We have Fishers, AKA fisher cats, here in the Catskills of NY. I saw one cross the road right in front of my truck, about 300 yds from my house this past summer.
The town my wife is from, Pinehill, has had one, or a few that were coming into town and killing peoples cats. My mother in law has lost a few cats to them. The most recent one about 3 months ago. Also one night one of my wifes best friends had what was an old mangled ferrel tom cat she tamed attacked and dragged away by a fisher. There was blood, urine and feces everywhere. Everyone felt sorry for "the reverend". He lived under the old abandoned church next door, hence his name. Wouldn't you know it. That tough old cat showed up a few days later all chewed up, but alive. I'm guessing that he was rendered unconsious by the attack and dragged off to be eaten at a later time. Then came to and eventually made his way back.
People are being very cautious about leaving their cats outside for any length of time at night.
A number of years ago I caught a long tailed weasel, AKA Ermin by hand, wearing a welders gauntleted glove. He had his head in a plastic bag full of deer scraps. First surprise was that he sprayed like a skunk. Yep, skunk family. The second was the ferrocity of the little beast. I have to tell you that this little animal, pound for pound, HAS TO BE one of the strongest animals I've ever encountered. It felt like a solid muscles squirming in my hand. If I would have let him go, he would have run up my arm and probably ate my head off. He was seriously pissed off. I ended up smacking his head against the concrete in front of my shop. Knocking him out but unknown to me, not killing him. I put him on top of a 55 gal. oil drum and went about my business. A friend that was there asked where I put him, because he didn't see him anymore. He had bailed off the drum into the leaves below. I found him by kicking the leaves around. He ran out across the concrete slab, where I stomped him. Standing on him with my 200 Lbs didn't even kill him. He squeeked and squealed. my frend stepped on his head finishing him off. Now imagine this. Someone parking a truck on your chest and you still being able to breath and yell ! Talk about tough. Now imagine doing battle with something that is the size of the fisher. WOW !!!!!
Just so you know, he is now mounted on a piece of driftwood with a 23 pound female bobcat and a squirrel. The cat is standing over its squirrel kill, snarling, showing it's teeth and swatting at him as he calmly sits there contemplating stealing it. I designed the scene myself and had a local taxidermist do it for me. BTW, I shot the cat with my Ruger Redhawk pistol at about 70 yds. When I killed it, it had a rabbit in it's mouth. That's where the squirrel idea came from.
Stay Safe,
