Colorado Rabbits with 'Horns' Earn 'Frankenstein Bunny' Nickname

A group of rabbits in Colorado with hornlike growths are infected with the harmless Shope papillomavirus, which causes wart-like protrusions. These 'Frankenstein bunnies' have inspired nicknames and are linked to historical folklore and scientific research, but the virus poses no threat to humans or pets and typically resolves on its own.
