That’s a calico cat -.-

So I’m dumb and decided to dig deep (lol) and search up black cats with white spots and Smokey’s mom has vitiligo which will cause her to eventually turn into and all white cat. It’s harmless btw. For Smokey to be grey and his brother to be white, their dad would have to be a white and grey cat. Their dad might be a Norwegian forest cat and their mom would just be a black cat. Since Smokey nor his brother didn’t take on their mom’s black color Smokey is most likely a Korat. Smokey’s brother would most likely also be a Norwegian forest cat but white or an American short hair white cat. Enjoy me digging a bit to deep

Lol
