Bandit should do just fine, does he "pal" around with the other 2 when at home? i have traveled with 2 different cats, the first started his travels at the ripe age of 10. I tried the carrier thing, but he figured out how to bust out!!! Now I travel with cat #2, he started traveling as a kitten right from the get go. He is a good travler, but like others have already said - Be sure you secure your cats before moving the slides!!!!!!!!!!!!
Good luck with Bandit, hope he lives a long life and he is lucky to have such great owners who will take care of him.
