I like the term "tux wannabe", my cat is also one but with extra white! Well, actually my cat is half black and half white so she is really a "moo cow kitty".
Abby is beautiful with her big gorgeous eyes, and what I call a "headlight" on her chest because it is so hard to see a black cat in the dark other than their eyes.
My in-laws used to have a black cat with the white spot too. I think a little white makes them more unique.
