Cats have an interesting way of letting you know who’s boss.
If they leave their feces uncovered, they’re trying to show you who’s boss, especially if there are other cats at home. This comes from their wild ancestors who marked their territory and demonstrated their power over others in that way. Another “symptom” that indicates who’s in charge is their need to control all your movements.
I have a black cat, his name is Spot, he's not happy unless my arm is bleeding from several puncture wounds for "loving me so much" in the morning.
