Wolves, servals, jungle cats, geoffroys, caracals, and asian leopards are all excluded from the ‘positive list’ of animals that can be possessed in Belgium. Hybrids of exotic animals are not addressed at all.
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.
