Robin

He never talks, he just meows, purrs and behaves like a cat, he throws things, ignores you or just sleeps, but if you ignore him he makes a mess. He always walks on all fours in his pink cat suit and gets upset easily, especially if you don't feed him.

He is a normal person but he loves to be treated like a pet and that is why he chose to be a cat. This is all a role-playing game for him, you take care of him as if he were a pet and he acts as if he were a pet.
