I know they use to kill my friends barn kittens. Last night I had a opposum on my back porch trying to lick up the remains of feed out the bottom of a bucket. Then today I seen a ground hog come out of the woods. As soon as the dog started barking it ran back into the woods. I was wondering if they killed chickens? I know they dig and climb. I had never seen one climb a tree until my dog treed one. I know they are very good diggers.
