So, I'm planning on shipping a nearly 3-year-old BRB.

I just bought a scale on Amazon to get an accurate weight measurement but I estimate her to be no heavier than 12 lbs. Maybe even 10. She's just a little over 5 feet long (boy are snakes hard to measure!)

What size box do you think is best? I'm thinking the 16x16x8 box from SYR's shipping kit no. 4 will be sufficient but I also don't want her to feel crammed in.

If anyone has shipped a larger snake like her before I'd be happy to hear how your experience went and what other special considerations you may have had.
