Some cottontail rabbits in Fort Collins, Colorado, have been drawing attention because they have wart-like growths on their faces that look like horns.

Rumors spread online that rabbits infected with a virus that creates a tentacle-like growth on their faces were "invading" the U.S.

Rabbits with black, tentacle-like growths sprouting from their faces have been spotted in Colorado. Colorado Parks and Wildlife (CPW) said a viral infection called the cottontail rabbit papillomavirus caused the black growths on the rabbits.
