The cat must appear healthy.
Cats are subject to inspection at the port of entry. If a cat appears ill or shows signs of a disease that could affect people, a veterinary examination may be required at the owner’s expense.
Domestic cats entering the United States
CDC does not require proof of rabies vaccination for an ordinary domestic cat entering the United States, and USDA APHIS Veterinary Services has no general animal-health import requirements for domestic pet cats. Your cat must still appear healthy, and other rules may apply.

CDC and USDA do not impose a general microchip requirement for an ordinary domestic pet cat, but permanent identification helps connect the cat to its records and is especially valuable during international travel.
CDC does not require proof of rabies vaccination for cat importation, but CDC recommends vaccination. The destination state, territory, municipality or airline may also require it.
CDC and USDA do not publish a general minimum import age for ordinary domestic pet cats. A young kitten may still be unable to travel because the destination or airline requires a minimum age, rabies vaccination or health certificate.
The rules apply even when a cat arrives from the U.S. mainland. Do not use the continental-U.S. checklist as the final plan for either destination.

The short federal checklist does not override a state, territory, municipality, departure-country or airline requirement.
