Recently, people across Fort Collins and nearby areas started reporting sightings of Colorado rabbits with tentacle-like cottontails showing horn-like growths around their faces. Photos spread online quickly, sparking a mix of curiosity and fear. While these rabbits may look like creatures from a sci-fi film, science offers a straightforward explanation: a virus unique to rabbits.
In this guide, we’ll break down what’s happening, the health impacts, ties to folklore like the jackalope, and what you should do if you see Colorado rabbits with tentacles.
What Are the “Tentacles”?
The Role of Shope Papillomavirus:
- The strange, horn-like growths on Colorado rabbits with tentacles are caused by Shope papillomavirus, also called cottontail rabbit papillomavirus.
- The virus spreads through insect bites (mosquitoes, ticks, fleas) and only affects rabbits.
- Growths are made of keratin, the same protein found in human hair and nails.
- Rabbits often recover naturally, with growths falling off once their immune system clears the infection.
Impact on Rabbit Health
- In most cases, growths are harmless and temporary.
- Problems arise when they block the rabbit’s eyes or mouth, making it harder to see or eat.
- In rare cases, growths can become cancerous.
- Domestic rabbits should be checked by a vet if they show similar symptoms.
Why Are Cases Appearing Now?
Seasonal Pattern
- Reports of Colorado rabbits with tentacles usually rise in warm months, when insects are most active.
- August 2025 brought several sightings in Fort Collins, though experts note this may also be due to more public attention.
- Cooler months usually bring fewer cases as insect activity declines.
The Jackalope Connection
Folklore Roots
- The jackalope, a mythical rabbit with antlers, is part of North American folklore.
- Scientists believe sightings of rabbits infected with Shope papillomavirus inspired this legend.
- The virus itself has played an important role in science: it helped researchers in the 1930s understand links between viruses and cancer.
What Should You Do If You See One?
- Keep your distance: Do not touch or try to help wild rabbits.
Protect pets: Prevent cats or dogs from approaching affected rabbits. - Don’t panic: The virus is harmless to humans and other animals.
For domestic rabbits, consult a veterinarian if you notice similar growths.
Why It Matters?
Learning the truth behind Colorado rabbits with tentacles helps the public understand wildlife health better and avoid unnecessary fear. It also highlights how folklore, science, and modern awareness intersect in fascinating ways.
FAQs
What exactly are the “tentacles” on Colorado rabbits?
They are wart-like keratin growths caused by Shope papillomavirus. The virus is rabbit-specific and cannot spread to humans or pets.
Are Colorado rabbits with tentacles dangerous to people?
No. The virus only affects rabbits. People cannot catch it, though experts advise avoiding direct contact with wildlife.
Why are these sightings happening in Colorado now?
They’re more common in warm months when insects spread the virus. Social media has also made such cases more visible.
Do infected rabbits recover naturally?
Yes. Most rabbits recover on their own once the virus clears, though severe cases may interfere with feeding or sight.
Can domestic rabbits get these growths?
Yes, but less commonly. If a pet rabbit shows similar symptoms, a vet should evaluate it.
What should I do if I see a rabbit with tentacles?
Observe from a distance, keep pets away, and don’t interfere. Report sightings to local wildlife authorities if necessary.
How is this linked to the jackalope myth?
The unusual horn-like growths probably inspired the jackalope legend, a rabbit with antlers in American folklore.
Is there any cure or vaccine for this virus?
No cure exists for wild rabbits. Domestic cases may be managed by vets, but prevention focuses on reducing insect bites.
Are these rabbits suffering?
Most are not severely affected, though growths near the mouth or eyes can make life harder for them.
Has this virus helped science in any way?
Yes. It was one of the first viruses linked to cancer, and research on it paved the way for studying human papillomaviruses.
