Ears and head shape show a bit of Oriental and they are known to have long tails. However if you don't know his breeding he's a standard moggie (basically the cat version of the dog term mutt).

If you want to know for sure what your cat might be, then do a DNA test (I had to do that with my solid back cat Johnny because people kept asking me if he's a Bombay and I got tired of the question. Johnny is part Bombay which is a black domestic shorthair mixed with Siamese breeding, but he's domestic short hair mostly.) However Stuart def a domestic short hair, with tuxedo pattern.

And if he's a good kitty does the breed really matter?

Dogs were bred for specific personality traits, shapes and sizes so they would be better tools for humans and many people liked to have dogs from purebred lines to ensure they got the tool for the job, so pedigrees were created. But even when I was a kid in the 60s, lots of people who needed a herding or hunting dog would buy one from someone who raised "purebreds", but didn't necessarily have pedigrees and were actual working dogs doing their thing instead of imposters who only looked like sort of like them and won shows. We used to laugh at the dog show dogs and call them "Miss America dogs" as our border collies and heelers were always muddy from running livestock and theirs were always freshly brushed and immaculate.

Now to cat breeds. They were created in the 1890s out of the desire of the rich European women who collected cats from all over the world like plates or dolls as status symbols to be able to have shows and let everyone see their exotic collectors' items like their husbands showed off their dogs. Cats didn't need reshaping or to have their instincts molded into anything but what they are--premier vermin killers. So the breeds were named after where the street cats these women paid lots of money to have imported were found. Siamese were the strays from Thailand, Persians from the Middle East, Angoras from Turkey (Ankara), etc.

So cat breeds are an imitation of dog breeds without the meaning behind them. Yes, they could have some personality differences, but that's because they behaved however their environment required them to behave and their bodies and coats are different because breeds in steamy SE Asia didn't need undercoats or long hair or a fat layer to keep them warm and cats in Scandinavia did.

Now we're in the internet era and people sell cats online, so of course (just like dogs) everyone and his cousin is out to create the next popular craze in designer breeds. They'll even go so far as to purposely breed what should be culls (I mean they and their littermates and parents should be neutered and sold as pets, not that they should be killed, though that's often what was done in the past). Scottish Folds and Munchkins have an abnormality in their cartilage formation that is like some forms of human dwarfism. Painful forms. Early onset arthritis, sometimes in childhood, with joints that slide around and grind bone on bone....it's cruel torture to breed these on purpose and they should be outlawed. If one crops up in a litter, fine, because these are mutations that do sometimes, but I'm talking about actually purposely doing this to cats for money. It's nasty. I'm sure if the people who bought them knew this they would stop buying them.

Now to DNA testing. Don't waste your money unless you know the cat's parents were some particular breed. I'm a geneticist by training and I can tell you they are little more than guesswork if your cat has more than 4 breeds in it. The tests look for markers that are common to only one (or a few) breeds and the chances of finding those goes down the less of that breed's DNA is in the animal. So your cat could be 1/16 Siamese, but will it show up? Maybe, maybe not. Or maybe that 1/16 Siamese DNA combines with 1/16 Russian Blue DNA and the two markers they find coincidentally together are found together in Persians, so the test says your cat is 1/8 Persian. It's all guesswork. Educated guesswork, but still guesswork.

In the end, a cat is a cat is a cat under the hood. Enjoy him, he's beautiful. He looks much like my late feral cat that was actually trapped at 4 weeks old from a colony in Santa Clara, CA. No telling what's in him, but for sure he's all cat.

Also, as an aside, Bombay cats in America were started in Kentucky by breeding Burmese to black domestic short hair cats with known Burmese ancestry. (Burmese and Siamese and all pointed breeds are genetically black cats with a temperature-dependent form of albinism (cold parts are dark, warm parts are diluted), so they quite often produce black offspring with non-pointed cats).
