Oh, not to derail the thread but didn't Dr. Steve Gorzula's expedition find ball pythons cohabitating in the same borrows? Its been some time since I've watched the DVD but I have it around here somewhere.
Not saying what happens in the wild should necessarily happen in captivity. Isn't there also a discrepancy between life-expectancy wild versus captive born & kept? I am under the impression that captive bred & kept BPs can live three times typical wild life-expectancies [20-40 versus ~8-12 years].
