Getting the import permit is a simple procedure, it takes a couple of hours max. All you need is the kitten's health certificate showing the updated vaccinations. When you're picking up your cat, don't worry, the guys at KLIA will usually ask you whether you want a person to help you with the paperwork, meaning be the runner for you so all you have to do is wait for the kitten You just have to pay him about RM100 and it's worth it as it's a pretty meticulous task and having someone do it for you is so much easier as there's a few places he will have to go to get the forms chopped, etc. Bringing cats in from Australia is the best as the kitten is not subjected to quarantine.
