Gecko shedding problems: stuck shed, toes, tails and how humidity helps

TUREFF• •0

Geckos shed their skin throughout their lives, more often while growing and less often as adults. A healthy shed comes off in a few pieces within a day or so, and many geckos eat the old skin, so you may not even see it. Problems begin when patches stay stuck, especially on the toes, the tail tip and around the eyes.

What a normal shed looks like

The gecko turns pale, dull or greyish a day or two beforehand.
It may hide more and eat less.
It rubs against décor and pulls the skin off with its mouth.
Afterwards the colours look bright and clean.

This is normal and needs no help. Avoid peeling skin off a gecko that is in the middle of shedding; let it finish.

Signs of a bad shed

Rings of old skin left on the toes or the tail tip.
Patches on the body that stay for more than a day or two after the rest has come off.
Skin around the eyes or eyelids that will not come away.
Repeated stuck sheds, shed after shed.

Stuck skin on toes is the most important to catch. Each layer tightens like a band, and over time it can cut off blood supply and the toe or tail tip can be lost.

Why sheds go wrong

Almost always the answer is the environment.

Humidity too low: the most common cause, especially in winter when central heating dries the air.
No humid hide for a leopard gecko.
Not enough rough surfaces to rub against.
Dehydration: a gecko that is not drinking enough sheds badly.
Health problems, such as poor nutrition or illness, which a vet needs to look at.

How humidity helps

The skin separates more easily when the gecko is well hydrated and the air around it is moist enough. Leopard geckos live in a dry enclosure, but they need a humid hide: a box with an entrance hole, lined with damp moss or paper towel, usually in the warm half. Re-dampen it every day or two and keep it clean so it does not grow mould. Most leopard gecko shedding problems are fixed simply by adding one. Crested geckos need regular misting, then time to dry out. A hygrometer, ideally digital, lets you see the actual humidity rather than guessing. Different care sheets give different targets, so follow one reputable source and aim for a daily cycle rather than permanently wet air, which encourages mould and skin infections.

Helping with a stuck shed

If skin is still stuck after the gecko has had its chance:

Make sure the humid hide or misting routine is right first.
Place the gecko in a small tub with a damp, warm (not hot) paper towel and a ventilated lid for a short time, supervised, so the skin softens.
Gently roll the loose skin off with a damp cotton bud. If it does not come away easily, stop.
Never pull hard, and never use tweezers near the eyes.

For skin around the eyes, persistent stuck skin, or any toe that looks swollen, dark or constricted, see a reptile vet. Removing it wrongly can damage the eye or the toe.

Preventing problems

Check toes and tail tips after every shed.
Keep a hygrometer and thermometers in the enclosure, and look at them.
Provide rough rocks, cork bark and branches to rub against.
Offer fresh water every day.
Keep the diet varied and supplemented, because poor nutrition shows up in the skin.
Note shed dates in a simple log. A change in frequency can be an early sign of a problem.

When it is more than a shed

See a vet if the gecko keeps having difficult sheds despite good humidity, if the skin looks red, swollen or infected, or if the gecko is also losing weight or refusing food. Repeated shedding trouble can be a symptom rather than the problem itself. Has your gecko had a stubborn shed? Tell us what helped, or ask a question, in the comments.
