Rabbits with 'Horns' in Colorado Are Being Called 'Frankenstein bunnies.' Here's Why
The cottontail rabbit papilloma virus causes horn-like growths in 10% of wild rabbits, spreading via mosquito and tick bites, with no cure available, Colorado Parks and Wildlife said.
- Cottontail rabbits with horn-like growths have appeared in Fort Collins, Colorado, causing concern about their health and unusual appearance.
- The growths result from the cottontail rabbit papilloma virus, spread primarily by insect bites like mosquitoes and ticks during summer months.
- Colorado Parks and Wildlife officials state the virus creates black nodules or elongated horns mostly on the head, which may impair eating but usually do not seriously harm wild rabbits.
- Officials advise avoiding contact with infected rabbits, noting no risk to humans, but the virus can infect domestic rabbits outdoors and requires veterinary care there.
- Most wild rabbits survive the infection as growths recede in colder months, but severe cases can cause starvation if eating is hindered, highlighting monitoring importance.
