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.
The @SeattleTimes reported on the first 2 cases of Avian bird flu that’s killed 2 wild #cougars in Washington, as discovered by Panthera #Puma Program and Washington Department of Fish & Wildlife.

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.
