Unusual Rabbit Growths in Fort Collins, Colorado: Understanding a Viral Condition

Residents across Fort Collins, Colorado, have recently observed a striking sight: rabbits exhibiting peculiar, horn- or tentacle-like growths on their heads and faces. While these appearances can be visually alarming, wildlife officials have confirmed that this condition is caused by a virus and poses no threat to humans or other animals. This comprehensive article delves into the nature of this virus, its specific effects on local rabbits, and provides essential guidance for residents who encounter affected animals in Colorado.

Understanding Rabbit Papillomavirus: The Cause of Unusual Rabbit Growths

The distinctive growths appearing on rabbits in Fort Collins are attributed to a specific viral condition: rabbit papillomavirus, commonly known as Shope papillomavirus. Colorado Parks and Wildlife (CPW) has officially identified this virus as the origin of these unusual rabbit growths, a condition that has been present in the region for several years. These benign rabbit tumors often manifest as wart-like projections, sometimes described as resembling black spines, scabby outgrowths, or even small “toothpicks.”

Is Rabbit Papillomavirus Contagious to Humans or Pets?

Colorado Parks and Wildlife provides crucial reassurance: the Shope papillomavirus is not contagious to other animal species, including domestic pets, nor is it transmissible to humans. This important fact should alleviate any concerns about wider outbreaks or health risks to household animals. Despite the visually unsettling nature of these rabbit growths, the virus typically poses no significant threat to the affected rabbits themselves.

Impact of Papillomavirus Growths on Rabbits & Available Treatment

While these rabbit papilloma growths are generally benign, they can become problematic if their size or location interferes with crucial functions like eating, drinking, or seeing. Encouragingly, there have been reports of rabbits successfully surviving an entire winter with these unusual growths, suggesting the condition doesn't always lead to mortality. It's important to note that, currently, there is no known cure for the Shope papillomavirus. The growths resemble benign cancerous cells and will continue to grow without direct intervention.

Encountering Rabbits with Growths in Fort Collins: What to Do

Wildlife authorities strongly advise residents in Fort Collins, Colorado to avoid approaching or touching any rabbits exhibiting these viral growths. While the rabbit papillomavirus is not harmful to humans, disturbing these wild animals can cause them significant stress. The most responsible action is to leave the affected rabbits undisturbed, allowing them to cope with the condition naturally in their environment.
