Food & NutritionMy lizard is shaking and won't eat. What should I do to help?
Check the temperature in his enclosure. Low temps can affect appetite in reptiles. If he isn't eating or not exposed to high quality UVB lighting, he can become calcium deficient which could account for the tremors.
If he is less than 30 inches long, confirm a basking temp of around 115 F. If he is bigger, bump basking temp to between 125 F and 135 F. Multiple lower wattage lights over a larger area are recommended over one high intensity light source.
Try to get him to eat and offer a calcium supplement. If you can get a liquid supplement, that would be best right now. Zoo Med and Fluker's offer such a supplement.Soak him in a warm 50/50 solution of water and unflavored PediaLyte to treat or prevent minor dehydration.
if he doesn't eat or if the tremors worsen, have him examined by your veterinarian or a vet experienced in treating reptiles as soon as possible.
