Recent sightings of rabbits with tentacles protruding from their heads have alarmed Fort Collins residents, with Colorado Parks and Wildlife confirming the cause is a viral infection. The condition manifests as black, tentacle-like protrusions coming from infected rabbits’ heads, creating an unsettling appearance that has captured widespread attention.
Southeast Fort Collins residents began noticing these unusual-looking animals in recent weeks, including 9NEWS Northern Colorado reporter Amanda Gilbert who documented the phenomenon. The distinctive growths have prompted multiple wildlife agencies to issue public warnings about approaching these infected animals.

What Causes These Disturbing Growths?
The bizarre appearance results from cottontail papilloma virus (CRPV), which causes benign tumors to materialize on rabbits’ heads. This infection is caused by a cousin of the human papillomavirus, though it poses no threat to people or pets.
The Shope papilloma virus belongs to the DNA virus family and is a member of the papovavirus group, with transmission occurring through biting arthropod vectors. While rare in laboratory settings, this disease appears most frequently in cottontail rabbits of the Midwest, occasionally affecting domestic rabbit populations.
Expert Warnings and Safety Measures
Wildlife officials emphasize that despite the alarming visual impact, these infected rabbits pose no danger to humans or pets. However, authorities strongly urge residents to maintain distance from affected animals.
Colorado Parks and Wildlife officials stress that people should avoid approaching or touching the infected rabbits, even though the virus cannot transmit to dogs or humans. This precautionary measure helps prevent stress to the animals and reduces any potential complications.
Historical Context and Scientific Significance
This viral condition has historically contributed to the “jackalope” myth, where rabbits appear to have antlers growing from their heads. The current outbreak demonstrates how folklore often stems from real biological phenomena that early observers couldn’t fully explain.
Cottontail rabbit papillomavirus holds significant scientific importance as the first papillomavirus associated with tumor development, serving as a research model for over 90 years. Scientists have extensively studied this virus to understand papillomavirus pathogenesis and develop treatment strategies.
Current Outbreak Status
Reports of these mutated rabbits date back to 2024, with recent sightings indicating an uptick in cases throughout Fort Collins. Local wildlife photographers and residents continue documenting these striking examples of viral infection in wild populations.
The affected animals display various growth patterns, with some developing multiple projections while others show single prominent growths. These wart-like projections emerge primarily from facial areas, creating appearances that wouldn’t look out of place in horror movies.
What Residents Should Know
Public health officials want residents to understand several key points about this situation:
- The virus affects only rabbits and cannot spread to humans or domestic animals
- Infected rabbits typically survive with these growths, though they may face feeding challenges
- The condition represents a natural occurrence rather than environmental contamination
- Professional wildlife management handles monitoring and intervention when necessary
Looking Forward
Wildlife biologists continue monitoring the outbreak’s progression while educating the public about this fascinating yet unsettling natural phenomenon. These benign tumors, while visually disturbing, represent normal viral activity within rabbit populations.
The Fort Collins situation serves as an important reminder of nature’s complexity and the various viral conditions that affect wildlife populations. As research continues, scientists gain valuable insights into papillomavirus behavior that may benefit both animal and human health understanding.
Stay informed about local wildlife developments and remember to observe these unique rabbits with tentacles from a respectful distance, allowing nature to take its course while keeping both animals and humans safe.
