I always thought the silent cat's name was 'Giddy'.
Each time Honest John spoke to him, it sounds like he says "Giddy" instead of "Gideon"( think that's how it's spelled).
He does say Giddy. It's short for Gideon. Like a person named Joseph being called Joe.
shareJust like how Pinocchio calls Lampwick "Lampie"
Jiminy calls Pinocchio "Pinoke"
They're nicknames
