See Servals in Person
Are native to Africa and the only place to see them in the wild.
There are also many zoos and other such places that keep servals. In southern California, in the United States, I know of three such places.
The San Diego zoo has a good reputation for animal care and has servals on display.
Another place is Shambala, a refuge for wild cats with no home.
The place I most recently learned of is he Exotic Feline Breeding Compound’s Feline Conservation Center, nicknamed ‘The Cat House'’
Here are links for more information about each location.
