Rabbits with 'horns' in Colorado are being called 'Frankenstein bunnies.' Here's why

DENVER (AP) — A group of rabbits in Colorado with grotesque, horn-like growths may seem straight out of a low-budget horror film, but scientists say there's no reason to be spooked — the furry creatures merely have a relatively common virus.

The cottontails recently spotted in Fort Collins are infected with the mostly harmless Shope papillomavirus, which causes wart-like growths that protrude from their faces like metastasizing horns.
