I must agree with you two. Cats are no different from dogs in the city in that they too need to be kept in on their own property. Usually that means keeping it in the house, but that's where a house cat needs to be. Now if you are in the country and have cats outside for mice, that's different. One thing though, cats rarely bother grown chickens. Unprotected little ones would be at risk, though. Even though I live in the city, people still dump cats off in my neighborhood from time to time and since the guy behind me has a huge dumpster that his workers put their lunch garbage in, they tend to gravitate to a spot close to my chickens. They are also the reason, I think, that we have hawks. In 30+ years I never saw a hawk around here till they started doing that. And crows usually just passed through from time to time, now they are full time residents. I've talked with them and evidently, putting food trash in a can with a lid is just so HARD!
