Scottish Fold is a breed.

@Lilac-JadeCanada if I was ever going to pay for an fancy-pants cat I would have a hard time choosing between a Russian Blue (IMO most beautiful) and a Scotch Scottish?)Fold ( makes me smile every time I see one).

@annewimsey500 The Scottish Fold is a distinctive breed of domestic cat characterised by a natural dominant gene mutation associated with osteochondrodysplasia. This genetic anomaly affects cartilage throughout the body, causing the ears to "fold", bending forward and down towards the front of the head. While this trait contributes to the breed's unique appearance, often described as "owl-like",[1] it also causes health problems.

The breed's name, originally lop-ears or lops after the lop-eared rabbit, became Scottish Fold in 1966.[1] Depending on registries, longhaired Scottish Folds are varyingly known as Highland Fold, Scottish Fold Longhair, Longhair Fold and Coupari.

Research has revealed that all Fold cats are affected by osteochondrodysplasia, a developmental abnormality that affects cartilage and bone development throughout the body. This condition causes the ear fold as well as malformed bone structures, and the breed can develop severe painful degenerative joint diseases at an early age.[2] Because of these health conditions, breeding Fold cats is prohibited in several countries, and some major cat registries do not recognise the breed.
