She Wees on the Bath Mat Every Morning is for the cat owner who wakes up, walks into the bathroom, and finds the same wet patch on the bath mat for the third morning in a row. The repetition is the clue and the frustration: one spot, one time of day, one routine, but no clear reason. This book does not diagnose, does not name treatments, and does not promise a fix. Instead, it helps the reader treat the bath mat as a data point rather than a personal failure, gather the right observations, rule out the possibilities that need a veterinarian, and adjust the bathroom setup and morning routine so the pattern has a chance to change. It covers the 2am decision between a vet appointment and a litter box problem, the observation log, the vet visit as the first fork, the bathroom setup, the litter box audit, the morning routine, quiet stress signals, and when to involve a qualified, force-free behaviorist. A sudden change in behavior, especially litter tray problems, hiding, or a cat who has stopped eating, is a reason to see a vet first, because pain and illness present as behavior in cats, and a cat who stops eating needs help quickly.
