On our TN farm the feral cat population has skyrocketed over the past few years, they are killing our doves,pheasant,quail now we don't raise them for damn cats to kill them. What do you think would be good for these cats would a .22lr hollow point to the head do the job? The warden said I can kill all the cats I see, he also thanked me for wanting too. He agrees the population is out of control on farmland, and he gave me permission to exterminate them. What are good ways to get rid of them with a rifle. Like bait or something?
