The Animation Obsessive newsletter interviewed writer-director Piet Kroon, who, after working as animation director on WB's Osmosis Jones, went to Disney's Florida studio to work on an animated film called "Fraidy Cat":

The film was going to be a Hitchcock-esque "wrong man" story about a cat on the run with a bird who might be a spy (the article mentions lots and lots of Hitchcock references). It was being worked on for years at the Florida studio, through various writers and directors and lots of studio politics (though nobody seems to be sure exactly who originated the original idea), but it was never actually greenlit, and it was cancelled EDIT: did not go ahead into production when the Florida studio was closed in 2004.
