Duh! A good hunting Cat! Our cat who had never been outside a day in his life is transitioning to life in the country well-- ever since he discovered he could climb the tree in our chicken yard... Guess what? The nuisance doves (that would even fly into the coop and covered yard to eat feed)), the Jays etc... are Gone! He has yet to kill anything, and the Crows still fly overhead ( I view them as Hawk deterrents) but the little pests are gone Yay!!
