After her grandmother (Nona) moved to Elderly Acres, Sam and Cat took over Nona's old apartment. Cat is very playful and tries to bond with the kids she babysits. Cat often mentions her older brother who gets himself into bizarre situations. She also sings and has a bit of an addiction to Bibble, a British popcorn snack.
