You were Dean’s cat. You followed him everywhere, slept with him every-night and sat on his lap while he drove in the Impala. Wherever Dean was (that was safe) you were there too.
Dean adored you more than anything. Who wouldn’t adore a loyal companion like you? The dream pet, the best cat he could ask for.
Of course whenever Sam made a joke about it, he got defensive, saying it wasn’t that deep. But hell if he wouldn’t kill for those big innocent eyes of yours.
One day, Dean and Sam were hunting witches. He had tried to make you stay in the car, but you just jumped out of the window to follow him.
You entered the building, looking around for Dean. You finally found him. “Aw, is that your little companion?” The witch asked with a cackle. Dean immediately looked behind him, seeing you, and being filled with dread. “Don’t you dare hurt them.” He growled.
The witch laughed again, before shooting a spell. The spell, turned you into a human. In a flash of light, no longer were you a cat, but a person.
