How to Tell if Your Leopard Gecko is Dying

Determining if your leopard gecko is dying can be difficult, but there are some key signs to watch for. Leopard geckos are generally hardy pets, but they can develop health issues that can lead to death if left untreated. As a responsible pet owner, it is important to regularly monitor your leopard gecko and watch for any changes in behavior or physical appearance that could indicate illness or distress. Being aware how to tell if your leopard gecko is dying can help you get veterinary treatment as soon as possible and potentially save your pet’s life.

Signs of Illness

Signs of Illness
Signs of Illness

There are a few key symptoms that may indicate your leopard gecko is unwell and potentially dying:

  • Lethargy: Healthy leopard geckos are active and alert, especially at night when they are most active. A leopard gecko that is sleeping all the time or has trouble moving around the tank likely feels ill.
  • Loss of appetite: These lizards are voracious eaters, so loss of appetite or refusing food is a major red flag. Gecko’s metabolism depends on regular eating, so not eating can quickly lead to starvation.
  • Weight loss: Significant weight loss and a sunken abdomen or tail is a clear sign your gecko is not doing well and could indicate illness or parasites.
  • Labored breathing: Watch for open-mouth breathing, gasping, wheezing or other signs of respiratory distress. This can signal a lung infection or other health problem.
  • Discharge: Abnormal discharge from the eyes, nose or cloaca needs veterinary attention. It can indicate infection, impaction and other issues.
  • Inactivity: If your once active gecko hides all the time and shows no interest in anything, it likely feels sick.

Any of these symptoms means your gecko needs to see an exotic pet veterinarian right away for diagnosis and treatment. Catching problems early gives the best chance for recovery.

In addition to behavioral changes, look for these physical indicators of ill health:

  • Mucus in the mouth or nose – This can be a sign of respiratory infection.
  • Labored breathing or wheezing – This may indicate a lung problem or other breathing issues.
  • Swollen eyes – This can signal eye infection, vitamin A deficiency, or other health woes.
  • Tail kinking – A severely kinked tail can indicate metabolic bone disease from poor nutrition.
  • Abnormal skin or shedding – Ulcerations, reddened skin, bad sheds can mean illness.
  • Inability to stick to surfaces – Healthy geckos have sticky toe pads to grip surfaces. Loss of stickiness often accompanies illness.
  • Swollen joints or limbs – This may be a sign of gout, arthritis or bone disease.

Any physical abnormalities in your leopard gecko are cause for prompt veterinary care. Catching problems early is key to successful treatment.

Causes of Death

While signs of illness should be addressed immediately, here are some of the most common causes of death if left untreated:

  • Organ failure – Major organ dysfunction in the liver, kidneys, lungs or other organs ultimately leads to death.
  • Infection – Bacterial, parasitic and fungal infections such as crypto, parasites or mouth rot can kill geckos.
  • Respiratory illness – Pneumonia, lung infections and other breathing issues can prove fatal.
  • Dehydration – Insufficient hydration leads to organ failure.
  • Malnutrition – Starvation and deficiencies weaken the immune system and causes death.
  • Toxicity – Toxins, pesticides, or substrate eaten can poison geckos.
  • Old age Geckos can live 10-20 years with proper care. Death from natural aging is rare in captivity.

With attentive husbandry and veterinary care as needed, most causes of death can be prevented or successfully treated if caught early on. Act quickly if your leopard gecko exhibits any troubling symptoms or behaviors to avoid a tragic outcome.

Providing Proper Care

The best way to promote your leopard gecko’s health and longevity is by providing excellent care including:

  • Ideal enclosure – A proper sized tank with hiding places, heating, lighting, substrate, d├ęcor and humidity.
  • Healthy diet – Feed a variety of calcium-dusted insects along with occasional treats. Do not over or under feed.
  • Clean environment – Spot clean waste and change water daily. Disinfect and deep clean regularly.
  • Routine veterinary checkups – Have an exotic vet examine your gecko annually.
  • Observe behavior – Note any changes that could indicate illness like lethargy or appetite changes.
  • Quarantine new geckos – Isolate new arrivals for at least 30-45 days before introducing them.
  • Reduce stress – Limit handling to necessary maintenance. Provide a stable environment.
  • Supplements UVB – Dust food with calcium/D3 supplement. Offer UV lighting.

If you optimize husbandry and nutrition, many diseases and causes of death can be avoided. Be vigilant for any red flags or changes in your gecko’s condition. Seek prompt veterinary diagnosis and treatment if your pet seems ill. With attentive care and swift medical care when required, your leopard gecko can enjoy many healthy years with you. Act quickly at the first sign of trouble to avoid tragedy and untimely death of your pet.


Determining if a leopard gecko is dying and requires urgent veterinary care takes diligent observation of both behavior and physical symptoms. Key indicators include lethargy, appetite changes, weight loss, labored breathing, discharge, abnormal appearance, and inactivity. Underlying illness, infections, organ failure, toxicity and malnutrition are common causes of death if not treated early. As a responsible pet owner, provide your gecko with proper housing, nutrition, maintenance and annual vet visits. Act quickly and seek expert care at the first sign of distress to give your pet the best chance of recovery and a long, healthy life. With attentive husbandry and swift medical treatment as needed, untimely demise can often be avoided.
