Gecko species kept as pets have specific humidity requirements that vary dramatically between species, and incorrect humidity management causes chronic respiratory disease and dysecdysis.
Gecko welfare failures from incorrect humidity management are among the most common reptile welfare problems seen by exotic animal veterinarians. The consequences - retained shed skin causing toe necrosis, respiratory infections, and corneal damage from retained eye caps - are painful and progressive. The solution is straightforward: research species-specific requirements before purchase and invest in the correct equipment including hygrometers and appropriate misting systems. The welfare failure occurs most often when owners acquire geckos without understanding species differences.
