I won't get into my cat story right now, but suffice it to say the deer population is in check for the first time in years and ruffed grouse are less plentiful than a few years back. I know the cats are here, but they leave me and everyone else alone. They are quite nomadic and will move with their food supply. I don't worry about them any more than I get nervous about having 400 pound black bears take things out of the barn. I know they are both here. We all live in relative peace. Nothing is 100 percent safe- including life. I don't mind sharing space.
Sometimes it is necessary to protect life and property because of an ill animal, but those are rare exceptions. Some guys will kill a mother bear when she stands up and is confrontational, but then the bear cubs climb down the tree next to her and mourn her death and are orpaned and probably doomed. A pasture behind my vineyard has had a few cows killed in it in the past 10 years. Those were years of downturn in the native deer population. When the deer were totally gone for a few years, so were the cats and then no more dead cows. Plenty of deer, no cow problems. Keep them in balance and they could care less about humans.
