Colorado Rabbits Develop Unusual Horns and Tentacles, Raising Concerns
Wild rabbits in Colorado are developing horn-like growths caused by a rabbit-specific papillomavirus, which generally does not harm the animals unless it interferes with eating or drinking. Most infected rabbits survive, and the growths often disappear over time. The virus cannot infect other species but can affect domestic rabbits, especially those housed outdoors, and people are advised to avoid touching infected animals.
