There are increasing reports of the cute furry little squirrels of North American backyards being replaced with tumor-ridden rodents that appear painfully disfigured.
These trends first started in 2023 when numerous home owners in the U.S. and Canada posted pictures of the cringeworthy sightings on social media.
According to experts in the field, when one of these furry friends has the condition, it is likely to spread—especially in cases where people feed them.

One such person posted an image of an eastern grey squirrel with the side of its face disfigured by hairless growths and captioned it “What’s this?”
“Can grey squirrels survive squirrel pox?” asked another. “I see a few with early symptoms in my backyard.”
One Redditor posted a particularly severe case of the ailment occurring over most of a squirrel’s body and wrote, “Squirrel Pox, ladies and gentlemen,” and then “thank God they’re only for squirrels.”

Experts have since confirmed that the condition is in fact the so-called “squirrel pox,” or as it is called in scientific circles, squirrel fibroma.
Experts appear split on the primary cause of the unsightly condition
The Wisconsin Department of Natural Resources notes that the ailment is “characterized by varying sizes and numbers of wart-like growths or fibromas on the skin of squirrels.”

It goes on to say that the juveniles of the species tend to be susceptible to it.
“Biting insects, such as mosquitos, are likely the primary route of transmission between squirrels,” the government outlet observed.
It advises that the best way to mitigate the spread of the virus is by eliminating sources of standing water where mosquito vectors breed.”

Wildlife biologist Shevenell Webb, from Maine, tells a different story.
While agreeing that the ailment is “naturally occurring,” she blames its spread on people when, usually with good intentions, they provide food for the creatures in bird feeders.
“It’s like when you get a large concentration of people,” Webb explained. “If someone is sick and it’s something that spreads easily, others are going to catch it,” per Bangor Times.

In the case of the squirrels, the virus is spread through saliva as it lands on the food or rubs off on the feeder itself.
There are times when the ailment proves fatal, but this is rare
“It’s nothing to really worry about,” Webb assures. “For the most part, squirrels with squirrel pox are just really ugly to look at.”
She says the ailment usually tends to run its course and heal completely. It is not often that it proves fatal, and when it does, it is because growths form in locations that hamper the creature’s ability to eat, move, or see.

When this happens, they will likely starve or fall prey to animals.
Fortunately for pet owners, the illness is species-specific
North Carolina Wildlife Resources Commission notes: “Humans, cats, and dogs cannot contract squirrel fibroma virus. Although uncommon, it is possible for domestic or pet rabbits to contract the disease.”
There are exceptions, but they are rare.

“The virus can also be transmitted to groundhogs and rabbits, although contraction of the virus is uncommon in these animals,” the state organization writes.
Testimonies from wildlife enthusiasts give weight to experts about the disease being survivable

As a testimony to the experts' claims that the animals are prone to survive the condition, one Redditor posted a video of an active and sprightly looking member of the squirrel family and wrote:
“He beat the worst squirrel pox I have seen and is recovering well.
“Bad scars but almost full function again and is socializing a little too!
The internet thinks squirrel pox is symptomatic of a serious problem somewhere
