Fred used to live down the street until his family moved. As Fred is a confirmed wandering tomcat, the neighbors didn't feel that he would do well in their new apartment. I agreed to put out feed for him and the rest is history. Fred happily moved down the street and now hangs out at my place.
He was very helpful during the coop building.
Fred mostly ignores the chickens unless they are running about squawking. Then he does feel obligated to run amongst them. Mostly though he just hangs out and watches. He guards the front yard and occasionally goes off and does Fred Things. I have no idea where he goes or what he does. He shows back up after a couple of days and will hang around for another few days before he goes off on walkabout again. All in all, Fred is a good cat.
