The Curse of Overhydration in Chameleons

BEWARE   THE   PICTURES   DEPICT   WRONG   PRACTICES   -   NOT   TO   BE   FOLLOWED!!!

Ensuring Proper Hydration for Captive Chameleons

In the realm of chameleon husbandry, one of the most common challenges is ensuring proper hydration levels. Maintaining a delicate balance in hydration is critical because both dehydration and overhydration can have severe negative impacts on a chameleon's health. In recent years, utilizing a combination of hydration methods has become the recommended standard in captive care, promoting optimal health and well-being for these fascinating reptiles.

To prevent issues related to hydration, the following methods are commonly employed:

DO NOT LET THE CHAMELEONS DRINK FROM TAP, SPRAYER OR BOTTLE!

It's crucial to understand that heavy water intake in a short period can be extremely harmful and dangerous. Forcing a chameleon to drink large amounts of water, especially after evident dehydration, is a bad practice. Under the misguided notion of rehydrating a dehydrated chameleon, you might inadvertently cause severe health issues. The average amount of water consumed by a 100 g chameleon in a very dry environment is approximately 1 ml. In cases of severe dehydration, the maximum amount for rehydration can double to a maximum of 2 ml per 100g of body mass. To put this into perspective, this amount is roughly equivalent to one and a half liters of water for an average human. Forcing a chameleon to drink 5 ml or even 10 ml of water would be comparable to forcing a human to drink 2 to 3 gallons of water at once. Such practices are reminiscent of medieval torture methods used to punish people with cruel and painful deaths; therefore, please do not subject chameleons to this kind of treatment. 

"Another concerning method of forcefully hydrating chameleons is the use of hand misters. On social media, there are numerous examples of irresponsible breeders and inexperienced keepers claiming to hydrate chameleons by spraying water from a distance of just a few millimeters directly into their mouths or attaching the nozzle to the chameleon's mouth. This is an extremely dangerous practice that can lead to water entering the lungs, as the pressurized water can easily reach the trachea. When a chameleon takes in a mouthful of water, it may also inadvertently inhale air, which can cause it to draw in excessive amounts of water. Hypotonic water can damage the lungs, impairing their function and potentially leading to respiratory infections and even death in severe cases. Therefore, this method of hydration is not recommended under any circumstances."

Moreover, if a chameleon feels liquid in the mouth, it starts to swallow reflexively and is practically unable to stop. Therefore, providing them water cannot be regulated by them, and continuous supply of it into the mouth cavity causes over-hydration. When a chameleon is dehydrated and then suddenly saturated with water, several detrimental effects can occur:

1. Kidney Damage:

   A lack of water sets the kidneys to a state of too high concentration of fluids. An abrupt increase in water can bypass their function, leading the kidneys to limit or stop filtering properly, potentially resulting in kidney failure.

2. Intestinal Damage:

   A large amount of water in the intestines is hypotonic compared to the osmotic properties of the chameleon's internal environment, causing osmosis that may lead to the tearing of intestinal cells (enterocytes). This can impair intestinal function, limiting nutrient absorption, and result in poorly formed feces that decay, producing harmful toxins. The dead cells in the intestinal walls can serve as a breeding ground for bacteria, leading to inflammation. The visible result can be sluggish, light brown or grey, watery excrement with a very intense foul smell, coupled with watery, whitish urate that may lack orange crystalline deposits.

3. Disruption of Homeostasis:

   Excessive water intake can severely disrupt homeostasis. Osmosis might cause cell rupture in many organs, including the intestines and vessels, while the dilution of enzymes to low concentrations can inhibit or stop their physiological functions.

4. Electrolyte Imbalance:

   Dehydrated chameleons can experience electrolyte imbalances, which affects various bodily functions. Rapid rehydration with excessive water can further exacerbate these imbalances, leading to health issues such as muscle weakness, cramping, or cardiovascular problems.

5. Shock:

   If a chameleon is severely dehydrated and then suddenly given a large amount of water, it may go into shock. This is particularly true if the body cannot adjust to the sudden influx of fluids, resulting in acute stress and potentially leading to fatal outcomes.

6. Bacterial Infections:

   Rapid changes in hydration can create an environment conducive to bacterial growth, particularly if intestinal damage occurs. Compromised intestinal walls from swelling and osmotic shock can lead to leaky gut syndrome, increasing susceptibility to infections.

7. Organ Stress:

   Overhydration can place stress on various organs other than the kidneys, including the liver and heart. These organs work hard to filter and circulate the excess fluids, which can lead to dysfunction or failure over time.

8. Behavioral Changes:

   Chameleons under stress from dehydration or improper rehydration may exhibit changes in behavior, such as increased hiding, lethargy, sensitivity or aggression. These behavioral shifts can further impact their overall health and well-being.

9. Mortality:

   In the most severe cases of improper hydration, both dehydration and overhydration can lead to death, particularly if medical intervention is not provided in a timely manner. Rapid changes in hydration status can precipitate a critical health crisis that may not be survivable.

Given these potential consequences, it is vital to establish a proper hydration system using a well-structured and combination of methods adjusted based on observations:

1. Nighttime fogging under 18°C

2. Misting before lights turn on and after they turn off

3. A dripper system as a backup

In cases of moderate dehydration, rehydration must happen slowly, with a maximum of 2 ml of water per day for a 100 g chameleon, ideally supplemented by intense nebulization and fogging along with limited but increased water intake.

In instances of heavy dehydration, the same method should be applied; however, the liquid provided orally (and possibly subcutaneously by a veterinarian) must not be hypotonic water but rather a physiological saline solution, with a concentration of 0.9 g of NaCl per liter of water.

Proper hydration for captive chameleons is essential for maintaining their health and vitality. By respecting their biological needs and establishing a thoughtful approach to hydration—featuring nighttime fogging, regular misting, and careful water delivery—chameleons can thrive in a healthy environment, avoiding the dangers of improper hydration practices.
