Why Is My Chameleon Not Eating?

I am asked over and over “why is my chameleon not eating”. There are very few things more stressful than having your lovely, colorful little chameleon buddy eat like a champ for months on end and then suddenly lose their appetite. This is alarming behavior for novices and seasoned reptile owners. But don’t panic! Today we’re going to look at reasons that might be causing your chameleon to go off their food—it’s probably not as scary as you think! Let’s get started.

My Chameleon Is Not Eating – Understanding Typical Chameleon Feeding Behavior

First, let’s discuss typical feeding behavior. In the wild, chameleons are excellent hunters using their fabulous tongues to nab insects. They eat a wide range of bugs like crickets, locusts, and beetles. Some of the larger species may even try to hunt down small birds or other reptiles. Yum, right?

We try to mimic this diet as closely as possible in captivity. Crickets, roaches, mealworms, and superworms are chameleons’ favorite foods. You’ll need to “gut-load” these insects (feed them nutritious foods prior to giving them to your chameleon) and dust them with calcium and vitamins so your chameleon gets all the necessary nutrients they need to stay happy and healthy.

How Long Can Chameleons Go without Eating?

Alright, so your chameleon isn’t eating. How long can they safely go without food before they start to starve and run the risk of dying? The answer depends on the chameleon’s age, health, and species. Healthy adult chameleons can go one or two weeks without food without encountering serious problems, but it’s not ideal.

Juvenile chameleons need to be fed more frequently since they’re still growing and their body needs nutrients to help them develop into a healthy adult. If a young chameleon has gone more than a few days without eating, it’s time to do something about this behavior.

Why Is My Chameleon Not Eating? – Reasons for this Behavior

Let’s get into a bit more detail about some common reasons why your chameleon won’t eat.


Chameleons are very sensitive animals that become easily stressed by any change to their environment. New terrarium decorations, a change of light, or simply moving their enclosure to a new spot can make these animals feel uneasy. All these stressors may cause them not to feel hungry for a short period of time. To help reduce the amount of stress your chameleon experiences, it’s best to keep the environment as stable as possible and give them time to adjust to changes.


Illness is one of the primary reasons for a halt in chameleon feeding behavior. Respiratory infections are quite common if the humidity in their environment is too high. Symptoms include wheezing, difficulty in breathing, or mucus appearing around the nose and mouth. Another major cause of lack of appetite and poor health is Metabolic Bone Disease (MBD), usually due to lack of calcium or the wrong UVB lighting. If you suspect illness, you’ll need an experienced reptile vet to take a look at your scaly friend.


Dehydration can make your chameleon feel unwell and less likely to eat. Be sure to mist the enclosure daily and always leave fresh water out for them. Look for dehydration symptoms like sunken eyes or wrinkled skin. A well-watered chameleon is a happy, hungry chameleon!

Incorrect Temperature

Chameleons depend on their surroundings to regulate their body temperature. If the temperature within your chameleon’s enclosure is too low, there’s a good chance that the animal won’t be able to properly digest its food, resulting in a loss of appetite. Make sure to create a proper temperature gradient with a basking spot and cooler areas within the enclosure.


This behavior can be a bit confusing if you’ve never experienced it before. It’s similar to hibernation in mammals, but a little different for your reptile friend. During this time, the metabolism in your chameleon is low, and they tend to reduce activity and intake of food. This is normal behavior and seasonal. If you suspect that your chameleon is brumating, ensure they have access to fresh water and a comfortable living environment.

Fussy Eaters

Sometimes, chameleons can just be fussy eaters! They may get bored of eating the same food day in and day out. Try mixing it up with different kinds of insects. If you change things up and don’t notice your chameleon snapping up their food, one of the above reasons might be the cause of their loss of appetite, and it’s time to take them to the vet.

Knowing When to Go to the Vet

Knowing When to Go to the Vet If you chameleon isn’t eating, and you’ve ruled out the environmental and behavioral variables mentioned above, it’s time to seek help for the colorful critter. You need to take your pet to the vet, preferably one who has experience in handling chameleons and other reptiles. Here are some of the signs it’s time for a professional check-up.

Severe Anorexia – Your chameleon hasn’t eaten in more than one week and is showing no interest in any food.

Lethargy – Your chameleon is quiet and seems unusually inactive or weak.

Unusual Colors – Your chameleon has a dull color or presents unusual colors for a longer period than normal.

Breathing Problems – You notice wheezing, heavy breathing, or mucus around their nose and mouth.

Swollen Limbs – This can be a sign of the life-threatening condition “metabolic bone disease,” and requires immediate treatment.

Tips to Encourage Your Chameleon to Eat

Sometimes a bit of encouragement is all it takes for your chameleon to get their appetite back on track. Here’s how to stimulate their appetite.

Variety – Provide variety in the insects you offer your scaly friend. Try crickets, roaches, mealworms, and silkworms to pique their curiosity and appetite.

Gut-Loading – Ensure the insects have good nutrition from food in their system before you give them to your chameleon.

Dusting – Ensure you dust the insects with calcium and vitamin supplements for your chameleon to receive all the micronutrients they need from their diet.

Force-Feeding/Hand-Feeding – Some reptiles can be enticed back to eating by force feeding or hand-feeding. Feed them gently using tweezers to grip the food source.

Recheck Climate – Be certain that temperature, humidity, and UVB lighting in the enclosure are all optimal.

How Long Can Chameleons Go Without Eating?

How long can these colorful reptiles go without eating? There’s nothing wrong if your chameleon occasionally skips a meal. Normally, an adult chameleon can go a week or two without any serious problems resulting from not feeding, but this doesn’t mean you should let them starve away. If the chameleon goes more than a few days without eating, something might be wrong with them.

Baby chameleons need to eat more because of their growth needs. If a baby or juvenile chameleon goes off its food for more than a couple of days, it’s critical to resolve the issue fast. Their smaller size and faster metabolism mean they can dehydrate and become malnourished much faster than adults.

Final Thoughts

It can be very worrying to discover that your chameleon stopped eating, but most times, with a little detective work and care, you can get to the bottom of this issue and resolve it. Remember to check their environment, keep an eye out for signs of illness, and contact a vet if the situation calls for it. A varied diet, hydration, and the right conditions are important for the well-being of your chameleon, so ensure you have proper husbandry skills to take care of your scaly friend.
