With proper husbandry, leopard gecko shedding should never be a problem for your pet. The most important part of your husbandry will be a humid hide, as the moisture facilitates successful shedding of the whole skin.
Leopard geckos turn pale or a grayish color while in shed, but don’t be surprised if they return to their original color without leaving an old skin behind — leopard geckos, like most gecko species, eat their shed skin.
If your gecko is unable to shed their whole skin, circulation can be cut off in the toes and even the tail, and those parts will eventually fall off without intervention. Severe chronic shedding problems are known as dysecdysis.
If your leopard gecko is having trouble shedding, create a homemade humidity chamber. This can be constructed with a Tupperware and a warm, wet hand towel placed inside. If possible, place the Tupperware on top of a heating pad (regulated by a thermostat) set to 80 degrees. Once the chamber is warm enough, place the gecko inside, then cover the Tupperware with a cloth to make it dark — this will help reduce stress for the gecko. Keep the gecko in the chamber for no more than 20 minutes, then use a pair of fine tip tweezers to gently pry the stuck shed off. If it won’t come off, repeat the treatment the next day.
If the shed still refuses to come off after 1 week, make an appointment with your exotic veterinarian.
