Scottish Fold History: Origin, Susie, and the Breed's Journey

Every Scottish Fold alive today descends from a single white barn cat named Susie, born in Perthshire, Scotland in 1961. This is the story of how a spontaneous mutation on a Tayside farm became one of the world's most recognizable cat breeds — and the difficult ethical decisions the breed has faced along the way.

1961: Susie

William and Mary Ross, a shepherding family in the village of Coupar Angus, noticed a white long-haired barn cat with unusually folded ears. Susie produced kittens the following year. Two of her kittens inherited the folded ears. The Rosses acquired one, a female named Snooks, and the breeding program began.

1966: registration in the UK

The breed was registered with the Governing Council of the Cat Fancy (GCCF) as the 'lop-eared cat.' Early outcrosses used British Shorthairs, giving the breed its now-signature rounded build and dense coat.

1971: journey to America

Geneticist Neil Todd imported three folded-ear cats to Massachusetts for study. When Todd's research concluded, the cats were placed with breeders including Salle Wolfe Peters, who began the U.S. Scottish Fold program that continues today.

1978: TICA acceptance

The International Cat Association granted championship recognition. CFA followed in 1978. The breed spread rapidly through the United States, becoming one of the top-ten most popular pedigreed cats within a decade.

The ethical reckoning

By the 1970s, veterinarians began documenting skeletal issues in cats from Fold × Fold pairings. Research by Malik and colleagues established the connection between the Fd gene and osteochondrodysplasia. The GCCF withdrew recognition of the breed in the UK in 1971 and has not re-registered it since. TICA and CFA retained recognition on the condition that all pairings be Fold × Straight.

Today

The Scottish Fold is registered by TICA, CFA, and most international registries under strict outcrossing rules. Ethical breeders worldwide, including Aurelian Folds, produce kittens only from Fold × Scottish Straight pairings. The breed's future depends on continued adherence to that standard.
