Your cat is absolutely beautiful, but I'm afraid I don't know what kind he or she is. I'm afraid somehow your post fell through the cracks but hopefully someone will come by soon who can give you an answer. In the meantime, I'm sorry for the delay. And your kitty is truly gorgeous!
That is not easy to see. but lets try to describe.
By the colors of the raised flag - my guess he is an Confederate American. He is a classical tabby (blotched, marbled, bulls eye). I think also he is a tortie. IF so, he is probably a she!
The breed look alikeness isnt easy to pinpoint. Technically a medium haired domestic, but probably one of them natural population, from whom the Maine Coon were once purebred from.
