My three cats have never caused me problem, but I once came up the stairs of my house to find my fifteen month old stamping on a box of minis like he was crushing grapes. Luckily they were just Mantic's restic minis and still looked just as bad after I repaired them. My son was still asked to leave, on principle, but my wife overruled me. He's four now, and still lives under my roof, but his cards are marked.
