Doesn't take much effort for the farmer to tell you no hunting either. Actually, probably takes less effort.
In most states people will just shoot the cats because there is no law against it or they don't know that it is against the law. As far as not shooting a cat within 1 mile of a farmstead or buildings... Good god, around here you would have a hard time finding one of those place..Especially with all the grainstorage areas that farmers keep cats at to keep the rat populations down. Our barn cats are personally spayed and neutered so we don't get to many and ours probably don't wander more than 1/4 mile from the house. But they hunt our hay piles and do one heck of job during the winter cleaning out the barns of rats and stuff. Almost never see rodents or rodent sign on the 10 acre main sight. Also almost never see my cats with any bird other than a Starling, another invasive non native species. The Starling population isn't hurting so the falcons are doing just fine.

Don't live in Wisconsin but I know way to many people who get their kicks off of killing cats. I will never understand it. I hear the same arguments around here that it is the cats killing everything from pheasants to foxes (Killing the prey) to the hawks not having enough. Than, 3 days later the same person is blaming the hawks for killing all the pheasants and than come winter you have to kill all the coyotes for the same reason...You almost want to say to them "well, which one is it? Is it all the hawks, all the coyotes, the foxes, the owls or the cats?" They don't want to hear that one of the very real reasons game bird populations are down around here is becasue instead of having 40 and 80 acre fields with fence and hedgle lines all over the place the fields are now 320-640 acres with no fences, no hedgelines and no brushpiles laying around. We added a bunch of fence around our ground and in the meantime had to doze out some scrub trees. People kept asking when we were going to burn the piles and the simple answer is never. Our rabbit and bobwhite and pheasant (A non native animal that competes with the native Bobwite for food and shelter.) populations have exploded in the past 4 years on the gournd surronind these brush piles. Even neighbors comment on it while they drive by and wonder if we are planting food or something for them. Habitat is everything.

I should add that our feral cat population around here is very, very low and most people I talk to around here see the same thing. It seems to be the town folks who think the cat populations are out of control in the country while the farmers who are out in the fields don't see many at all. In fact, a lot are havng problems keeping their cats alive because of the coyotes and cats #1 predator, semi's.
