Public Warned to Avoid Rabbits With Horns and Tentacles
In Fort Collins, Colorado, residents have been spotting rabbits with alarming horn-like and tentacle-shaped growths emerging from their heads. These strange protrusions, described as black spines or quills, have sparked concern among the community and prompted an official warning from wildlife authorities.
Photographs and eyewitness accounts have circulated online, showing animals with what appear to be toothpick-like or quill-like extensions jutting from their faces. Colorado Parks and Wildlife (CPW) confirmed that the condition is caused by a virus.

Officials explained that the unusual appearance is due to wart-like growths triggered by Shope papilloma virus, which primarily affects rabbits. This disease has been seen in both wild and domestic populations, but recent cases in Fort Collins have drawn particular attention due to the severity of the growths.
Cases Reported in Neighborhoods
The affected rabbits have been spotted in southeast Fort Collins by numerous residents, drawing both curiosity and concern. Among those who reported sightings was Amanda Gilbert, a reporter for 9NEWS Northern Colorado, who noted the unusual appearance of the animals during her neighborhood walks.

The sightings have become a frequent topic of local discussion, with many people expressing surprise at the severity of the condition affecting these wild rabbits. One of the most widely discussed accounts came from resident Susan Mansfield, who described encountering a rabbit in her yard with black, spine-like protrusions sprouting from its mouth.
She first noticed the animal two years ago and assumed it would not survive the winter due to its alarming condition. To her surprise, the rabbit returned the following year with the growths not only intact but more pronounced, indicating that the condition can persist over long periods without necessarily being fatal.

Residents likened the growths to scabby patches that seemed to spread across the animals’ faces, making the sightings even more unsettling. These personal observations have helped authorities gather more information about the spread of the virus and its impact on the local rabbit population.
Nature of the Disease
According to Colorado Parks and Wildlife, the Shope papilloma virus is primarily transmitted through the bites of insects such as mosquitoes and ticks. Once a rabbit is infected, the virus triggers the formation of wart-like protrusions that, in severe cases, can take on the appearance of horns or tentacles. These growths vary in size and shape and may continue to develop over time, creating an alarming look that draws public attention.

While the tumors caused by the virus are often benign, there is a possibility that some can become malignant if left untreated, particularly in domestic rabbits. The growths most commonly appear on the head, ears, and eyelids, but they can also develop around the mouth. When the protrusions grow near sensitive areas, such as the eyes or nose, they can cause discomfort or interfere with basic functions like eating and vision, further affecting the rabbit’s health.
Wildlife officials emphasized that the Shope papilloma virus only affects rabbits and poses no danger to humans, dogs, or other wildlife. Despite this, they strongly advised against approaching, handling, or attempting to treat infected animals. Observing from a safe distance remains the best course of action for both the animals and the community.

Not a Threat to Public Health
Despite the unsettling appearance of the infected rabbits, experts confirmed there is no risk to public health. The main concern is for the rabbits themselves, as severe cases can hinder their ability to eat or see properly. In some situations, the growths may naturally regress, but surgical removal is often necessary for more advanced cases.
Such procedures are typically carried out by veterinarians when dealing with domestic rabbits, while wild rabbits are generally left to recover naturally unless intervention is essential. Residents in Fort Collins expressed sympathy for the infected animals. Some initially feared the rabbits might be suffering from more dangerous diseases, such as plague.

CPW clarified that these cases are unrelated to such illnesses and result solely from the virus. Wildlife officials reiterated that people should not attempt to capture or treat the rabbits, emphasizing that nature should be allowed to take its course.
Long-Term Sightings Raise Concerns
Susan Mansfield’s repeated sightings over two years highlight that some rabbits can live with the condition for extended periods. While the growths may worsen over time, not all affected rabbits die quickly. This resilience has led to further discussion among locals about the overall impact of the virus on wild rabbit populations in the region.

One unidentified resident described the appearance as “a scabby-ish-looking growth over their face” and noted that seeing the animals in this state was both sad and alarming. Photos posted on social media platforms such as Reddit have attracted widespread attention, with many commenters expressing both concern and curiosity about the unusual affliction.
Expert Advice on Prevention
Experts explained that preventing insect bites is the most effective method to reduce the risk of Shope papilloma virus in domestic rabbits. Using appropriate insect deterrents and keeping pet rabbits in secure, pest-controlled environments can help lower exposure. In the wild, however, prevention is far more challenging, especially during summer and fall when biting insects are most active.

Regular veterinary checkups are recommended for domestic rabbits to detect and treat early signs of the virus before growths become severe. While there is no cure, timely surgical removal of tumors can improve a rabbit’s quality of life and reduce the chance of complications. For wild rabbits, authorities encourage observation from a distance rather than intervention, as human handling can be harmful.
Appearance and Identification
The Shope papilloma virus is known to produce growths that can vary widely in both size and shape, creating a range of unusual appearances in infected rabbits. In Fort Collins, residents have described seeing protrusions that resemble black, spiny structures jutting from the animals’ faces. Some compared them to quills or toothpicks, while others thought they looked more like tentacles.

The dramatic visual impact of these growths has made sightings particularly memorable for those who encounter the affected animals. These abnormal growths often cluster around the mouth, making them especially noticeable when the rabbit is eating, drinking, or grooming itself.
In more advanced cases, the protrusions can spread upward to the ears and eyelids, further altering the rabbit’s facial structure and giving it an even more unusual appearance. Such changes in physical features can sometimes be mistaken for injuries or other diseases, adding to public concern. According to Colorado Parks and Wildlife, the presence of these growths does not always result in pain for the rabbit.

The main issues occur when the protrusions interfere with essential functions such as eating or vision. Despite their unusual appearance, many infected rabbits are still able to carry on with their daily activities. This explains why residents have reported seeing these animals hopping through neighborhoods in search of food, seemingly unfazed by the strange formations on their heads.
Community Reaction
While some residents expressed shock at seeing the rabbits, others voiced compassion and a desire to help. Unfortunately, handling or attempting to treat the rabbits is discouraged due to the risk of worsening their condition or spreading the virus among other rabbits.

Handling or attempting to treat the rabbits is discouraged due to the risk of worsening their condition or spreading the virus among other rabbits. This advice is consistent with wildlife management practices, which aim to minimize human interference in natural processes unless necessary.
By maintaining a safe distance, residents can help ensure that the disease is not unintentionally spread through contact. Local news outlets, including KUSA, have covered the sightings extensively, highlighting both the scientific explanation for the condition and the emotional impact on residents. Public interest in the subject has been stoked by the combination of the eerie imagery and the mystery surrounding the illness.

The Broader Impact of Shope Papilloma Virus
Although the virus is relatively common among wild rabbits, its most extreme cases tend to draw public attention. Shope papilloma virus has been documented in various regions across North America, but outbreaks in urban or suburban areas are more likely to be noticed because people encounter wildlife more frequently.
Researchers note that while the disease can persist in rabbit populations, it rarely threatens the overall survival of the species. However, in localized areas, a high concentration of cases can cause concern about the health of the population and the potential for related issues such as malnutrition if growths impair feeding.
Via ScienceDirect
The attention these cases receive can sometimes be a double-edged sword. On one hand, awareness encourages residents to follow guidelines and avoid contact with infected animals. On the other hand, it can lead to unnecessary fear or misguided attempts to intervene. Wildlife authorities stress that the best way to help is by allowing nature to run its course while continuing to report unusual sightings for monitoring purposes.

The striking appearance of the growths has understandably prompted questions and concern, but experts stress that these rabbits should be left alone to prevent unnecessary stress and the spread of the disease among rabbit populations.
Preventing insect exposure remains the best way to protect domestic rabbits from infection, while wild rabbits will continue to face the risks that come with their natural environment. For now, residents are encouraged to observe from a distance and allow nature to manage the situation, keeping both people and wildlife safe.
