The Father Cat and his wife, the Mother Cat appear to be two cats with white fur, light blue eyes. They are Kitten's parents.
The cats first appear when Furrball looks into the window and sees their daughter rubbed by their owners' daughter. After their owners leave to take walk with their daughter, Furrball gets into their home. When he tries to be friends with the Kitten, her Parents see him and look angry at him for coming into their apartment. When Furrball continues playing with kitten, the Father Cat attempts to get him to leave the home until his owner kicks him out.
