My 4-month-old gecko won't eat. How can I get him to start eating?

Updated on September 23rd, 2025

Pet's info: Reptile | Gecko | Male | unneutered | 2 months and 17 days old | 1lb

Hi, I have a 4 month old gecko and he isn’t eating. I’m worried about him. His owner had him on powder smoothie mix but I tried veggie and meal worms, he won’t eat any so I went back to smoothie and he is continuing not to eat

You can also try crickets or dubia roaches. Make sure any prey is appropriately sized, no bigger than the space between the eyes. At his age, you're going to be feeding pretty small prey.
Check the temps in the enclosure also. Low temps can affect appetite in reptiles. Soak him in a warm 50/50 solution of water and unflavored PediaLyte. This will provide warmth and may treat or prevent minor dehydration. You can also supplement with Fluker's Repta-Boost. Find it in the local Petco.

Make sure his enclosure is warm enough. Low temps can affect appetite and digestion in reptiles. A hot spot between 85 F and 90 F should warm the rest or the enclosure sufficiently. Provide at least two homes as well. One on the warm side and one on the cool side.
Offer appropriately sized prey, no bigger than the space between his eyes. Dust prey with an appropriate multivitamin and calcium supplement.
You can soak him in a warm 50/50 solution of water and unflavored PediaLyte. This will warm him up and can treat or prevent mild dehydration.
Of he doesn't begin eating in the next day or two, have him examined by your veterinarian or a vet experienced in treating reptiles.

My baby gecko won't eat. Why is this happening and what can I do?

Check the temperature in the enclosure. Low temps can affect appetite in reptiles. Also, be sure you are feeding appropriately sized prey. Typically, you want them no bigger than the space between the eyes. For a younger gecko of Ben's size, you may need to find 2-3 week old crickets.

Why won't my rescued leopard gecko eat after a diet change?

Give him a good soak (20-30 minutes) in a warm 50/50 solution of water and unflavored PediaLyte. This will provide hydration and warm him up which may stimulate his appetite. An exam with your veterinarian or an experienced herp vet is always recommended for "new" pets or pets that may be ill or injured. Offer food about an hour or 2 after the heat lamp comes on in the morning. This will allow him to warm up and he will be more likely to eat what is offered. Use a variety of prey if possible. This can include crickets, dubia roaches, phoenix worms and the occasional superworm. Superworms are good to feed if you have a skinny gecko that needs to put on weight.

My leopard gecko won't eat and is losing weight, what can I do?

Check the temperature in the enclosure. Low temps can affect appetite and digestion in reptiles. Soak her in a warm 50/50 solution of water and unflavored PediaLyte to provide warmth and hydration. Confirm appropriately sized prey, no bigger than the space between the eyes. You can offer crickets, dubia roaches, mealworms and phoenix worms. Gut load all prey for 24 hours prior to offering to maximize nutritional value. Submit a stool sample to your veterinarian to diagnose intestinal parasites. If she will allow, look in and around her mouth for any signs of injury or infection. This may include redness, swelling, discharge or bleeding. If you see anything suspicious, have her physically examined by your veterinarian or a vet experienced in treating reptiles to diagnose and treat any underlying causes.

My gecko stopped eating and is losing weight. How can I help him?

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.

Help! My baby bearded dragon won't eat. What should I do now?

Confirm proper temperatures. Low temps can affect activity, appetite and digestion in reptiles. Soak Jax in a warm 50/50 solution of water and unflavored PediaLyte. This will provide heat and may treat or prevent mild dehydration. Be sure prey is appropriately sized, no bigger than the space between the eyes. Look for pinhead crickets or freshly hatched/molted dubia roaches. Gutload them for 24 hours prior to offering to maximize nutritional value. Fluker's Repti-Boost can be used as a supplement. If Jax does not begin eating, have him examined by your veterinarian or an experienced herp vet to diagnose illness or injury.

My leopard gecko isn't eating and his tail is too skinny. What to do?

Make sure any prey is of appropriate size, no bigger than the space between the eyes. Confirm again that temps are within normal ranges. Low temps will affect appetite in reptiles. Soak him in a warm 50/50 solution of water and unflavored PediaLyte for 20 minutes daily. You can supplement with Fluker's Repta Boost. Find it in the local Petco. Look him over for any signs of injury or infection. This may include redness, swelling, discharge, bruising, bleeding or odd lumps/bumps. If he doesn't begin eating, you will need to have him physically examined by an experienced herp vet.

Why is my juvenile leopard gecko afraid of crickets and not eating?

Offer appropriately sized prey, no bigger than the space between the eyes. Confirm proper temperature as well. Low temps can affect appetite and digestion in reptiles. Be sure to dust prey at every feeding with a multivitamin and calcium supplements. Gutloading prey for 24 hours will also maximize nutritional value. Do not be concerned if she refuses food for one day.
