Backyard Squirrels with Wart-Like Growths Explained

Several states have reported squirrels with oozing, wart-like lesions caused by squirrel fibromatosis. The condition is not contagious to humans or pets, and most infected squirrels recover within four to eight weeks. Experts advise against handling the animals and suggest removing bird feeders to reduce crowding, as outbreaks peak in spring and summer; while the disease is usually non-severe, rare cases can spread to organs, according to the Indiana Department of Natural Resources.
