I would describe him as a black and white domestic shorthair. Yes, you can also use the term "tuxedo" to refer to his pattern. "Tuxedo cat" is an informal term that refers to cats that are mostly black with white markings on the chest, belly, and often also on the feet and chin. We had several tuxedo cats when I was a child, and I always loved how they really do appear to be dressed in formal wear
Tuxedo cats generally have just one copy of the gene for white spotting. The same white spotting gene is responsible for the white markings of cats that have just a little white (such as tuxedo cats), and cats that have lots of white (such as van pattern cats).
He is the most friendly boy ever. We adopted him from the RSPCA. His mum was a very young tortoise shell who was found with a broken jaw and leg and had a litter of 5 kittens
