For those who want a clear window into the health of their leopard gecko, they should start by monitoring their reptile’s bowel movements and poop.
This will help you realize whether there are issues with your enclosure, their diet, or if they consumed something they shouldn’t have.
Be sure to carefully monitor their enclosure for signs of healthy poop.
Healthy leopard gecko poop is typically dark brown at the bottom, with the top one-third being white or yellow (the urates). You may also see a small amount of liquid pee. Leopard gecko poop smell is typically mild and dissipates after some time in the enclosure.
For more information on the color of your gecko’s poop, this detailed breakdown will give you everything you need to know.

Healthy Leopard Gecko Poop
In healthy leopard geckos, poop should be a darker color and look similar to a sausage roll. It should generally be brown at the poop end of the bowel movement.
If you are concerned about the poop of your adult leopard geckos, you need to be aware of what a healthy bowel movement looks like.
By monitoring their stool, you will have clear insight as to whether something is bothering them or if they are unhealthy.
Normal leopard gecko poop has three components: poop, urates, and sometimes liquid pee.
As you might have guessed, the bulk of their bowel movements is typically made up of poop.
Further up, you will see a light yellow or white part known as the urates.
This is solid pee which comes out as part of their bowel movement.
In most cases, leopard geckos do not urinate to get rid of excess water.
Their bodies use every last drop because they are primarily found in desert regions with little freshwater.
Instead, they pass their uric acid and wastes from their body in a solid form known as the urates.
However, you may sometimes find a little bit of liquid pee along with their poop.
A small amount of urine is nothing to be concerned about if your gecko is relatively healthy.
It may be just a few drops and hardly noticeable, especially if the substrate in your enclosure has soaked it up.
Normal leopard gecko poop does not have a large odor.
You may notice a small smell if the healthy poop is fresh, but the smell will fade the longer it sits in the enclosure.
Most of the time, you will not notice the smell at all unless you are fairly close to a fresh stool sample.
As you might imagine, it is best to clean poop out of the enclosure as soon as you possibly can, even if it means just spot cleaning the enclosure.
Occasionally, you want to also take a stool sample to your local reptile veterinarian.
This is especially important if you just brought them home from the pet store and have other lizards in your home.
You need to collect the poop in a small plastic baggie or a plastic container.
Make sure you do not touch it with your hands when picking it up, as this can contaminate the sample.
You also do not want to use a paper towel to move the sample.
Do your best to scoop it up using just the container and lid or pick it up using the baggie turned inside out.
Store it in the refrigerator overnight until you make it to the clinic to drop off their fecal sample.
This helps to test for parasitic infections which could be passed to other reptiles in the home and to ensure the health of your leopard gecko.
It should be taken to the veterinarian for testing within 24 hours of collecting the sample.
Leopard Gecko Not Pooping
If your leopard gecko has not pooped for several days, you may need to take them to a veterinarian. They could be impacted, dehydrated, or the temperature in the enclosure may not be appropriate. Getting to the bottom of it is important for the health of the gecko.
Depending on the age of your gecko, they may defecate more or less frequently.
Hatchlings and juvenile geckos typically go to the bathroom more often.
They may even go several times a day.
A baby gecko tends to eat more, so it makes sense they would also use the bathroom more frequently.
A juvenile who goes a few days without pooping should see a veterinarian.
An adult gecko may choose to eat just once every two to three days.
As you might imagine, this means they will have less food in their system and a decreased need to poop.
They may only go to the bathroom once every several days.
If you notice your adult gecko has not gone to the bathroom in seven to eight days, there could be something seriously wrong with your reptile.
This should be cause for concern.
A new gecko may still be stressed out from the move to a new location and enclosure.
This could result in a lack of appetite for the first week or so.
If you recently purchased your gecko and it has yet to go to the bathroom, it may not be a huge concern just yet.
Keep an eye on it and do your best to encourage them to eat.
If the problem persists, consider taking them to an experienced reptile veterinarian to investigate the issue and ensure there is no other reason for their lack of appetite.
If your gecko is not new and still has not pooped in seven to eight days, it is time to take further action.
It could be the result of impaction, dehydration, or improper tank temperatures.
Impaction is a fancy term meaning there is some type of blockage in the digestive system.
In most cases, this is caused by a gecko who consumed loose substrate such as sand from the bottom of their enclosure.
This loose substrate blocks their digestive system and keeps them from being able to go to the bathroom.
It might be quite uncomfortable for them and needs to be addressed.
You may want to give them a warm bath while gently massaging the belly area.
This can sometimes help to pass the blockage, but it is not always successful.
If this does not help your leopard gecko, you need to take them to a veterinarian to potentially schedule a surgery to remove the loose substrate or whatever is blocking them.

Another cause of not pooping is dehydration.
Many geckos will get a lot of the water they need from the insects they consume.
However, they still need to drink water from their dish as well. If your leopard gecko has been avoiding their freshwater, it could result in dehydration and prevent them from pooping.
Moisture is needed to get the stool to pass properly through the digestive system.
Without enough water in the diet, a dehydrated leopard gecko will have a harder time getting waste to leave the body.
Usually, it is easy to spot dehydration in your gecko. It typically results in sunken eyes, folded skin, or wrinkles.
If they pass some poop, you may notice it does not contain any urates (the white or yellow part of the stool).
This is often a key indicator your leopard gecko is not getting all the water they need in its diet.
Incorrect Tank Temperature
Many new reptile owners are unaware of just how important the proper temperature gradients are in your enclosure.
Leopard geckos rely on temperature from the ground to help process food through their digestive system.
If the heat is too low, you might have a gecko who cannot digest his food properly and therefore has no bowel movements.
During the day, your enclosure should be close to 90° degrees Fahrenheit (32° C) on the warm side of the tank.
The cool side should be about ten degrees cooler at 80° degrees Fahrenheit (27° C).
This temperature can dip into the 70° degrees Fahrenheit (21° C) range during the nighttime.

Leopard Gecko White Poop
Many owners mistake urates for white poop. However, if the poop is white, it could be from the gecko eating its shed and resolve in a few bowel movements. White poop also indicates they may have eaten some loose substrate such as sand.
If you notice your leopard gecko has white poop, there are a few reasons this can occur.
First, you need to make sure you are not looking at urates.
This white to yellow excretion is a normal part of a healthy bowel movement for your gecko.
The urates generally are about one-third the size of the feces.
Sometimes, your gecko may have an all-white poop, but it may not be anything to be concerned about.
One of the most common reasons for white poop is what they ate.
If they recently had a shed, they may have digested their discarded skin.
The result is white poop, but it is nothing to be concerned about.
It is just the undigested part of their skin.
Their poop may be white or grey if this is the culprit.
A more worrisome reason for white poop is if they have been consuming loose substrate.
Consider what you have been using as a substrate in your enclosure.
Light substrates such as sand can lead to impaction.
As your leopard gecko attempts to pass the obstruction, it may come out as white poop.
If you notice this happening, the best thing to do is switch the substrate to something they cannot consume, such as ceramic tile.
Impaction is a serious issue often requiring surgery, so you need to take every available precaution to keep this from occurring.
Leopard Gecko Grey Poop
Grey leopard gecko poop is often caused by eating shed skin. It should resolve itself within two to three bowel movements if this is the case. If it does not resolve itself, there may be excess calcium or minerals in your gecko’s diet which need to be adjusted.
It is not uncommon to find your leopard gecko has grey or clay-colored poop as well.
Fortunately, this is nothing to be concerned about.
It frequently happens due to consuming their shed and should resolve itself in a matter of days.
Leopard geckos love to eat their sheds, so just be sure to keep an eye on this behavior.
If they recently lost their skin and then have grey poop, this is likely the culprit.
Another common culprit of grey poop is excess calcium or minerals.
If you frequently feed calcium-dusted insects or add supplements to your gecko’s food, this grey poop could be the result.
Consider whether you have recently made any changes to your gecko’s diet, which would result in him receiving an excess of calcium or some other mineral.
You may want to attempt to modify their diet and cut back on any supplementation you have been using to see if the poop returns to dark brown color with the white or yellow urates.
If you are a new owner, balancing your gecko’s diet is a bit overwhelming.
There are no real one-size-fits-all answers for how much calcium is too much for your gecko.
It is very much an individualized process to figure out what works for them.
It might be helpful to book an appointment with an experienced veterinarian to review the diet you have been giving them and see if there is any way to improve on it for the overall health of your leopard gecko.
Leopard Gecko Green Poop
Green leopard gecko poop may be caused when your pet eats green substrates such as moss or colored sand. A change in diet might result in loose, green stool as well. If the problem does not resolve itself quickly, you may look at parasitic or bacterial infections, which should be looked at by a veterinarian.
Green poop can have many causes.
The first consideration is they may have ingested some of their substrates.
You need to think through what is included in their enclosure to determine if they could have ingested something to cause their green stool.
Colored sand, moss, and even paper towels can all be behind the green poop.
It might be harder to tell if this is the cause if you recently purchased your leopard gecko.
It might be worth making a phone call to the pet store or the breeder to find out what substrate was in the enclosure at the last location.
This can give you key information about just what your gecko may or may not have ingested.
Another common cause of green poop is a change in diet.
Even a healthy gecko may struggle to adapt to a new diet.
The flora in their gut needs time to adjust to the change.
In the meantime, they may have a more difficult time digesting their food, causing it to run through their digestive tract faster than usual.
This often results in diarrhea.
Why does this cause the poop to turn green?
This occurs because the bile from the gallbladder, which helps digest the food, does not have an opportunity to get broken down.
As a result, the green color of the bile colors diarrhea and comes out as green poop.
While white and grey poop may not be concerned about, green poop is a different story.
It will often turn green if there is something majorly wrong with your reptile.
In some cases, green stool indicates they may have some type of parasitic infection.
Give your reptile a chance to work through the other potential causes.
If they still have green stool in a week or so, then you need to take them to the veterinarian to have their infection treated.
Leopard Gecko Yellow Poop
Yellow poop, particularly the urates, is often caused by either dehydration or too many vitamins. Consider adjusting your enclosure to give them access to more water or moisture, as well as changing their diet to correct this issue. Parasites may also cause yellow poop.
While it could be normal to have a slight yellow tint to the urates at times, an overwhelming yellow color usually indicates dehydration.
Some owners do not feed their leopard geckos daily, which means they may not inspect the cage daily.
As a result, your gecko may be low on water for a day or two until you feed them again.
Make an effort to check their water dish daily.
They also need a moist hide to help restore water to their bodies.
Either purchase or repurpose a container to be used as a hide.
If repurposing a container, be sure to cut a large hole in it for your gecko to enter and exit from.
Make sure there are no jagged edges that could cut your gecko’s skin as they crawl over it.
Line the hide with a substrate that holds moisture but does not grow mold easily, such as moss or paper towels.
You should always place it on the warm side of the enclosure.
Fortunately, telling whether your leopard gecko is dehydrated is rather simple.
Beyond yellow poop, they frequently exhibit other symptoms of dehydration.
For example, they may have sunken eyes or a type of sticky mucus in their mouths.
If it is shedding time, they may have difficulty getting their shed off completely in one piece as they usually do.
Sometimes, yellow poop is a sign your gecko is receiving too many vitamins.
Consider whether you recently changed their diet, such as dusting feeder insects with calcium powder or something similar.
If so, then you may be looking at an excess of vitamins.
Either consult a veterinarian about the dietary changes or switch back to feeding them before the yellow stool.
Of course, yellow poop could also be a sign of a parasitic infection.
It is best to collect a fecal sample from your gecko and take it to the veterinarian for testing.
Remember not to touch the sample with your hands.
Pick it up in a plastic baggie or place it in a plastic container for transport.
Keep it in the refrigerator for up to 24 hours before taking it to the vet.
Never place it in the freezer.
Undigested Insects And Leopard Geckos
Undigested insects in leopard gecko poop might be a result of improper basking temperatures in the enclosure. It could also be caused by internal parasites or impaction. Evaluate their surroundings and consider taking a stool sample to the veterinarian.
In addition to differently colored stool samples, you might also notice undigested insects in their poop from time to time.
One of the most common reasons for this is improper conditions in the enclosure.
If the basking area is not warm enough, it can interfere with their digestive tract.
The ideal temperature for the basking area should be between 87 to 90° degrees Fahrenheit (32° C).
Undigested insects in the poop may be caused by impaction.
Be sure to inspect the poop to see if there is any substrate in the droppings.
This only applies if you are using a loose substrate such as sand.
If you find signs of the substrate in the poop, then switch to a different substrate such as tile or paper towel.
Last but not least, this might be caused by internal parasites interfering with the digestive process.
If the issue persists beyond one or two bowel movements and the other factors are not causing it, be sure to collect a sample and take it to the veterinarian for testing.
