a fisher cat is a member of the marten family. It's an omivor - which means like a bear or wolverine it can eat a variety of things. It's a fairly secretive animal, which can also be fairly aggressive. it moves around in the dusk, dawn and night. It's the scourage of chickens, and small pets. It has very sharp claws/talons - non retractable, and can move quickly. It's also very strong. About the size of a raccoon. Leave it alone. and make sure that your livestock quarters are tight. they were reintroduced back into the new england area - one of it's orginal regions. Thankfully, we've never laid eyes on one here, but they are around - kind of like coyotes - all around you but you'd never know.
