The Oriental, Siamese & Related Breeds Group is a South African Breeders group started in the 1990's as a group of cat breeding enthusiasts, affiliated to the Governing Council of the Associated Cat Clubs of South Africa, which became The Southern Africa Cat Council (SACC).
The group staged Championship shows in 2000, 2007, 2008 and 2009.
It de-affiliated from SACC in 2010 and became a sub-club of the Cat Association of Southern Africa (CASA), a World Cat Federation (WCF) affiliate.
In 2012 the group de-affiliated from CASA as a sub-club and joined the leagues of the newly formed Independent Cat Clubs in South Africa.
