So the claim is that ball pythons have adapted in such a way that their protection against pathogens is related to humidity? Or do members now have access to some research that shows that ball pythons desiccate easily? More forum hokum and heresay? While I no longer keep ball pythons, I did and did so successfully - all at an ambient humidity of about 35%. Never an RI did we endure.

Now there are animals that have been documented to do very poorly at low humidity - balls just aren't one of them.

Ball pythons select micro climates in their zones that provide higher than ambient humidity during the day. Humidity numbers throughout their range are all over the board.

I agree with Alex - I'd be more concerned about reaching some artificial ambient humidity via misting, excess water and bad circulation. You feel the need to bump up humidity? Create and maintain a humid hide.
