Scottish Fold
Feline Federation Europe (FFE) calls them (in the same breed standard), the British Longhair Variant, the Highlander, and the Highland Straight. However, the latter two of those names have already been used by other registries to refer to completely different cats. The Highlander (with a variant, the Highlander Shorthair) is actually a development from the American Curl, and not closely related to the British breeds; it is a very large cat, with close-set, often upward-curling ears. The Highland Straight, a British breed, is actually the straight-eared variant of the Highland Fold; together, they are the longer-haired versions of the Scottish Straight and Scottish Fold, respectively. (TICA uses different terminology: Scottish Fold, Scottish Fold Longhair, Scottish Straight and Scottish Straight Longhair, to avoid confusion with the Highlander.)
