In January 2013 in the episode "Star-Spangled Tori", Cat's parents move away to Idaho to be with her mentally ill brother at a mental institution for between six months and two years where the doctors can make sure he receives much mental relaxation and cannot escape and keep him institutionalized. Her parents couldn't take her as it was in the middle of the school year and wanted her to stay in Los Angeles and sent to her Uncle Walter and Aunt Pearl, while they are in Idaho but according to Cat, they are very strict and mean. They do not like her red hair, they only eat vegetables, they said she cannot have unlimited texting, and they will not let her flush the toilet unless it is "necessary". This caused Cat to run away and take refuge in the attic of Hollywood Arts' BlackBox theater, where her living habits were discovered by Robbie and Jade. After Jade called up Cat's parents, Cat goes to live with her grandmother – who turned out to be living in Venice, California and not Venice, Italy as Cat had initially thought – until her parents and brother return. She refers to her grandmother as "Nona".
