The story of the Scottish Fold begins in 1961 on a farm near Coupar Angus in the Tayside region of Scotland. A local shepherd named William Ross noticed a white barn cat with unusual folded ears living among the farm cats belonging to his neighbors, the McRaes. The cat, named Susie, had a distinctive owl-like appearance created by her forward-folding ear cartilage, a trait that had never been selectively bred for and appeared to be a spontaneous natural mutation.
William Ross and his wife Mary were so taken with Susie's unique look that when she produced kittens in 1963, they acquired one of the folded-ear females and named her Snooks. Working with a local geneticist named Pat Turner, the Rosses began a careful breeding program to understand and perpetuate the folded-ear trait. Early crosses with British Shorthairs and domestic cats revealed that the fold was caused by a dominant gene, meaning only one parent needed to carry it for the trait to appear in offspring.
The initial breeding program produced 76 kittens over the first three years, with 42 displaying folded ears and 34 having straight ears. This roughly equal split confirmed the dominant inheritance pattern and gave breeders their first reliable data on the genetics behind the fold. These early kittens became the foundation stock for the entire breed, and virtually every Scottish Fold alive today can trace its lineage back to Susie and those first litters on the McRae farm.
The name "Scottish Fold" was formalized during the late 1960s as breeders sought recognition from cat registries. The breed was initially called "Lops" after lop-eared rabbits, but enthusiasts felt the name failed to honor the breed's Scottish heritage. The adoption of "Scottish Fold" tied the breed permanently to its geographic and cultural origins, giving it an identity that resonated with cat fanciers around the world.
