# Why Is My Cat Pooping Outside the Litter Box? — Quick answer

PETHEALTH+ (https://pethealth.org.uk/uk-pet-questions/why-is-my-cat-pooping-outside-litter-box-uk): Why Is My Cat Pooping Outside the Litter Box? — Quick answer. Cats rarely toilet outside the tray out of spite. Medical pain, diarrhoea, arthritis, stress, and poor tray setup are common UK causes. Book a vet check first — then review tray number, cleanliness, litter type, and household stress. Sudden change in a previously reliable cat always warrants investigation.
