Cats Have 276 Facial Expressions
Cats have a status for being inscrutable and unexpressive, however in response to a brand new research, that’s merely not true. Researchers discovered that cats, in actual fact, make 276 completely different facial expressions.
The analysis, printed in Behavioural Processes, demonstrated that cats have a wide selection of each pleasant and unfriendly facial expressions, belying the concept that cats should not social creatures. The research unpacks how cats work together with one another and with us.
Your Cat’s Face Can Inform You If They Are Feeling Pleasant or Not
Whether or not your cat is feeling pleasant (or not) towards one other cat is all proven on their face. One of many fascinating issues about home cats is that they exist on a spectrum, from solitary cats to those that dwell in small or massive social teams. In colonies of free-roaming cats, feminine cats cooperate with one another to boost their kittens. However housecats, relying partly on their adolescence experiences, could want to be the one feline, whereas others fortunately dwell with a number of cats. Given this variance, it is smart for cats to have facial expressions that inform different cats when they’re feeling pleasant—however scientists had not checked out it prior to now. It seems that cats have a a lot wider vary of expressions than they’ve beforehand been credited with.
Brittany Florkiewicz, PhD, second writer of the research and an Assistant Professor of Psychology at Lyon School in Arkansas tells us, “We all know that cats are very social. What the outcomes of our research present is that to navigate completely different social interactions and completely different social constructions, they’re utilizing all kinds of facial expressions.”
The truth is, they discovered 26 completely different facial actions that have been used to make a complete of 276 mixtures. 46 % have been solely utilized in a pleasant context, 37 % in an unfriendly context, and the rest in each sorts of conditions. The variety of facial expressions may be very complicated—extra like chimps (with 357 documented expressions) than gibbons (with about 80).
“One of the vital attention-grabbing issues is simply the large number of these particular person muscle actions that they noticed throughout the interactions,” says Mikel Delgado, PhD, writer of the upcoming e book Play With Your Cat!: The Important Information to Interactive Play for a Happier, More healthy Feline, not affiliated with the analysis. “The truth is, there have been extra of those alerts with affiliative behaviours than the agonistic [unfriendly] ones!”
What Your Cat’s Facial Expressions Imply
There was all kinds of facial actions, and a few, taken individually, didn’t essentially imply the cat was pleasant or unfriendly. However there have been eight particular actions that clustered collectively into two distinct teams: a set of feline facial actions related to friendliness in the direction of one other cat and a distinct set of actions related to unfriendly interactions. To know if an expression is pleasant or not, ear actions are one key signal to search for, however it’s additionally vital to note the eyes, whiskers, and tongue (see record beneath).
This builds on different indicators that earlier analysis has proven we must always search for in pleasant cat-cat relations, just like the tail-up sign (the tail straight up, usually with a little bit hook on the finish) or cats rubbing on one another, mendacity collectively, and selecting to spend time in shut proximity.
Nonetheless, the research discovered that there was no distinction within the complexity of affiliative and non-affiliative facial expressions; in different phrases, there have been no variations within the variety of facial muscle groups concerned in every kind of sign, pleasant or in any other case.

Play Face
A few of the pleasant interactions that have been recorded within the research concerned cats enjoying with one another, and that led to a different thrilling discovering: cats have a selected facial features associated to play, generally known as play face. This has beforehand been present in different mammals like canine, people, monkeys, apes, and solar bears, and it was thought to exist in cats—however that is the primary time it has been clearly proven from a scientific perspective.
Throughout many mammals, play face entails the identical type of facial muscle groups. In canine, these expressions can differ in depth, however basically, the lips are parted, the corners of the lips are pulled again, the jaw is relaxed, and the mouth is open. That is typically accompanied by panting or a sound like human laughter. It seems that cats, too, have an analogous play face that may differ in depth and be accompanied by related sounds.
“Play faces are actually helpful as a result of play is nice for the event of cognitive skill, social skills, and fine-tuned motor expertise, so having the ability to play has a lot of advantages,” says Florkiewicz. “However it’s additionally doubtlessly dangerous as a result of play can all the time go south, proper? You realize, if a cat will get a little bit bit too into the play bout, perhaps there’s a little bit bit an excessive amount of tough and tumble… So play faces are nice as a result of they assist cats to modulate play when it comes to altering depth and when it comes to altering the behaviours, going from tough and tumble to chase and vice versa.”
It’s actually attention-grabbing that cats appear to share a typical play face with different species and that they use it in an analogous approach. She hopes to be taught extra in regards to the feline play face in future analysis.
The existence of play face provides us an additional signal to search for to inform if cats are enjoying or preventing, one thing that folks with a multicat dwelling usually discover complicated.
“I’d say the fast and straightforward technique to inform them aside,” says Delgado, “is de facto, simply, are they screaming or is it largely simply quiet, as a result of play does are typically very silent and preventing just isn’t a nice sound.”
Different indicators that point out cats are enjoying embody function reversals in play (for instance, the cat who’s chasing turning into the cat who’s chased), modifications in exercise (comparable to from wrestling to chasing), and no overt indicators of preventing (claws in!). A few of the actions you would possibly see in cat-cat play embody a side-step with an arched again and the tail curled up, one cat mendacity belly-up with all their legs pointing up, a bouncy working gait, and a face-off during which one cat sits going through the opposite with a paw raised and transferring in the direction of them.
Feline Facial Expressions and Domestication
This research posited that these feline facial expressions—and the flexibility to supply them—should have advanced for a purpose. Home cats are much more social than their wildcat family, and so they interact in varied social behaviours, comparable to grooming one another, rubbing their heads collectively, resting collectively, and enjoying collectively. When animals (together with cats) are domesticated, they don’t simply turn into extra tolerant of individuals, additionally they turn into extra tolerant of one another as a result of they should share house. It’s potential that cats’ massive number of pleasant facial expressions has developed on account of the domestication course of, despite the fact that they’ve solely had a brief domestication interval (round 10,000 years).
“It is perhaps attributed to the truth that cats have turn into very socially tolerant and affiliated with each other, and so they’re utilizing facial expressions to navigate social interactions,” says Florkiewicz. In analysis that she and her group have accomplished, in addition to research from different researchers, she says that domesticated animals have extra complicated social lives, which in flip means they’ve completely different facial expressions.
Whiskers are an extremely good indicator: Content material or blissful cats nearly all the time level their whiskers ahead.
How They Did The Research
The information was collected on the CatCafé Lounge in Los Angeles over a interval of 10 months. The primary writer of the analysis, Lauren Scott, was an anthropology scholar at UCLA on the time (she’s now a medical scholar on the College of Kansas College of Drugs). Scott recorded cats on video after hours when all of the folks had gone dwelling. The cats have been filmed within the two principal rooms of the café—the lounge and the catio—the place the cats have been capable of transfer round and mingle with one another as they wished. In complete, 27 feminine and 26 male home shorthair cats took half within the research, with 688 facial alerts to different cats recorded over the ten months.
As soon as the info was collected, it was analyzed utilizing a system known as catFACS (cat Facial Motion Coding System). It’s a must to be taught a whole lot of feline anatomy to have the ability to use catFACS. The evaluation simply checked out facial alerts aimed toward one other cat; issues like respiration, yawning, and transferring the top didn’t depend. The scientists seemed intimately at facial actions comparable to ears ahead, nostril lick, half blink, and so forth.
Florkiewicz has even seen these indicators at dwelling after including a second feline to her family. “When my cats have been first launched to one another and have become extra pleasant over time, you discover that the ears are going ahead, the whiskers are going ahead, and the eyes are closing,” she mentioned. “They’re purring, they’re rubbing one another. It’s very clear that they’ve relationship. You’ll be able to see that affiliation coming by way of with the facial features.”
This research tells us that there’s way more to feline faces than beforehand thought. The outcomes could also be helpful to shelters, veterinarians, and cat guardians. For instance, having the ability to spot these facial expressions would possibly assist a shelter know whether or not a specific cat must be adopted out on their very own or to a house with one other cat. Most of us don’t have the time or inclination to review the catFACS, however all of us will pay extra consideration to our kitties’ facial expressions. In a multi-cat dwelling, it would assist us to know the way pleasant the cats truly are with one another.
This analysis just isn’t the one new improvement in studying find out how to learn cats’ faces. Lately, scientists have developed a feline grimace scale which identifies the facial actions related to acute ache in cats. Cat guardians and veterinarians can now reference the facial grimace scale web site or obtain the app and use it to see if there are indicators of ache on their cat’s face. This may also help veterinarians know when to prescribe painkillers for feline sufferers.
Sooner or later, the outcomes of the present research could result in a brand new device to assist folks learn their cat’s expressions. “I’m not going to be shocked if, within the close to future, you’ll be able to feed a video or photograph of your cat to an app that may enable you establish a few of these facial actions that AI can in all probability establish simpler than we are able to,” says Delgado.
