Road Trip

Yes, that's right, we are taking Macey on a road trip this summer.
She will get to spend the week as an indoor rabbit! She is very excited. Haha
What are some ways we can make her feel more comfortable while on the road?
My previous rabbit got bad diarreah (I'm awful at spelling) last road trip we took with her, and stunk up the car. Is there anything we can give Macey to prevent this from happening?

This recent thread has got advice about car travel:

Cant help with the diarrhoea, sorry. Am delighted to say that's not been a problem for Muppet! Why not take your rabbit for a short trip first, and see how she gets on?

Thank you
And will do~ Thank you.
