Colorado residents have reported sightings of rabbits with horn-like growths caused by the Shope papillomavirus. While the virus creates unsettling appearances, causing nicknames like "Frankenstein bunnies," it's generally harmless to the rabbits and poses no threat to humans or pets. The virus, discovered in the 1930s, is more common in summer when fleas and ticks are active. Although the growths can look alarming, they usually disappear once the rabbit's immune system overcomes the infection. The virus is related to human papillomavirus (HPV), highlighting its scientific significance.
