If a cat has clear features of another established breed, such as an extreme flat face, what is its likely ancestry?

Answer

It is more likely to be a deliberate mix or a blend of native stock and later introduced domestic lines

If a cat exhibits clear features of another established breed, like an extremely flat face, it suggests the ancestry is a blend involving later introduced domestic lines, rather than the classic, pure, naturally developed Maine Coon.
