I thought with all of the dwarf boa posts in the last couple of days I would hime in. The larger boa on the outside is a normal sized 6 month old Colombian. The smaller snake on the inside is a Caulker Cay that is about 16 months old. They are both on the same feeding schedule, every 10 days, the Colombian getting slightly larger meals due to body size. This pic demonstrates how dwafed these boas really are.
