Dysecdysis - incomplete or retained shed - is one of the most common welfare problems in captive reptiles. Understanding its causes and prevention is fundamental to reptile husbandry.
Dysecdysis causes significant welfare harm through vision impairment, pain from constricting retained shed on digits, and infection risk at retained shed sites. The condition is almost entirely preventable through correct environmental conditions - primarily appropriate humidity and the provision of humid hides. Owners who provide species-appropriate husbandry rarely encounter dysecdysis. The high prevalence of the condition in pet reptiles reflects both inadequate owner knowledge and the frequent sale of reptiles without appropriate husbandry information. Specialist exotic vet assistance is required for retained eye caps and constrictive digit shed that cannot be safely removed at home.
