Hamster transport will be needed if you have a vet appointment, a child's show and tell, or are moving to a neighboring city. There are a few things to remember while transporting a hamster that will make the ride safer and easier for you and your pet.
Containers
Pick a type of container that your hamster won't readily chew through. A cardboard shoebox is commonly used, but by the time you and your hamster reach your destination, there are typically empty boxes or large holes from chewing that you hamster can easily escape from. There are great travel sized carriers for hamsters available, or you can make your own with a small plastic container with a lid and holes poked in it. Old margarine tubs, coffee containers, and inexpensive plastic storage containers can all easily be converted into a hamster transport device, and you can even let your child customize it with stickers and craft supplies. Just be sure to poke small holes in it first!
Ventilation
Don't underestimate the squeeze power of a hamster. They can fit through some tiny spaces, so if their head can go through it, they'll probably find a way to squeeze their body through as well. This having been said, don't put your hamster in a box that has big holes in it. Try to keep the holes the size of a pencil-top eraser. Also be sure there are several of these small holes around the transport container so your hamster can breathe easy on their trip.
Temperature
Don't leave your hamster unattended in the car on a very hot or cold day. Also heat up a cold car that has been sitting outside on a cold day, and turn the air-conditioning on in a hot car on a hot day. Try to avoid drastic temperature changes.
Bedding
Provide a comfy ride for your hamster. Shredded paper towels, recycled paper bedding like Carefresh, or another soft substrate will be the best choice for a car ride. This will absorb any wastes created on the ride, as well as allow your pet to burrow and hide on the journey.
Chew Toys
Provide a small amount of food, a treat to munch, or a chew toy in case your hamster wants to nibble on something during the ride. This will also deter him from chewing on the transport cage.
