How Long Can Crested Geckos Go Without Food?

Crested geckos are popular pet reptiles that require special care when it comes to their dietary needs. As owners, it’s important to understand how long these unique lizards can go without food so that we can prevent health issues.

If you’re short on time, here’s a quick answer to your question: Healthy adult crested geckos can survive 10-14 days without food before their health becomes compromised. Juveniles and hatchlings should not go more than 4-7 days without eating.

In this comprehensive guide, we will cover everything you need to know about crested gecko fasting periods and how long they can safely go without food.

Typical Fasting Periods for Healthy Crested Geckos

Adults

Adult crested geckos can typically go without food for 7-10 days before needing to eat again. However, healthy adults should not be fasted for longer than 2 weeks at a time. Going too long without food can cause the gecko to burn through fat reserves and become malnourished.

Here are some key points on normal fasting periods for adult cresties:

• In nature, adult crested geckos likely go through periods of fasting due to availability of food. Their bodies are built to handle short-term fasting.
• A healthy adult gecko that is fed a consistent diet can go 7-10 days between feedings without issue. This is a normal fasting period.
• Fasting your gecko for 1-2 weeks at a time is okay on occasion, such as before brumation. But avoid fasting for longer periods.
• Monitor weight during fasting. Adults should not lose more than 2-3 grams before eating again.
• If fasting for over 10 days, provide plain calcium supplement without D3 1-2 times per week.

The main thing is to pay attention to your crested gecko’s body condition. If weight loss becomes excessive, it’s time to resume normal feedings. A healthy adult gecko should regain lost weight quickly once feeding resumes.

Juveniles and Hatchlings

Young crested geckos under 1 year old have higher caloric needs and should not go as long without food. Here are some general guidelines:

• Hatchling cresties under 3 months old should not go more than 3-4 days without food. Their rapid growth requires consistent feedings.
• Juveniles 3-12 months old can go 5-7 days between feedings. Monitor weight closely.
• Never fast juveniles for longer than 1 week at any age. This can stunt growth.
• Weigh juveniles before and after fasting to ensure weight loss is minimal.
• Provide plain calcium 1-2 times during the fast to support bone growth.

Factors That Influence Fasting Capabilities

Age

Younger crested geckos under a year old should not go more than 2-3 days without food as they are still growing and require consistent nutrients. Adult crested geckos over a year old can typically go longer without food, generally 7-10 days depending on other factors like health condition and temperature (adult crested geckos have slower metabolisms so they use up stored energy slower).

Elderly crested geckos over 5-7 years old should not go more than 5-7 days without food as their age makes them more vulnerable.

Health Condition

A crested gecko’s overall health impacts how long they can go without food. According to Moon Valley Reptiles, healthy adult crested geckos can go 7-10 days without food. Geckos that are sick, stressed or recovering from an illness should not go more than 2-5 days without food depending on severity.

Temperature and Humidity

Colder temperatures lower a crested gecko’s metabolism requiring less food intake. Humidity also impacts hydration needs. According to ReptiFiles.com, the optimal temperature is 68-78°F with 40-60% humidity.

In colder 65°F temperatures, an adult crested gecko may go 2 weeks without food by lowering its metabolism. Higher 80°F temperatures speed metabolism requiring more frequent feeding.

Last Meal and Body Condition

The size and nutrition level of a crested gecko’s last meal impacts how long they can go without food again. According to ReptiFiles, adult crested geckos should be fed 2-3 times a week. Their last meal should be nutritious and substantial.

Lean geckos with less fat stores require more frequent feeding, while healthy weight geckos can go longer between feedings.

Signs of Hunger and Stress

Increased Activity

When crested geckos start to go hungry, one of the first signs you’ll notice is an increase in their activity levels. They will start exploring their enclosure more, moving around excessively, and searching for food.

This restless behavior is a sign that your gecko is getting stressed and agitated from not eating. If the gecko goes too long without eating, this exaggerated activity can lead to weight loss and health problems.

Scratching and Pacing

In addition to moving around more, hungry crested geckos may start compulsively licking, scratching, or rubbing their faces and bodies along surfaces in the enclosure. They may also start pacing back and forth. This repetitive motion is a self-soothing behavior when a gecko gets stressed.

The licking and scratching could lead to irritation, wounds, or mouth rot if the situation continues too long. So pay attention if your gecko suddenly develops these behavioral tics, as it’s likely an indication they need food.

Weight Loss

As a crested gecko’s energy reserves start to dwindle from lack of food, one of the clearest physical signs will be weight loss. Adult crested geckos should generally weigh between 35-60 grams, depending on their size and sex.

Juvenile geckos weigh 5-10 grams when hatching and reach adult weight after 12-18 months. Weigh your gecko periodically to monitor their weight. If you notice a sudden drop or downward trend, it likely means your gecko is losing nutrition and needs to eat very soon.

Lethargy

In the later stages of hunger and starvation, crested geckos will start to become lethargic and less responsive. Whereas they previously had high activity levels while searching for food, they will now start to slow down and have little energy or motivation to move.

Your gecko may spend most of its time motionless in a single spot instead of exploring its habitat. This fatigue results from the gecko’s body conserving energy as its nutritional state declines. At this stage, it’s crucial to get food into your gecko right away to avoid serious health consequences.

Providing Food After Fasting Periods

Slow Reintroduction

After a crested gecko has gone through a period of fasting due to brumation or illness, it’s important to slowly reintroduce food. Suddenly going back to their normal feeding regimen can shock their system. Here are some tips for getting your gecko back on track after fasting:

• Offer small amounts of food at first, like 1-2 crickets or a few licks of crested gecko diet. Monitor to see if they eat it.
• Gradually increase the amount offered over the course of a week or two until you get back to their normal diet.
• Provide food every other day at first rather than daily so their digestion has time to readjust.
• Stick to their favorite foods that will entice them to eat again.
• Make sure prey items are gut-loaded and dusted lightly with supplements to provide extra nutrients.

Patience is key when reintroducing food. Rushing the process can cause regurgitation or lack of appetite. Working back up to their normal diet slowly allows their digestive system to wake up and prevent complications.

Hydration

Dehydration is a major risk when a gecko hasn’t eaten or drank water for an extended period. Providing adequate hydration is crucial along with reintroducing food.

• Provide a small, shallow water dish in the enclosure at all times. Change the water daily.
• Lightly mist the enclosure 1-2 times per day to provide drinking opportunities.
• Offer bottled pediatric electrolyte solution in a small cap for geckos that are severely dehydrated.

  Pedialyte	Contains electrolytes and glucose needed for rehydration
  Diluted juice	Natural sugars to boost energy
  Plain water	Avoid tap water which may contain chlorine

• Monitor urates to check hydration – they should be white, not yellow or stuck together.

Preventing dehydration after fasting periods gives crested geckos the water and electrolytes they desperately need to recover. Proper hydration sets them up for success when reintroducing food.

Varied Diet

Variety is important when getting crested geckos back on a normal diet after fasting. Provide a diverse mix of insects and commercial diets to give a balanced nutritional profile.

• Rotate through different feeder insects like crickets, mealworms, waxworms, and dubia roaches.
• Alternate commercial diets like Pangea and Repashy – include both fruit and insect flavors.
• Dust insects lightly with supplements like Repashy Calcium Plus for added vitamins and minerals.
• Chop and mix fruits like banana, mango, and strawberry for variety.
• Feeder insects should also be gutloaded for 24-48 hours before feeding for optimal nutrition.

After a period of fasting, crested geckos need a varied, balanced diet to regain weight and proper nutrition. Rotating through different food items keeps their appetites stimulated during recovery.

When to Seek Veterinary Care

Crested geckos can go extended periods without food, but it’s still essential to monitor their eating habits closely. If your crested gecko stops eating for an alarming stretch, be sure to seek veterinary care right away. Here’s a helpful guide on when a vet visit is absolutely necessary.

Prolonged Anorexia

Healthy adult crested geckos can go weeks without food. However, juvenile geckos should not go more than a week or two without eating. If your gecko continues rejecting food past these windows, quickly book a vet appointment.

Prolonged anorexia can lead to rapid health deterioration and even death if left untreated.

Significant Weight Loss

While some weight fluctuations are normal, a sudden considerable drop likely signals an underlying issue needing medical attention. For adults, losing over 10% of body weight warrants a vet visit. For juveniles and hatchlings still actively growing, schedule an appointment if weight stagnates or declines over a couple weeks.

Lethargy & Weakness

Lack of appetite frequently coincides with lethargy and body weakness. Geckos refusing food likely feel too sick and worn out to eat. If your previously active and eager gecko turns listless and frail in coordination, don’t delay seeking veterinary assessment.

These decrements indicate illness or injury necessitating swift diagnosis and care.

Physical Injury

Sometimes a specific injury explains a gecko’s inappetence. Cuts, mouth rot, broken bones, and eye trauma can all inhibit eating. If you notice wounds, swelling, or other overt physical damage alongside anorexia, schedule a vet visit for proper treatment, even if issues seem minor at first.

Catching injuries early better ensures full recovery.

While crested geckos are resilient, ongoing digestive upset, disease, or trauma can rapidly endanger health. If anorexia or related warning signs persist more than a couple weeks, veterinary evaluation provides the best chance for figuring out underlying problems and restoring appetite and wellness.

Conclusion

Understanding crested gecko fasting capabilities can prevent health issues caused by malnutrition and hunger stress. While adults can go 10-14 days without food, juveniles and hatchlings should eat at least every 4-7 days. Look for signs of hunger like increased activity and weight loss.

Slowly reintroduce food after fasting and seek veterinary care if geckos seem ill.
