LOL vetusvates, that sounds like a nice neighbor.
I was confused, at first I thought that the snakes where being shipped in a pillow case... lol. Nothing wrong with shipping snakes.
I once tried using USPS to ship my snake to my new house in RI, but the lady was adamant about not letting it happen.
The story is kinda funny, actually. I went down there with my fish, snakes, and cockroaches all packed up and ready to go. I told the lady what was in the boxes, and she gave me a look of horror. Everyone else in the office looked at the roach box with suspicious/fear. XD
She said that I could ship the fish, but not the roaches or snake. Which was odd, because the roaches weren't considered a pest species and the snake was a US native (corn snake).
