My 14-year-old gecko is skinny but still eating. What should I do?

Make sure any prey is appropriately sized, no bigger than the space between his eyes. They should be gut loaded for at least 24 hours prior to offering to maximize nutritional value. Consider adding LaFeber’s Emeraid for Carnivores, Oxbow’s Carnivore Critical Care or Fluker's Repti-Boost to get weight on him. Submit a stool sample to your herp veterinarian to diagnose intestinal parasites. If there are cryptosporidium in his stool, they may be responsible for his condition.

Pinky is severely emaciated and weak. She needs to see a reptile veterinarian immediately for any chance to save her. They may be able to help diagnose her underlying disease and offer supportive care or nutritional support. If her disease had progressed too far they can offer humane euthanasia to prevent her from suffering further.

Have him examined by your veterinarian or an experienced herp vet to diagnose and treat any infection related to the loss of the tail. In the meantime, increase tank temps by about 5-10 degrees F, soak daily in a warm 50/50 solution of water and unflavored PediaLyte for 20 minutes. Once he warms up and rehydrates, offer appropriately sized prey. Gutload prey for 24 hours prior to offering to maximize nutritional value. Supplement with a product such as Fluker's Repti-Boost to get weight back on him. You can clean the stump with diluted betadine or chlorhexidine. Use paper towels for substrate until the stump is healed.

Submit a stool sample to your veterinarian to diagnose intestinal parasites. Offer fresh crested gecko diet daily. Repashy or Pangea are brands I recommend. You can also offer appropriately sized prey (crickets, dubia roaches, mealworms, etc). Be sure to gut load them for 24 hours prior to offering to maximize nutritional value. Confirm proper environmental parameters. Low temps can affect appetite and digestion in reptiles.

Bump the temperature up to between 26 and 28 C. It's a small change, but 25C may be a bit to cool for Gargoyle geckos. Low temps can affect appetite and activity. The heat mat should be on one half of the tank. Lights can be turned off at night, but the heat source should stay on if nighttime temps drop. Makes sure the diet contains adequate amounts of vitamin D3. Without it, he is at risk of developing metabolic bone disease (MBD). A recommended diet is Repashy Crested Gecko diet. It is a powdered diet that can be reconstituted as needed. It can be found online or in most pet stores. The locusts fed should be gut loaded 24 hours prior to feeding. If he has a healthy appetite, submit a stool sample to your veterinarian or a vet experienced in treating reptiles to diagnose intestinal parasites. An exam with an​ experienced herp veterinarian would be strongly recommended to diagnose metabolic bone disease and to begin treatment. Supportive care may be indicated in light of the recent rapid weight loss.

The bump could be local infection or irritation. Monitor it for change or growth. Symptoms to look for are redness, increased swelling, bruising or sensitivity on that side. Make sure you don't have two males as this could lead to stress or bullying which can affect appetite. If you do have two males, provide a larger enclosure with multiple hides for them to use. Feed them separately if you can and use a kitchen scale to monitor the weight of the skinnier gecko. See your veterinarian or a vet experienced in treating reptiles if there is no weight gain or weight loss. Submit a stool sample to diagnose intestinal parasites.

Iggy does not look underweight but i have nothing to compare the way he looked before so i can't tell you for sure regarding weight loss. as long as he is active and eating normally i would not be worried, unless you see that he is losing a lot of weight fast.
