When reptiles gain or lose weight, they need to shed their skin to accommodate the change, like getting bigger or smaller clothes. Generally this is perfectly normal and no cause for concern. In fact, you probably won’t notice when your mourning geckos are about to shed unless you catch them in the act.
If your humidity is correct (between 60-80%), shedding should proceed smoothly. You won’t see a shed skin laying around — instead, it gets eaten by the gecko – a brilliant evolutionary technique for recouping nutrients which would otherwise be wasted.
