I myself think, she has an ancestry of Bengal. A spotted bengal, giving her rest of rosettes, giving her also these rich warm colors.
And or a marbled bengal. So a guess is, some sloppy byb breeder mated his spotted bengal with a marbled bengal, because its what he had. Although the marbled one could of course be a nice classic tabby moggie.
And this is a grandchild of these two parents....
Technically, the cat counts of course as a domestic shorthair, classic tabby (called also for blotched or marbled).
