Mom Cat
Mom Cat (surname Cattenheimer) is a Lightner in Deltarune. She is the mother of Catti and Catty, and the wife of Dad Cat.
Mom Cat is a white anthropomorphic cat-like monster with a tall purple beehive hairdo, a simple long-sleeved purple shirt or dress, and a yellow necklace with large beads. Her design could be a reference to Marge Simpson from The Simpsons.
Mom Cat is cheerful and caring toward her children, cheering them on at every opportunity.[1]
According to Dad Cat, her cooking consists primarily of frozen cat food, which is disliked by Asriel.[2]
While Mom Cat does not appear in Chapter 1, she is briefly mentioned by her husband.[2]
In Chapter 2, Mom Cat appears in QC's Diner, where she enthusiastically cheers for Catti while waving around a large red foam finger with "#1" written on it.[1]
In Chapter 4, Mom Cat attends church alongside her husband and Catty, cheering them on for their choir singing and reading recital respectively. Afterwards, she and her husband get stuck in a tree by the library, with Catti constructing a plan in order to get them down.
