Mara Bennett, a white-collar worker in New York, and Ethan Cole, a product manager at a tech company, have been married for three years, but their marriage is as cold as a roommate arrangement. That is, until one day, Ethan brought home a little white female kitten, doting on her like a precious treasure and adamantly refusing to let Mara take her to be spayed. At first, Mara just thought her husband was being odd, until she came home early from work and saw a gray-and-black male cat climb in through the window and become intimately entangled with the white kitten.
