I have of course seen them run and treed with dogs (not in person but on TV and in print) but one fellow I know maintains that cats really aren't hard to kill you just need patience and endurance.
He waits until the snow is deep then drives until he finds a fresh track cutting the road. After that he says that all that you need to do is to stay on the track. By the end of the day the cat gets sick of floundering through the snow and comes to bay in some tree or on a rock.
According to this fellow, all you have to do is walk up and shoot them! You don't even need a dog!
Of course you DO have to be able to go cross country in deep snow for several hours...but that's all their is to it!
As fantastic as this sounds, I actually belive him. He's a professional outfitter that seems to know his stuff, so I think he is telling the truth although I really don't have any way of verifying it.
What do you do with those empty nylon feed bags or dog & cat food bags? Can you say recycle? I use them for target practice for the youngsters. Take your empty shopping bags, stuff them into an empty nylon feed bag. You can also use old clothing or rags, (but put them in the bottom so it doesnt get top heavy). When your bag is full, fold the top over, punch some holes into the top and zip tie the top shut. Paint, draw, paste, or have the kids decorate their new target. Set it out 10 or 20...
