Rabbits with black, tentacle-like growths sprouting from their faces have been spotted in Colorado Colorado Parks and Wildlife (CPW) said the black growths on the rabbits are from a viral infection caused by the cottontail rabbit papillomavirus Experts note that the growths often don't harm the rabbits,

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.

The growths are most likely caused by a summertime virus common in some U.S. states, but wildlife officials say there is no risk of transmission to humans or other animals.
