As everyone knows, all cats are aristocratic nobility! But not all aristocrats are made equal; some cats are more noble than others.
You're one of those special cats, the crème de la crème of feline-hood.
Cat-Lord 0: You're either a regular cat or a person wearing cat ears.
Cat-Lord 1: You are a mere kitten. A sovereign among your people, true, but less of a Queen and more of a Princess. Your authority over your feline bretherin is fairly weak; most of them wouldn't deign to obey anything more than the most trivial of tasks.
Otherwise, you possess all the awesome power of a kitten.
Cat-Lord 2: You are a young, rising star in the cat world. You're still basically a housecat, but somewhat more cunning, more adroit. You are stealthier than any mere housecat, and they recognize your power. Most tame cats will obey your wishes at least some of the time, but your wilder cousins may well laugh at any attempts to exert your fledgeling power.
Cat-Lord 3: You are a some kind of wild cat, like a lynx or an ocelot. You are a king as far as your lesser kind go; little house cats and feral cats obey your mandates without question. They spy for you, if you ask it, bringing you the secrets and shames of their human companions. You are an avid hunter, a quiet stalker and cunning enough to speak the tongue of man.
Cat-Lord 4: You are a great cat of some sort, like a lion or a panther. All feline-kind bows before you. You know many secrets, understand many mysteries. You could kill even the mightest of beasts with ease, and vanish like a whisper into the darkness. Your existence is myth, your knowledge is legend.
Cat-Lord 5: You are the ur-cat, the first cat, the dream from which all cats were born. You are the plan by which all cats are derived. You are unquestioned. What could face your claws, your teeth? What could find you, who could disappear in broad daylight as easily as a shadow into the night? What secrets could you possibly not know?
