I've been talking about my new cats at work (adopted two weeks ago, fluffy kitten angels of my heart, I'm well wrapped around their little toes as cat-slave) and the topic of when I was going to first let them go outside came up. Several colleagues chipped in that when I do, I should smear butter on their paws to stop them from wandering off. wtaf? Apparently it's an old wives' tale and not one I intend to try (sounds like a recipe for slippery cat chaos and very greasy floors). How can buttering your cats paws help with them not wandering off and getting lost? Has anyone had experience of actually doing this?
