The Savannah cat is the largest of the cat breeds. A Savannah cat is a cross between a domestic cat and a serval, a medium-sized, large-eared wild African cat. The unusual cross became popular among breeders at the end of the 1990s, and in 2001 The International Cat Association (TICA) accepted it as a new registered breed.
Judee Frank crossbred a male serval, belonging to Suzi Woods, with a Siamese to produce the first Savannah cat on April 7, 1986. In 1996, Patrick Kelley and Joyce Sroufe wrote the original version of the Savannah breed standard and presented it to the board of The International Cat Association. In 2001, the board accepted the breed for registration. The Savannah cat can come in different colors and patterns, however, The International Cat Association (TICA) breed standards only accept spotted patterns with certain colors and color combinations.
