When being friendly does not seem to be enough
Have you ever wanted a cat to come closer and found yourself doing all the work? You speak gently, offer your hand, and wait for a response that may or may not arrive.
It is easy to turn that quiet moment into a judgment: this cat does not like people, or perhaps it simply does not like you. But before deciding what the animal feels, there is another question worth asking: what are you actually communicating?
A team of researchers at the universities of Sussex and Portsmouth investigated a remarkably small part of that exchange. They were interested in movements of the eyes, not treats, toys, or a particularly persuasive voice.
Their study, published in 2020, took a familiar observation from cat owners and put it through two experiments. The result offers an intriguing possibility for anyone who wants a gentler way to greet a cat, without pretending that affection can be summoned on command.
The most useful part is not a secret method for making every animal love you. It is the reminder that a greeting can be an invitation rather than a demand, and that the response may be quieter than the one you were waiting for.
A familiar expression became a research question
The behavior at the center of the study is commonly called the slow blink. It is not just the ordinary blinking that keeps an eye comfortable, and it does not require a cat to shut both eyes dramatically.
In the original Scientific Reports paper, Tasmin Humphrey and colleagues describe sequences of partial blinks followed by prolonged narrowing of the eyes or an eye closure. Those small movements are easy to overlook if you are watching only for a cat to walk over.
The first experiment recruited 21 cats from 14 households. Owners were shown how to perform the slow-blink movement, then took part in trials at home, where their cats were already familiar with the surroundings.
Once a cat had settled, an owner sat approximately a meter away and delivered the eye movements. In the comparison condition, the owner stayed in the room but did not interact with the cat.
That comparison mattered. A relaxed cat narrowing its eyes while its favorite person happens to be nearby would not, by itself, show that the person’s expression made a difference.
The researchers recorded the interactions and analyzed specific facial movements. After excluding three outlier pairs, the final analysis included 18 cat-and-human pairs.
Cats showed more eye narrowing and partial blinking in response to their owners’ slow blinks than during the no-interaction condition. Ordinary reflexive blinking did not show the same pattern, which helps explain why the distinction between a blink and a slow-blink sequence matters.
Still, an owner is not an ordinary visitor. Years of meals, familiar routines, and shared space could be part of any exchange between them, so the team had another question to investigate.
The unfamiliar visitor made the question more interesting
The second experiment recruited 24 different cats. This time, an unfamiliar researcher provided the facial expression, allowing the team to examine something beyond an established relationship with an owner.
The researcher either performed the slow-blink movements or adopted a neutral expression without direct eye contact. The cats were also offered a flat, upward-facing hand before and after the interaction, so their tendency to approach could be compared.
This was not a contest in which cats had to climb into a stranger’s lap. The researchers counted a movement of the head or body toward the offered hand as approach, movement away as avoidance, and no change as neutral.
That modest definition makes the result more useful, not less. A small movement toward somebody can be meaningful without becoming a dramatic transformation.
After exclusions, this experiment’s final analysis also included 18 cats. They showed more partial blinking and eye narrowing during the slow-blink condition, and their approach scores were higher afterward than after the neutral expression.
BBC Science Focus’s reporting highlighted that difference in willingness to approach the outstretched hand. The finding supports the idea that this small facial exchange can be part of positive communication between a cat and a human.
But the study contains a useful complication: the neutral condition involved looking slightly away. The authors acknowledge that gaze direction or the person’s apparent attention could have influenced the approach response.
That means the experiment does not isolate a magical eyelid movement from everything else happening between two living beings. It offers evidence worth noticing, with questions still attached.
A promising signal is not a translation device
Calling the expression a cat smile makes the finding easy to remember. Treating it as a literal translation of a human feeling would take the evidence too far.
The researchers suggested that slow blinking may function as positive emotional communication. They also said further work was needed before reaching firm conclusions about the emotional state associated with it.
They discussed several possible explanations. Cats might learn that people respond positively to the behavior, or the movement might have developed from interrupting an unbroken stare that could feel threatening.
Those are possibilities, not settled origin stories. Neither the paper nor a blink from your own cat can tell you precisely what that animal is thinking.
The samples were small, and the household setting introduced variation in distances, owner behavior, and other cues. The research did not test whether this greeting creates a lasting bond or repairs fear caused by unpleasant handling.
Keeping those limits does not spoil the warmth of the finding. It protects something important: the difference between being curious about an animal and deciding that its behavior must mean whatever would make us feel most loved.
A gentler way to offer a hello
The University of Sussex’s account describes a simple way to try the interaction: soften and narrow your eyes as you would in a relaxed smile, then close them briefly. The aim is a gentle expression, not an intense staring competition.
Choose a calm moment with a familiar cat, keep a comfortable distance, and leave the animal free to move away. There is no reason to interrupt sleep, corner a reluctant cat, or keep repeating the gesture until you get the response you wanted.
If the cat turns away or does nothing, let that be enough information for now. A greeting that leaves room for refusal is more respectful than one that becomes a test the animal has to pass.
Nor should an approach be treated as permission to scoop the cat up. Coming closer and wanting to be held are different things, and this research did not establish that one guarantees the other.
For the person hoping to connect, the practical payoff is small but real: you have something gentle to offer, and something subtle to watch for. You do not need to invent a story about rejection when the exchange stays quiet.
What changes when you stop measuring every friendly moment by whether the cat comes all the way to you? Sometimes the better beginning is simply learning how to say hello, then leaving space for the other participant to answer.
