I'd like to know about popping too.

How easy is it to learn to pop snakes to determine their sex? Is it possible to learn from reading online and looking at pics? Or is it really not a good idea to try without someone who knows what they are doing instructing in person?

I'd appreciate any advise or links anyone can post, especially pics! How do you do it? What do you look for to determine the sex? How big is to big for popping?

I'm primarily interested in ball pythons, but I guess it would be a lot the same for other species of snake as well?

Thanks!
