The anthropomorphic traits of the mice around Cinderella's house are a result of the Fairy Godmother's magic.It was something she [the Fairy Godmother] set up so that the poor, practically enslaved girl wouldn't be lonely.
The anthropomorphic mice are the ancestors of all the mice in the various Mouse World movies.Cinderella gave clothes to the mice and taught them to talk. Given the high reproduction rate of mice, the descendants of these mice spread all over the Earth, probably also teaching the other mice to dress and talk. By the end of the 19th century, they had a whole kingdom in England, and communities in Russia. By the late 20th century, they had a global society protecting humans, as well as rogue organizations that did the same. One wound up in the hands of a human and became much like one.
Or maybe they're off-world explorers from planet Altea...Because why not! After all, some of them were friendly with an orphaned princess...
Cinderella dreamt the entire thing up starting when the fairy godmother appeared and actually committed suicide while her stepfamily was at the ball, just so she could die feeling happy for once.Because the Grimm version just wasn't sad enough.
The Prince has really poor eyesight, maybe blind, which is why he can never identify Cinderella on sight.He just pretends to see, calling Cinderella beautiful and such, and has been trained so well to pretend he can see that it is as if he is not blind to all outsiders who don't know. He can also sense what people are like.
Lady Tremaine murdered Cindy's father

Cinderella is a reincarnation of Aurora.
Lady Tremaine later reincarnates into the ContessaProvided that it's possible for the Fairy Godmother to open gates into other dimensions, Lady Tremaine and Drizella were given an escape clause on Cinderella's request following the third film. This clause is banishment into another universe - one populated exclusively by anthropomorphic animals - which is permanent. They took it out of spite, and were given new forms to suit their darkened hearts: black widow spiders. Tremaine then marries a rich man and kills him soon after their wedding, and joins Interpol and the Klaww Gang, becoming the Contessa as a result.
