We have coyotes, foxes, bobo cats, raccoons, etc, etc but the only thing I have ever lost livestock to is stray dogs or cats. The wild animals respect the electric fences and are a lot more cautious of possible danger. The domestic strays have no fear and kill for fun not food. Hope you get your guilty party. You know your a homesteader if you don't realize your naked until your half way in the woods with a flashlight and gun but no cloths or shoes.
