For the first time, humans have successfully returned orphaned tiger cubs to the wild after raising them and training them to hunt.
For more than 50 years, tigers were absent from Russia’s Pri-Amur region.
Sparsely-populated, mountainous and blanketed in forest, the domain borders the heart of the Russian Far East, offering hundreds of thousands of contiguous square miles for the most robust sub-species of Earth’s most magnificent predator.
Here, tigers can roam without fear of conflict with local farmers, or roads that carve up habitat and pose a danger to animals trying to cross. Prey is abundant, and adaptations for surviving in the local terrain are coded into the tigers’ DNA.
Now that scientists have proven for the first time that tigers can be successfully reintroduced into such an environment, big cat advocates imagine Russia’s Far East as a haven for the large felids. It’s a place where tigers can thrive, mate, reproduce and change the outlook for their species, which has dwindled to only 4,000 or so remaining in the wild.

The project to reintroduce Amur tigers to their native habitat is a cooperative Russian-American endeavor. The team started by building a tiger conservation center in the Amur oblast a decade ago.
The facility is built in a way that orphaned tigers can be raised and taught how to hunt without directly interacting with their human caretakers. That’s a crucial component, because tigers who see humans as potentially friendly or sources of food have drastically reduced chances of surviving in the wild, and are easier marks for poachers.
After 18 months, the cubs are brought to remote locations in Pri-Amur and released. Of the first group of orphan tigers released into the wild, 12 were able to survive on their own.
One gluttonous tiger failed: he crossed over the border into China and began eating domesticated animals, including 13 goats in what researchers called “a single event.”
The fattened tiger then retraced his steps to Pri-Amur, and when he didn’t show fear of humans, the team decided he had to go. They captured him and sent him to a zoo, where he gets all the free meals he wants and contributes to the captive breeding program helping his species maintain genetic diversity.
With 12 out of 13 tiger re-introductions successful, the program provides “a pathway for returning tigers to large parts of Asia where habitat still exists but where tigers have been lost,” said Viatcheslav V. Rozhnov, who leads the reintroduction project.

The successful reintroduction has also led to some surprising developments. Two of the cubs, Boris and Svetlaya, were unrelated but were rescued at about the same time and raised in the Russian orphanage for their species.
Using tracking devices they’d placed on the newly-released young tigers, the research team watched as Svetlaya settled into a home range and Boris made a beeline for her, “almost in a straight line,” crossing 200km (120 miles) of terrain to reunite.
The team’s hopes were confirmed six months later, when Svetlaya gave birth to a healthy litter of cubs, the first natural-born tigers to result from the reintroduction project.
Another tigress, Zolushka, also gave birth to a healthy litter when she was reintroduced in an area closer to a still-extant population of Amur tigers. The researchers believe the father was born wild in the region and was not part of the reintroduction program.
The wilderness in Pri-Amur and its environs is so vast, untouched and undesirable to human habitation that it could be home to generations of tigers, securing their future after so many decades of grim news for the iconic big cats.
“The grand vision is that this whole area would be connected,” Luke Hunter, executive director of the Wildlife Conservation Society’s Big Cats Program. “There’s lots of habitat that could be recolonized by tigers.”
This singular species of wildcat exists only on two islands and has evolved to live a semi-arboreal existence deep in the jungle.
While tigers, lions and domestic cats are the stars of the felid world and command the lion’s share (pun intended) of the attention, even from cat lovers, there are obscure species living in far-off locations where they’re rarely glimpsed by human eyes.
There’s the fishing cat, the black-footed cat and the sand cat, and then there are species that are obscure even among the obscure. The Sunda clouded leopard fits into that category, inasmuch as the unique felid can fit into any category.
Like orangutans, the Sunda clouded leopard can be found in only two places in the world: the Indonesian islands of Borneo and Sumatra. They’re faced with the same existential threat that has pushed orangutans dangerously close to extinction, which is the relentless destruction of old-growth jungle to clear land for more palm oil plantations.

Palm oil is coveted by multinational corporations in the food and cosmetics businesses, and it’s in everything from chocolate and instant noodles to lipstick and margarine, according to the World Wildlife Fund.
The problem with razing old growth jungle and forest is that it doesn’t just grow back. They’re extremely delicate ecosystems that have arrived at a natural balance over thousands of years, with every species of animal and plant contributing something vital to the vibrant tapestry of life the jungles host and support. You can’t just plant trees and usher animals to a new home. It would take hundreds of years for those new jungles to even superficially resemble the lifegiving old growth jungle.
There are heartbreaking images of shocked orangutans sitting in the ruins of their former homes, with nothing but the stumps of trees and dozer-trodden vegetation as far as the eye can see.
Those are the lucky ones. The loggers who work for massive multinational corporations aren’t bound by rules or ethics, and they won’t wait for animals to clear out before they destroy. They often shoot orangutans on sight regardless of whether the animals are carrying young.

That’s the primary reason why Borneo and Sumatra are now home to entire academies for orangutan orphans, who spend at least eight years learning how to fend for themselves with the help of specialists who teach lessons that would normally be taught by the orphan orangutans’ mothers. They include the very basics, like how to move and climb through the jungle, as well as crucial information such as which berries to avoid while foraging.
While there’s no “academy” for clouded leopards and the felids are more adept at avoiding human wrecking crews, they’ve suffered the same fate as orangutans when it comes to dwindling jungles.
This is the situation Sunda clouded leopards find themselves in, so when a trail camera recently captured footage of a mother and her two cubs, conservationists were thrilled.
The footage comes from camera traps belonging to the Orangutan Foundation, and it’s the first time anyone’s managed to obtain video of the Bornean clouded leopards with cubs in tow. The brief video shows the little family bounding through the jungle. They quickly move past the camera, but not before one of the cubs stops to look right at it with typical kitten curiosity.
Sunda clouded leopards are extraordinary cats. Size-wise, they are firmly in the “medium size wildcat” category, with males weighing about 50 pounds. Despite that, they are members of pantherinae, the genus of big cats, having diverged from a common ancestor shared with tigers, leopards, lions and jaguars.
As further proof of their in-between status, Sunda clouded leopards can neither purr nor roar. Typically, each species of felid can do one or the other. Even the species’ scientific nomenclature, neofelis nebulosa, references its intermediate status. (If you encounter alternate taxonomy for them, it’s because the clouded leopards of Borneo and Sumatra are considered distinct subspecies.)
“Due to a different bone structure in their neck, the clouded leopard cannot roar like the larger cats, but also cannot purr because it lacks the fully ossified hyoid bone that allows small cats this ability,” the Smithsonian National Zoo’s keepers explain.
Sunda clouded leopards have several unique adaptations that allow them to thrive in arboreal environments. Their massive tails act as crucial counterweights, allowing them to traverse branches high above the ground without falling. Their paws and paw pads are specialized for gripping tree branches, and their ankles can articulate in ways other felid ankles cannot, allowing the jungle-dwelling wildcats to descend from trees head-first.
Domestic cats infamously lack this adaptation, which is why firefighters are also part-time cat rescuers, coaxing the terrified little ones down from trees, utility poles and rooftops.

The clouded leopards of Borneo and Sumatra are also undeniably cute. People have noticed, which is why one of Google’s auto-complete suggestions for Sunda clouded leopard suggests the word “pet” as an addition. It’s okay to fantasize about having a clouded leopard buddy, but in addition to the fact that they are endangered, they’re also wild animals.
Consider the fact that across the estimated 200,000 years of our species’ existence, homo sapiens have domesticated precisely one felid species, and even that’s not entirely accurate. Felis catus played just as much of a role — and arguably more — than humans did in their own domestication. As predators and obligate carnivores, they are unique among domestic animals, and it took and equally unique set of circumstances to bring cat and man together.
Instead of lamenting the fact that Sunda clouded leopards can’t be pets, we can admire them in the best way possible, from a distance, while helping ensure the survival of this extraordinary, distinctive species by donating to groups like Panthera, the WWF and Global Conservation.
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.”

Roadside zoos persist despite recent law changes, but even the best zoos fail to provide adequate facilities and enrichment for big cats, the report found.
The Amur tigress at Bearsdley Zoo is the lone occupant of her enclosure, which is large by the zoo’s standards, outfitted with a pool, toys and other enrichment, but small compared to what her natural range would be.
When I visited last summer, I spent the better part of an hour watching her pace the perimeter of her enclosure, walking in an endless loop as if in a daze, never stopping, altering her stride or reacting to anything.
But what made me realize how bad captivity really is for big cats was what I saw at the Smithsonian National Zoo, a well-funded world class facility. The tigers there have two outdoor enclosures with a topographic design: they’re vertical spaces separated into tiers, with large trees and narrow “caves” for shelter from the elements. Both enclosures are surrounded by wide moats that ring the perimeter just inside the security fencing.

It was feeding time on a hot summer day. Lionesses chowed down on large slabs of meat and licked blocks of ice, but the lone male tiger next door was pacing in a circle. He paced and paced, covering the same 10 to 12 feet, ignoring his food. I watched him for a long time. His behavior was a clear sign of zoochosis.
If a tiger in a national accredited zoo — where an entire team of keepers and caretakers is responsible for enrichment and welfare — suffers from clear signs of captivity-induced distress, what chance do tigers in other facilities have?
When we think of big cats suffering in captivity, we think of the roadside zoos where the Joe Exotics and Doc Antles of the world exploit them for financial gain, drug them, force them to take selfies with visitors and keep them in cruel conditions. But a new report from Born Free USA goes beyond roadside zoos and says big cat arrangements, even in the best zoos, are inappropriate, unhealthy and demoralizing for the animals.
“Unable to escape the crowds of humans, unable to follow some of their fundamental urges such as hunting and roaming over large distances, unable to fulfil their social needs – whether that be living solitarily or forming a pride with others – big cats show us their mental anguish by adopting abnormal behaviors,” reads the report [PDF], Clawing at the Cages. “These behaviors, known as stereotypies, manifest in obsessive pacing. Some big cats spend most of their days tracing the same, short, tedious route around their enclosures. This behavior is a recognized sign of stress, and only documented in captive animals.”

The wild lives of animals like tigers are fundamentally at odds with the concept of zoos. In the wild, tigers range up to 50 miles in a single day, occupying vast ranges. Male tigers protect their home ranges, their mates and their cubs from other males as well as threats of all sorts.
That sort of lifestyle, which is hard-coded into their DNA, is not compatible with a guest-oriented operation in which habitats are designed primarily to give people the best view of the animals.
Lions might have it slightly better, though that’s arguable. As a social species they can interact with each other and they tend to have larger enclosures, but zoos rarely group animals according to their preferred family units or prides, instead matching individuals according to breeding plans as part of conservation efforts.
Yet even the conservation aspect is iffy, according to Born Free USA. Because of restrictions on “importing” animals and a population that is descended from just a handful of big cats, inbreeding is rampant. There’s a lack of scientific research on the captive zoo-held population, but the authors cite a 1983 study that found “six animals out of the approximately 1,000 Siberian tigers held in zoos in 1983 were responsible for 69.4% of the founder representation of the living population at that time. 70% of the population had a positive inbreeding
coefficient.”
Because little has been done to remedy that genetic bottleneck, “genetic viability remains low, and inbreeding of big cats in zoos can only have increased in the intervening years since these studies,” the report states.

Despite the passing of the Big Cat Public Safety Act, Born Free USA’s report notes, roadside zoos still exist, and many of them have simply ignored the new laws because their operators know inspectors are overworked and lack manpower. Years can elapse between inspections, even at roadside zoos operated by serial offenders with long histories of keeping animals in abysmal conditions.
For example, Single Vision of Melrose, Florida — which bills itself as a “conservation” facility — openly flaunts its mistreatment of big cats with enormously popular video content from “Safari Sammie” on Youtube, TikTok and Instagram, despite the fact that it’s been the subject of dozens of violations and has an ignominious record when it comes to the health of its big cats. The facility was charged with 20 violations of animal rights laws in the previous two years, and has had multiple cases of animals dying due to neglect, yet continues to sell “experiences” in which “guests” can interact with heavily sedated tigers, jaguars, cheetahs and other wild cats.
In her videos, “Safari Sammie” — an employee of Single Vision — is routinely seen interacting directly with the apex predators, treating them like house cats and creating dangerous situations.
Other roadside zoos and animal “experience” operators continue to intentionally inbreed big cats to create “exotic” white tigers as well as ligers, tigons and other hybrids that aren’t found in the wild but are big attractions.
Overall, the report found:
Zoos fail to provide adequate environments for big cats, including lack of space, lack of ability to hide from public view, and the regular practice of locking big cats in tiny night quarters during the hours when zoos are
closed. The latter often results in big cats spending the vast majority of their time significantly confined.
Social and behavioral needs are not met in zoos. For example, solitary big cats are often forced to live with conspecifics, and social big cats are prevented from creating natural prides. Big cats are prevented from
hunting live prey – a behavior fundamental to them – while often housed alongside prey animals who also suffer stress from being forced to live near predators.
Inbreeding of big cats has become commonplace due to limited genetic diversity among captive populations, as well as unethical and deliberate inbreeding of color morphs such as white tigers and lions,
resulting in significant health issues for the cats involved.
Due to the inbreeding of big cats in zoos, as well as their habituation to humans, big cats kept in zoos are generally not candidates for release to the wild. As such, extensive and ongoing breeding programs simply serve to ensure that zoos remain “stocked” with these animals.
Monitoring of data on big cats in captivity is incomplete, with significant numbers of individuals disappearing from studbooks – the databases ostensibly responsible for tracking living big cats in captive facilities.
The licensing system intended to implement the Animal Welfare Act in the United States only achieves superficial monitoring of big cats in zoos, due in part to its risk-based assessment protocols as well as lack of meaningful
information in reporting that would allow effective public understanding and external expert oversight.
Despite the introduction of the Big Cat Public Safety Act in the U.S. in early 2023, some facilities continue to engage in dangerous activities with big cats, both in violation of, and in compliance with the new law.
Zoos around the world have killed healthy big cats due to overcrowding and lack of perceived usefulness to breeding programs. Other healthy big cats have been killed when human error or enclosure failure allowed their escape, or when attacked by conspecifics in their enclosures.
Due to all the issues above, and others, the overall health and welfare of big cats is compromised in zoos. This results in high mortality (particularly in infants), and recognizable signs of stress in the form of significant occurrences of stereotypic behaviors.
The report includes detailed anecdotes of typical problems in captive situations involving jaguars, lions, tigers and cheetahs, documents persistent problems with habitat design and security, and outlines loopholes and other problems with existing laws, which still don’t go far enough to ensure some of the world’s most iconic apex predators aren’t exploited and forced to endure lifelong misery.

What’s with these horror movies? My human likes to curl up on the couch under a blanket, with me protectively in her lap of course, and watch these ghastly movies about serial killers, ghost infestations and lurking monsters.
Why would anyone want to scare themselves? You don’t see us creating an entire film genre dedicated to horrors like empty food bowls or late dinners, so why do humans make these movies?
Your fan, Mildly Curious in Manhattan
Dear Mildly Curious,
This is a question I’ve pondered for some time, inasmuch as I care about anything human-related to ponder. My human also watches those movies and he also does so with me sitting protectively in his lap.
Then I realized something. None of the people in these horror movies have cats!
The family from The Conjuring? They have a dog. Stanley Tucci’s family in that crappy movie about flying monsters that kill everyone? Dog! The family in that other crappy movie about giant axolotl-type things that terrorize people living in a coastal community?
You guessed it! They have a dog too.
You see where I’m going with this, right? Humans who serve us cats literally have no fear because no monster or crazy cereal killer would ever risk attacking a home with a cat in it.
Suppose a hungry evil monster is let loose in my neighborhood and is making its way through the street at night, then sees me in all my meowscular, intimidating, tigeresque glory sitting at the window, keeping watch over the nocturnal world.
That monster is going to skip right over The Buddy Domicile and go in search of easier pickings because it sure as heck doesn’t want to tangle with me and my claws. I have that effect on monsters.
They may be monsters, but they’re not stupid. Breaking into a home with a cat is like breaking into a t-rex enclosure. You’re asking to get mauled by a huge, meowscular apex predator who will eviscerate you and look handsome and badass while doing it.
People who serve us cats know this. They know no monster or killer or robber would be stupid enough to go near a house with a cat. They can probably sense my meowscularity two miles away!
So sometimes our humans may want to know what it feels like to be vulnerable, what it would be like if they didn’t have tigers like us guaranteeing that no intruder approaches. THAT is why they watch horror movies. Take it to the bank!
