How Do I Keep My Reptile from Overheating?
Reptiles are cold-blooded creatures, soaking up the sun to regulate their body temperature. But this doesn’t mean that they love ALL heat. As the temperatures climb outside, your reptile’s enclosure can quickly become dangerously hot, leading to serious health issues.
This blog post will be your summer survival guide, packed with tips and tricks to keep your best friend cool and comfortable all summer long.
What Happens if a Reptile Gets Too Hot?
Overheating, or hyperthermia, occurs when a reptile's body heat rises dangerously high due to outside sources, and they are unable to adjust as necessary to bring it back down to a safe level.
As cold-blooded animals, reptiles rely on outside influences for their temperature. If they are too cold, they seek heat. Likewise, if they are too hot, they seek a cooler area. However, if no cool space is available, their body temperature will continue to climb.
Overheating can lead to dehydration, tissue/organ damage, or organ failure. Just as heatstroke can be fatal in dogs and cats, overheating can also be life-threatening for our reptile friends.
What Temperature is Too Hot for Reptiles?
Each reptile species has its own ideal temperature. For example, according to the Merck Veterinary Manual, the Greek tortoise thrives most in temperatures between 68 and 82 degrees Fahrenheit. However, the green iguana prefers warmer temperatures, between 84 and 91 degrees Fahrenheit. These temperatures reflect the reptile's typical natural environment.
You will need to research the specific species to determine what temperatures are safe for your reptile and what are considered too hot. You can do this by looking up that information online, but ensure you only trust a reliable source.
Another great way to find out your pet's ideal temperature is to speak with your exotic animal veterinarian. If you don’t already have a vet specializing in exotic animals like reptiles, this is the perfect opportunity to start your search. The Association of Reptile and Amphibian Veterinarians database is a great place to start!
How Do I Know if My Reptile is Too Hot?
While there are thermometers and other gear specifically dedicated to monitoring the temperature of your reptile’s enclosure, you should also familiarize yourself with the signs that something may be “off” with your pet.
Gear fails, and accidents happen. Your reptile may also overheat at a lower temperature than usual due to a medical condition or other extenuating circumstances. If your thermometer stopped working tomorrow, would you know the warning signs to watch out for?
The most common signs of overheating and heat stroke in reptiles include:
- Loss of appetite or complete refusal to eat
- Lack of or decreased bathroom activity
- Heavy panting or rapid breathing
- Shakiness
- Wobbly/unbalanced movement or staggering
- Inability to perch
- Appearing disoriented
- Loss of consciousness
If you notice any of these signs, don’t ignore them. Overheating is extremely dangerous for reptiles, even more so than the risk of getting too cold. Act fast to cool down at least one area in their enclosure to provide a safe place before the problem escalates to dangerous levels.
Tips for Keeping a Reptile from Overheating in the Summer
Heat-related illnesses in reptiles can quickly spiral into life-threatening situations. While we should be aware of the signs and symptoms of overheating, the best approach is to prevent a problem from developing. Here are some tips and tricks to keep your reptile from overheating in the summer season, including solutions for heatwaves, power outages, and more:
Have a Thermometer (and a Backup)
One of the most important things you can do when setting up your reptile’s enclosure is to ensure that it is equipped with a reliable thermometer to monitor the temperature at all times. Many reptile lovers prefer a digital thermometer that is easy to read across the room and includes a humidity gauge. The Zoo Med Labs Digital Thermometer Humidity Gauge is a great solution.
However, I also recommend picking up an analog thermometer like the Exo Terra Thermometer as a backup. You may never need to use it, but if technology fails (as we know it sometimes does), you will be thankful that you have a backup in place.
Position the Enclosure Strategically
Consider the enclosure's location. You may need to take extra precautions during a power outage or heat wave. Consider moving your reptile away from any windows or doors that may be “hot spots” for warm air or sunshine entering the room.
You may even need to move the enclosure to a different room than usual if that happens to be the coolest spot in your home. For example, basements generally run much cooler during a power outage when you can’t rely on air conditioning units.
Double-Check for Ventilation
Ensure that your reptile’s enclosure allows proper ventilation, especially during the warmer months. Still air can quickly become hot and stale, and an enclosure with poor ventilation can quickly experience temperatures much higher than the air in the room surrounding it.
Verify that your enclosure offers opportunities for airflow, like a mesh roof instead of a solid roof. Additionally, make sure that these spots aren’t covered or blocked. If your pet’s enclosure has airflow spaces on the side, you will need to check for potential blockages outside and inside the enclosure in case something has been knocked over or moved, creating a barrier.
Block Sources of Outside Heat
While it’s common sense, I can’t skip reminding you to block any heat sources or direct sunlight, like a window or door. Close any curtains to keep the sunlight out. If you don’t have curtains on a window or glass door, consider other options like hanging a sheet, posterboard, or tinfoil to block the window. It may not look the fanciest, but the concern at that point should be more focused on function than appearance.
Another source of heat that is often overlooked is the crack under some doors. This isn’t going to invite direct sunlight, but it can allow warm air to come into the room, raising the temperature inside quickly. Roll up a towel or piece of clothing and place it at the bottom of the door, tucking it up against the opening to prevent airflow.
Power Down Unnecessary Electronics
Obviously, this isn’t a concern during a power outage – but if you still have power during a heat wave, take note of which electronics are running in your space. Electronic devices like televisions and computers generate heat when they are running. Depending on the type of lightbulb you are using, the same can be said for unnecessary lighting.
If anything is running in the same room where your reptile is kept, and you aren’t actively using it, shut it down.
Try Running Fans
Fans can help with airflow in the room by moving cool air past your reptile’s enclosure. Set them up so they blow the air along the glass side of the enclosure. If you have ice available, you can also place a small bowl of ice in front of the fan to cool the air it is moving.
Be careful blowing not to blow the fan directly into the enclosure. This could disturb the space, creating further problems.
If you currently have no power, there are some great battery-powered fans that are often used by the camping community. In addition to taking them camping, we keep a couple at home ready for situations like this. Several styles are available, but I love and use the O2COOL Treva 10-inch fan.
Spray Cool Water in Your Reptile’s Enclosure
Gently mist in and around your reptile’s enclosure. This will work like a cooling vest or bandana commonly used by dogs—as the water evaporates, it will lower the temperature around it. Be careful not to soak the space or use cold water that could shock your pet. Use cool room-temperature water.
Another way to leverage evaporative cooling is by using a damp towel or cloth.
Place the damp cloth against the glass of the enclosure. Keep it spread out, don’t allow it to bunch up, or it will be counterproductive. If you are using fans, position them to blow onto the towel. As the water evaporates, it will cool the glass, which will, in turn, cool the air inside.
Place Ice on the Mesh Roof
Does your reptile’s enclosure have a mesh roof? If so, it is the perfect setup for ice blocks to cool the space down. You don’t want to place ice in the enclosure where your pet can reach it, or you risk them getting too cold or into shock. However, you can place ice blocks or bowls/containers of ice out of their reach on the mesh roof.
As you likely already know, hot air rises, and cool air drops. This means the cool air around the ice block will drop into the enclosure, helping to bring the temperature inside down slightly.
If using this approach, pay careful attention to moisture and condensation. While a bit of moisture finding its way into the enclosure can be helpful, as it will act like the sprayed water mentioned above, too much could lead to trouble. Consider placing a thin cloth or towel directly beneath the bowl or container to serve as a barrier while still allowing air movement.
Introduce Water in Natural Substrates
Reptile enclosures with soil and other natural substrates allow you to create an environment like the one your pet would seek out in the wild. This is done by dampening the soil itself slightly.
The top layer of soil will dry out quickly on a hot day, but any excess moisture beneath the surface will remain. Even pet reptiles who have lived their lives entirely in captivity will instinctively know to dig or burrow down below the warm, dry soil to find the damp, cool layer below.
Final Thoughts: Keeping Your Reptile Comfortable
Reptiles are often viewed as easy to care for because they live in confined environments, but the temperature of your pet’s enclosure can make all the difference for its health and quality of life. This includes both minor changes that can cause discomfort and more significant temperature changes that can lead to life-threatening consequences, like hyperthermia.
As pet parents, it’s our job to familiarize ourselves with the warning signs of trouble, including changes in appetite, shakiness/loss of balance, disorientation, changes in bathroom habits, and loss of consciousness.
If you are struggling through a heat wave this summer and your home is getting too warm for you, there is a good chance it is too warm for your pets, too. Take the time to check on the temperature in your reptile’s enclosure and make adjustments as needed to keep them safe.
