‘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.”

Bird Flu Kills 20 Big Cats At US Sanctuary And Prompts Pet Food Recall

Cats of all kinds are at risk of avian flu infection if they hunt birds outdoors, consume raw meat or drink unpasteurized milk.

In a tragedy that underscores how vulnerable cats of all types are to bird flu, more than half the big cats residing at a sanctuary in Washington were killed by the virus in less than a month.

Twenty cats in total died at the Wild Felid Advocacy Center, including five servals, four bobcats, two Canada lynx and a Bengal tiger.

Only 17 cats are left at the sanctuary, according to its operators.

Mark Matthews, the sanctuary director, called the H5N1 avian influenza a “wicked virus” that killed the cats in his organization’s care within 24 hours of each animal contracting it.

“We’ve never had anything like this,” Matthews said, adding that he and his staff are accustomed to cats in their care dying of old age after living long, happy lives.

In California, Gov. Gavin Newsom declared a state of emergency on Dec. 18 after infected birds were found at more than two thirds of the state’s dairy producers.

As of Dec. 26, bird flu had infected 65 Americans, the majority in California.

And the virus has now resulted in its first pet food recall, with Northwest Naturals pulling its turkey recipe “raw diet” food. A cat in Oregon died after consuming the food, according to the Oregon Agriculture Department.

As we noted in our earlier post about the variant of avian influenza, there’s no reason to panic. Even if you live on the west coast, the chances of your cats being infected are small.

But it’s probably a good idea to make sure your cats remain indoors, as health authorities warn cats can contract the virus directly by catching and eating birds. In one case, health officials believe three indoor cats may have caught the virus after killing mice in their home.

In addition, the American Veterinary Medical Association advises caretakers to avoid giving their cats milk, which they should not be drinking anyway, and raw meat. Domestic cats are generally lactose intolerant, and while cats can be infected with bird flu by eating raw poultry, they can also contract the virus by eating raw meat from other animals.
