Amazing Cats: As Solitary Night Hunters Surrounded By Danger, Leopards Must Watch Their Backs

Stealthy, lethal and skilled, leopards are apex predators, but they contend with bigger cats and pack animals who pose a danger to them and their cubs.

Leopards occupy a precarious position in the hierarchy of predators.

They’re true big cats who are extraordinarily dangerous and skilled hunters, but they’re never the baddest on the block by measures of pure size or strength.

Throughout their range, which stretches from the savannas of Africa to the verdant jungles of Asia, they are forced to compete with animals who exceed them in raw physical power, or derive their advantage through strength in numbers.

In Africa leopards, known as panthera pardus in binominal nomenclature, play second fiddle to their sturdier, more intimidating cousins, panthera leo. Lions aren’t just bulkier and brawnier, they’re also unique among big cats because they live in social groups. Lions cooperate on hunts, allowing them to take down anything they come across, and the entire animal kingdom gives them a wide berth.

In Asia leopards bow to the biggest, baddest cats on the planet, panthera tigris. While lots of people mistakenly believe lions are the kings of the cat world, that distinction goes to their striped, stealthy cousins. Tigers are the heaviest, physically largest and most powerful cats, making them the apex predators on land.

It’s not just other cats who put pressure on leopards. Hyenas, wild dog packs, dangerous herd animals and colossal animals like elephants and rhinos pose a danger to the spotted big felids, if not directly then in competition for food and territory.

So for leopards to successfully thrive, they’re forced to rely on their other unique skill sets, including impressive adaptability and intelligence. They hunt when others rest, eat in places out of reach of their competitors, and know when to cut their losses.

While tigers hunt in daylight, leopards stalk their prey in the darkness. Tigers and lions have the luxury of eating out in the open, as wild dogs know it would be suicidal to lay claim to kills belonging to a pride or a tiger pushing 700 pounds. Leopards aren’t guaranteed that luxury.

Leopards aren’t just physically vulnerable to species they share a range with, they’re also at risk of going hungry. Leopards can expend their finite energy on successful hunts only to be forced to abandon their kills to lion prides and canine packs. They can mitigate the risk by dragging their kills up into trees using their powerful limbs and sure footedness, or taking them into the tangle of the underbrush, though neither method is fool-proof.

Perhaps that’s one reason why, despite being the smallest and lightest of the big cats, leopards have a reputation for being particularly ferocious.

The Champawat tigress, also known as the Demon of Champawat, is history’s most notorious man-eater, but the lesser-known Panar Leopard was equally deadly, with more than 400 confirmed kills. The Leopard of Rudraprayag, contemporary with both, had a shorter reign of terror but took 125 human lives.

All three were killed by the legendary hunter Jim Corbett, whose name was synonymous with taking out man-eaters for decades before he became a big cat conservationist later in life. In his book Man-Eaters of Kumaon, Corbett described leopards as the trickiest big cats to track, and hunting them — as opposed to the canned kills favored by modern “sportsmen” — presents significant physical danger and risk of death even to experienced hunters.

Considering the level of self-awareness, understanding and deceptiveness displayed by animals like the Champawat tigress, who changed her tactics several times as Corbett tried to close in on her and nearly killed him by setting up a clever ambush, for Corbett to attribute even greater wiles to leopards speaks to their extraordinary ability to adapt on the fly and anticipate what their enemy might do.

When it comes to hunting man, there are two things that distinguish leopards from their tiger and lion counterparts. (And if you’re wondering where jaguars fall on the list, they don’t. There are no recorded cases of prolific man-eating jaguars, a fact often attributed to the animals’ tightly controlled abilities and reputation for calmly assessing situations. Jaguars very rarely kill humans, and when they do it’s because people have threatened them or their cubs, leaving them no chance to withdraw safely.)

As disruptive as man-eating tigers are, people living in areas stalked by them can find refuge indoors. Tigers hunt by day and won’t enter human-built structures, but leopards have no such limitations.

Both the Panar and Rudraprayag leopards, as well as other man-eaters of their species, were known to barrel through doors or leap through windows at all hours to catch sleeping humans unaware and drag them screaming into the night. It’s pure nightmare fuel and has a profound psychological effect. When man-eating leopards terrorize an area, there’s no true sanctuary.

While lions and tigers become man-eaters due to injuries — broken teeth most commonly — and old age, leopards do so because of opportunity and convenience.

For example, the man-eating leopards who terrorized India in the late 1910s and early 1920s acquired a taste for human flesh because the Spanish flu ripped through regions where they range. Survivors were hesitant to handle their bodies to bury them, and leopards found easy meals. From there, experts believe the big cats realized hunting humans is often easier than hunting agile ungulates and other typical prey — at least in the short term, before humans organize and retaliate.

Leopards are often confused with at least two other cat species, jaguars and pumas. It may be somewhat difficult to tell leopards and jaguars apart in a zoo without the benefit of signage, but in the wild they don’t co-exist. Anyone who encounters a spotted cat in the wild in Africa or Asia is looking at a leopard, while jaguars are native to the Americas, ranging across most of South America and the southern US.

Otherwise, there are visual differences. Jaguars are bulkier and more muscular, with shorter limbs, and their rosettes or “spots” have small flecks inside them. Leopards have longer limbs and may have broken rosettes, but generally do not have the small flecks and dots within their rosettes.

As for pumas, they look nothing like panthera pardus or panthera onca (jaguars), and they are not true big cats, lacking the ability to roar and boasting a different lineage. But because pumas, jaguars and leopards are all colloquially called “panthers,” some people confuse them.

Both leopards and jaguars have melanistic (black) variants, but their coats are not entirely black. Under the right lighting conditions their rosettes are visible, making it possible to differentiate them visually. There are legends of melanistic pumas, but no one’s been able to verify them.

As opportunistic hunters, a leopard’s lunch or dinner is whatever it can reasonably catch, and along with pumas they’re generalists and will eat just about anything despite their individual preferences.

They’re masterfully stealthy and can ambush prey in a multitude of ways, including from above thanks to their excellent climbing abilities. Leopards are exceptionally strong despite their relatively small size compared to other big cats, and they’re able to drag carcasses larger and heavier than themselves up trees. They can descend from trees head-first, giving them an enormous advantage when attacking from elevation.

Sadly, leopards numbers are in decline across the world. Habitat fragmentation plays a major part, as does poaching to feed the insatiable Chinese traditional “medicine” market for big cat parts, which are used in tonics and folk recipes. They’re also hunted by nomadic tribes in Africa for their skins.

Then there’s the cruelty of nature itself. As adaptable and successful as adult leopards are, getting to that point involves trial and error, lots of learning and luck. By some estimates fewer than half of leopard cubs reach adulthood, with the others succumbing to other predators, poachers and illegal wildlife traders who sell the cubs to people who buy them as status symbol pets.

Tigers Make A Triumphant Return To Russia’s Far East, Bringing Hope To The Species’ Future

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.”

Disabled Young Mountain Lion Gets A New Home

Nicholas requires regular veterinary care after his mother was killed and he almost lost his life when a driver struck them on a California highway.

Nicholas was just a cub and was following his mother across a busy toll road in Orange County, Calif., in 2020 when a driver hit them, killing his mother and leaving him with life-long disabilities.

Along with the trauma of watching his mother die, the little puma endured months of surgeries to repair his body. Since then, young Nicholas had been living in a sanctuary in northern California, but was about to find himself homeless when the sanctuary’s operators went bankrupt.

With just hours to go before that facility was closed, a sanctuary called Lions, Tigers & Bears of San Diego County swooped in and agreed to take the special-needs puma, who requires regular veterinary care.

“Nicholas has a head tilt and neurological issues, both conditions require ongoing veterinary care,” Lions Tigers & Bears founder Bobbi Brink told KTLA. “We’ve had a few animals with these issues, so our veterinary team is well-versed in providing the specialized care required for Nicholas, and we’re relieved to give him a permanent home with a den, a healthy diet, medical care and enrichment and toys.”

The handsome young puma is currently in quarantine, Brink said, and will be moved into his permanent habitat after 30 days.

Although California is part of their native range and home to a relatively stable population of mountain lions, the species is seriously threatened by habitat destruction, habitat fracturing and vehicle traffic. Some 70 pumas are killed each year on California’s highways, and experts say the survivors are stranded on isolated “islands” of habitat, separated from potential mates by deadly highways. Indeed, scientists who track native wildlife in California have noted signs of inbreeding among pumas, as the animals are cut off from other populations of their species.

The life of the much-celebrated, recently deceased mountain lion P-22 illustrates the problems faced by the unique cats.

P-22 became famous when he migrated from southern California to Los Angeles, crossing the state’s busiest and most dangerous highways to get there. He settled in LA’s Griffith Park, which straddles the hills with the famous Hollywood sign and the outdoor Greek Theatre.

Although he became a local icon, frequently making cameos on the doorbell camera systems of people living nearby and making his rounds through the park and surrounding neighborhoods, P-22’s range was only nine square miles — the smallest range ever recorded for an adult male mountain lion — and he did not have opportunities to mate and produce cubs, as his kingdom was cut off from areas where he might encounter female pumas.

One solution to the problem is to build land bridges connecting areas where mountain lions and other wildlife make their homes. In April of 2022, officials broke ground on the Wallis Annenberg Wildlife Crossing, which when complete will connect Agoura Hills to the nearby Santa Monica Mountains.

But such projects are wildly expensive and take years to complete. The Wallis Annenberg Wildlife Crossing has a $90 million price tag and won’t be finished until 2025. On the bright side, about two thirds of the cost has been covered by private donations, proving Californians and other wildlife lovers are invested in the survival of mountain lions, coyotes, deer and other fauna expected to make use of the bridge.

It’s also an encouraging sign indicating efforts to educate the public about local wildlife have been successful. Along with the other problems they face, pumas — also known as catamounts, cougars and dozens of other names — are often confused with African lions.

Because they’re large cats, they’re called lions and they resemble their African counterparts, many people assume mountain lions are dangerous. But not only are mountain lions (puma concolor) an entirely different species than African lions (panthera leo), they are not in the same category of felid.

Pumas are actually felines, meaning they’re more closely related to domestic cats, and like smaller cats they can purr but cannot roar. True big cats, like tigers, lions, jaguars and leopards, are members of the genus panthera and are capable of roaring, but not purring or meowing.

Perhaps most importantly, pumas are not aggressive toward humans. There are only 27 recorded deaths from encounters with mountain lions over the past century compared to more than 50,000 deaths from dogs, for example, and in almost every one of those cases the pumas were either cornered or their cubs were threatened.

Nicholas is not only a reminder that animal life is valuable, his circumstances also remind us that we’re going to have to find creative ways to ensure the survival of many species as humanity expands. The global population is expected to level off at about 11 billion and then slowly contract as third-world countries undergo the same lifestyle changes common to nations that have already made the transition to first world. But until then, it will take a massive and coordinated effort to ensure we don’t end up on a very lonely planet and likely endanger our own survival with the cascade failures that arise from extirpating entire species.

Why Are UK Cat Owners So Intent On Allowing Their Cats To Run Free?

A UK couple created a cat flap that uses algorithmic AI to determine if their cat is trying to come inside while carrying prey in her mouth. If she’s carrying prey, the cat flap won’t open.

Jinx the cat was so grateful to UK couple Martin Rosinski and Michelle Bowyer for giving her a home that she decided to bring them a gift.

“The first time I was working at home, I heard Michelle making a commotion because Jinx had come in with a mouse and dumped it on the carpet in front of her as a ‘thank you’. That’s their way of expressing love. You can’t tell her off, so we thanked her a lot for it and took it away from her,” Rosinski said.

“Then this started happening more and more often to the point where we would be woken up at 2 a.m. as Jinx would meow loudly and announce, ‘Hey I have a gift. If we didn’t get to her fast enough she would decide to eat it herself, which would involve piles of mouse parts being smeared into the carpet. This was happening at 2 a.m., then again at 4 a.m. on many nights and we’d not get any sleep having to deal with this. Her record was four in one night – that night was a frenzy of three mice and one bird. It was something that was a real cause of stress.”

The solution is pretty simple, right? Keep Jinx inside.

The former stray won’t like it at first. There will be an adjustment period when the meowing will be seriously annoying. But it’s better than allowing your cat to play Predator at night and waking up to find your cat sitting on your chest, proudly presenting a twitching mouse to you.

Rosinski and Bowyer didn’t take Jinx inside.

Instead they created a bespoke intelligent cat flap that allows Jinx to come and go as she pleases, but won’t open if she’s carrying prey. They both have backgrounds in tech: he’s a researcher who also tinkers with software and hardware, and she’s a web developer.

Their system, OnlyCat, uses a camera and an algorithm to determine if Jinx is carrying something in her mouth. If she is, the cat flap won’t grant her access, and Bowyer and Rosinski will get a text informing them Jinx has been up to her hi-jinx again, along with a photo of her entry attempt.

The OnlyCat prototype has prevented Jinx from bringing in 42 prey animals since June of 2021, the couple said. OnlyCat may prevent her from bringing her prey inside, but it hasn’t dissuaded her from killing.

“Two months ago I think something clicked and she realized, ‘I can’t bring these home. It’s just not going to work,’” Rosinski told the UK’s South West News Service. “She still catches them outside but she’s learned that there’s no point even trying to bring them home, which is a relief.”

The couple developed the OnlyCat into a full product, which launches on Aug. 16 at £499. (A little more than $600 USD.) Their site says the retail version of the flap has worked 100 percent of the time in tests, and the developers believe “99%+ accuracy should be achievable for everyone.”

It’s similar to a device built by Amazon engineer Ben Hamm which uses DeepLens, an AI-enabled camera system, and Sagemaker, a software tool for training machine-learning algorithms, to determine if cats are carrying prey.

Hamm’s version, which he created for his cat Metric in 2019, initiates a 15-minute lockout timer if Metric tries to enter while carrying a kill, and automatically sends a donation to the National Audubon Society, which protects birds and their habitats. The algorithm was trained using tens of thousands of images of cats approaching normally, and with prey in their mouths. So far, Hamm hasn’t developed a retail version of his AI-enabled cat flap.

We don’t think there’s any one way to raise cats, and it’s obvious there are different cat cultures in various countries.

Nevertheless, seven out of 10 cat owners in the UK allow their cats to roam free, and anecdotes like the ones about Jinx, with her multiple kills a night habit, draw the ire of birders and conservationists.

Peter Marra is the author of Cat Wars: The Devastating Consequences Of A Cuddly Killer and co-author of many of the leading studies claiming cats are the primary threat to bird populations. He’s currently making the media rounds and endorsing strict policies — many of them in enacted in response to his studies — that would make it illegal to allow cats outdoors.

The Australian government is airdropping poisoned sausages by the ton in a plan to cull as many as two million cats, a town in Germany tried to ban outdoor cats, a US politician recently suggested starting a “hunting season” for feral and stray felines, and some people — including wildlife biologists and conservationists — have gone vigilante and convinced themselves they’re doing good by randomly picking off cats with shotguns and poisoning feeding stations for strays.

Maybe it’s time for more people to reconsider allowing their cats to roam free. Like putting a cat on a diet or trying to break a bad habit, there’ll be loud and annoying protests in meow, and it’ll get worse before it gets better, but eventually cats always adjust to changes if given long enough.

As domesticated animals they don’t have a natural habitat anymore, and they don’t actually need to be outside. It’s entirely possible to keep things fun and interesting for the furry little guys, and that’s on us. All that’s required is our time, attention and affection. Interactive play time. Toys that can keep a cat occupied by herself. Catnip. Condos and tunnels. Window perches. Cat TV on Youtube. Simple things to play with, like plastic bottle rings, crinkled tin foil and cardboard boxes.

We don’t think anyone should be required to keep their cats indoors, and that’s the point. We have an opportunity to meet conservationists halfway and make a real effort to reduce feline impact on small wildlife. If we don’t, eventually we’ll be forced to comply by laws that’ll be draconian compared to the voluntary measures we could have taken to prevent the government from getting involved.

Letting Your Cat Outside Could Cost You $50k In This German Town

Town officials say the step is necessary to protect a ground-nesting songbird native to western Europe.

Elected leaders in Walldorf, Germany, are worried about the crested lark — so much so that they’ve decreed cats must be kept inside, with prohibitively painful fines for anyone whose cat harms one of the birds.

According to the decree, anyone who allows their cat(s) to roam outside from now until August will be fined €500, which is about $527. But if a cat kills or injures one of the European songbirds, Walldorf’s local government will fine the cat’s caretaker up to €50,000, almost $53,000 in USD.

That’s an eye-watering amount of money, especially in light of the fact that the crested lark is listed as a species of “least concern” by the International Union for Conservation of Nature. Experts say humans, not cats, are the biggest threat to the bird.

Officials in Walldorf — a town of about 15,000 people more than 600 kilometers southwest of Berlin — cited the same thoroughly-debunked studies that claim cats kill some 25 billion birds and small mammals annually in the US alone. They say they’re worried because the crested lark nests on the ground, making the birds, their eggs and their chicks particularly vulnerable to predators like domestic cats.

If you’re skeptical that local government officials — a mayor and town councilmen, essentially — are qualified to legislate on matters of conservation, you’re not alone. The decree has been met with pushback from animal rights advocates and feline fans.

“Suddenly preventing cats that are used to going outside from doing so, means immense restrictions and stress for the animals,” German animal welfare group Deutscher Tierschutzbund wrote in a statement. “The negative influence of cats on the population of songbirds is in any case controversial and, to our knowledge, has not yet been proven for the crested lark in Walldorf.”

And that cuts to the heart of the matter, doesn’t it? Like politicians in Australia and parts of the US, Walldorf’s elected leaders aren’t making decisions based on studies or reliable information. They’re taking action based on emotion and deeply flawed meta-analyses that aren’t even applicable to Europe.

We’ve always taken the position here at PITB that cats are much better off indoors. They’re domesticated animals, meaning if they have a “natural habitat” it’s human living rooms. They live much longer, healthier lives indoors and can be happy and fulfilled with a little effort on the part of their humans.

But we also believe decisions impacting living creatures should be based on real information gathered by people who don’t have an agenda. The landmark Washington, D.C. Cat Count is a great example, with birders, conservationists and cat lovers working together to complete an accurate census of domestic felines within city limits.

Now that they’ve established how many cats live in D.C. (about 200,000) and how many are truly feral without anyone caring for them (about 3,000), they can enact sensible solutions that are much more likely to successfully protect wildlife and cats without hysteria, agendas or inhuman proposals like enacting “cat hunting season” (as one US politician proposed), killing millions of cats with poisoned sausages (as Australia has done), or outright gunning cats down, as a rogue conservationist in California’s Bay Area did last year.

Cats are thinking, feeling animals. They deserve better than becoming the victims of human policies based on ignorance.
