When Zachary is out to buy cat food he meets Marilee, a veterinary student, who gives him advice on what food to get. Their paths crosses on several occasions while Marilee first loses her extra job at a pet store (at the hands of Zachary's girlfriend) and then her apartment (when the landlord finds she houses a cat). Zachary who feels guilty over her losing her job offers Marylee to stay in a house that he's currently restoring to flip. While living there it's not only their cats who finds each other.
