I had a fellow at the pound tell me the best and cheapest way to get rid of them is to just quit feeding them. He said they will go somewhere else before they let themselves starve. I had someone else tell me if you just feed them a time or two they are your cats now and you are responsible for their rabies shots and if they don't have them when the man comes around you could be fined or have to pay to have them vacinated right then and there. That boils my blood. Sorry to have to tell you that. Having critters around isn't as simple as it used to be. Since you are trying to catch up to me in age I guess you well know that nothing is as simple as it used to be.
