Additionally, to purchase endangered felines in interstate commerce, USDI requires that the buyer register with the U.S. Fish and Wildlife Service for a permit before any commercial activity is conducted. Exotics have small litters, unlike domestic cats. Raising these felines is more for the love than the money and you should not expect to get rich breeding exotic cats. No matter the size, whether indoors or out, a cat requires its own space and a place in which it can be safely kept when not monitored by you. For small indoor cats, a safe room and crate will work, though this will generally not meet state or federal permit requirements.
Hybrids are cats that result from a cross of two species.
Geoffroy cats, Leopard Cats, Servals and African Jungle Cats have recently been successfully crossed with domestic cats. These hybrids are called Safaris, Bengals, Savannahs and Chaus hybrids, respectively. The male first generation animals are sterile, although the females are fertile if bred back to a domestic cat. Hybrids do not fall under any of the endangered species laws, however most city laws do include hybrid wild animals in their interpretations. Breeders of hybrids may fall under USDA permitting requirements which cover all warm blooded animals.
