Since it is both illegal and dangerous to let Cats outside unattended, I don't quite follow the "Hunting" argument. My cats are well fed and don't need to Hunt. They wear a bell so that no one steps on them. Their collar is a bit of a fashion statement, but mostly so that they can wear a tag telling where they belong in the unlikely event that they get out without me. In fact, their tag says "If I am out, I am lost".
