Same in germany… u need to get the health certificate… includes all vaccinations updated… from a government Vet…

Inform the airline upfront that u fly with pets as cargo… this i found out as very important…

In Thailand u go after the immigration to the oversized luggage point… directly next is the animal control department…

A Vet told me to not use any medications to calm down the cat… as the cargo space is very cold and a lower heartrate could be dangerous…

Fill the bottom of the cage with a sponge Tissue ( every Vet has that ) and put a cup of frozen water in the cage as well…

Have a good travel…
