Bizarre Virus Transforms Rabbits into ‘Frankenstein’ Creatures with Horns and Tentacles
Table of Contents
A concerning outbreak is turning ordinary rabbits in the United States into grotesquely mutated animals, sporting horn-like growths and tentacle-like protrusions – and sightings are rapidly increasing. The unusual phenomenon, frist reported in 2024, is primarily affecting rabbits in Fort Collins, Colorado, but experts warn the virus could spread throughout the Midwest.
The Rise of the ‘Frankenstein’ Rabbits
Reports began surfacing last year when a local resident shared a photograph online depicting a rabbit’s entire head covered in black, spike-like protrusions. More recently, Susan Mansfield, a Fort Collins resident, recounted her encounter with an infected rabbit to 9News. “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 cause of thes disturbing transformations is the cottontail papilloma virus (CRPV), also known as Shope papilloma virus. This virus induces the growth of tumors on or near the animal’s head, leading to the advancement of the unsettling growths.
Public health Concerns and Safety Measures
Colorado Parks and Wildlife (CPW) has issued a stern warning to the public: do not approach or touch any rabbits exhibiting these symptoms. While CPW officials currently believe the virus is not transmissible to other species, including humans and pets, they emphasize the importance of maintaining a safe distance.
A user on Reddit posted an image in 2024 of a rabbit in Fort Collins, Colorado exhibiting signs of Shope papilloma virus.
How the Virus Spreads
The virus primarily spreads through the bites of infected mosquitoes and ticks, which transmit the DNA-altering condition to rabbits. Scientists note that direct contact between infected rabbits is a less common mode of transmission, and there have been no documented cases of insects infecting humans with the virus.
The initial sign of infection is the appearance of red, raised spots on the rabbit’s skin. These spots eventually develop into wart-like tumors, which, in many cases, evolve into keratinized papillomas – the “horns” and “tentacles” observed in affected rabbits. Though, there is a more serious potential outcome: some warts can transform into squamous cell carcinoma, a potentially fatal skin cancer if left untreated.
Impact on Infected Rabbits and Ethical Considerations
Wildlife officials state that the growths are generally harmless to rabbits unless they develop in sensitive areas like the eyes or mouth. Remarkably, some rabbits have survived for years with these growths, with locals in Fort Collins reporting repeated sightings of the same infected animals since 2024.
The situation has sparked debate online, with some questioning whether euthanizing infected rabbits would curb the spread of the virus. “Is it more humane to kill them when [they’re] like that or just leave them alone?” one person posted on Reddit. Though, animal control officials in the US have not issued any recommendations supporting euthanasia, reiterating that the virus poses no public health risk.
Protecting Pet Rabbits and Looking Ahead
For pet owners concerned about their rabbits contracting the virus, medical experts recommend prioritizing pest control, particularly mosquito prevention. If a pet rabbit becomes infected, veterinarians can surgically remove the tumors before they become malignant. While occasional spontaneous healing can occur, wild rabbits in affected areas tend to develop increasingly larger growths.
local wildlife officials continue to advise the public to observe these disfigured rabbits from a distance and avoid any interaction. The emergence of this unusual virus underscores the complex interplay between wildlife, disease vectors, and the environment, and ongoing monitoring will be crucial to understanding its long-term impact.
Did you know? – The Shope papilloma virus is named after Richard E. Shope, the virologist who first described it in the 1930s.
Pro tip: – If you live in an area with infected rabbits, consider using mosquito repellent and tick prevention measures for yourself and your pets.
Reader question: – Are there any known cases of this virus affecting other animals besides rabbits?
