A group of rabbits in Colorado, displaying unusual horn-like growths, has caught the attention of locals and sparked fascination akin to scenes from a low-budget horror film. However, scientists clarify that the rabbits are infected with a benign virus known as Shope papillomavirus, which can lead to wart-like formations. These grotesque protrusions have led to unflattering nicknames such as “Frankenstein bunnies,” “demon rabbits,” and “zombie rabbits.”
The recent sightings in Fort Collins have been met with curiosity, but experts note that the Shope virus is not new; it has been present in rabbit populations for nearly a century and has historical ties to folklore, possibly inspiring the jackalope myth—a legendary creature depicted as a rabbit with antlers.
Named after Dr. Richard E. Shope, who first identified the virus in cottontails in the 1930s while conducting research, the virus has contributed to advancements in the understanding of the correlation between viruses and certain cancers, including the human papillomavirus linked to cervical cancer.
As reports of the peculiar rabbits spread, the Colorado Parks and Wildlife department has received numerous calls from concerned residents. A spokesperson explained that instances of infected rabbits, particularly during summer when parasites such as fleas and ticks are prevalent, are fairly common. The virus is contagious among rabbits but poses no risk to humans or pets.
Although the growths may appear alarming, they are typically harmless unless they affect the rabbits’ vision or ability to eat. Most rabbits can effectively combat the virus, leading to the eventual disappearance of the growths once their immune systems respond appropriately.
In summary, while these unusual rabbits may appear fearsome at first glance, they are simply victims of a common virus, and their condition does not pose a threat to other species.
