Hoping someone can give me some advice. I am moving overseas and will be taking a long car journey (6 hours) and an overnight ferry that will be 8 hours. I have two cats and very large carriers but I am worried about how they will be. I know you can rent a kennel on the ferry but I thought this would be more stressful for them, being around noise, dogs, people etc. But I know I can't visit them during the 8 hours and that also worries me. What can I do to make sure they will be ok. My boy particularly is very nervous cat.
