History WMG / StuartLittle

* This theory is also [[https://youtu.be/bzThDWTAZYs?si=h660HbfnRuiJSA_x backed up]] by Leo Vader after an exhaustive review of the movies, the animated spin off series, and the original source material.

In the first movie, while surprised at first, the Little Family wholeheartedly accepts Stuart as on of their own, with the only exception being George, but even then, George's main problem seems to be that he has trouble seeing Stuart as a brother, [[ComicallyMissingThePoint not the inherent absurdity of his parents adopting a literal mouse.]] No one else - the police, other animals, or the lady at the orphanage- seem put off by Stuart's presence. When two mice show up claiming to be Stuart's biological parents, the Littles are more sad to see Stuart leave then shocked at the two talking mice. The police even talk about a "mouse killer" while Stuart is missing, implying that murdering sentient mice is seen as an ''actual crime.'' Perhaps, in this world, sentient animals are an UnusuallyUninterestingSight that live their own lives under humans and only warrant mild surprise. Sometimes, interspecies adoption happens (going by the film's plot and the word of the lady at the orphanage, who even says that they try to discourage adoption between different species) but its typically rare because of the emotional dissonance it can cause, as Stuart spent the entire first film being afraid of not fitting it or being really human.

* He was somewhat right about being annoyed in that movie, though. For one, despite having chickened out at some point, he was instrumental in both Stuart and Margalo being alive by the end of the film by finding Margalo trapped in a paint bucket in the top floor of a skyscraper and releasing her, when he went with Stuart to look for Margalo. He also was right next to the Littles, just outside the taxi, when they were out finding Stuart, not even paying attention to their own cat. Not to mention he was there because the Falcon had thrown him down from the skyscraper inside a paint bucket.

The Littles just ignore him most of the time because he tends to be a whiny DramaQueen. I thought this because of a scene from the end of movie 2 - when the Littles are headed home, Snowbell whines that he's sick of never getting any attention and claims that he's not returning home with them. Cue Mrs. Little calling out to him (in a perky but ''slightly'' annoyed tone) that she'll make him dinner when they get there, prompting him to join them. Additionally, Margolo can talk to humans and no one seems to bat an eye about it. It's possible that sentient talking animals are commonplace in this universe.

They're both the same breed, and have the same voice and temper.

* His parents were the ones who were experimented, and passed it onto him.

* Well, scientists have using white mice in experiments for years.
