A group of rabbits in northern Colorado are sprouting growths, and it looks like something out of a horror film. The papillomavirus causes wart-like growths to protrude from the rabbits' faces, and infections often peak in the summer months during tick season.

A rapidly spreading virus is causing cottontail rabbits to grow black, tentacle-like growths out of their heads, prompting warnings to steer clear of the mutated animals.

Colorado Parks and Wildlife said the growths are caused by a virus and though unsightly pose little health risk to wild rabbits and no risk to humans.
