My son's fiancee called theirs Bowie after you-know-who! So now they've just moved house from a top floor city flat, where Bowie could only get outside via 2 cat-flaps to a house in a rural location, where he can roam and hunt to his heart's delight. Bowie is probably thinking "Is there life on Mars?" Or maybe he's transformed into Major Tom if there are any lucky lady cats about?
