People often complain: "The cat always pees the bed for no reason; it feels like retaliatory peeing!" The cat often pees on the bed after I go out.
Scratching comes naturally to cats; it's in their DNA. They do it when they play, stretch, or groom themselves, and sometimes cats even scratch when they purr or feel happy. Scratching is not necessarily harmful or aggressive behaviour. People commonly mistake cats for using their claws as a sign of a bad attitude, but that's not the case; they are simply doing what comes naturally to them.
