Just wanted to pop in and say shipping live mamals might be illegal and when its not it takes VERY special considerations and permits to do so which is not cost effective. You may already know this but the wording of your topic sounds like you are looking to buy online and have shipped.

I was just reading a topic on Fauna the other day which involved someone shipping rodents which turned into a disaster...some or all where dead and sending party KNEW it was illegal to ship them.
