Illness and Medical Conditions

Common Illnesses

Common Illnesses

  • Parasites: Internal and external parasites can cause digestive issues and loss of appetite in Crested Geckos. Common parasites include worms, mites, and ticks.
  • Respiratory Infections: Geckos that are kept in environments with poor ventilation or improper humidity levels can develop respiratory infections. Symptoms include wheezing, coughing, and a lack of appetite.
  • Metabolic Bone Disease: This condition occurs when a gecko does not receive enough calcium in its diet, leading to weakened bones and muscle issues. Crested Geckos with metabolic bone disease may have difficulty eating and exhibit signs of weakness.
  • Fungal Infections: Fungal infections can affect the gecko’s mouth and digestive system, causing pain and discomfort that can lead to a loss of appetite.
  • Digestive Issues: Geckos can experience constipation or impaction, which can be caused by inadequate diet or ingestion of foreign objects. These digestive issues can result in a decreased appetite or refusal to eat.

Medical Treatments

If a Crested Gecko is not eating due to an illness or medical condition, it is crucial to seek veterinary care. A veterinarian will be able to diagnose the specific issue and provide appropriate treatment. This may include medications to treat parasites or infections, dietary changes to address nutritional deficiencies, or other interventions to improve the gecko’s overall health.

Monitoring the gecko’s eating habits and seeking prompt veterinary care can help identify and address any underlying illnesses or medical conditions that may be causing a loss of appetite. With proper care and treatment, most Crested Geckos can recover and regain their appetite.

Crested Gecko Not Eating: Dental Problems and Oral Health

One of the possible causes for a crested gecko not eating is dental problems and poor oral health. These small reptiles rely on their teeth to eat, so any issues with their dental health can affect their ability to consume food properly.

Dental problems in crested geckos can arise from a variety of factors. One common issue is the presence of dental abnormalities, such as misaligned or overgrown teeth. These abnormalities can make it difficult for the gecko to close its mouth properly or to chew and break down food effectively.

Poor oral hygiene can also contribute to dental issues in crested geckos. If their mouth is not kept clean, bacteria can accumulate and lead to infections or inflammation, which can cause discomfort and make it painful for the gecko to eat.

So, what can you do if you suspect dental problems in your crested gecko?

  • Consult a reptile veterinarian who specializes in crested geckos. They will be able to examine your gecko’s teeth and oral cavity and diagnose any dental problems.
  • If misaligned or overgrown teeth are identified, the veterinarian may recommend a dental trimming procedure. This involves carefully and safely filing down the teeth to a proper length, allowing the gecko to eat more comfortably.
  • It is also important to maintain good oral hygiene for your crested gecko. Clean its mouth regularly by gently wiping it with a damp cloth or using a toothbrush specifically designed for reptiles. This can help prevent bacterial infections and promote overall oral health.
  • Provide a varied and appropriate diet for your crested gecko. Offering a diet that includes calcium-rich foods, such as insects dusted with calcium powder, can help support good dental health.
  • Ensure proper environmental conditions for your gecko, including temperature and humidity levels. Incorrect conditions can contribute to overall health issues, including dental problems.

How Temperature and Humidity Levels Affect a Crested Gecko’s Appetite

A common concern among crested gecko owners is when their gecko is not eating. There can be several reasons behind this behavior, but one important factor to consider is the temperature and humidity levels in their enclosure.

Crested geckos are ectothermic, which means they rely on their environment to regulate their body temperature. If the temperature in their enclosure is too low or too high, it can negatively affect their appetite. Ideally, the temperature should be maintained between 72-78°F (22-25°C) during the day and slightly cooler at night.

In addition to temperature, humidity is also crucial for the well-being of crested geckos. These reptiles require a humidity level of 50-70% to thrive. If the humidity in their enclosure is too low, it can lead to dehydration and cause them to lose their appetite.

When the temperature and humidity levels are not within the optimal range, crested geckos may enter a state of torpor, where their metabolism slows down and they become less active. During this time, their appetite may decrease, and they may refuse to eat.

If you find that the temperature or humidity levels are not within the appropriate range, there are several steps you can take to rectify the situation. Adding a heat mat or a ceramic heat emitter can help raise the temperature, while misting the enclosure with water or using a reptile humidifier can increase the humidity.

Gecko Not Eating: Causes and Solutions

When a gecko is not eating, it can be a cause for concern for pet owners. One possible reason for this behavior is related to mating and breeding behavior.

Mating and Breeding Behavior

When geckos reach sexual maturity, they may go through a period where they lose their appetite. This is especially common in male geckos during the breeding season. During this time, their focus shifts towards finding a mate and reproducing, rather than eating. This can result in a decrease or complete loss of appetite.

In some cases, the loss of appetite during mating and breeding behavior may be accompanied by other behavioral changes. Male geckos may become more territorial or aggressive towards other males, while females may show signs of receptivity and interest in mating.

Crested Gecko Not Eating: Anxiety and Behavioral Issues

One of the reasons why a crested gecko may not be eating is due to anxiety and behavioral issues. Just like humans, crested geckos can experience stress and anxiety that can affect their appetite and overall well-being.

There are several factors that can contribute to anxiety and behavioral issues in crested geckos. One of the most common causes is improper handling or environmental conditions. If a crested gecko is constantly being disturbed or feels threatened in its enclosure, it may become stressed and refuse to eat.

Another factor that can contribute to anxiety is the lack of proper hiding spots or enrichment in the enclosure. Crested geckos are arboreal creatures and they need vertical spaces and foliage to feel secure. Without these essential elements, they may become anxious and refuse to eat.

To address anxiety and behavioral issues in crested geckos, it is crucial to create a calm and stress-free environment. This can be achieved by providing plenty of hiding spots, vertical spaces, and foliage in their enclosure. Avoid excessive handling and try to establish a routine to reduce stress.

Additionally, consider the temperature and humidity levels in the enclosure. Crested geckos thrive in moderate temperatures and high humidity. If these conditions are not met, it can contribute to anxiety and appetite issues.

Dehydration and Water Sources for a Crested Gecko Not Eating

A common issue that can cause a crested gecko to stop eating is dehydration. It is essential to ensure that your gecko has access to proper hydration and water sources to maintain its health.

Firstly, it is crucial to provide your crested gecko with a clean and fresh water source at all times. You should use a shallow dish that is easily accessible for the gecko to drink from. Ensure that the dish is cleaned regularly to prevent the build-up of bacteria or contaminants.

Additionally, you can consider using a misting system or spray bottle to provide humidity and facilitate drinking for your gecko. Crested geckos are arboreal, meaning they primarily live in trees, so they may be more inclined to drink water droplets from foliage or their environment. Mist the enclosure lightly to create dew-like droplets that the gecko can drink from.

In some cases, a crested gecko may refuse to drink from a dish or misted water droplets. In such instances, it may be necessary to consider alternative hydration methods like offering water through a dropper or utilizing a reptile hydration gel. Consult with a veterinarian or reptile specialist to determine the best options for your gecko.

If you suspect that your crested gecko is dehydrated, there are a few signs to look out for. These signs include sunken eyes, wrinkled skin, and lethargy. If you observe these symptoms, it is crucial to address the dehydration issue promptly.
