We live next to a conservation area with a large lake and lots wildlife including various rodents, snakes, migrating water birds etc. Our neighbours have two cats that are left to run wild 24/7 with no bells, killing this wildlife (and stalking my chickens). We have brought up the subject of putting bells on them on a couple of occasions - to at least give the 'locals' a chance - we were told "It's dangerous, no-one knows just how many cats are strangled by their own bell collars every year" Oh, that's alright then - as long as your overfed cat's are ok! Should we persue this? Since moving here, we have taught our hunting dog to "leave" anything that comes into our garden - this includes ducks, foxes, rabbits, pheasants, doves, snakes. Everything that is except CATS!
