The world of cats - their instincts, tastes, perceptions, abilities and relationships - is explained by a leading authority on pet behaviour. The development from kitten to cat, interaction between cats, the similarities between the pet cat and its wild cousins, hunting and feeding, and the relationship between humans and cats, are all considered. Other issues discussed include the relevance of sight and sound to the hunting cat, why cats don't need to drink water, whether cats can count, whether they talk to each other, and whether they love their owners.
