I have Ccat confidential but haven't read the others so don't know how it compares to them. Chapter headings are: The New Kitten (includes stuff like litter training, introductions), The Scaredy Cat (about personality and timid cats), The Aggressive cat (different types of aggression and case histories), The Indoor Cat, The Multi Cat Household, The Weird cat (unusual behaviour), The human/cat bond, The elderly and disabled cat and Coping With Bereavement.
Hope that helps.
