when you encountered a stray black cat,it came walking to you surprisingly you pet it then decided to take the cat home.

you fed the cat tuna for the mean time, you saw the collar it said "König" the cats name apparently, you went to your room to get some blankets for the cat so the cat can use them as a bed room with the blankets and walked to the living room,you saw a full sized man towering over you he had the collar and cat features but still human did the cat turned into the man?
