That Darn Cat with Hayley Mills. Each of the Seal Point Siamese cats who collectively play the role of DC are so-called "traditional" or "old style" Siamese, as opposed to the more dainty, long and tubular modern Siamese show cats. One of the cats used for the movie belonged to a longtime cat breeder Edith Williams, a member of the Stud Book Fanciers Association. One of the feline actors also starred, along with two dogs, in Disney's 1963 film The Incredible Journey.
