A wild epidemic threatens local wildlife as ‘Frankenstein rabbits’ with grotesque tentacles prompt warnings from authorities. Rising Concerns in Fort Collins In recent months, residents of Fort Collins, Colorado, have reported sightings of wild rabbits with disturbing tentacle-like growths on their heads. These growths are attributed to the Shope papillomavirus (SPV), a virus known to cause keratinized papillomas in rabbits. Colorado Parks and Wildlife (CPW) has issued advisories urging the public not to touch these animals, citing low risk to humans but emphasizing the importance of avoiding contact.

This phenomenon is not entirely new; similar cases were documented in Minnesota back in 2013, where viral videos of rabbits with horn-like growths circulated online. These incidents have now resurfaced in Fort Collins, drawing national media attention and reinforcing public caution. Understanding the Virus Shope papillomavirus is transmitted primarily through insect vectors like mosquitoes and ticks. While the virus results in striking physical deformities in rabbits, wildlife experts assure that it poses little threat to humans or domestic animals. The CPW continues to monitor the situation, emphasizing that while the growths are unsightly, they typically do not harm the rabbits unless they interfere with vision or feeding. Reports indicate that the phenomenon is a recurring wildlife issue rather than a sudden outbreak. The CPW has not recommended euthanasia for affected rabbits, advising instead to let nature take its course. This guidance helps prevent unnecessary interventions that could disrupt local ecosystems. Public Response and Safety Measures As images of these rabbits spread across social media, the public’s reaction has varied from curiosity to concern. CPW has reiterated its stance that residents should avoid handling the animals. The department encourages reporting any unusual wildlife behavior to authorities.
