After ‘Frankenstein’ rabbits, ‘zombie squirrels’ are haunting Americans

Across the U.S. and Canada, squirrels are appearing with grotesque tumors due to squirrel fibromatosis, a viral skin disease spread through direct contact. While alarming, experts assure it’s harmless to humans, pets, and birds, typically resolving in weeks. Simultaneously, Colorado rabbits are developing antler-like growths from Shope papilloma virus, transmitted by parasites, also posing no threat to other species.
