Another thing I know is that The Catillac Cats was originally going to be the whole show, but they later made it about Heathcliff with the CC being a back-up segment, because the Heathcliff people were looking around for someone to make a new show for them and approached DiC. So the two things combined into one show. It's possible that Mongo, Wordsworth, and Hector might not have even existed if not for this, either, since they were created specifically as characters that would appear in both segments to tie them together. Though, after season 1, they stopped appearing in the Heathcliff segments altogether.
