It is reported that it is illegal to breed from F1 and F2 females and it is illegal to breed Serval x domestic. A permit is required to own an F1 or F2 as a pet.
In order to import to Europe CITES import and export permits are required for F1 – F4 hybrids. From F5 on no CITES is needed, instead a TICA 5 generation pedigree to prove the cat is 5 generations removed from the wild cat. There are different regulations in each country for keeping hybrids.
