4 phone calls, 3 departments and a very hard to understand voicemessage I have found the Importation of Pets and Other Animals into the United States page (this page also has information on birds, dogs,monkeys and turtles) which states “Pet cats are subject to inspection at ports of entry for evidence of infectious diseases that can be transmitted to humans (zoonotics). If a cat appears to be ill, further examination by a licensed veterinarian might be required. There is no rabies vaccination requirement for cats. Following entry into the United States, all cats are subject to state and local vaccination requirements. Looks like we don’t need any further documentation as far as the states are concerned. The airline needs some paperwork too though…..
That zoonotics makes a nice word-of-the-day.
