We brought our cats and we're glad we did. Import is easy...you just need to make sure you get shots up-to-date, etc.
This link (

Make sure you coordinate with your airline to make sure your cat can travel on the same flight as your family (in cargo unfortunately). It's easier if you can do it this way as you can then go to get the cat at the airport before heading on your way to your new home.
Also, you might consider looking into a pet travel agency that can help coordinate your travel. A quick Google search might find a few to talk to.
Import is relatively easy, but the vet at the arrival airport will want to check the cat out, check documents, etc. so that process will add about 2 hours at the airport after arrival.
