In Colorado, a viral infection has caused rabbits to develop unusual tentacle- or horn-like growths on their heads, alarming local residents. The Colorado Department of Parks and Wildlife confirmed that the condition is caused by the cottontail rabbit papillomavirus, which leads to wart-like or tentacle-like growths. This virus affects only this species and is not contagious to other animals or humans. Despite their grotesque appearance, scientists emphasize that the infected rabbits are not dangerous. The phenomenon has drawn widespread attention and comparisons to mythical creatures such as the jackalope. Meanwhile, reports have also emerged of squirrels in the United States exhibiting wart-like tumors, described as 'zombie squirrels,' which are believed to carry a different virus. The World Health Organization has issued a global warning about the reemergence of a previously feared disease, though it is not specified whether this relates directly to the rabbit or squirrel infections.
