I have US citizenship, my wife is a Mexican citizen working on her visa. She has a cat she can't live without and I am trying to figure out how to get it up here. Do I just talk to the airport and pay a fee?
According to the CDC, import requirements for pet cats are pretty relaxed. However, additional requirements may apply based on the destination state, county, or city.
For information about flying with a cat, contact your airline. They will probably have different rules depending on whether the cat is accompanied (considered personal baggage) or not (considered cargo). I flew my cat domestically (within New Zealand) on a 1.5 hour flight unaccompanied, so I had to pick him up at the cargo depot at the destination, rather than regular passenger baggage claim. There will probably be more paperwork required for international pet transport.
