I am wondering how much I need to worry about neighbor cats as a threat to my chickens. During the day they basically free range in my vegetable garden (it's been such a cool summer I haven't gotten much out of the garden anyway) and my Great Pyrenees pretty much keeps the cats at bay. But at night we bring in the dog due to his barking habits, and I have found cat poop in the sandy areas of our yard--not by the chickens though. I was just wondering how concerned I should be. Thanks!!
