Discover the Cat of the Night and the Cat of the Day. Over the centuries, the relationship between cats and humans has been one of profound change, of both darkness and light. In Ancient Egypt, we worshipped them as the physical embodiment of a goddess. In Medieval Europe, we tortured and punished them for being the familiars of witches. In the twenty-first century, we are obsessed with filming and posting their antics on social media. And while we may think of them as our pets, that doesn?t mean that we are in charge.
