Fishers, which are commonly referred to as fisher cats, pose no real threat to humans. They are fairly solitary animals who avoid human contact whenever possible, living in dens and underground burrows.
Fishers are native to North America, residing from coast-to-coast in forest and semi-forest habitats ranging from Quebec and parts of Canada through Virginia. Fishers have no natural enemies other than humans, who hunt them for their fur and run over them with their cars.
Fishers eat a large array of birds and small- to medium-sized mammals. They hold the distinction as the only mammal in North America that both kills and consumes porcupines, a feat that has given rise to their reputation as a somewhat savage animal.
