Do cats roar from the rear? Scientific American investigates feline fecal fumes and fart frequency.
Continuing its mission to probe the greater enigmas of the natural world, and knowing many of us must have pondered the question, Scientific American has set out to determine whether cats break wind.
In what it calls “an investigation into the mysteries of feline flatulence,” the magazine confirms that, yes, our furry friends do pass gas.
The good news? They are infrequent cheese cutters with minimal ass acoustics, particularly compared to the notoriously flatulent canines.
The bad news? When cats do fart, they are silent but deadly (SBD) affairs that deliver maximum olfactory potency due to the sulfurous mix of proteins and amino acids broken down by their digestive systems.
I can personally confirm that factoid, having been on the receiving end of a particularly insidious squeaker while Bud was sitting on my chest and nuzzling against my face. Once second I was rubbing the top of his head and telling him what a good boy he is, the next I was nearly gagging.
Farting is a normal biological function for cats, veterinarians told the magazine. While New York-based Cat Practice’s medical director, Eric Dougherty, says he doubts “anyone’s ever measured the exact quantity of cat farts in a scientific study,” you should have things checked out by a veterinarian if your little pal’s getting insane in the methane with concerning frequency.
“If you’re coming home and your cat is ripping farts every day,” Dougherty said, “you probably want to have it looked into.”
Same study, different interpretations
A few weeks ago we wrote about a Japanese study that found oxytocin levels spike in cats and their humans when they’re in close proximity.
The chemical – which is essential for bonding and often corresponds to positive feelings – rises in our respective bloodstreams when we’re interacting, the research team found.
Interestingly the effect is tied to distance, or rather lack of it. That means if your little buddy is bonded to you, you’re both at your happiest when you’re next to, or in physical contact with, each other.
The study didn’t find causation, just correlation, and the standard “we need more research” caveat absolutely applies here.

While the research team went to the effort of observing interactions in homes where cats live, and of testing cat and human urine samples for real data on biochemical levels instead of relying exclusively on questionnaires, the sample sizes were small. The team collected complete data on only 24 cats and 17 people.
It also found an unsurprising link between negative human moods marked by higher cortisol levels and stress in cats. That makes sense, as we’re extremely important to our feline friends. We’re the ones who care for, feed, shelter and love them, and they’re highly attuned to our emotions.
VICE, which ran a story on the study on Nov. 5, had a different take, claiming the study found “the oxytocin levels of humans and their cats appear to rise and fall in sync.” That’s not exactly what the paper describes, as negative human emotions were found to precipitate lower levels of oxytocin and higher stress hormones in cats. Again, the paper doesn’t establish causation, so we’re left to infer that our negative emotions are the catalyst without hard proof.
A handful of other publications published articles with interpretations similar to those of VICE, while a story by phys.org concentrates on the proximity aspect and notes that it could account for why different research teams have had varying results when trying to figure out whether having a cat leads to greater happiness.

The Likweli are only the fifth new primate species discovered in the last 75 years, and differ considerably from their closest cousins.
Deep in the jungles of the Congo basin, in an area wild and dense with trees and verdant undergrowth, crickets sing.
And cutting into their song, coming from high in the jungle canopy, are deep croaks, but they don’t come from frogs.
The source of the mysterious calls are a new species of monkey called the Likweli by the few locals who are aware of them. Likweli are rare, difficult to find and live between two rivers – the Lomami and the Lilo — about 1,200 kilometers from their closest relatives, the colobus angolensis. (Commonly known collectively as colobus monkeys, they are split into six subspecies.)
Likweli have short black fur like their cousins but differ in the color of their mouths and noses, which range from a beige cream to a tangerine-like hue, as well as the shape of their skulls and their deep, rhythmic, croak-like vocalizations.
They’re only the fifth new primates species discovered in the last 75 years, and the excitement at their discovery has been tempered with concern that they may already be endangered.
It took substantial effort to find, observe and take DNA samples from Likweli, scientists say, and there hasn’t been an opportunity for assessing their numbers yet. However, because Likweli live in a relatively small range and depend on the high canopy to thrive (they eat a diet of mostly leaves and live above most potential predators), they’re vulnerable.
Members of the team who found them published a study this week in the open-access journal Plos One.
The process of tracking, photographing, studying and testing the new species took almost 20 years, according to the study’s authors.
“The first evidence of the new species came in 2008 during exploration of the Lomami Basin by members of the Lukuru Foundation, in an area that later became Lomami National Park. Ashley Vosper and Bernard Ikembelo photographed an unidentified monkey in a high forest canopy on the east bank of the Lomami River in the Courbure Sector, named for six large meanders of the Lomami River,” they wrote. “Although the photograph revealed only part of the animal, the field team strongly suspected that this was not any of the monkey species they already knew from the region. Following the initial sighting, nothing more was reported until November 2018, when Jean Pierre Kapale led a surveillance patrol in the Courbure Sector and photographed a black monkey with pale markings around its mouth and a white perianal patch. These characters were unlike those of any known primate species in the area.”
They were able to find and photograph seven more monkeys before beginning efforts for observational study. Likweli live in small family groups of about six individuals on average, they found.
The discovery is a reminder that our beautiful planet is still capable of surprising us even at a time when human behavior and expansion has placed unprecedented pressure on animal species. It’s a reminder that our planet is irreplaceable, that life continues to find new expressions and niches to branch into, and we shouldn’t give up on it.
No matter what the Elon Musks of the world say, no matter how many renders they share depicting grand cities in domed Martian craters or clinging to the underside of Europa’s thick ice crust inside its subsurface oceans, there is only one place thst is absolutely perfect for us, that we evolved to live on and care for.
Even if the science fiction futures that Musk, Bezos, Thiel, Altman and company envision ever come to pass, even if science fiction technology like terraforming becomes reality, there is no backup. Earth, its fauna and flora are ours to protect, a responsibility we need to take seriously for the collective future of every kind of life that exists here.
Let’s hope the Likweli and all species that follow have a place to thrive.
That’s easy: first contact with an alien civilization.
I’m a space and science fiction fanatic. I mainline science fiction novels, keep tabs on the latest discoveries via the JWST, and I think about what’s out there probably more than I should.
There’s a burning desire in our hearts — for some of us, at least — to know for sure that we’re not the only ones, that humanity is not alone in a cold, lonely and infinite universe.
The events of 2026 are testament to that desire to know. Between the government release of UFO-related documents, former government employees coming forward with tall tales of crashed ships of non-terrestrial origin, and the return of Steven Spielberg to the director’s chair for another film speculating about what’s Out There, we’ve been thinking about aliens quite a bit collectively.
As for that central question, I’m not talking about simple cellular life. I don’t think you can find an astrophysicist, astrobiologist, astronomer, evolutionary biologist or anyone in a tangentially related field who honestly thinks life is unique to our planet.
The more relevant question is whether we are the sole sapient species, the lone civilization in our galaxy.

Think about the numbers: There are an estimated 300 billion star systems and trillions of planets in the Milky Way! Life has had a lot of places to evolve.
The Fermi paradox
That was the point the physicist Enrico Fermi made in 1950, when he had a now-famous lunchtime conversation with fellow scientists at Los Alamos. Probability alone indicates the galaxy should be teeming with life.
So, he asked his colleagues, where is everyone?
It’s now known as the Fermi paradox, and it’s guaranteed to come up in almost every conversation about the possibility of intelligent aliens. With so many star systems, planets and moons, surely some other species took an evolutionary path toward intelligence.
It’s a bit more complicated than that, of course. In a universe that is 13.7 billion years old, there has been enough time for innumerable species to evolve and fade, for countless empires to rise and fall. That means the question is “When is everyone?” just as much as it’s “Where is everyone?”
The truth is we’ve only been looking in earnest for about half a century. It’s only in the last four or five decades that we’ve had telescopes like the Hubble, Spitzer, Kepler and James Webb, which have revolutionized astronomy by giving us views we could previously only dream of.
It was only in the 90s that astronomers pointed the venerable Hubble at a black, seemingly empty patch of space, took a two week exposure and changed our understanding of the cosmos forever when the resulting image showed some 10,000 galaxies that were too faint to see before.
That patch covered only 2.6 arc minutes, or 1/24 millionth of the sky!

Despite what we’ve learned, we’ve barely begun the search for other intelligent civilizations.
Drawing any conclusions from our efforts so far would be like organizing a manhunt, then calling it off five seconds later because the suspect hasn’t been caught yet. Fifty years is nothing when scouring the cosmos. It’s less than an eyeblink of an eyeblink on a galactic scale.
Looking in the wrong place
As for the idea that aliens have visited us, that they crossed the interstellar void to etch patterns in our crops, delight stoners with light shows and evade every camera on the planet except for low resolution bricks from the dawn of the cell phone era, I’m not buying it. Neither should anyone else. Likewise for the claim by the JD Vances of the world insisting alleged UFOs are “demons” sent to torment us.
As Carl Sagan said, extraordinary claims require extraordinary evidence, and it is abundantly clear that the UFO enthusiast community can only offer blurry images not because of a lack of high resolution cameras, but because high res photos of the “phenomena” reveal they are mundane objects. They only become strange spacecraft when you blur them and squint.
Bird. Insect close to the camera. Exhaust plume. Debris. Visual artefact. Maybe. Proof of aliens? Absolutely not.
But there’s another, more important reason why aliens are not joyriding through our skies: if aliens are out there, there simply has not been enough time for them to become aware of our existence, let alone travel here.
Even light is “slow” on a galactic scale
As most of us know, when we look at the stars we’re seeing them as they were in the past, not as they are now. That’s because the distances between stars are so mind-bogglingly great that even light, which moves faster than anything in our universe, takes ages to cross the void.
The same limitation applies for anyone who might be looking in our direction from somewhere else in the galaxy. They see our star system as it was, not as it is. They see a silent star system without signs of an intelligent civilization.
Starliners and generation ships are popular concepts in science fiction for interstellar journeys that can take decades, centuries or longer.
Our galaxy is more than 100,000 light years across, so let’s say an intelligent alien race exists relatively close by in galactic terms, at “only” 500 light years away.
We have been a technological civilization for only a short time and didn’t create signals powerful enough to reach beyond our star system until the 1970s, according to SETI. That means there weren’t technosignatures hinting at our presence until about 50 years ago.
As a result, the soonest our hypothetical aliens could become aware we exist is about 450 years from now. That is how long it will take light carrying information about our technosignatures to reach them.
If our hypothetical alien friends are looking in our direction (a massive if in a galaxy with 300 billion stars to analyze), and if they have highly advanced telescopes, they might detect us. If we imagine they’re friendly and they send a message saying “Howdy, neighbors! You’re not alone! There are wonders to discover and many civilizations to meet out here!” it would take another 500 years for the message to reach us.
That means we wouldn’t know anything until around the year 3,000, if we survive that long without blowing ourselves up. (That’s a real possibility, and things aren’t looking very promising right now.)
And again, that’s if hypothetical intelligent aliens exist in our immediate galactic neighborhood. If there’s an intelligent civilization that exists, say, 4,000 light years away — which is still not very far in galactic terms — the soonest we could hear from them is about 8,000 years from now. (Four thousand for them to detect our technosignatures, four thousand for their message to reach us.)
The point is, space is big. Ridiculously, incomprehensibly, stupidly vast. More than 99.995 percent of the galaxy cannot be aware of our existence yet, let alone travel here, because of the reasons explained above.
The distances between stars are so great that we cannot comprehend them as they are, because nothing in human experience compares. We can only understand them in the abstract. As terrestrial animals with short lives, we are simply not equipped to live or think on galactic timescales.
The sun’s location within the Milky Way galaxy. Not to scale.
To put this in context another way, our closest stellar neighbor, a volatile triple star system, is 4.3 light years away. Yet even with the most advanced propulsion systems currently available to us, it would take us more than 70,000 years to get there!
If we manage to crack fusion and humanity’s most brilliant engineers are able to fit a starship with a compact fusion reactor, the travel time to the nearest star becomes “only” about 7,000 years.
Understanding just how big space is, and how long it takes to travel between stars, goes a long way to explaining why we’re wasting our time and resources with a fruitless search for alleged alien craft in our skies.

So where does that leave us?
I believe that one day we will learn we’re not alone. By we, I mean our species. I really hope it happens in my lifetime, but for all the reasons explained above, that’s wishfull thinking. The universe doesn’t care what we want, and it certainly doesn’t change the geometry of space-time to accommodate the wishes of dreamers on Earth.
Alien: Friend or foe?
I don’t think we’ll have to worry about belligerence. If a civilization is capable of sending ships to us, there’s literally nothing in our inventory of meager, planet-based resources that could interest a species that advanced. They wouldn’t want to eat us, because our biology would not be compatible. The amount of energy our entire civilization can muster would be laughable to an interstellar species.
And as the physicist Michio Kaku has argued, there’s a very strong argument to be made that if a species is advanced enough that interstellar travel is relatively trivial, it would have long ago shed any tendencies toward tribalism, sectarian violence or inventing gods of the gaps. You simply cannot reach that stage of advancement if you’re wasting resources and your most brilliant minds on war and petty divisions. (Kaku knows that better than anyone. His mentor was Edward Teller of Manhattan Project fame.)
The more significant danger, as Kaku likes to say, is that we may be beneath their notice and we’ll get “paved over.” A civilization capable of building cosmic megastructures, for example, wouldn’t consult us any more than we’d consult ants before laying a six lane super highway over their ant hill.
Still, there’s always a chance we’ll encounter something like MorningLightMountain, the nightmare alien intelligence from Peter F. Hamilton’s incomparable novel Pandora’s Star. The problem with MorningLightMountain wasn’t that diplomacy failed. There was no disagreement over resources or territory. Humans didn’t threaten it.
Rather, the alien’s psychology was so different from ours that it could not understand the concept of allowing other life to exist in the galaxy. No amount of discussion or attempts to persuade it would have made a difference, so immediately upon learning of our existence it launched a genocidal war that forms the bulk of Pandora’s Star and its sequel, Judas Unchained, two of the most beloved books in the modern science fiction canon.
Still, I’d like to think there is a galactic fraternity out there, an informal alliance of intelligent species united by curiosity and the effort to understand our universe. Whatever’s out there is likely to take forms we can never imagine and think in ways that never occurred to us.
If one day we do make first contact, I hope the best of humanity will be our representatives. And on that day, I hope humanity will be awestruck by the wonder of the universe, realize that slaughtering each other over land or beliefs is insane, and finally become united as a species.
Or even better, finally united as the children of Earth. After all, Buddy has made it abundantly clear that if I come into possession of a starship, he gets the most comfortable seat on board and gets to drive. The latter ain’t happening, but as for the former, I’d be thrilled to explore the cosmos with my little pal.
We’ve made enormous mistakes in our reconstructions of prehistoric creatures, including dinosaurs and mammals. Would paleontologists of the future misinterpret the clues our civilization leaves behind?
Imagine if, far in the future, humanity has spread across a healthy swath of space, colonizing worlds across dozens of light years.
Academics at a prominent science institute, looking to learn more about the humble beginnings of our species, fund a scientific expedition to Old Earth, where radiation and toxicity have finally declined to a point which allows teams to poke through the ruins of our civilization.
As they piece together clues from the rubble, they find references to companion animals who have been domesticated while their wild counterparts continued on.
What does a cat look like? they wonder. Then they find the bones, beginning with a handful of incomplete skeletons…
Critics have long argued that our depictions of dinosaurs are like skeletons wrapped in flesh, with modern representations doing a poor job of representing complete animals. What if the paleontologists and historians of the future mistranslate a word like “fur” or don’t realize the skeletons of cats are the same furry creatures that were human companions?A tiger imagined as a semi-aquatic animal with scales instead of fur, and a skull interpreted in much the same way we interpret dinosaur skulls. “Surviving texts make clear the tiger was comfortable in water, and like its distant cousin the crocodile, would remain mostly submerged, looking for opportunities to ambush prey.”No fur, just musculature, as if an anatomy book of animals is one of the few texts to survive in hard copy.A cat with magnificent plumage: “Research shows felines engaged in elaborate mating rituals, using their vivid colors and patterns to demonstrate virility to females in heat.”Finally, a winged cat. Outlandish? Maybe. But what if of the scraps of mythology to survive is a statue of a manticore, or paleontologists discover the bones of a cat species mingled with those of a large bird that died alongside it in a tar pit? In our time we’ve accidentally invented entire species of dinosaurs by mistakenly matching skulls from one species onto the spines of others, or wildly misinterpreting clues in the body plans of new and unfamiliar creatures.
“Can’t find your keys, human? That’s terrible. I don’t know where they are, but perhaps I could recall that information if, say, there were treats involved. Take your time, I’m in no rush even if you are.”
A new study shows dogs and human toddlers are eager to help when their adult caregivers are looking for a missing item, but cats don’t seem to care.
The study, which involved running the same experiment for young children, dogs and cats in their own homes, made it clear cats were fully aware of what was happening and understood their humans were looking for the missing object.
They just didn’t care.
There was one notable exception, of course. If the missing items were important to the cat — a favorite toy, for instance, or a bag of treats — the felines were motivated to help search or direct their humans to the missing objects, the research team from Eötvös Loránd University in Hungary found.
But at all other times, feline observers were content to hang back and watch, even when they understood their humans were getting frustrated.
By contrast, young children and dogs actively tried to help and signaled to adults when they thought they’d found the object.
“Lookin’ for something? No, I’ll just watch, thank you. Warm, warmer…oh! Cold…colder…that direction doesn’t look promising, human.” Credit: Gord Maclean/Pexels
So does this mean cats are jerks? Probably. Are we surprised by the results? Not at all.
We still love our furry friends, who do have their own unique ways of demonstrating they care about their humans beyond seeing them as providers of food, shelter, and safety, as well as playmates, minions and servants.
Besides, testing whether dogs or cats were helpful or not wasn’t the point. As the authors note, “[t]hese three species provide an important comparison because they share a similar anthropogenic environment but differ in their ecological and evolutionary backgrounds.”
In other words, they’re interested in figuring out how evolution plays a part in how species behave in particular situations. Although it’s yet to be conclusively proven for this behavior, a likely reason is because domestic cats are the descendants of a mostly solitary wildcat species, whereas we humans and our canine friends have long evolutionary histories of living in social groups and cooperating with each other.
The study is included in the March 2026 issue of Animal Behavior.
