According to the American Miniature Horse Association, a miniature is based on height "Size: Must measure not more than 34 inches at the withers, at the last hairs of the mane." So, depending on how tall they are, they could be both Shetlands AND Miniatures, as some of Kay's horses are. In any case, they sure are cuddly looking, aren't they? :D
