Stuart Little 4 Finding Margalo is an upcoming film, split into two parts, the first releasing December 25, 2024 and the second releasing December 31, 2025.
In September, 1999, a cat, named Ace Cat, is born to Mr. and Mrs. Cat, two street cats, in Queens. Ace soon befriends an orphaned street cat by the name of Monty. Around late November, Mrs. Cat runs off from Mr. Cat and Ace, having sought out another cat. Ace is devastated. 
On December 31, 1999, Stuart's parents, Eduardo and Clara Mouse, are doing some last minute New Years Eve shopping at Velazquez's Verdulería, in Brooklyn, where they are ambushed by a kitten Angora Cat. During a scuffle between Eduardo and the cat, Eduardo is knocked into a section of stacked cans of soup, causing them to fall over, killing the two mice. The cat flees, and Stuart, who is never picked up from daycare, is eventually placed in an orphanage.
In July 2001, Ace, now a teenage, meets a female Angora cat, later revealed to be the same that killed Stuart's parents, who is now a teenager. Her name is Menika Angora and he is smitten with her.
