I have many feral cats in my area. They kill and eat anything that moves that they can catch, lizards, birds, mice, vols, little rabbits. I’ve feed and tamed two of them. They are mice killing machines.....even when fed daily.
Our kitties generally bring their catch in alive. It amuses them to let them go & watch US chase them. Certain garden snakes have gotten so use to the routine they actually curl up in my sweetie’s hand as he carries them back outside.
