The cats belong to a neighbor. It doesn't bother anyone that they roam around. He's had them for about 4+ years. Of course no one is bothered by my hens & rooster either. Basically, we have great neighbors here, so I don't want to make an issue. I just got a little nervous while they were "watching" my chickens, because the cats rarely come close to our backyard. Good to know that cats normally prefer smaller/younger animals & that a chicken would fight back. The coop/run is very secure at night, but during the day, the chickens free range within a fenced yard.
Thanks everyone.
