In "Puss Gets The Boot" the cat is clearly named "Jasper" but in other cartoons his name is with out a doubt "Thomas." As to my "Mammy" question, I've seen her referred to as both a maid and as Tom's owner. I assume this is correct because in the years the cartoons were created they wouldn't have portrayed a black woman as anything but a maid. However, since when were maids allowed to have pets? In later years "Mammy' was repainted as a white woman and her voice was re-dubbed as well.
