Mmmm, that IS quite an epic journey by public transport. Stressful for you and the fur-babies. I think I would be inclined to find a compassionate friend. The good thing about that is that your friend is bound to fall in love with ratties while looking after them, and ratty world domination is a step nearer! My OH wouldn't let me have rats until I looked after a friend's girls on the strict understanding that she would have NOTHING to do with them. It only took a couple of days before she was enchanted and we have had rats of our own ever since!! I am sure you will be able to find someone to look after them nearly as well as you!! Good luck - and let us all know how you go!
