That would definitely be 'Rock-A-Doodle'..
"A little boy named Edmond learns that the crowing of Chanticleer the rooster did not make the sun rise, as everyone thought. But when a flood threatens his family's farm, Edmond sets off to get Chanticleer to make the sun rise and save the day or the rain will keep coming down forever. Edmond gets turned into a kitten during this adventure, for no apparent reason other than that cats are easier to animate than humans. Meanwhile Chanticleer has moved to the city, and although the farm seems to be in the Midwest, the nearest city is clearly supposed to be Las Vegas. Chanticleer is now the King and now he has to hurry, because the horrible owls, who love the darkness, are coming." Written by Anthony Pereyra firstname.lastname@example.org
