Do you have a picture of your kitty? You have general body types that may give you a clue as to some background.
If the body is long and skinny (tubular) and the cat talks a lot, it probably has some oriental/siamese type of cats in the background.
If the body is more rounded and medium build you would have an american shorthair or british shorthair or a few other medium build type cats in the background.
A short, cobby body/legs would indicate persian or exotic shorthair (which is basically a shorthair persian).
So you can see that black/white is just a color and not a breed. If you have a picture, I can help you guess what might be in the background
