The cardboard box has always had a sort of magical quality. When we were kids it signified endless possibility. It could be anything from a washing machine to a rocket in just a few seconds. And as adults, it has a different significance. It is a sign of a life change; it is symbolic of moving house, of childhoods packed up into the loft. And occasionally, very occasionally, it is the origin of an internet meme.
Why not give your cat the chance to fulfil his potential with just a box and a Sharpie!
