Hi, I'm new to this forum, and basically snake discussion. I plan on getting some ball pythons and boas in the future when I move out of my parents house (I'm in high school currently) and I've got quite a few years of snake handling experience under my belt, but none whatsoever with housing or keeping snakes. Back to the main point, I've never heard '1.1', '0.1', etc. when describing snakes, I've seen this in signatures and such. Any help please? Thanks!
