Allow me to buy you a clue:
Hunters trespass on land, regardless of signs or no signs. And no, I don't patrol my property 24/7 to catch people who abuse the land. Neither does the sheriff.
The bodies of dead people fill pages, shot by hunters who are "sure" of their targets.
Ditto for damage to fruit trees, fences, houses and buildings.
Hunting cats will multiply these problems.
Now let's see your proof that more anti-hunters post their land than hunters. And 80 by 100 ft yuppie lots don't count.
The fact that people tresspass has nothing to do with allowing the hunting of feral cats. By not passing this law, tresspassing will not go away. The two are not related in any way. People who do not hunt other game are not going to take up cat hunting, so the number of people that would tresspass would stay the same.
Pages of people shot by hunters? If it averages more than 2 per year in WI I would be shocked. Several years no hunters died even from heart attack or other causes.
Well almost all anti-hunters I am aware of have their land posted. Yes hunters post their land also, but that is to preserve it use for themselves and not the general population. I have hunted all over WI, for a very long time, and never been refused after asking permission.(From a property owner who is a hunter.)
