Cats are good at hiding. This is probably why, in our human stories, we like to anthropomorphise cats and imagine they are in disguise. This probably accounts partly for why cats are the number one suspect when it comes to witches’ familiars. Humans have the ability to ‘know’ something is there, even if there is zero evidence, e.g. witches. We also have the ability to attribute intent where none is there; a bug in our comparatively advanced cognitive empathy.
