Bet he's part Siamese - a lot of the coal-black pouncers with large upright ears have a Siamese parent. (Genetics too complicated to discuss in detail . . . but if you cross a Siamese with an ordinary tabby cat, the offspring will usually be black . . . unless the tabby cat had a Siamese ancestor too, in which case 3/4 will be black, and 1/4 Siamese coloration.) Lots of cats have Siamese crouching somewhere on their family tree, because the Siamese boys are great lovers and great fighters . . .
