Despite their common name, Fisher cats (Pekania pennanti) are not cats and do not fish. A relative of weasels, the Fisher cat’s name is most likely a mistaken derivation of the French word “fische”, which refers to the European polecat. Although Fishers won’t turn down a fish food offering, their hunting endeavors mostly focus on gray squirrels and other terrestrial goodies.
