‘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.”

Massachusetts Becomes 3rd State To Ban Declawing

The Massachusetts law is a significant victory in the quest for a national ban on the cruel procedure, which involves amputating cat toes at the first knuckle

There’s good news today from Massachusetts, which just joined New York and Maryland in banning cat declawing.

The bill, signed Friday by Massachusetts Gov. Maura Healey, prohibits all declawing surgery except for rare circumstances when it’s medically necessary, like cancer in the nail bed.

Veterinarians who violate the law face fines up to $2,500 and professional discipline if they continue the practice.

Despite its name, declawing is the partial amputation of cat toes, equivalent to cutting off human fingertips at the last knuckle.

Declawing changes a cat’s gait, causing the animal pain when it walks, and usually leads to early arthritis. It causes cats to stop using their litter boxes, because the act of standing on and shoveling litter becomes painful for them.

Last but not least, it has a profound psychological impact on felines, making them vulnerable by taking away their primary form of defense. Consequently, cats who are declawed are much more likely to bite than those with intact claws.

Most of all, declawing is cruel and inflicts a lifetime of pain on innocent animals, punishing them for doing what cats naturally do.

Aside from New York, Maryland and Massachusetts, a few dozen cities and counties have banned the procedure, ranging from places like St. Louis, Missouri, to Austin, Texas, and eight cities in California, including Los Angeles and San Francisco.

Bird Flu: Study Warns Virus Has 90% Mortality Rate In Cats, Wild Pumas Succumb To Infection, Sanctuaries On Alert

“If you feed your pet contaminated raw meat or milk, they will likely die. I’m not exaggerating, just giving it to you straight,” one infectious disease specialist warned.

In more disconcerting news from the bird flu front, a new study warns of exceptionally high mortality rates for cats who are infected with the virus.

The study found 89.6 percent of avian influenza cases in cats are fatal, making the virus a virtual death sentence.

That applies to all species of cats, from the true big cats in the panthera genus — tigers, lions, jaguars and leopards — to felines, a broad group that includes domestic cats, lynx, cheetahs, pumas, ocelots, servals, jaguarundis and others.

“We don’t know if the cats are more susceptible than anybody else,” the American Veterinary Medical Association’s Michael Bailey told USA Today. “It’s just the fact they’re exposed to higher viral burdens because of where they go.”

Whether cats are more susceptible is up for debate, but one SPCA chapter said felids of all species are “uniquely vulnerable” to avian influenza because there are so many ways it can be transmitted to them by doing nothing more than what they typically do.

Cats can be infected by catching and eating birds and mice, drinking raw milk, eating raw meat (including commercial raw pet food), and exposure to infected animals, including cows.

In Washington state, two wild pumas died after contracting the virus from prey, a development Panthera puma director Mark Elbroch called “troubling.”

“It certainly raises eyebrows and makes one wonder: is it indicative of a bigger pattern out of sight?” Elbroch asked, noting pumas are at the top of the food chain in the Pacific northwest.

To date, as many as 900 cattle herds across the US have tested positive for bird flu, according to the US Department of Agriculture, while two thirds of California’s dairy farms — 660 out of 984 — had confirmed cases as of Dec. 26.

Bird flu was the confirmed cause of death in a house cat from Washington who died after eating Northwest Naturals commercial raw food, which has since been recalled. Three house cats in Texas succumbed to the virus, which they possibly contracted from hunting mice. The bird flu was also responsible for the deaths of two domestic cats in California who drank raw milk, and 20 of 37 wild cats — including a tiger, several pumas, bobcats and a Geoffroy’s cat (pictured at left) — at the Wild Felid Advocacy Center, a sanctuary in Washington.

Veterinarians are warning people to keep their cats indoors and to avoid raw meat diets, which have become more popular in recent years. Cats should not be given cow’s milk anyway, since most are lactose intolerant. As a general rule, kittens should consume milk from their mothers or kitten-specific formula, but should not be given milk from any other source.

“If you feed your pet contaminated raw meat or milk, they will likely die. I’m not exaggerating, just giving it to you straight,” tweeted Dr. Kristen Coleman, an assistant professor at the University of Maryland’s School of Public Health.

While the west coast accounts for the majority of confirmed bird flu infections, the virus continues to spread. A map from the Centers for Disease Control shows where infections have been verified as of late December:

Unfortunately, the bird flu outbreak comes on the heels of a heavily politicized pandemic and a major loss in trust in American institutions like the CDC after efforts to obscure the origins of SARS-CoV2, the virus that causes COVID-19.

It’s not clear if the fallout will make Americans less likely to heed warnings about bird flu and other potential viruses, but animal welfare groups and virologists say people can keep their cats safe with a handful of common-sense steps.

With Bird Flu Spreading, It’s Probably A Good Idea To Keep Your Cats Inside

So far there are no cases of cats infecting humans, but a new study published Tuesday warns the virus easily mutates in infected felines.

Health officials have identified at least five cases of domestic cats infected with H5 bird flu in California, and they’re warning of multiple vectors of transmission now that both outdoor and indoor cats have been infected.

Two cats were infected after drinking raw milk from a dairy farm in Fresno, California, according to the Los Angeles Department of Public Health. That’s also how a dozen barn cats died in April after drinking raw milk from infected cows on a Texas dairy farm, the CDC said.

But three other cats who tested positive for bird flu were indoor-only, lived in the same home, and did not consume raw milk, authorities said. They’re looking into the possibility that the felines were infected through raw meat or by hunting mice.

So now it’s not only confirmed that cats are vulnerable to highly pathogenic avian influenza, or HPAI H5N1, but that they can be infected in different ways.

To be clear, it’s not a cause for panic and it doesn’t mean people should isolate from their cats, but it does mean we should be smart and considerate when it comes to protecting our pets and reducing the possibility that they can be infected.

Because millions of felines live with humans, the fear is that they can pass the virus onto us. So far there have been no confirmed cases, but a study published on Tuesday confirmed that the virus can easily mutate in cats. That means the more domestic cats are infected, the greater chance the virus mutates in a way that allows it to “bridge” to humans.

At least two people — one in Wisconsin and one in Louisiana — have tested positive for the virus and were hospitalized this week. One worked on a farm and the other may have consumed raw milk. In the meantime, health officials are monitoring the people whose three cats were infected, and they’re urging people to take precautions.

“To avoid the spread of disease, including H5 bird flu, we strongly encourage residents and their pets to avoid raw dairy and undercooked meat products, limit contact with sick or dead animals, report sick or dead birds, and keep pets or poultry away from wild animals and birds,” said Dr. Barbara Ferrer, director of the Los Angeles County Department of Public Health.

South Carolina Man Enlisted His Wife, Mother And 2 Others To Poison Colony Cats, Police Say

The felines were found deceased near open tins of tuna, and laboratory tests confirmed they’d been poisoned.

In early October, a woman who helps manage a colony of stray cats in South Carolina’s Lowcountry stopped by to feed them and was distraught by what she saw.

Six cats lay dead not far from several open tins of tuna. After the woman called for help and a larger group searched the area, they found the bodies of seven more cats and three opossums, the Berkeley County Sheriff’s Office said.

The cats were spayed/neutered and managed by volunteers from Lowcountry Trap, Neuter and Release Network, meaning their population was controlled and they were routinely monitored and given veterinary care.

Tests showed the cats were poisoned, according to the Professional Veterinary Pathology Services in Columbia and the Michigan State University Veterinary Diagnostic Laboratory.

While police were looking into the poisoning, they got a tip that a local man had been complaining about the cats and claiming they were a nuisance.

On Thursday, police charged 28-year-old Andrew Dock and 45-year-old Charles Waylon Ulmer with 13 counts of felony ill-treatment to animals with torture and one count of conspiracy. Dock’s wife, Sara Rose Dock, 23, and his mother, Laura Mary Dock, 61, were charged with conspiracy along with Michael Jeffrey Kemmerlin, 30. All five suspects live in or near Summerville, a town about 25 miles northwest of Charleston.

Each felony count is punishable by as many as five years in prison and a $5,000 fine, per South Carolina penal code.

Dock was the ringleader of the group, according to police, and enlisted the others to help him poison the cats.

“Anyone that is capable of putting out poison and creating that level of pain and suffering is a concern to me as a human in our community,” Carol Linville, founder of a local nonprofit called Pet Helpers, told Lowcountry news station WCSC. ”That is a dangerous person. If they can do it to a cat, they can do it to a dog or do anything else that they deem they don’t want around.”

Locals involved with colony management and animal rescue praised the Berkeley County Sheriff’s Office for seeing the investigation through and arresting the suspects.

“The fact that the law enforcement took this seriously and really wanted to see justice and really do their due diligence to make sure that justice is really coming for these cats. I am, I’m very grateful,” said Kayte Williams, one of the women who cared for the colony. “Hopefully nothing like this happens again because the public will know if this happens, you will be prosecuted, you will be charged and you are not going to get away with it.”

On his social media accounts, Dock describes himself as a former welding instructor at Horry-Georgetown Technical College originally from Newark, New Jersey.

All five suspects were released after posting bond, according to the Berkeley County Sheriff’s Office. It wasn’t immediately clear if they had retained lawyers, or if they were given return dates for preliminary hearings.
