With a pointed and sharp knife, serrated edges are useless here, slit the cat backwards from nave to chops, then forward from nave to neck, stem to stern so to speak, peeling outward as you go. The way they used to do it in the old days. You have to get the skin away from the flesh. This is difficult, but masterable. Also be sure to slash from the inside of the paws along the legs for a superb pelt.

Me, I find it more sporting to use scissors. It is easier for me lunge forward with scissors. I have to make certain on the first slash. With the incisor blade prominent, I bring it down hard on the receiver blade. I must do it right the first time. There is never a second chance. Do it properly, and with style. What else is there?
