How can we tell if a cat is suffering? What are the root causes of feline aggression? And how can we treat patients who can't speak for themselves?The relationship between humans and cats has never been simple. Cats are mysterious and contradictory, independent and affectionate, predator and prey. Their true nature continues to elude us, and their subtle and complex behavioural problems can often seem unsolvable or incomprehensible.In this ground-breaking book - a huge bestseller in its native France - veterinary doctor and psychiatrist Claude Béata draws on cutting-edge research and decades of experience with cats, to revolutionize our understanding of pets and transform our appreciation of feline mental wellbeing. Here, we meet Nougatine, a Siamese suffering from bipolar dysthymic disorder, Tabatha, an anxious Ragdoll with attachment issues, and Melly, an Abyssinian struggling with a feline form of schizophrenia - as well as their owners who seek advice and support.Providing fascinating insight into a range of disorders, Béata calls for greater compassion and offers an alternative understanding of cat behaviour to help us care for the mental and physical wellness of our beloved pets.
