Stuart Little was successful enough to spawn two sequels:
The main conflict escalates when the Littles realize that another mouse, who claims to be Stuart’s biological mother (but is actually a con artist working with Snowbell), has "found" him. Stuart, heartbroken, leaves the Littles to find his "real" family, only to discover the ruse. With help from Snowbell (who has a change of heart) and a friendly St. Bernard named Monty, Stuart escapes the clutches of the alley cat gang led by Smokey and returns home, where the Littles officially finalize his adoption. stuart little 1999
