Colorado rabbits grow hornlike growths from a common virus

Viral photos of hornlike growths on Colorado rabbits draw attention while scientists say the condition is a common, harmless infection.

Colorado rabbits grow hornlike growths from a common virus

A group of wild rabbits in Fort Collins, Colorado, are infected with Shope papillomavirus, a virus that causes wartlike growths on the face and can resemble horns when they grow longer. The growths are a familiar sight in wild cottontails and are not a threat to people or domestic animals. The virus spreads between rabbits through fleas and ticks and does not jump species.

Wild rabbits often recover as their immune system fights the virus, and the horns disappear over time. Domestic rabbits can experience more severe symptoms and should be checked by a veterinarian. Colorado Parks and Wildlife notes that cases are more common in summer when vectors are most active. The virus was named after Dr. Richard E Shope, who identified it in the 1930s, linking wildlife disease to early virology and cancer research.

The story blends a scientific fact with a bite of folklore. Striking photos can make people imagine jackalope myths, yet the science behind the condition is straightforward and not dangerous to humans. Clear information from authorities helps keep curiosity online without turning into fear.

This is a chance to highlight wildlife health and the value of surveillance. Officials should communicate how the virus spreads among rabbits and why it does not threaten broader health. Covered well, the tale becomes a reminder that science can explain odd wildlife appearances without inflating risk.
