A crested gecko is one of the easiest pets to have. They are easy to take care of and even beginner pet owners can handle crested geckos. Their eating habits just add to the accuracy of this fact.

How long can a crested gecko go without eating food or water?

A crested gecko can go without food for up to 3 weeks! However, it is advisable to consult a vet after 2 weeks of your crested gecko not eating.

When it comes to water, however, a crested gecko can only go 3 days before getting severely dehydrated.

How Often Do Crested Geckos Eat?

It isn’t uncommon for reptiles to only eat every other day. The same holds true for your crested gecko.

You only need to feed it every other day – it does not eat every day. The frequency of eating depends largely on the crested gecko’s age.

Hatchlings (0 to 2 months): they need to eat 6 to 7 times per week after their first molting.

Baby Juveniles (2 to 6 months): they need to eat 5 to 6 times per week.

Juveniles (6 to 12 months): they need to eat 4 to 5 times per week.

Sub-adults (12 to 18 months): their food consumption drops drastically to only 3 to 4 times per week.

Mature adults (18 months and above): they eat only 2 to 3 times per week.

How Long Can A Crested Gecko Live Without Food Or Water

Just like their frequency of eating, the tolerance of going without food also changes with crested geckos’ age.

However, when it comes to water, a crested gecko at any age can only go without water for a maximum of 3 days – and for the younger ones, the tolerance is even lower.

They are prone to getting severely dehydrated without a regular supply of water every day

Baby

Hatchlings (0 to 2 months): hatchlings of crested geckos can go for only 2 to 3 days without eating after their first molting.

Some crested gecko hatchlings may take up to 6 days, but it is advisable to consult a vet after the 3rd day.

Juvenile

Baby Juveniles (2 to 6 months): Baby juveniles can go for a maximum of 5 days without eating, but it is advisable to consult the vet after 3 days.

Juveniles (6 to 12 months): Juveniles have a slightly higher tolerance. They can go for up to a week without eating. However, it is advisable to consult a vet after the 5th consecutive day of not eating.

Adult

Sub-adults (12 to 18 months): They can go for 10 to 14 days without eating; however, you should consult the vet after a week of not eating.

Mature adults (18 months and above): As age increases, so does the crested gecko’s tolerance to going without food. A mature adult crested gecko can go for up to 3 weeks without eating.

However, it is advisable to consult a vet after 2 consecutive weeks of not eating.

Can Crested Geckos Go A Week Without Food?

It highly depends on the age of your crested gecko. If your crested gecko is above 18 months of age, you don’t have any reason to worry.

However, for geckos below the age of 18 months, it is better to consult a vet if your crested gecko hasn’t been eating for a couple of consecutive days.

Is A Crested Gecko Able To Starve Itself To Death?

No, a crested gecko will not starve itself to death unless there are some underlying factors such as environmental stress or health problems.

The crested gecko might not eat for a short while if it has enough energy stored up.

But once that energy is used up, it will not starve itself. It will eat again. If it doesn’t eat for a prolonged time, you should consult a vet.

How Long Does It Take For A Crested Gecko To Start Starving?

A mature crested gecko will starve after 3 weeks of not getting any food or not eating. The time, however, is lower for younger crested geckos.

A baby crested gecko, for instance, in the age group of 0 to 2 months, can barely go for 3 days without food.

A juvenile in the age group of 6 to 12 months can handle 7 days of not getting any food but will starve after a week.

Can I Leave My Crested Gecko For A Week Alone?

No, it is not recommended to leave your crested gecko alone without any caretaker to check up on them from time to time.

While a mature adult crested gecko of over 18 months of age can go without food for a week, there are many other things that need to be taken care of.

The most important thing to consider is your crested gecko’s water bowl.

It is well established that a gecko cannot go without water for more than 3 days. So, not only do you need to ensure that the crested gecko has a lot of water, you also need to ensure that it is clean.

There needs to be someone to ensure that if the crested gecko has somehow dirtied the water bowl, it is being cleaned and refilled with clean drinking water.

Moreover, you cannot leave a lot of live food or even prepared food in your gecko’s enclosure for a long time. The live food, such as crickets, when in large numbers, will bite your crested gecko.

The prepared food will soon become a breeding ground for harmful microbes in that humid environment of the enclosure.

All in all, if you do have to go somewhere for a week and you cannot take your crested gecko along, have some friend or family member check in on the gecko at least every other day.

You can even get a pet sitter for that matter.

Can Crested Geckos Survive Without Eating Live Food?

Yes, a crested gecko can not only survive but live a healthy life even without live food. You do not need to feed live food to your crested gecko.

Only using prepared food and a mix of fruits and canned or frozen insects will do just fine to ensure your crested gecko’s health.

Why Would A Crested Gecko Refuse To Eat?

There are several reasons why a crested gecko would refuse to eat or suddenly stop eating.

Environmental Stress

It is very common for crested geckos to stop eating for a while when they are placed in a new environment.

In such times, you need to ensure that the habitat meets all temperature, humidity, and other niche requirements for your crested gecko’s comfort.

Social Stress

Crested geckos are very solitary beings. They usually do not fare well in cohabitation.

However, if your crested geckos are already in a group, and one of them stops eating suddenly, the reason behind it could be bullying.

Check for any scratches or bites on your gecko. Observe the behavior of the group. If the said gecko is being bullied, transfer it to a different enclosure.

After acclimatizing in the new tank, your crested gecko will resume eating.

Shedding or Molting

Crested geckos, like most reptiles, are known to regularly go through the process of shedding their skin. During shedding, they do not eat anything.

Impaction

Impaction happens when your crested gecko eats something, cannot digest it, and the food gets stuck in its digestive tracts.

This is a very dangerous condition and you should consult a vet if you see any symptoms of impaction.

The symptoms of impaction include a sudden weight gain and a very swollen belly, along with constipation.

A crested gecko must have bowel movements 3 to 4 times a week.

Health Conditions

From parasites to mouth rot and ulcers, a lot of underlying medical conditions can make your crested gecko stop eating abruptly. Look out for symptoms such as vomiting, diarrhea, bad smell of feces, and lethargy.

If your crested gecko shows many additional symptoms along with not eating for more than 2 weeks, you should consult a vet.

Summary

Crested geckos are pretty hardy and can go without food for about 3 weeks.

However, it is important to look out for any other symptoms and rule out any causes of discomfort as the reason behind your crested gecko not eating.

When it comes to water, crested geckos can barely go for 3 days without fresh drinking water.

So, ensure that there is a regular supply of clean drinking water for your crested gecko.
