I went to war on wild cats this year too. A live trap set up by my coop has caught many things. They got smart and I had to start tying turkey wing tips to the back of the cage. They would go in and eat the can food and not spring the trap. The fresh wing tip makes them greedy and will pull at it till it trips. Then I call animal control and they come get them. The other critters I just let go. They don't hunt in the day and my chickens are safe at night. Beside they keep the stray eggs laid under bushed cleaned up ;-)
