The find is extraordinary, allowing scientists to directly study the extinct cat’s musculature, fur, head shape, and even its claws and whiskers.
A team in Russia stumbled on the find of the century when they located the stunningly well-preserved remains of a saber-toothed kitten in Siberia.
The kitten, which was found near the Badyarikha River in northeastern Siberia, was about three weeks old when it died, scientists estimate.
Unlike typical finds — a fang here, a mandible or partial skeleton there — this specimen still had its fur, claws, whiskers and muscles, which means scientists have already learned more about the species, Homotherium latidens, than they have with almost any other long-extinct animal.

While the saber-toothed cub is a true felid, it boasts adaptations unlike any surviving member of the panthera genus.
It has wide paws wrapped in heavy fur, a short tail and a stockier, lower-to-the-ground build than modern lions and tigers. Those adaptations, scientists believe, made it easier for Homotherium latidens to traverse environments with ice and heavy snow.
Its head shape is slightly different, with smaller ears than modern big cats, and its neck is enormous, more than twice as thick as the neck of a comparable three-week-old lion cub which was used for comparison. Likewise, its mouth is capable of opening significantly wider, although the team did not compare it to the jaguar, which has the widest-opening jaw among extant felids.

The frigid, arid clime of Siberia made it possible for the cub’s body to endure for so long. The team that made the discovery conducted radiocarbon dating that puts the cat at between 35,000 and 37,000 years old, according to reports.
It’s not clear how the cub died, although its species went extinct about 10,000 years ago, likely as a direct result of fewer prey animals in the frigid zones it occupied. Additional bones belonging to the rear of the cub skeleton were encased in a large cube of ice immediately next to the intact upper body.
The cub’s remains were recovered in 2020, but the results of the research team’s analysis were just released on Nov. 14 and published in the journal Nature. The paper’s authors have a lot more to share about the species’ physical characteristics, they noted in the text, and plan to follow up soon with a second paper going into more detail about what they learned from the cat’s intact musculature.

The strange footprint may date back as far as 35 million years ago, according to a preliminary analysis.
Before house cats, tigers and lions, before sabretooth cats and their scimitar-toothed relatives, Pseudaelurus (pseudo-cat) stalked the forests and plains of Europe, Asia and North America between eight and 20 million years ago.
Before Pseudaelurus, Proailurus — an animal whose name literally means “before cats” — stalked the Earth beginning 30 million years in the past.
Proailurus was thought to be the earliest true feliform ancestor, but now there may be evidence of a felid or feliform animal that predates both Proailurus and Pseudaelurus. Feliform is a term that encompasses cat-like creatures both extinct and extant, from familiar felines to civets and mongoose.
Deep in South India’s Nallamala Forest, near one of the country’s largest tiger reserves, members of the aboriginal Chenchu tribe found a fossil that could put the cat lineage back even further.
The fossil is well-preserved and clearly defined, made by an animal whose paw was about the size of an adult man’s hand. It bears a striking resemblance to tiger pug marks, but perhaps the most striking feature is its three toes.

“Based on the distinctive characteristics of the sandstone, identified as the Cuddapah subgroup Quartzitic sandstone, the estimated rock’s age is approximately 35 million years,” archaeologist Arun Vasireddy told the Times of India. “It was around this time that sandstones were formed and it is likely that the animal would have cast its prints.”
Biologists have had to reshuffle their picture of felid lineage many times over the past century and a half as new discoveries uncover previously unknown species of cats and cat-like creatures. Since they first appeared, cats have taken hundreds of different forms with significant variations in size, appearance, hunting methods and preferred terrain.
The experts aren’t popping the champagne yet. There’s a lot more work to do before they can declare a newly-discovered species or even offer more than educated guesses about its niche and appearance.
Nallamala Forest may yet hold more secrets, and research teams will look for additional prints as well as potential remains. It’s a process that will unfold over years and decades, perhaps even longer.
Still, it’s a tantalizing clue about the past and the origin of some of Earth’s most iconic animals.
In the meantime, Vasireddy said, “nothing can be said clearly until further research.”

Rumors of big cats in the UK countryside have persisted for years, with witness claims from all over the country. The latest reported sighting was in northern England.
People who really want to believe big cats are running around the British countryside are ecstatic with the news that a DNA sample from a dead sheep reportedly tested positive for panthera DNA.
The DNA sample was swabbed from a freshly-killed sheep carcass “at an undisclosed upland location” in Cumbria, northwest England, a witness told BBC Wildlife. It’s exactly the kind of countryside where people have been reporting big cat sightings for years, although the sightings aren’t confined to that area, with other witnesses claiming they’ve seen large felids as far as the UK’s southern coast.
Sharon Larkin-Snowden, who lives nearby, told a big cat enthusiast podcaster that she disturbed the “big cat” while it was feeding. The startled felid took off and jumped a stone wall, leaving the partially-eaten sheep, Larkin-Snowden said.
“I assumed at first it was a sheepdog, but then I did a double take and realised it was a black cat,” she said. “It was big – the size of a German shepherd dog.”
“I could really go for a Chinese! Anyone else wanna go for a Chinese?”
A swab was collected — the details are sketchy on who did the collecting and when exactly they submitted the sample — and sent to the University of Warwick’s Robin Allaby, a professor of life sciences.
Allaby, whose specialty is studying the genetics and evolution of domesticated plants, began offering a DNA testing service for the public some 12 years ago in response to the persistent rumors of big cats in the countryside. In the past samples have yielded DNA from foxes and other animals, but Allaby says this one matched the genetic profile of a big cat, although he cannot say which species.
It’s not unusual for a DNA sample to match to a genus, in this case panthera, but not to a specific species if the sample was degraded or only partial.
Rick Minter, who has made a career of tracking alleged big cat sightings across the UK, says he believes the mystery cat is a leopard. Leopards and jaguars are the only two big cats who have true melanistic color morphs — meaning some of them have virtually all-black coats — and Minter says he believes it’s more likely the former.
Neither are native to the UK or Europe: Leopards range from Africa to Asia, while jaguars range from south to Central America, with some populations edging slightly into the US.

Why isn’t a DNA match evidence of big cats in the UK?
If the lab results say the sample came from a big cat and that result is consistent with the witness account, what’s the problem?
Chain of custody, for one. We don’t know anything about who took the sample, where it was taken, the time elapsed between the kill and the sample swab, or who may have handled it before it reached Allaby.
In fact, we don’t know if there was a dead sheep to begin with.
If I were a prankster living in the UK, for example, and was friendly with a keeper at a local zoo, I could have the keeper swab an animal, bag it and hand it over to me. There are dozens of conceivable ways a person could obtain a sample even if they don’t know someone who works in a zoo.
“So we left the sheep there at the edge of the field and made sure the lady saw us before we buggered off over the fence. Next day, we was in all the papers! A right laugh that was, mate.”
The problem is the provenance of the sample and what happens to it between the time it’s collected and ends up in the hands of a scientist like Allaby.
This is why chain of custody is paramount in criminal trials, and why there must be a complete record of who handled samples from collection in the field to the lab. Even in the absence of foul play, an improperly handled sample can be contaminated and render test results meaningless.
It’s not a matter of trust, it’s the simple fact that extraordinary claims require extraordary evidence, as Carl Sagan was fond of saying. Short of capturing one of these animals or getting clear, indisputable footage, any other claimed proof has to be ironclad.
Speaking of footage, that’s another issue. It’s extremely difficult to believe that a breeding population of big cats can exist in the UK countryside for years or even decades without a single definitive photo or video. The UK’s rural areas may not be blanketed by CCTV cameras like London, but they’re not the Amazon either. People live, work and farm in those regions, cameras are more ubiquitous than ever, and farmers take steps to protect their livestock, including installing cameras.
Big cats don’t just feed and vanish into the mist. They mark trees with their claws and urine, they leave distinct pug marks, they leave distinctive bite marks on their prey, and they make noise. To paraphrase one naturalist, when big cats are living nearby, you know it. Even if you don’t see them, signs of their presence are ubiquitous.
To accept the claims of tigers, leopards and pumas gallavanting in the fields around small towns and villages, we’d have to suspend disbelief or conclude that these are some sort of previously unknown ghost cats who can fade in and out of the physical plane.
I’m not a skeptic to be a killjoy. If big cats really were running around the UK, that would be a hell of a story. But we’d still need convincing evidence, and this isn’t it.
Nicholas was orphaned and severely injured as a cub as he and his mother tried to cross a busy highway. He’s settling into his new home, where he will have his own habitat, den and even his own pond.
Nicholas the mountain lion has a beautiful home waiting for him with his own pond, a rock den, a grassy area where he can run around and several other little hideaways where he can enjoy some privacy and naps.
But first the three-year-old puma will have to clear quarantine and become more comfortable with his new surroundings and new caretakers.
“He’s doing really well but he’s still very scared, he’s a very timid cat, so we’re just taking it really slow, day by day and the keepers are taking some quiet time with him,” said Bobbi Brink, the founder of San Diego County-based Lions, Tigers and Bears, Nicholas’ new home.

The golden-coated feline with an expressive face has had a tough journey to the 93-acre sanctuary that will be his permanent home.
In 2020 when he was just a cub, Nicholas was following his mother across a busy highway when both were struck by a car. Nicholas was badly injured and his mom was killed in the collision, an unfortunately common fate for members of their species as their longtime habitats are increasingly fragmented by new developments and highways.
Because they require about two years with their mothers to learn how to survive on their own, it’s almost impossible to release orphaned pumas back into the wild. Unlike, say, the orphaned orangutans of Borneo and Sumatra, who can usually be taught to successfully fend for themselves because humans can show them how to physically manipulate their surroundings, there’s no way to teach orphaned pumas how to select prey, stalk, pounce and deliver kill bites.
A sanctuary in northern California provided a home for Nicholas for about three years, but recently went bankrupt, so the staff at Lions, Tigers and Bears secured him, prepared a habitat for him and took on the Herculean task of transporting him to San Diego County.
Nicholas’ case is even more complicated because he has lasting neurological damage from the car crash that killed his mother, including a pronounced head tilt that worsens when he’s scared.
Brink told PITB it’s normal for cats like mountain lions to be spooked by the commotion and uncertainty of a move, as well as leaving everything they know behind. Nicholas is simply obeying his wild instincts, which urge him to be guarded. But he’s got a loving team of caretakers who will work with him, as well as veterinary specialists who are well versed in caring for animals with neurological damage.
“Sometimes it can take (animals like Nicholas) a month, sometimes it can take three months to build up that trust,” Brink said. “His biggest need is he’s very afraid, so we’re gonna have to work around his fear so we don’t scare him more.”

While Nicholas will have his own habitat and can keep to himself as much as he likes, recent observations of his secretive species have shown that pumas have “secret social lives,” and Nicholas will have the opportunity to meet and interact with other mountain lions if he’s comfortable with it.
Pumas — which are known by the scientific name puma concolor and are also called mountain lions, cougars, panthers, catamounts, screamers, painters, gato monte and many other names — are among the most adaptable felids in the world and range from the southernmost edge of South America to just over the Canadian border. They’re able to thrive in mountains, tropical regions, deserts, forests, human-adjacent rural areas and even in urban population centers, as the famed “Hollywood Mountain Lion” P-22 did for more than a decade in Los Angeles.
Their ability to adapt has served them well in a changing world, but they’re not immune to the pressures of human expansion.
In California their habitats have been carved up by the state’s busy and deadly highways, leaving the cats in genetically isolated pockets. Pumas who strike out in search of their own ranges are extremely vulnerable to vehicle traffic. P-22 famously crossed several of the world’s busiest highways to reach his eventual home in LA’s Griffith Park, but others like Nicholas and his mom aren’t so lucky.
Solutions like the $90 million Wallis Annenberg Wildlife Crossing, currently under construction in Los Angeles County, can connect fragmented ranges and give pumas, coyotes, foxes, deer, rabbits and other animals safe passage. But experts point out that they are just one component in a long-term solution that must include more careful zoning, fences to funnel animals toward safe crossings, and options like tunnels that run under highways, since not all animals will use overpasses.
As planners and wildlife experts figure out new ways to ensure the survival of wildlife in an increasingly crowded, human-dominated world, sanctuaries like Lions, Tigers and Bears play a crucial role by caring for the innocent animals who are injured, displaced and rescued from bad circumstances.
