It might sound corny but my reason would be to propagate the species. I'm not speaking in regards to Ball Pythons only. I'd like to look back on my life knowing that I helped bring at least one new snake into this world ya know!
Plus I wouldn't want the snakes I have now pass away without leaving a part of themselves (offspring) behind.
Plus it would be thrilling to find out what the offspring will look like. Who knows? Let's find out!
Plus it would be nice to know that, for all the CH or WC snakes I may have or may end up with down the line, I helped produce snakes in captivity and contributed to the CB trade and the whole CB movement

.
Plus so I can make a lil money while providing enthusiasts and enthusiasts-in-training with quality animals.
As for my reasons, believe it or not, I actually feel that way.
