The majority of states follow the code set by the Department of Agriculture which defines wild/domesticated hybrid crosses as domesticated. Some states have set more restrictive laws on hybrid cat ownership, including, but not limited to: Hawaii, Massachusetts, and Georgia. Some cities may invoke laws that differ from the state. For example, Savannahs more than five generations from the Serval are allowed to be owned in New York state, but not in the city of New York.
The Australian Federal government has banned the importation into Australia of the Savannah cat, as the larger cats could potentially threaten species of the country's native wildlife not threatened by smaller domestic cats. A government report into the proposed importation of the cats has warned the hybrid breed may introduce enhanced hunting skills and increased body size into feral cat populations, putting native species at risk. The report states that the Savannah cats are not worth the risk.
