Once again, we’ve underestimated cats. There’s so much more to the ways in which they communicate than we realize.
We know cats use non-verbal signals to communicate with each other, but recent research suggests we may just be scratching the surface, glimpsing only a portion of the information that passes between our furry friends.
Cats “talk” to each other by the way they position their tails, whiskers and ears, in addition to their overall body language.
It turns out there’s more. A group of interdisciplinary scientists from universities in Kansas, Arkansas and Haifa, Israel, found cats also employ specific facial expressions, and rapidly mirror each other’s expressions during play time to signal they’ve got good intentions and aren’t going to hurt each other.
From there, the coders and mathematicians on the team created an algorithm to record and sort the facial expressions the cafe cats used, employing CatFACS (Cat Facial Action Coding System) to associate each expression with its meaning.
The problem is, we humans are terrible at reading them. Even veterinarians trained in CatFACS still struggle to get it right, but happily this is precisely the sort of task algorithmic AI excels at. Like facial recognition software, a well-trained machine learning algorithm can recognize faces and record them more accurately and much faster than any person could.
In a column praising the facial expressions study, evolutionary biologist and Jane Goodall Foundation ethics board member Mark Bekoff said it’s the kind of labor-intensive work that truly advances our understanding of the ways animals communicate.
For cats and their human caretakers, Bekoff notes, it could help us reduce inter-species misunderstandings and make it easier to read our cat’s emotions, so we know when they’re not feeling well or need something.
“There are no substitutes for doing what’s needed to learn about the nitty-gritty details of how animals communicate with one another in different contexts,” Bekoff wrote. “This study of play opens the door for more widespread comparative research focusing on how animals talk to one another.”

We also know adult cats very rarely meow to each other, and the meow is reserved for cat-to-human communication. Imagine the frustration our little friends must feel when they have so much to tell us, but the only thing we understand are vocalizations — meows, chirps and trills — that can convey only basic ideas at best.
Cats aren’t equipped to use human language and there’s nothing wrong with that. Our feline friends already go to great lengths to communicate in ways we can comprehend. The least we can do is meet them halfway.
I would love it if my cat could talk to me.
Sure, he never shuts up, but if he could speak English I’d know why he meows at the same spot at the same time every morning, or what he wants on the occasions when he’s still meowing insistently at me despite the fact that his bowls are full, his box is clean, he’s had his play time, and every possible need and want of his — that I can fathom — has been met.
Most of all, I’d really like to know he understands I’ll be back soon when I go away for a few days, and my (mostly ignored) pleas for him not to attack his long-suffering, way-too-kind sitter.
Alas, Bud cannot speak. No non-human animal has ever demonstrated even basic proficiency in human language. People will point to examples like Koko the Gorilla and Nim Chimpsky, but there’s a reason why funding dried up for that kind of experiment.
It doesn’t work. It never did.
The scientists who end up taking on dual roles as researchers and parents to the animals invariably serve as interpreters, get too close to their subjects and swear that a gorilla pounding shiny buttons for “food tree food submarine” means the ape wants to have a picnic next to the ocean, or “car fly house car star” means she wants to ride a Tesla Roadster to Mars and start a colony with Elon Musk.
Koko, Nim, Chantek and the other apes who were the subjects of decades-long attempts to humanize them — and teach them language in the process — were ultimately not much different than Clever Hans the horse, who was reading subconscious nonverbal cues from his owner and convinced tens of thousands of people that he could do math and understand spoken language.
Hans had scores of experts fooled until the German psychologist Oskar Pfungst figured out how the horse was coming up with the correct answers.
Regardless of which famous example we’re talking about, no animal has ever mastered syntax, and the best that could be said of their proficiency with language, or lack of it, is that they learned they’d get attention and food when they pounded on a talking board or approximated a word in sign language.
Even if non-human primates were able to learn a handful of words by frequently reinforced association with an object, there has never been any evidence that they are actually using the words as language rather than simply understanding “Pushing the button that makes this sound means I get a treat!” (And yes, there is a profound difference. The former reveals the presence of cognitive processes while the latter is a conditioned response.)
Despite decades of intense effort, no animal has ever demonstrated the ability to use human language. At best an animal bangs on a few buttons and people are left to speculate on the intent. Maybe Fluffy likes the way a certain word sounds. Maybe it’s just fun to hammer on buttons the way it’s fun to pop bubble wrap. Most likely, these cats and dogs know that using a talking board is a guaranteed way to get attention, a treat and a head scratch from their caretakers.
Influencers and their talking boards
TikTok, which spawns inane trends with the reliability of an atomic clock, has provided a platform for people who insist their cats and dogs can talk. Using “talking boards” — elaborate set-ups in which words are assigned to their own buttons — they “teach” their cats how to express themselves in English and provide proof in the form of heavily edited, out-of-context clips that require the same sort of creative interpretation pioneered by Penny Patterson, Koko’s caretaker.
Seriously?
I just watched a video in which a woman claims her cat, named after Justin Bieber, was describing an encounter with a coyote by stomping on buttons for “stranger,” “Justin,” “Mike,” and “stranger.”
The woman says she thought Justin was asleep at the time, but now she believes the orange tabby saw the coyote outside and was still stressing about it well into the next day.
While she’s repeating Justin’s “words” back to him, two of her other cats come by and step all over the talking board. I guess whatever they had to say wasn’t important.
Justin’s talking board has 42 buttons, which stresses credulity well beyond the breaking point. More than half of the buttons are used for abstract concepts.
But forget all that for a moment and ask yourself how our own efforts to decode the meow have been going.
Despite our status as intelligent, sapient animals, despite the powerful AI algorithms at our disposal, despite the benefit of being able to digitally record and analyze every utterance, we haven’t come close to a reliable method for interpreting feline vocalizations.
Likewise with dolphins, whale song, corvid calls and the sounds made by other animals at the top of the cognition pyramid.
Mostly, we’re learning we’ve underestimated the complexity of our non-human companions’ inner lives, especially when it comes to the kind of multi-modal communication humans also engage in, but only subconsciously. We say what we want with our mouths, while our eyes, facial expressions and body language say what we’re actually thinking.
Likewise, the meow is an unnatural way for cats to communicate, and it contains only a fraction of the information cats are putting out there. It’s just that we can’t reliably read feline facial expressions, let alone tail, whisker and posture. (Studies have shown most of us, even when we live with cats, don’t get measurably better at this. In fact, we’re often no better than people with limited feline experience, but we think we’re better.)
Putting the burden on our furry friends
If we can’t crack a simple and limited system of vocalizations, aren’t we putting unrealistic expectations on cats? The average person has a vocabulary of tens of thousands of words, yet somehow we expect cats can latch on to an arbitrary number of them, approximate mastery of syntax that has eluded even our closest cousins, and bridge a cognition gap we haven’t been able to bridge ourselves.
It’s all too much.
I’ve had Buddy since he was eight or nine weeks old, and in more than nine years I still don’t know why he makes this praying motion. We may be best buds, but some things just don’t translate.
There’s a simple truth at the heart of this: Cats did not evolve to speak or parse human language, and that’s perfectly fine.
The little ones already meet us more than halfway because they understand we are hopelessly incompetent at reading tail, whisker or body language, and they understand we communicate with vocalizations.
By forgoing their natural methods of communication in favor of ours, cats are already taking on most of the burden in interspecies communication. Asking them to do more than that, to learn many dozens of words and the rudimentary rules of language, seems like laziness, wishful thinking or insanity on our part. Pretending that certain cats are successful is an exercise in the same kind of cynical opportunism that fuels every other desperate attempt by people trying to turn their pets into influencers. People do it because the reward is money and attention.
Worse, it contributes to the spread of misinformation. TikTok’s talking board videos routinely net millions of views, converting a credulous audience into an army of true believers who are convinced that, with just a little effort, their feline pal can shoot the shit with them.
If people want to construct elaborate talking boards in their homes and pretend their cats are expressing themselves in English, who am I to object? It’s not the smartest use of time, but have at it. What I won’t do is participate in the delusion that felines are a few buttons away from being able conversation partners, nor will I pretend these efforts have any relationship to science.
So to the journalists who keep writing credulous stories about these supposedly talking animals: please familiarize yourself with the example of Clever Hans, and please, I beg you to stop promoting these videos as if they’re anything more than wishful thinking. You are doing your readers a disservice for the sake of a few clicks.
Note: Jackson Galaxy isn’t a fan either, saying he’s “got some serious problems” with the talking board trend. Calling it “problematic,” he points out that cats are not only partially domesticated and the only animal species in history to take that step without human prompting, but humans have never selectively bred cats for specific behaviors or to bring out intelligence traits as we have with canines. (Think of sheep dogs or retrievers, who are the products of thousands of years of breeding for well-defined tasks.) There simply hasn’t been a need to breed cats for behavioral traits since the thing humans traditionally valued most about them — their ability to reliably eradicate rodents and protect human foodstuffs — is innate. No one had to teach cats how to hunt or breed them for the task. It’s only in the last two hundred years or so that certain human societies began breeding cats, and they did so for aesthetic attributes like coat patterns. Galaxy also notes that animals do not express emotions the same way humans do. Like monkeys, who “smile” when they’re terrified, felines express joy, anger and fear with their tails, whiskers, ears and body language. It’s not in their nature to tell us they’re happy or scared by padding up to a contraption and hammering on a button.

Think you can decipher the rhythmic clicks and whistles of dolphins or the grunts and alarm calls of monkeys? A foundation is offering big prizes for progress in communicating with animals.
Looking to prompt renewed efforts at decoding animal communication, a non-profit founded by an investor and a university are offering prizes — including a hefty $10 million — to teams that can figure out what animals are “saying.”
Entrants aren’t asked to come up with a Star Trek-like “universal translator” for animals. Rather, the people behind the Coller Dolittle Challenge want to see methods that allow for two-way communication between humans and individual species.
“We are open to any organism and any modality from acoustic communication in whales to chemical communication in worms,” said Yossi Yovel, a professor at Tel Aviv University and co-chairman of the challenge.
The grand prize is a $10 million grant or $500,000 in cash, chosen by the winner, while the Foundation will offer $100,000 prizes each year for the best entries that make significant progress toward communicating with animals. The yearly prizes will be assessed “for significant contributions to decipher, interface or mimic non-human organism communication.”
While it may seem far-fetched — and there are those who believe humans will never be able to fully understand animal communication in proper context — there have been efforts to communicate with and decode the communications of bats, dolphins, whales and some primate species. Scientists have also pushed the boundaries on understanding group communication, such as the coordination involved in avian murmurations.

The organizers believe artificial intelligence will be the tool that ultimately helps crack the communication barrier, but entrants aren’t required to use AI. The technology is incredibly useful for tasks involving pattern recognition and sorting large amounts of data, both of which are important in this kind of work when researchers are tasked with analyzing thousands of audio samples or hundreds of hours of footage.
Alas, we don’t think the foundation will be interested in the Buddinese language, which boasts 327 different ways of demanding food and features a timekeeping and calendar system based on meals and naps. A short trill followed by a series of staccato meows, for example, means “I expect prompt service at salmon o’clock,” while a truncated meow ending with a scoff is used to indicate displeasure when a human napping substrate tosses too much during sleep.
Still, maybe we’ll dress it up to make it look properly academic and give the challenge a try. Those prizes could buy a lot of Roombas!
By unlocking the mysteries of how sperm whales communicate and demonstrating their impressive cognitive abilities, researchers hope to get people invested in the fate of these endangered animals.
Sperm whales are chatty.
Their language is markedly different from the deep cetacean moans associated with other whales, taking the form of Morse code-like clicks that boom through the ocean in a decibel range almost twice that of jet engines.
And while we’ve long known animals like monkeys assign specific meaning to short vocalizations varying from alarm calls to affirmations of social rank, sperm whale conversations can endure for an hour or more, with participants exchanging complex strings of clicks that vary depending on context, environment and even which pod family is speaking.

While artificial intelligence has been maligned over the past few years as people grapple with its rapid progress and potential for abuse, it remains the best tool we have for teasing out patterns that our human minds can’t discern, especially from large quantities of data.
With more than 9,000 recordings of sperm whales, Project CETI — Cetacean Translation Initiative, a non-profit effort to decode and translate sperm whale communication — had precisely the kind of huge data cache that AI excels at analyzing.
By feeding the recordings into specially trained machine learning algorithms, the research team was able to identify a wealth of new language patterns. While human languages are composed of quantized morphemes — prefixes, suffixes and root words — whale communication is broken down into sequences of clicks and pauses called “codas.”
Like Morse code, codas make a distinction between short clicks and long clicks. Sperm whales also vary the tempo of the clicks, which could represent inflection, “dialects” or concepts completely alien to the human mind.
“Some of what they’re doing might be totally different from our way of communicating and we’re probably never going to be able to fully grasp those differences,” Oregon State postdoctoral marine researcher Taylor Hersh told NPR.

Researchers believe the “inter-click intervals” — akin to ghost notes in music — may be as significant as the clicks themselves. Importantly, while human ears were able to identify and catalog some of the codas, the machine learning algorithms found many that human analysis missed.
That’s not surprising considering sperm whales — the loudest animals on Earth, capable of generating sounds up to 230 dB — took a much different evolutionary course and, as ocean-dwelling creatures weighing up to 90,000 pounds (40,800 kg) likely have a radically different sensorium compared to humans.
The comparisons to music go further than ghost notes.
“This study shows that coda types are not arbitrary, but rather that they form a newly discovered combinatorial coding system in which the musical concepts of rubato and ornamentation combine with two categorical, context-independent features known as rhythm and tempo, by analogy to musical terminology,” CETI’s team wrote on May 7 while unveiling the most recent study.

While people have used many abilities to mark the dividing line between humans and animals over the years — including the ability to use tools, experience emotions, and demonstrate self-awareness — human capacity for authentic language with syntax and context-dependent meaning was one of the stalwarts, standing the test of time as new research toppled the other dividers by showing animals do indeed use tools, experience rich emotions and have complex inner mental lives.
With this research, scientists are assembling a “sperm whale phonetic alphabet” that will make it easier to discern and catalog whale codas.
To be clear, there’s still a lot of work ahead before scientists can prove sperm whale codas are comparable to human definitions of language, but whether they strictly meet that definition may not matter. After all, it’s clear the clicks and pauses of whale codas are imbued with meaning, even if it remains elusive to us for the moment.
Indeed, “sperm whale communication has both contextual and combinatorial structure not previously observed in whale communication,” the team wrote.
Proving sperm whale codas are tantamount to human language isn’t the goal anyway. The team has two overriding priorities — decode the meanings behind the codas, and get the wider public invested in the fate of these endangered animals by showing they’re not so different from us.
“Our results show there is much more complexity than previously believed,” MIT AI lab director Daniela Rus told NPR, “and this is challenging the current state of the art or state of beliefs about the animal world.”
As the supreme species on this planet, cats have a lot to lose if AI seeks to supplant them as Earthly rulers.
With artificial intelligence making rapid progress over the past year, we asked cats what they think about a future where we depend on intelligent machines.
