The Somali cat is essentially the longhaired variant of the Abyssinian, one of the oldest recognized cat breeds. Longhaired kittens had been appearing in Abyssinian litters for decades before breeders began to take serious interest in them during the mid-twentieth century. The recessive gene responsible for the longer coat was likely introduced through outcrossing during the early twentieth century, when Abyssinian breeding stock was limited, particularly in Europe after the devastation of two world wars.
For many years, longhaired Abyssinian kittens were considered undesirable and were quietly placed as pets rather than being included in breeding programs. Breeders in both North America and Europe began to reconsider these cats independently during the 1960s and 1970s. American breeder Evelyn Mague is widely credited with championing the longhaired variety and giving it the name "Somali," a nod to the geographic neighbor of Abyssinia, present-day Ethiopia.
Mague founded the Somali Cat Club of America in 1972, and concerted breeding efforts quickly demonstrated that the longhaired trait bred true. By the late 1970s, the Cat Fanciers' Association granted the Somali provisional status, and full championship recognition followed in 1979. European registries recognized the breed around the same period, and Australian breeders also contributed significantly to establishing diverse bloodlines.
The development of the Somali as a distinct breed rather than a variant of the Abyssinian was a deliberate effort that required breeders to establish consistent type standards while preserving the ticked coat pattern, muscular build, and lively personality of the parent breed. Over time, the breed's unique flowing coat and dramatic ruff earned it the affectionate nickname "fox cat," a reference that has become one of its most recognizable associations worldwide.
