Mange

Mange is a highly contagious skin disease that affects mammals and is caused by small insects called mites.

Sarcoptic mange is the most common type of this disease affecting wildlife. In North America, sarcoptic mange has been found in red foxes, coyotes, gray wolves, red wolves, black bears, porcupines, rabbits, squirrels, and raccoons.

Animals with sarcoptic mange will often have hair thinning and loss. Severely infected animals may lose weight, act sluggish, and may lose their fear of humans.
