Are shot records needed to bring my cat into ZIH via flight?

Mexico does require rabies vaccinations for cats, unlike the US.

The big thing is what the airline requires. Mexico doesn't require much, but airlines all have their own requirements that you must meet or you won't fly with your cat.

The information should be on each airlines website, and don't forget to make your pet's reservation too. Airlines limit the number of pets in the cabin per flight.
