A bizarre virus is turning ordinary rabbits in the US into grotesque, horned creatures with black, tentacle-like growths sprouting from their faces – and sightings are on the rise.
The mutated rabbits have been spotted multiple times in Fort Collins, Colorado.
Reports date back to 2024, when a resident posted a photo online showing the creature's entire head covered in black, spike-like protrusions.
Resident Susan Mansfield told 9News that she recently spotted a rabbit with black spines or 'quills' around its mouth.
'It looked like black quills or black toothpicks sticking out all around its mouth,' Mansfield said. 'I thought he'd die off during the winter, but he didn't. He came back a second year – and it grew.'
The rabbits are infected by the cottontail papilloma virus (CRPV), also known as Shope papilloma virus, which causes tumors to grow on or near the animal's head.
Colorado Parks and Wildlife (CPW) has urged anyone who sees infected rabbits to stay away and not touch them.
CPW does not believe the virus can leap to other species, such as humans or pets, but is still urging the public to avoid the rabbits and not attempt to help them.
Although these 'Frankenstein' rabbits have mainly been seen in Colorado recently, researchers noted that cottontail rabbits throughout the Midwest could become infected with the rare virus.
The virus spreads mainly via mosquitoes and ticks, which bite an infected animal and pass on the DNA-altering condition.
Scientists noted that SPV rarely spreads through direct contact between these rabbits, and there are no known cases of insects infecting people with it through a bite.
The first sign that a rabbit has the virus is red, raised spots on their skin that eventually turn into wart-like tumors.
In many cases, these warts develop into keratinized papillomas, the 'horns' and 'tentacles' seen growing out of midwestern rabbits.
However, some of the warts can turn into a squamous cell carcinoma, a serious skin cancer that can be deadly if it spreads and isn't treated early.
For pet owners fearing their rabbits could contract the virus, medical experts said the best way to prevent SPV is to keep rabbits away from pests, especially mosquitoes.
If an insect bite does infect a pet rabbit with the virus, veterinarians can surgically remove the tumors before they become malignant.
