Horned rabbits in Colorado confirmed

In Fort Collins, a group of cottontail rabbits has hornlike facial growths caused by Shope papillomavirus, a common wildlife virus.

Rabbits with virus-caused horns in Colorado

Fort Collins, Colorado, has become a focal point for a curious wildlife case. A group of cottontail rabbits has wart-like growths on their faces that resemble horns. Scientists say a common virus called Shope papillomavirus is to blame. The virus can pass between rabbits, especially in summer when fleas and ticks are more active, but it does not spread to humans or pets. The growths are usually not dangerous to the rabbits and tend to fade as the animals' immune systems fight off the virus.

Historically, the virus influenced folklore and helped scientists understand how viruses relate to cancer. It was named after Dr Richard E Shope, who identified it in the 1930s. Local wildlife officials say sightings are not unusual for the season, and authorities advise people to avoid handling wild rabbits to prevent stressing the animals.

The case sits at the crossroads of science and culture. A harmless viral condition in a small urban wildlife population can spark online chatter and colorful nicknames, which underscores the power of imagery in wildlife disease stories. Public fascination matters, but it also risks misinformation if facts are lost in the buzz. Clear, careful communication from wildlife agencies helps keep people from chasing or feeding wild animals or sharing misleading conclusions.

From a policy angle, the incident highlights the need for straightforward public information about wildlife diseases and how they behave. It also shows how local sightings can trigger broader conversations about disease ecology and monitoring. In the end, this is a reminder that science advances through careful observation, not sensational headlines.

Highlights

Ongoing monitoring will clarify how common this virus is in local rabbit populations and what it means for wildlife health.
