Immigrate cats to America.

The cats carried by passengers are inspected at the port of entry. If port officials find that they have signs of diseases that may spread to humans, cats will be banned from entering the country. If the cat shows symptoms of illness, officials at the port of entry will ask the owner to ask a registered veterinarian for further examination at his own expense.

Similarly, the US Centers for Disease Control and Prevention does not require cats to be vaccinated against rabies when entering the country. However, some states require cats to be vaccinated against rabies when they enter the country. Therefore, travelers should contact the destination state and local health authorities for confirmation in advance.

Hawaii and Guam stipulate that all pet cats arriving there, even those from the United States, are subject to compulsory quarantine.
