Scottish Fold
Topsy is a grey/brown Scottish Fold kitten. He is one of Tom's alley cat friends/foes, although in "Professor Tom" he befriends Jerry. He first appeared in "Baby Puss"; his final appearance in the original theatrical shorts was in "Scat Cats". He also appears in "Tom and Jerry Tales" with a more yellowish color (similar to "Life with Tom"). In "Professor Tom", Topsy is explicitly a house cat; more often (as in "Saturday Evening Puss" and elsewhere), he is depicted as an alley cat or a cat of unknown origin. In the live action film, Topsy is voiced by Harry Ratchford.
