 So like a cat deciding to go pee-pee where they're not supposed to go pee-pee. You have a cat that knows there's a litter box, knows there's a litter box, but decides to go poo-poo on your bed or pee-pee on your bed or on your favorite dress. They're trying to get your attention. Either they're ill, they're not feeling well, they don't like the food you served them, or they just want to get your attention.
