We start with a man called Mike and a cat called Ella. Two creatures.
Nothing odd about them, except that Mike has a beard and Ella is a touch chunky. Otherwise, they could be any cat and guy. Except ...
When you think about it, no one is ordinary. You could put a totally bland cat-and-guy couple in front of a hundred people, ask them to look, and each one would see a very different pair, different in a thousand subtle ways, because everybody looks at everything with different eyes.
Case in point: Mike Holmes (companion to Ella) is a cartoonist.
