Can my hamster handle a long car trip? Safety tips for travel.

Many of our exotic companion mammals, such as hamsters, will do well in the car if their environment is kept stable. Since you are taking her in her cage, that may help. Other things that you will want to do is remove the water bottle while you are actively driving, but if you stop to take a break (ex: for gas, for you to eat something, or to use the bathroom), make sure that you put the water bottle in to give Mamy an opportunity to drink. Ensure that she has food available at all times as well. I would also recommend removing her wheel while you are actively driving so that she doesn't hurt herself on it.
One of the most important things for you to do in the car is to make sure it does not get too hot or too cold. I would recommend running the air conditioner in your car to get it to the temperature that your house would typically be, but make sure that the vents are not blowing directly on Mamy.
With Mamy being a hamster, hopefully she will sleep the majority of your time on your drive (unless you plan on driving at night). If you notice that she is restless or seems stressed, then I would recommend evaluating the temperature first. This is often the most stressful part of traveling for these little guys.
If you plan on staying in a hotel (which for that long of a drive it may be a good idea, just to give her a break), then you can have her cage set up as you normally would during that time.
I hope that helps, and that your trip is a success!
