Lizards, fascinating creatures that have become increasingly popular as pets, require dedicated care and understanding. As a responsible lizard owner, you might find yourself pondering questions like: Can my lizard survive without food while I’m away? Why hasn’t my lizard eaten in days? These concerns lead to a central question: How Long Can A Lizard Go Without Food and water? This article explores the factors that influence a lizard’s ability to survive without sustenance, providing insights to ensure your scaly companion thrives.
Factors Affecting a Lizard’s Fasting Tolerance
A lizard’s ability to endure periods without food depends on a multitude of factors, including its age, size, species, and overall health. Understanding these elements is crucial for providing appropriate care.
Age
Young lizards, still in their growth phase, have higher energy demands. Their bodies require consistent nutrition to support development and adaptation to their environment. Prolonged fasting can significantly hinder their growth. As a general guideline, young lizards should not be deprived of food for more than a week.
Size
Generally, larger lizards possess greater nutrient reserves, enabling them to withstand longer periods without eating. Medium-sized lizards can typically survive for a week to ten days without food. Some larger species, such as monitor lizards (Varanus), can endure a month or even two without sustenance. Conversely, smaller lizards and their larvae have limited energy stores and may only survive for approximately three days without food.

However, there are exceptions to the size rule. Certain lizard species, like the Gila monster (Heloderma suspectum) and the African fat-tailed gecko (Hemitheconyx caudicinctus), possess specialized tail structures that allow them to store substantial amounts of nutrients. This adaptation enables them to survive without food for extended periods, often twice as long as other lizards of similar size.
Species
Different lizard species have varying metabolic rates and adaptations to their natural environments, influencing their fasting tolerance. For example, an adult leopard gecko (Eublepharis macularius) can survive for over a month without food, whereas an adult bearded dragon (Pogona vitticeps) might only last around three weeks.
Overall Health
A lizard’s overall health plays a significant role in its ability to withstand food deprivation. Healthy lizards with robust immune systems and adequate fat reserves can typically survive longer without food than those suffering from underlying health conditions. Lizards with diseases or illnesses require more frequent feeding to maintain their strength and support their recovery.
Lizard Survival Without Water
Like all living organisms, lizards require water to survive. Dehydration can quickly become a critical issue. Generally, lizards should not be without water for more than a few days. Species adapted to arid environments, such as bearded dragons, are typically more tolerant of dehydration than those from tropical climates.

Signs of dehydration in lizards include sunken eyes, wrinkled skin, loss of appetite, and reduced activity levels. To check for dehydration, gently pinch the lizard’s skin. If the skin snaps back quickly, the lizard is likely adequately hydrated. However, if the skin returns slowly, the lizard is dehydrated and requires immediate attention. If you observe any signs of dehydration, consult a veterinarian immediately.
Reasons for Loss of Appetite in Lizards
There are several reasons why a lizard might refuse to eat, including:
- Stress: Newly acquired lizards may experience stress from relocation and require time to adjust to their new environment.
- Temperature: Lizards are ectothermic (cold-blooded) and rely on external heat sources to regulate their body temperature. Low temperatures can decrease their metabolism and appetite.
- Environmental Factors: Inadequate living conditions, such as insufficient space or improper lighting, can contribute to a loss of appetite.
- Illness: Underlying health conditions can cause a lizard to lose its appetite.
What to Do If Your Lizard Isn’t Eating
If your lizard refuses to eat, consider the following steps:
- Ensure Proper Temperature: Maintain the appropriate temperature gradient within the enclosure, providing a basking spot and a cooler area.
- Provide a Suitable Environment: Ensure the enclosure is appropriately sized and furnished with hiding spots and climbing structures.
- Offer Live Food: Some lizards are more enticed by live insects, which stimulate their natural hunting instincts.
- Minimize Stress: Provide a quiet and undisturbed environment to help the lizard adjust.
- Consult a Veterinarian: If the lizard’s lack of appetite persists or is accompanied by other symptoms, seek veterinary attention to rule out underlying health issues.
Conclusion
Understanding how long a lizard can survive without food and water is essential for responsible pet ownership. By considering factors such as age, size, species, and overall health, you can provide appropriate care and ensure the well-being of your scaly companion. Always monitor your lizard for signs of dehydration or loss of appetite, and consult a veterinarian if you have any concerns.
