Mickey's Orphans (1931) Mickey Mouse. At Christmastime, Mickey Mouse, Minnie and Pluto are beset by an enormous litter of bratty orphan cats. Christmas; Mickey and Minnie are singing carols. Someone drops a basket on the doorstep that has what seems like hundreds of kittens; they quickly overrun the house. Mickey dresses as Santa, with Pluto as a reindeer, and brings gifts for the kittens.
