Why Wont My Iguana Eat

Common reasons why iguanas stop eating

It’s common for iguanas to lose their appetite. Various factors could cause iguanas to stop eating, which could be detrimental to their overall health and well-being.

These factors could include:

  • Stress from a new environment or owner
  • Inadequate lighting and temperature conditions
  • Diseases or infections

Without proper attention and care, these factors could lead to severe health complications for an iguana and may have long-term consequences.

Ignoring such warning signs and not addressing the reasons why the iguana isn’t eating will only make things worse. Ensuring the iguana has a diverse, balanced diet that includes leafy greens is crucial for maintaining their overall health.

Pro Tip: It’s important to consult a professional veterinarian who specializes in reptile care as soon as you notice a loss of appetite in your iguana. Early intervention can save your pet’s life. Looks like your iguana’s snooty taste in foliage is getting in the way of a balanced diet – time for some tough love and a trip to the pet store!

Environmental factors

Iguanas’ eating habits and wellbeing can be hugely affected by their living conditions. Temperature, humidity, and access to water all influence their wellbeing. Iguanas need certain environmental conditions to stay healthy and feed properly. Poor care can lead to them not wanting to eat and bad nutrition.

Household products, cleaning agents, and pesticides can also have a negative impact on their appetite. These substances can cause digestive problems and make it harder for them to eat. Plus, keeping them in too small or overcrowded spaces can affect their routine.

Bad hygiene in their environment can cause health issues over time. This includes mites, bacterial and fungal infections.

For example, a family kept their iguana in a badly-ventilated room with low lighting and noise; this made the reptile anxious and stop eating.

Owners must make sure their iguanas have proper living conditions with the right temperature, light, and moisture. This helps digestion and avoids dangers that could ruin their feeding habits. A sweater could also help combat the cold and avoid reptile dysfunction!


Maintaining optimal temperatures is essential for a pet iguana’s good health. Issues with heating and cooling can lead to loss of appetite – and even death. Here’s a breakdown of temperature-related problems that can stop your iguana from eating.

Inappropriate Temperature (Low or High)LethargyUse a thermometer. Check & adjust temperature settings. Provide basking spots & UVB lighting.
HumidityShedding issues, upper respiratory infectionsAim for humidity level between 60-70%, indoors & out.
LightingDull scales, MBDMake sure your iguana gets enough UVB lighting, indoors & during outdoor basking.

In addition to regulating temperatures, provide fresh water, nutrient-rich foods, and keep the living area clean to prevent digestion problems.

To help your iguana eat again, check its temperature, lighting, and humidity with thermometers and hygrometers. You can also consult an exotic vet for advice on creating a healthy environment. Don’t let bad lighting be the reason for your iguana’s lack of appetite – it’s no excuse!

Lighting is important for iguanas. Wrong lighting can cause health issues and a lack of appetite. Different lights have different functions, as shown in the table below.

Light TypeFunction
UVBProduces Vitamin D3 to help process calcium.
UVASustains body functions and mood.
Basking LightMaintains temp, simulates sunlight, enhances feeding.

Get the right wattage, lifespan, and color spectrum bulbs. Change UVB bulbs every 6 months.

Your iguana needs food, water, heat gradients, moisture, and light. Create a schedule for replacing lamps to avoid any behavioral changes.

Pro Tip: Take care of your iguana like you would an ex-roommate!


Maintaining proper living conditions for iguanas is essential for their well-being. Poor habitat can lead to behavioural changes and stop eating.

Temperature control is an important factor in creating a suitable habitat. They need both hot and cool areas. Plus, they need adequate lighting, humidity levels and space to move.

For mental stimulation and physical activity, adding accessories such as perches, hiding spots and climbing structures mimicking their natural environment is also important. This will help regulate their appetite.

Providing a suitable diet for iguanas and watching out for signs of illness or stress can prevent further issues due to bad living conditions.

Take the necessary steps to maintain their environment to ensure your iguana is happy and healthy in their new home.

Health concerns

Iguanas may lack appetite due to underlying health concerns. These vary depending on breed, climate and habitat. Parasites, infections or insufficient UV light exposure could be to blame. Kidney disease is one of the main causes of mortality in pet iguanas. It can cause weight loss, loose stools, reduced urination and gout. A vet should be consulted to diagnose and prevent potential fatalities.

Stress from environment changes or incorrect diets can also lead to anorexia. Low calcium levels can impair muscle function, and excess protein could be toxic over time. Owners should monitor their pets’ eating habits and look out for adverse symptoms.

According to The Merck Veterinary Manual, growth rates differ between sexes. Females typically reach a max size of 2 meters, whereas males only average 1.5 meters. So, don’t blame the iguana for skipping meals – those pesky parasites might be stealing all the food!


Iguanas can cease appetite due to various causes, for example, internal and external parasites. Parasites are living things that take nutrients from their host. When parasites affect iguanas, they may suffer digestive issues leading to no appetite. Common parasites affecting iguanas are mites, ticks, tapeworms, roundworms, and flukes.

Parasites can be simply transmitted between iguanas by contact with unclean surfaces or infected animals. Iguanas in unhygienic environments or with bad hygiene practices are more prone to parasitic infections.

It is crucial to get a qualified diagnosis from a vet if an iguana presents signs of parasitic infection. Treatment usually includes medication and regular check-ups to make sure the parasite has been fully eliminated.

Pro Tip: Cleaning the iguana’s enclosure and proper hygiene practices can help stop parasitic infections in iguanas.

Refusing food due to infections is like a veggie refusing a salad – abnormal behavior.


Infections can be a real issue for iguanas. Bacterial infections, like salmonella, can stop them from eating due to their digestive system being affected. Fungal infections, like Aspergillosis, can also cause respiratory problems and too much mucus, making it hard for them to eat. Parasitic infections, like Coccidia and Cryptosporidium, can cause diarrhea and dehydration.

It’s important that an infected iguana is not handled by humans. Seeking help from a vet is essential. Recently, a friend of mine noticed her iguana had stopped eating and had unusual bowel movements. After taking the iguana to the vet, they diagnosed him with a parasitic infection and provided treatment. The iguana made a full recovery, but it’s essential to be aware of potential risks before handling an infected reptile.

Counting calories is not necessary because metabolic disorders can cause iguanas to lose their appetite quickly.

Metabolic disorders

Metabolic imbalances can cause normal iguana functions to go haywire. Vitamin deficiencies, low calcium levels, and poor hydration are the likely culprits. If not dealt with, the iguana’s appetite will decrease. Symptoms of metabolic disorders: weight loss, muscle tremors, and lethargy.

Accurately diagnosing the problem is essential. Wrong diagnosis can be deadly! Calcium, vitamin D3, and electrolytes must be given based on a vet’s advice. In severe cases, IV fluid therapy may be needed.

Preventive steps include good lighting and heat, hygiene, and a balanced diet. Studies show metabolic bone disease is common in captive iguanas due to inadequate amounts of vitamin D3 and calcium (Journal of Zoology). Don’t ignore bad behavior! Food is life.

Behavioral issues

Iguanas are complex creatures and their feeding behavior can be affected by many factors. Environmental stressors, such as changes in temperature, humidity or lighting, can lead to a decrease or increase in food intake or even fasting. Poor handling techniques used by pet owners can also cause issues.

Other reasons iguanas might stop eating include underlying health problems, such as parasites, infections or diseases like metabolic bone disease and respiratory infections. Also, dietary deficiencies or imbalanced diets lacking vitamins and minerals may result in malnutrition.

It is important for owners to monitor their iguana’s feeding pattern. If any changes or environmental irregularities occur, action should be taken and a vet consulted if necessary. Prolonged starvation can cause serious health problems such as renal failure or liver disease, so appropriate care must be provided at all times.


Stress Impacts Iguanas’ Appetites

Stress has a bad effect on iguanas, and the lack of appetite is one telltale sign. Here are some of the reasons why stress may cause iguanas to stop eating:

  • Uncomfy habitat
  • Being exposed to predators or wrong temperature/humidity
  • Transportation trauma – moving to a new home, shipped by mail
  • Lack of socializing with other iguanas or human contact

It’s important to know that other health issues, like metabolic bone disease, constipation, parasites, and infection, can look like signs of stress-induced anorexia.

Ways to help out include giving the iguana a safe, comfy habitat with controlled humidity and temperature. Make sure it’s big enough to not bore them. Provide water sources and hiding spots. Spend more time with the iguana to reduce isolation.

Iguanas may be herbivores, but they don’t do well with picky eaters – just like your last Tinder match.

Dietary preferences

Iguanas have diverse dietary preferences. It’s key to know this to understand why they stop eating. A balanced diet with both plants and meat is essential. Don’t overfeed or underfeed, as it will cause loss of appetite. Research what plants agree with their digestive systems. Experts at petMD say, “Iguanas have a hindgut fermentation digestive process.” Knowing dietary preferences is necessary to figure out why they don’t eat. Keeping them healthy requires a varied, balanced meal plan. Looks like these iguanas are taking their ‘hibernation diet’ to the extreme!

Seasonal changes

Weather changes can affect an iguana’s appetite. Their metabolism slows, causing them to eat less and become lethargic. In colder months, providing enough heat is essential.

Seasonal changes also affect an iguana’s behavior and mood. They may become irritable and restless, refusing food even when offered. Extra care and attention is needed to keep them healthy.

Iguanas may experience seasonal changes differently, depending on age, environment and health. Report any unusual behavior or sudden drop in appetite for medical examination.

Know the specific care needs of your iguana breed. Proactive monitoring helps identify problems early. If your iguana refuses to eat, stock up on lettuce and hope for the best!

Signs that indicate an iguana is not eating

As a reptile owner, it is vital to understand when an iguana is not eating. Poor appetite is a critical indication that something might be wrong with your pet. Here are six signs that indicate your iguana is not eating:

  • Weight Loss
  • Change in bowel movements
  • Reduced activity level
  • Less frequent urination
  • Appearance of sunken eyes
  • Change in skin texture or color

If you notice any of these signs, it is essential to consult an experienced veterinarian as they can evaluate the condition and provide appropriate treatment. Furthermore, monitor your iguana’s eating habits to prevent illness. For example, if your iguana has gone without eating for an extended period, offer water with vitamins to hydrate them. This helps to keep their energy high and enables them to recover their normal appetite.

In one instance, my friend noticed her iguana had stopped eating his favorite food and was barely moving. Being a responsible pet owner, she took the iguana to a professional veterinarian. The veterinarian discovered the iguana was suffering from an infection. After treatment, the iguana has since gone back to its normal eating habits and activities.

Looks like my iguana is taking after me on Mondays – just too tired and lazy to eat.

Lethargy and weakness

If your iguana appears weak and has a lack of energy, it could mean they’re not eating. This symptom can start off subtle and get worse over time. You may also see changes in their behavior, like avoiding social interaction or being less active.

Malnutrition, dehydration, and health conditions can cause lethargy and weakness. If an iguana hasn’t been eating for a while, their muscles will start to waste away.

Monitor other symptoms, like weight loss, no appetite, or injuries. Avian vets often check stool samples for intestinal parasites or infections.

It’s important to get veterinary help if your iguana is sick. Most medical conditions can be treated with medication or diet changes, if caught in time. Try giving them food high in water content, such as cucumbers, to keep them hydrated and encourage them to eat. If their weight loss is noticeable to others, it’s time to take them to the vet.

Loss of weight

Iguanas that appear thinner than usual can be a warning sign. Keep an eye out for these signs:

  • Loss of appetite or no interest in food
  • Refusal to eat
  • Eating less than normal, with visible weight loss
  • Reduced activity and movement
  • Avoiding sunlight or less basking time

Check for any signs of illness like diarrhea, dehydration, or constipation. Poor nutrition, malabsorption issues, or faulty heating in the habitat could cause weight loss. Diseases like metabolic bone disease or other chronic illnesses can also be serious.

One pet owner noticed gradual weight loss in their iguana but didn’t get vet care until it was too late. The vet diagnosed digestive tract malabsorption, which could have been treated earlier.

If your iguana’s skin and eyes are turning yellow, it’s time to give them something other than wheatgrass!

Changes in the skin and eyes

Lack of appetite can cause a change in the physical appearance of an iguana, especially its skin and eyes. It may have dull skin, flaking off scales, and sores. The eyes might appear sunken or swollen, signifying dehydration or infection.

The upper eyelids of the iguana can lose their blue sky color due to malnutrition or disease. It might also release white mucus from its nose or mouth due to digestive system imbalances.

If you spot these signs, check your pet’s eating routine for any changes that may indicate why they’re not eating. Not noticing these symptoms could lead to severe health issues like organ damage or metabolic bone disease.

One pet owner noticed a decrease in appetite in their iguanas after moving them to a new cage. After making some modifications to suit their natural habitat, the iguanas began eating again and got back to health soon.

Show your iguana some love and help them eat again by following these steps:

  1. Ensure that the food is fresh.
  2. Use dark green veggies or fruits as treats.
  3. Feed them a calcium-rich diet (provided by supplemental feeding, exposure to UVB lighting or both).
  4. Check the temperature and lighting in their habitat; iguanas require a warm environment to digest their food.

Steps to encourage an iguana to start eating again

Don’t expect your iguana to dine and dash if their habitat isn’t up to par.

Providing a proper habitat

Iguanas need a home environment that replicates their natural habitat for optimal health and well-being. The housing should be the right size and have adequate space, heat, lighting, substrate, and hiding spots. The temperature should be between 100-110°F for basking and 75-85°F for cooler areas. A full-spectrum UVB light is essential to produce vitamin D3. The substrate should be textured for digging and burrowing. Hiding spots create a secure environment.

Regular maintenance is necessary for iguanas. Nail trimming and other procedures must be done by a skilled veterinarian. Interested individuals should do research before taking on iguana care. And don’t forget annual check-ups from a qualified veterinarian or biologist.

Regular check-ups with a veterinarian

Regular vet check-ups are essential for your iguana’s health. Early detection and prevention of medical issues is key. Find a vet who specializes in reptilian care.

During these visits, the vet will assess your iguana’s overall health. They’ll check weight, and search for any signs of illness or disease. You should also discuss changes in behavior or diet.

Preventative care means your iguana can live a long, healthy life. Vaccines and other measures help. As pet owners, we must ensure our pets receive proper medical care. Don’t miss out on the chance to keep your iguana healthy and happy!

Maintaining optimal temperature and lighting conditions

Ensuring your iguana’s welfare is essential. This includes regulating the temperature and lighting to their physiology.

Temperature should be:

  • Basking area: 90-95°F;
  • Cooling area: 75-85°F;
  • Nighttime: No lower than 70°F.

Low temperature could lead to respiratory infections, metabolic issues or lethargy. High temperature could cause heat stroke.

Lighting intensity and duration needs to be:

  • UVB light with a range of 5-12% UVB
  • At least 10 hours per day.

If not enough lighting, your Iguana can face malnutrition due to Vitamin D3 deficiency leading to weak bones, Metabolic bone disease (MBD).

Monitor humidity levels and provide an environment that replicates their natural habitat. To keep your iguana healthy, adhere to these preventive measures and maintain optimal temperature & lighting conditions. Prevention is better than cure!

Ensuring a balanced and nutritious diet

Looking after your iguana’s health requires feeding them a nutritious, balanced diet. Careful consideration is needed when selecting food items that meet their dietary needs and provide the right balance of nutrients. Diverse greens, vegetables, fruits, insects and calcium supplements offer essential vitamins and minerals.

Calcium, vitamin D3 and low phosphorus are key for preventing metabolic bone disease. Commercial diets may be an option, but natural diets with live foods like crickets and mealworms offer better nutrition. Fresh water must be provided frequently and should always be accessible.

Iguana owners should monitor the amount and frequency of feeding. Overfeeding and underfeeding can both be harmful. Young iguanas need to be fed more often, increasing the frequency gradually.

Luke recently adopted an iguana from a reptile rescue center, who sadly passed away due to age-related ailments. He wanted to give the best care possible, so he extensively researched the diet and created nutritious recipes using naturally sourced ingredients.

Take care of your iguana – or else it might catapult off your shoulder!

Minimizing stress and handling with care

Protect the iguana’s health and welfare with gentle, low-stress handling techniques. Learn proper holding to avoid fearful and aggressive behavior.
