How do you help a leopard gecko from dying?

If your gecko is dying there are usually vital signs that will let you know. Sunken in eyes, almost looking like they're retreating back into the skull, is a sign that your gecko is dehydrated. If your leopard gecko has not eaten, or show any signs of passing fecal matter, this is a sign your animal could have impaction. If the animal has a wavy tail, these are preliminary signs of malnutrition which prominently lead to calcium deficiency. These are the common symptoms of a leopard gecko in distress.
