In bringing a cat through customs, I understand it is necessary to have a letter from a USDA certified vet that the cat is in good health. Anything else?
Are you able to ship a bag of sealed cat food through a mundanza or bring it with you in a suitcase?
Tonchi, as I understand it, the USDA certificate is only necessary if the cat flies cargo. If you bring the cat on-board the aircraft with you in a carrier that will fit under the seat, you just need a good health letter from a vet. This was explained to me last spring when we brought my sister in laws cat back with us from Miami. We brought her aboard, just a vet letter, and a quick look and the payment upon arrival, no problem at all. We had no USDA letter/certificate.
The food is no problem either, sealed or not, just put it in your luggage inside another bag maybe, in case it bursts, and it will be fine.
I had envisioned all kinds of possible scenarios when we brought the kitty but it was very easy with no issues.
We flew into Santiago (STI)
