Will a hamster die if it travels a lot

If your hamster is traveling as cargo, find out what the other cargo is (in case it's harmful) and be sure to properly label your hamster's crate.

Don't feed your hamster airline peanuts :)

Food

Have a supply of complete food that your hamst is familiar with so you rhamster doesn't have to adjust to a different kind of food in a strange place. This can also prevent indeigestion, stress, illness, and hunger.

Lighting/Climate

Maintain (as much as possible) a steady 12-hour light/darkness routine (traveling or no). Keep the temperatur a comfortable room temperature for humans, maybe slightly cooler. Besdies, hamsters have a thick fur coat and cannot sweat (to the best of my knowledge) except out of their paws like dogs. Also keep carrier out of direct sinlight and drafts.

Illness

Cause: The cause can simply be from stress (unusual smells, drafts, food, water, bedding, lighting, people, etc). It can also be caused by poor bedding, water or food.

Here are some pointers on bedding, water, and food WHILE TRAVELING.

Bedding & Cleaning: Use the same bedding your hamster is used to, and mix it in with about a handful of un-soiled bedding from the previous cage-cleaning. This way, the scent of your hmaster smells from the leftover bedding will be comforting and give it a snse of being at home. If you are traveling with your hamster for more than a week, then a cage-cleaning isnecissary. Put your hamster in a stress-free holding cage while cleaning its home. Use the same bedding arrangements as above. If that is not possible, just us un-inky newspapers to cover the bottom of its cage.
