McMillen explains that in Mew-Genics, cats will have varying personalities when they're born, "from lazy to sexy, from passive to psychotic." Personalities are influenced by items and furniture, which McMillen detailed the function of earlier this month. If a piece of home decor is rare, it's also possible the cat will identify with it so strongly that the cat will mutate and an element or design of the item will become part of the cat.
In one screen, a cat that identifies with a Super Meat Boy doll has the same black eye and missing tooth as the hamburger hero. In another, a cat that identifies with gangster rap has a tattoo of a knife on his cheek and a bandana on his head.
Again: there is a cat thug with a bandana and knife tattoo on his face. I ... I don't know how to end this post.
