This is a subject I've really wanted to speak to lately.
First, let me say -- it's not "mailed". It is against the law to send snakes via the U.S. Postal Service.
You can ship Airport to Airport via Delta Airlines Delta "DASH" Service. You have to be known shipper. There are varying opinions on what that takes.
Secondly, most people ship with a Parcel Service -- UPS, FedEx, DHL. Requirements vary. I believe DHL does not allow shipping snakes.
My main focus here is in how the animals are packed.
I have gotten a lot of snakes shipped to me lately. Here are some things I've seen, that I ask people NOT do in the future.
1) When you ship with the molded Styrofoam "cooler" type liners, please put a few air holes in the container. Especially if you include a "heatpack". Heatpacks consume oxygen. They increase the snake's metabolism with the additional heat. When the type of liner is composed of individual pieces for each side, top, and bottom; air holes are probably not necessary.
2) Whenever you include a "heatpack" in the shipment please make sure there is a good physical barrier between the snake and the heatpack. Cardboard, or something like that. I got a boa in today, sitting on a heatpack that arrived with a body temperature of 91 deg.F. That's too hot. Unnecessary stress.
The same goes for "coolpacks", too. I've received boas sitting on top of coolpacks arriving at 52 deg.F. Just make sure to wrap that hot/cold thing up and attach it to the lid or side, as best you can. About half the time heat/cool packs shake loose in transit. Try to make sure there is a barrier.
3) Place a wad of paper towel or newspaper in the sack or deli cup for the animal's security. It gives them something to cling to. The paper towel or newspaper also acts to absorb any mess the animal may make in transit. It may also insulate the snake from a heatpack or coolpack, should one come into contact with the snake bag or deli cup while in transit.
4) Fill the additional space in the container with wadded up newspaper for stability and to cushion the animal in transit. Do NOT use foam peanuts or bubble wrap. They displace air/oxygen in the container. You want as much air inside the container as is possible, right? Besides that, no telling what kind of toxic fumes (formaldehyde) they may give off, especially if a "heatpack" is being used.
5) There is no need to completely seal the inner Styrofoam liner or outer cardboard box with sealing tape. I've seen people completely seal the lid on a "cooler type" inner Styrofoam container. Not necessary. Reduces air flow. Not good. Every seam on the outer carton does not need to be sealed, either. Let a little air in.
6) Pack them like it's going to take 48 hours for delivery.
Unfortunately, it does take that long or longer every now and then. Common sense goes a long way.
That is my rant.
