Incorrect humidity is a major cause of health problems in captive reptiles. Understanding species-specific humidity requirements prevents dysecdysis, respiratory infections, and dehydration.
Humidity mismanagement causes preventable suffering that reflects inadequate pre-purchase research by keepers. Retained sheds constrict toes and fingers progressively, with the constriction causing ischemic pain and eventual necrosis. Eye cap retention impairs vision and causes discomfort with every blink. Respiratory infections from incorrect humidity cause labored breathing that distresses reptiles and can progress to fatal pneumonia. The diversity of reptile species in the pet trade — each with distinct environmental requirements — makes species-specific research not a responsibility that can be deferred. The welfare of a reptile is determined at the point of purchase, when the keeper commits to understanding and meeting species-specific needs.
