This is pretty old news, and died down a while back here. It was a big fuss at the time, mostly blown well out of proportion by the pro-cat people. Morgan suggested that people consider not replacing cats when they die, that efforts be made to keep them indoors, neuter, maybe a bell on the collar to warn potential prey, and that efforts be made to reduce feral cat numbers, and he put out some statistics on the numbers of wildlife they kill. However, he did use some ill advised and sensationalistic terms like "serial killers" - however, he's probably smart enough to have been doing so because he knew it would draw attention to the issue. On the whole, everything he was proposing makes perfect sense, but a very vocal group got up in arms as if he was raising a posse to come into people's houses and shoot their moggies.
