I’d say that’s a tabby. I just looked for pictures that didn’t have white + color, so the coloring would be more noticeable. The orange cat in my picture is also a tabby. Most of them are tabby anyway, since it refers to the pattern on the coat, and most cats have the same pattern regardless of color.
I think they are technically just huge long-haired tabbies since they are the result of colonizers’ cats adapting to the North American winters.
