Where we can conceive of using pee or poo as a weapon to annoy, or as an expression (albiet very antisocial) of displeasure, cat's don't use that kind of logic. A cat does not deliberately pee or poo someplace in order to get revenge or to express anger or discontentment.
Tell this to my neighbors. Their cat gets upset every time they start packing for a trip. They have to hide their suitcases or she'll relieve herself in them as a form of revenge.
