Domestic outcrosses from the early days in the 1990s have greatly impacted the breed's development in both desired and non-desired traits. As of 2012 most breeders perform Savannah-to-Savannah pairings; using outcrosses is considered less than desired. There are no longer any permitted domestic outcrosses for the Savannah breed now that TICA championship status has been achieved. Previously domestic outcrosses for the Savannah breed that were permissible in TICA were the Egyptian Mau, the Ocicat, the Oriental Shorthair, and the Domestic Shorthair.
