The cost in shipping exotic animals overseas would be cost-prohibitive unless you're one of those rare individuals for which money is truly no object.

As a military spouse with reptiles, I'm prepared if we ever get stationed overseas, and that preparation does not (cannot) include taking my animals with me. It's just an unfortunate reality we have to deal with.

You may be able to find someone to keep them and take care of them for you until you get back...preferably someone you trust implicitly and that already has plenty of experience and space to keep your animals without it being a burden. Or you may have to sell them and then buy new when you get back.

Even if you stay stateside...if you ever get in a position that forces you to live on base/post...you may not be able to keep them there either. I'm not sure about the Army or other service branches, but all the Air Force bases now have a strict "no exotics" policy for base housing.
