Gus’s real name in Disney’s Cinderella is Octavius.

Quick Scoop: Why “Gus”?

In the 1950 animated film, Cinderella rescues a new mouse and decides to name him Octavius, then immediately shortens it to “Gus,” which becomes his everyday nickname. This is treated as a little in-joke by the writers, since historically the Roman Octavius later became Augustus, which can be shortened to “Gus.”

So if you’re wondering what to say: his real name is Octavius, but everyone calls him Gus (or Gus-Gus). 🐭
