I live in Britain where wild cats are native so I don't think a few domestic cats are going to cause total devastation.
Man made cats (selectively bread, designed and created by us) are not the same as wild cats. For example, there's many diseases and illnesses that occur not in "real" cats, but these man-made tamperings with nature. We want cats without hair, so we bread bald felines prone to horrible skin conditions. We want dogs with cute faces, so we bread dogs with small heads that suffer premature death an order of magnitude more often than their natural cousins. Etc., etc.
You introduce an organism to an environment it doesn't belong and you upset a very long, very old and very important chain.
