Velcro goes with me whenever I travel, and I use an ordinary hamster cage! At first I covered the cage with a towel because she was anxious, but now she sits on the dashboard and basks as we travel...Our longest trip was from Johannesburg to Port Elizabeth, and she was fine! If she became restless, I just put her back into her cage and covered it for awhile.
We spend a lot of time handling her while she is travelling, and she loves it! I just make sure that she goes for a "poop-walk" on the lawn before we travel - it works just as well as a swim.
While we are away from home I make sure that she gets a few hours of direct sunlight each day - she is now so spoilt that she sulks when she is in here vivarium at home! I actually put her out into the natural sunlight every day - not sure if she will enjoy that as much in winter, but will adjust accordingly! I cannot bear to keep her in an unnatural environment when we have such a perfect natural environment in our country! Velcro agrees...good SA sunlight rocks!!!
I never leave her at home ... she's family!!!
