Worshipped as gods, feared as demonic servants, seen as both wild opportunists and beloved companions, cats often seem as unfathomable, enigmatic and magical to us today as they did in ancient times. They have lived with humans for at least ten thousand years (far earlier than the reign of the Pharaohs), and today are the most popular pet in the world. That they now outnumber the dog, man's 'best friend', by three to one, is small wonder: at once affectionate and self-reliant, they seem to be perfectly suited to our busy 21st Century lifestyles. Yet cats still think like the wild scavengers and hunters from which they are descended - and to which they can quickly revert. Today, they face unprecedented challenges in their life with humans: from conservationists who cast them as a threat to wildlife; from other cats who they compete for territory with; and from good-intentioned owners and vets with misconceptions of what they require.
