Dude, I know these fuckers well...what you need are porcupines...lots and lots of Porcupines.
Porcupines are the Fisher cats main prey (one of several actually, but It seems to prefer the Internal organs of porcupines because they are more oily than other shit it eats. But the thing with porucpines is, one out of every four encounters ends BADLY for the Fisher Cat (either maimed or even KILLED by the porcupines barbs) You will need to muster a 1950 November Yalu River Chinese People's Army In Sneakers Wave attack of Porcupines, but hey, you wont go to jail as opposed to firing guns.
Seriously, you need a Professional Trapper, these critters are suckers for Smoked meat not-to-cleverly disguised in miniature guillotines....Call one of the places up in Canada that still trap animals for fur...I'd suggest a do-it yourself Trapping kit but you need both your hands and all your digits since you were just married and you no doubt have to make Presentations in front of self important dunderheads. Nothing detracts from a presentation more than a speaker with three fingers on one hand manipulating the laser pen light and everyone wondering "Do I give him a High Three after this lecture??"
