Thank you for replying, I'm getting myself into a proper tizz over this...I do have a cage over there and she has a carrier, but my problem is what mode of transport to use.
I can't fly with her, even if they took pets, they'd make her go in the hold & I won't put her through that so I looked at getting a coach but the National Express coaches go via Southern Ireland so I'm not sure about crossing the border with her.
I could go via ferry maybe, there are ferries from Birkenhead, Fleetwood and Stranraer but again, I'm not sure if they'd tell me I can't carry her.
However, I am certain there must be some way of doing this.

I have emailed the companies I may buy tickets from but I was wondering if anyone has any experience of travelling with rats, just for tips etc...my next question will be keeping them happy over such a long journey. It concerns me that she'll be stressed out even with me there talking to her. I am considering leaving her with a sitter but if I'm honest, I don't trust my friends to play with her as much as they should, or clean her out properly...I know they'd probably be fine but I'm a worrywort!
