Virus turns CO rabbits into horned Frankenbunnies

Wildlife officials report Shope papillomavirus turning wild rabbits in Fort Collins into horned mutants, urging caution and no contact.

Virus Warps CO Rabbits into Horned Frankenbunnies

In Fort Collins, Colorado, sightings of wild cottontail rabbits show dark horn like growths around their faces. The condition is linked to Shope papillomavirus, a virus that causes raised lesions that can become black keratinised tumors. The disease is spread by mosquitoes and ticks and is not transmissible to humans. Public health officials say the images are striking but do not reflect a threat to people.

Colorado Parks and Wildlife notes there is no cure for the virus in wild rabbits. Most infected animals survive, but the tumors can interfere with eating and drinking and may lead to death by starvation. Domestic rabbits can experience more severe disease and should be treated by a veterinarian. Officials ask people not to touch affected rabbits and to contact authorities if they see a sick animal.

This case sits at the junction of science and myth. A vivid image can travel online faster than facts, turning a real wildlife disease into a horror meme. The risk is not the virus itself for people but the misperception and fear it can fuel.

Clear messaging matters. Officials should explain how the virus moves, what it means for wildlife and pets, and what actions the public should take. The jackalope link is a reminder that legends live on when people miss the science behind a spectacle. The media should avoid sensational framing that distracts from practical steps and responsible observation.
