Love them or loathe them, cats are remarkably popular as pets; according to John Bradshaw in his book Cat Sense, domestic cats outnumber dogs by three to one, so chances are most people encounter them on a fairly regular basis. Unlike dogs however, who tend to be overt with their displays of affection and emotion, cats are often difficult to read; the purpose of Cat Sense then is to dig a little deeper into cats as a species in order to try and help cat lovers understand their feline companions better, and as a result make the lives of both cats and owners a little easier.
