxious or aloof attachment kinds. Avoidant cats (those that saved their distance) confirmed no vital oxytocin change, whereas cats who have been anxious (consistently looking 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.
Possibly people may study one thing from their feline mates on managing attachment kinds. The important thing to bonding with a cat is knowing how they impart.
In contrast to canines, cats do not depend on extended eye contact to bond. As a substitute, they use extra understated indicators. Probably the most well-known is the gradual blink. It is a feline smile, signaling safety and belief.
Purring additionally performs a task in bonding with folks. The low-frequency rumble of a cat’s purr has been linked not solely to therapeutic in cats themselves, but additionally to calming effects in humans. Listening to purring can decrease coronary heart charge and blood stress; oxytocin mediates these benefits.
The companionship of a cat, strengthened by all these little oxytocin boosts from day by day interactions, can function a buffer in opposition to nervousness and despair — in some cases offering consolation on par with human social help.
Are cats just less loving than dogs?
It’s true that studies generally find stronger oxytocin responses in dog–human interactions. In one widely discussed 2016 experiment, scientists measured oxytocin in pets and house owners earlier than and after ten minutes of play. Canines confirmed a median 57% spike in oxytocin ranges after playtime, whereas cats confirmed a few 12% improve.
In people, oxytocin ranges rise throughout significant social interactions. Studies present that contact with a beloved one produces stronger oxytocin responses than contact with strangers. So, a contented canine greeting is akin to that rush of seeing your baby or accomplice.
Canines, being pack animals domesticated for fixed human companionship, are almost hard-wired to hunt eye contact, petting and approval from us — habits that stimulates oxytocin launch in each events. Cats, nevertheless, advanced 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 computerized; it have to be earned. However as soon as given, it’s strengthened by the identical chemical that bonds human dad and mom, 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 method, have tapped into the traditional biology of affection.
