I would try to use something to attract their attention so you dont need to worry about a fast shot. Back on the farm when I was a kid I used two chickens that were raised together.(you use these chickens because the will try to get back together, making chicken noises
) Put them in seperate, small cages about 20 feet apart. Then sit in good shotgun range and wait for the chickens to let you know when they are there, and they will. Hit the light and bam. Works good for yotes, bobcats, fox and coons. Might want to check on the legalites too. Todays world and back when you had to protect the farm critters are two differant things. I have used everthing from buckshot to #4 on them. My favorite is #4 buckshot. Pattern your gun, see what works best.
