The disease, transmitted by ticks and fleas, causes tumor-like growths that can interfere with eating, sometimes leading to starvation.
Wildlife officials in Colorado have warned residents to avoid approaching wild rabbits exhibiting bizarre black, tentacle-like growths caused by a fast-spreading virus.
The condition, known as cottontail papilloma virus (CRPV) or Shope papilloma virus, has been spotted in Fort Collins, where locals report seeing rabbits with quill-like protrusions around their mouths. “It looks like it was black quills or black toothpicks sticking out all around his or her mouth,” said resident Susan Mansfield.
The disease, transmitted by ticks and fleas, causes tumor-like growths that can interfere with eating, sometimes leading to starvation. Colorado Parks and Wildlife spokesperson Kara Van Hoose said infections typically occur in warmer months.
While CRPV cannot infect humans or pets, it can be severe in domestic rabbits, potentially developing into squamous cell carcinoma. Experts urge pet owners to keep rabbits indoors and away from wild counterparts.
The virus, which has no known cure, has also been reported in the Midwest. Some cases resolve naturally, but veterinarians may surgically remove growths in severe infections.
