You could contact KitKats pet transport. They do a cat only run.
Your cat will have to be chipped, passported and rabies innoculated. After this has happened, the kitten will have to wait 21 clear days (22 in total) before travelling.
I am not certain about the legislation surrounding the age of innoculating and travel as I believe that puppies now have to be at least 4 months old unless travelling with mother. But they will be able to tell you at what age the kitten can travel.
