Without actually seeing a picture of your cat, or knowing if he has a pedigree, I would assume he is probably a black and white domestic shorthaired cat.
I call the cute little black and whites "tuxedo kitties".
I would love to see a picture if you have one!
By the way, welcome to The Cat Site Forums. We will look forward to hearing more from you!! If you haven't already done so, check in at the New Cats on The Block Forum and introduce yourself.
Thanks for your post,
