‘Swift And Lethal’: Cats Have No Defense Against Bird Flu, And It Keeps Showing Up In Their Food

Bird flu is killing cats domestic and wild, in captivity and in nature. Experts are sounding the alarm, warning people not to feed their cats raw food, allow them to drink milk, or let them roam outside where they can easily catch the virus by going after small prey.

Highly Pathogenic Avian Influenza, the clinical name for bird flu, is a danger to all animals, but for cats it’s a virtual death sentence.

Only a handful have survived infection thanks primarily to early diagnosis, intervention and round-the-clock veterinary care. In the vast majority of cases, the virus burns through its feline victims in three or four days.

Bird flu has become even more deadly for felines of late. Of the 126 domestic cats killed by H5N1 since 2022, according to the US Department of Agriculture, half of them have have died in 2025 — and it’s only been three months.

Notably, that total doesn’t include captive wild cats and big cats, such as the 20 pumas, bobcats, tigers and other felids who succumbed to the virus at the Wild Felid Advocacy Center, a sanctuary in Washington state. Nor does it include cats living in the wild, like two pumas in the same state that died in December.

To appreciate the true scope of the problem, the more illuminating statistic may be 82 million, which is the number of chickens “culled” — killed — in the US since 2022 because they were infected or raised at facilities where other birds tested positive for the virus.

Factory farming compounds the matter: more than 1.6 million egg-laying hens and 337,000 “pullets” — chickens less than a year old — were “depopulated” at a single facility in Texas last year. As staggering as those numbers are, Texas’s Department of Agriculture noted the figure merely “accounts for approximately 3.6% of the company’s total flock.”

Per the USDA:

“To provide context on the overall size of the U.S. poultry flock, there are more than 378.5 million egg-laying chickens in the United States. In 2023, more than 9.4 billion broiler chickens and 218 million turkeys were processed in the United States.”

If there ever was an example of putting too many eggs in one basket, this is it. American food supplies are vulnerable with so much concentrated in the hands of so few companies, a lesson the general public is learning the hard way now after eggs peaked at record prices last month. Things have cooled off a bit since then, but shoppers aren’t getting any benefit as grocery chains continue to charge a premium: the nationwide average for a dozen eggs was $5.90 in February, but stores in some states are still charging $10 or more.

It also raises questions about the sustainability and ethics of eating animals. Humans slaughter more than 75 billion chickens every year, and projections indicate there will be three billion more of us by the mid-2080s.

Meat from infected chickens can still end up in your cat’s bowl

Media reports about culling give the impression that those birds are removed from the food chain, but that’s not entirely true. The pet food industry has always cut corners by harvesting meat not fit for human consumption, a category that includes everything from the carcasses of sick animals, to “meat by-products” that can include beaks, hooves, eyes, hearts and other organs.

So while the culled chickens won’t show up in shrink wrap at the grocery store, they are making it into the pet food supply chain. Most pet food is “rendered,” cooked at such high temperatures that potential pathogens have been destroyed.

But an increasingly bigger slice of the market has been claimed by companies selling “premium” raw food — and that’s been the primary infection vector for domestic cats, particularly indoor cats who otherwise would have little or no exposure to the virus. (Cats who spend time outdoors can catch bird flu by preying on infected animals, just as wild cats do, and barn cats have caught it by drinking the milk of infected cattle.)

Cats are mostly lactose intolerant, and should not be given cow’s milk, despite the common misconception that it’s healthy for them.

“The animals that were depopulated could potentially have ended up in the food chain for pets,” Laura Goodman, an assistant professor at Cornell University’s Baker Institute for Animal Health, told NBC News. “It’s not uncommon for substandard meat to end up in the pet food chain.”

That’s what happened to Tim Hanson’s beloved cat, Kira, who died in February after eating raw food from a company called Wild Coast. The company has recalled the product, Boneless Free Range Chicken Recipe. It’s one of four recalls in the last month alone.

Hudson is suing Wild Coast for the veterinary bills — about $8,000 — and said he was devastated that Kira, whom he called “the happiest cat,” is gone. He said he thought he was doing right by her by feeding her the expensive raw food, but now urges people to avoid feeding their cats raw food at all costs.

“I don’t want any more cats dying,” he said. “Hopefully people can learn from Kira’s passing.”

Wordless Wednesday: Awesome Photos Of Tigers Swimming!

For tigers, going for a dip on a hot day is pure bliss.

Most cats wouldn’t go near water if even if you lured them with a giant spread of catnip and Temptations on an inflatable table.

But tigers? They love it. Here are some shots of the world’s biggest cats taking a dip.

The Cost Of Living With Tigers: People In Rural India Hide Indoors As Foresters Track 2 Hungry Big Cats

Tiger attacks are a real danger in rural India, where the big cats kill people and livestock. To protect the species, the government pulls off a difficult balancing act aimed at minimizing inter-species conflict.

In his memoir, Man-Eaters of Kumaon, legendary tiger hunter (and later staunch conservationist) Jim Corbett described how he and his men arrived to find a ghost town when they tracked a man-eating tiger to a rural village.

Every door was closed and locked, shutters were closed tight, and despite the fact that it was harvest time, not a single person was working the nearby fields.

The people who lived there had good reason to be petrified. The infamous Champawat tigress had killed more than 430 people by that point, including a young woman from the village just a few days earlier. Usually the tigress would vanish from an area after a kill, frustrating locals and hunters by popping up virtually anywhere in a 50-mile radius, but for some reason she stuck around the village and sat on the outskirts at night, keeping the local people awake with her calls.

Corbett’s famed hunt of the “demon of Champawat” happened in 1907, and although it might sound like a problem from the past, it’s current reality for people in parts of India, Nepal and, to a lesser extent, the sparsely populated mountain forests in eastern Russia.

In Garwha and Ranchi, two towns in eastern India about 215km (133 miles) apart, “villagers have stopped using forest routes to reach markets and are reluctant to leave their homes for work,” the Times of India reported on Monday.

That’s because hungry tigers have been on the prowl, demonstrating little fear of people as they help themselves to livestock. Between Jan. 1 and Jan. 6, the tigers killed and ate three cattle and a buffalo.

So far they’ve eluded camera traps, but forest rangers say they believe there are two tigers because of the distance between Garwha and Ranchi, which is almost three times the typical tiger range.

In places where big cats live in proximity to humans, especially farmers, the government pays compensation to the owners of livestock killed and eaten by the predators.

There’s also a separate, more controversial compensation program for the families of people killed by tigers. Recent court cases in the country have hinged on the cold calculations of attaching monetary value to human life, and whether families are owed compensation if their relatives knowingly entered tiger preserves.

For India, it’s part of a delicate balancing act between conserving the country’s national animal and one of nature’s most beloved species, and avoiding the ire of people who are impacted by their presence. When big cats prey on livestock, if the government does not address the situation, locals will eventually take matters into their own hands and try to kill the apex predators. That usually doesn’t work out well for either side.

On average, about 60 people are killed each year by tigers in India, according to government statistics. There’s been a sharp increase in victims in recent years, with tigers taking 110 human lives in 2022 and 83 in 2023, although it’s not yet clear why.

As for livestock, a 2018 study by wildlife biologists with the Corbett Foundation documented 8,365 reported instances of big cats killing cattle, buffalo and other animals between 2006 and 2015. That works out to about 830 per year, with tigers responsible for 570 livestock kills on average and leopards responsible for the rest.

To reduce the number of inter-species conflicts, the government of India has relocated thousands of families away from the country’s 27 tiger preserves in addition to compensating farmers for their losses.

On a tangential note, this is another reason why the persistent claims of big cats stalking the British countryside strain credulity.

To paraphrase wildlife conservationist Egil Droge of the University of Oxford, when big cats live in an area, you know it because the signs are everywhere — massive and unmistakable pug marks (paw prints) on the ground, trees left with deep gauges by males marking their territory, and dung also serving as a territorial marker.

“I’ve worked with large carnivores in Africa since 2007 and it’s obvious if big cats are around. You would regularly come across prints of their paws along roads. The rasping sound of a leopard’s roar can be heard from several kilometres,” Droge wrote in a 2023 post about alleged big cat sightings in the UK.

Last but not least, big cats eat. A lot. A reliable supply of large prey animals is necessary to support even the smallest of breeding populations, and felids of all species are known to go for easy meals — in this case livestock — when the opportunity presents itself.

Still, the idea refuses to die, and there are still regular reports from people who have seen large cats and insist they’re not our domesticated friends.

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.”

Amazing Cats: The Sunda Clouded Leopard

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.
