3 hour ride (pick up)

okay so hopefully with in the next week i will be abil to pick up my new baby, it will be a 3-4 hour one way drive, so i was wwondering what i can do to make the hedgie feel more comfortable on the way home? i have a hard sided cat carrier, but is there anying else i can give her or put in with her to help? i didint have to worry about this when i got daisy sence it was only a 20 min drive. :lol: anyway u just want to make sure i do whatever i can to make her more relaxed Thanks,
