Regarding this, you might want to read over this section of the Ship Your Reptiles web-site, even if you're not using them to ship your animal (http://www.shipyourreptiles.com/en/get_help). There are various Federal laws and regulations you need to make sure you're in compliance with before you ship your animal. Not trying to talk down to you or sound like your parent but your actions can effect everyone in this hobby/industry so please make sure you're in compliance with the law while you're shipping. Ignorance of the law isn't a defensible explanation if you're charged and/or fined for improper shipping of an animal; not saying that from me personally, just stating what would be relayed to you if it arises to the level of the U.S. Fish and Wildlife Service becoming involved. The "Shipping Standards" section can also answer some of your questions regarding how to pack your snake for a safe arrival. Take care and hope that helps!
