Rabbits in Fort Collins develop tentacle-like growths from a virus, which is not harmful to humans.

Rabbits in Fort Collins, Colorado, are being found with tentacle-like growths on their faces, caused by the cottontail rabbit papillomavirus. These growths are not harmful to humans or dogs but can spread among rabbits. The Colorado Parks and Wildlife advises against touching or feeding the infected rabbits, which typically recover as the growths disappear during colder months.
