The Revealing Signs That A Tortoise Is Stressed

Commonly known for their tranquility and docile nature, tortoises are typically composed and friendly animals, making them beloved pets worldwide. However, despite their usual serene demeanor, tortoises are not immune to stress and so it would do well to know the signs of a stressed tortoise. Unbeknownst to many, these endearing creatures can experience periods of anxiety and unease, with these feelings often amplified by improper or inadequate care, commonly referred to as poor husbandry. It’s critical to remember that tortoises, like any other pets, have specific needs, and neglecting these can lead to stress-related issues. While this might sound alarming, there’s a silver lining: problems stemming from poor husbandry can be identified, addressed, and corrected relatively easily. With proper knowledge, understanding, and attention, ensuring your tortoise’s well-being can become a straightforward and rewarding task.

Here’s a detailed table outlining the causes of stress in tortoises as well as some possible solutions:

Cause of StressDescriptionPossible Solutions
Change in EnvironmentTortoises are sensitive to changes in their surroundings, be it a new enclosure, relocation, or any drastic alterations in their habitat.Gradually acclimate the tortoise to the new environment, keeping changes subtle and slow. Provide familiar objects, like favorite hiding spots or toys.
Inadequate TemperatureImproper temperature levels, whether too hot or too cold, can cause discomfort and stress in tortoises.Maintain a suitable temperature gradient in the enclosure, closely mirroring the tortoise’s natural habitat. Use thermostatically controlled heaters.
Poor DietA diet lacking in essential nutrients or variety can lead to stress.Provide a varied and balanced diet rich in fiber and low in protein. Consult a vet for specific dietary advice.
Lack of Social Interaction or OvercrowdingBoth isolation and overcrowding can cause stress. Tortoises are solitary creatures, but they also need some level of interaction.Ensure that your tortoise has sufficient space and an appropriate level of social interaction. A solitary enclosure is often best for most species.
Improper LightingInadequate lighting, especially lack of UVB light, can lead to stress and health issues.Install appropriate UVB lighting in the enclosure and allow access to natural sunlight when possible.
Lack of Hiding PlacesLack of suitable hiding places can make a tortoise feel exposed and unsafe.Provide adequate hiding spots within the enclosure for the tortoise to retreat to when it feels the need.
Incorrect Humidity LevelsToo much or too little humidity can lead to discomfort and stress.Use a hygrometer to measure humidity levels and adjust as necessary to fit your tortoise’s species-specific needs.
Noise and VibrationsExcessive noise or vibrations can be stressful for tortoises.Place the tortoise’s enclosure in a quiet, low-traffic area. Avoid placing near appliances that create a lot of noise or vibrations.
Poor Health or IllnessHealth issues, whether chronic or acute, can cause significant stress in tortoises.Regular health check-ups with an exotic vet can help identify and treat any potential health issues early.
Glass EnclosuresTortoises can’t understand glass and may get stressed trying to walk through it.Use non-glass or frosted-glass enclosures, or cover the lower parts of the glass with opaque material so the tortoise doesn’t try to walk through it.
Insufficient SpaceA small enclosure can induce stress in a tortoise. They need space to roam around.Ensure the enclosure is large enough for the tortoise to walk around freely. An outdoor enclosure is beneficial if conditions permit.

How Do You Know if Your Tortoise is Stressed?

There are a number of signs a tortoise is stressed, but you should also be aware that some of these signs can also indicate an illness. It is important to be alert to the symptoms of illness and, if you are worried for the wellbeing of your reptileOpens in a new tab., speak to a vet for expert advice.


A tortoise that is stressed will spend a lot of time hiding. When a tortoise withdraws into its shell and will not protrude its legs or head, it is almost certainly caused by stress. If your tortoise is doing this, it is likely that it is finding something in its enclosure frightening. A move to a new home can result in acute episodes of stress, but these will usually subside within a week or two of arrival.


Lethargy is a common symptom of stress in tortoisesOpens in a new tab., but it can also a sign of illness. Identifying whether or not your tortoise is stressed or ill will mean looking at all of the signs and symptoms. Lethargy caused by illness will rarely be the only symptom. Look for other signs such as nasal discharge and labored breathing.

Loss of Appetite

As you might imagine, a stressed tortoise is unlikely to want to eat. Nevertheless, as with lethargy, a loss of appetite can often be one of the first signs of illness. As above, it is important to be alert to all the symptoms your tortoise is displaying and, if you are worried, contact a vet.

Social Interaction and Stress in Tortoises

In contrast to common belief, tortoises aren’t completely solitary animals. Although they do enjoy their quiet time, they can form attachments to their companions or owners, and a change in these dynamics can result in stress. To understand a tortoise’s social needs, you should consider their natural behavior in the wild. Many species of tortoises have territories and may interact with others during mating season, foraging, or when they cross paths in their habitats.

Adjusting to Changes in Social Environment

One of the most common causes of stress in tortoises can be an alteration in their social environment. For instance, the introduction of a new tortoise into their space can trigger a significant change in their behavior. They may feel threatened or anxious, which can manifest as changes in eating habits, lethargy, or increased aggression. It’s essential to monitor this transition closely to ensure both tortoises are adapting well to the change.

On the other hand, losing a companion can be equally distressing for a tortoise. If they’ve shared a space with another tortoise for a long time, the sudden absence can leave them feeling lonely and disoriented. It’s important to provide additional care and attention during this period, and closely monitor their behavior and overall health.

Balancing Interaction and Independence

Striking the right balance between social interaction and independence is key to reducing stress in tortoises. They don’t require constant companionship like some other pets, but occasional interaction can go a long way in keeping them healthy and stress-free. So, if you notice your tortoise is looking a bit off, take a moment to check their social conditions – are they alone too much, or perhaps, feeling crowded? A little adjustment might be all they need.

What Causes Stress in Tortoises

One of the biggest causes of stress in a tortoise is a change in environment. This typically happens when a tortoise is moved to a new home, whether that be when first purchased or if you are changing its enclosure to a new one. Obviously, this is something that cannot be helped, so if a move like this has caused stress in the tortoise then it is a good idea to keep things calm until your pet gets used to its new surroundings.

You can do this by keeping lights dimmed and temperature levels a bit higher. Make sure your tortoise is well hydrated and that the environment has the correct humidity levels. You may also want to consider giving your pet a short daily soak in warm water (as long as this is not causing additional stress).

Other causes of stress are:

  • insufficient lighting
  • incorrect temperature levels
  • poor diet
  • insufficient space
  • glass enclosure.

Impact of Noise and Vibration on Tortoise Stress

Tortoises, with their age-old wisdom and calm demeanor, are surprisingly sensitive creatures when it comes to their environment. Specifically, they can be greatly affected by the noise and vibration levels around them. Unlike many animals, tortoises do not have eardrums, but they are still capable of perceiving sound and vibrations. In the wild, the rustling of leaves or the gentle patter of rain are the usual sources of noise. That means they are not naturally equipped to handle the louder, more abrupt noises common in a typical human household, such as the hum of a refrigerator, the whirr of a washing machine, or the clamor from a television.

The Impact of Urban and Household Noises

Now, let’s talk about what happens when you introduce a tortoise into a bustling urban environment or a lively household. The excess noise, especially sudden sounds, can be startling for these peaceful animals, potentially triggering a stress response. A continually high noise level can make tortoises feel as if they’re in a permanent state of alert, leading to chronic stress. A similar response is often observed with high levels of vibration, such as those caused by traffic on a nearby road or construction work.

Signs of Stress from Noise and Vibration

How do you know if your tortoise is stressed by noise or vibration? You might observe changes in their behavior. They may retreat into their shell more often, or they could become lethargic and show less interest in food. They may also seem more anxious, continually attempting to escape their enclosure. Remember, these could also be signs of other health issues, so it’s important to consult with a veterinarian if you’re worried about your tortoise’s behavior.

Solutions to Minimize Noise and Vibration Stress

Fortunately, there are ways to reduce this source of stress for your tortoise. First, consider the location of their enclosure. If it’s currently in a high-traffic area of your home or near a street-facing window, you might want to move it to a quieter spot. Additionally, adding insulation to your tortoise’s enclosure can help buffer noise and vibrations. Consider a white noise machine to mask disruptive sounds, or use a carpet or rug under the enclosure to dampen vibrations. Simple adjustments can make a big difference in creating a peaceful, stress-free environment for your tortoise.


It is important that you have the temperature set for the species of tortoise you have. It is your job as a tortoise owner to ensure that you create an environment that is as close to your pet’s natural habitat as possible. You will need to establish a temperature gradient within the enclosure with both a warm and cool side. This allows the tortoise to move from one area to another when it gets too hot or too cold.

Quick Tip: Look to have the warm side (under the basking light) set between 86-90oF while the cooler side can be between 68-75oF. Some species may also require night time heating of about 60oF.


You will also need to ensure humidity levels are correct. Tortoises that hail from arid parts of the world will require lower humidity levels than those that come from more humid areas.


Lighting is also important. Remember that most tortoise species hail from parts of the world where there is a lot of sunlight. They need this light to help with digestion and to generally stay healthy. Unless you live in a warm sunny part of the world and your tortoise has an outdoor enclosure, you will need to provide artificial UV light.

Your tortoise will need at least eight to ten hours of UV light per day. Without UV lighting, the tortoise will be unable to synthesize vitamin D3, which is required for the absorption of calcium. Calcium is vital for the tortoise’s growth and bone structure. As well as this, without it your tortoise could develop metabolic bone disease (MBD). Tortoises with MBD will struggle to walk and will suffer bone pain.

When it comes to diet, variety is important. Your tortoise’s diet should comprise mostly vegetables such as mustard, dandelion, chicory, and clover. You can grow your own from seeds to ensure you have a constant supply. Tortoises can also eatOpens in a new tab. things like bell peppers, cauliflower, and sweet potato.

Quick Tip: If you are giving your tortoise fruits, be sure that these only make up around five to ten percent of its diet. Fruits such as kiwi, melon and berries are suitable. As fruit contains a lot of sugar, it is best to limit it to a couple of times per week.  

Vitamin supplements are also important for your tortoise. Calcium and vitamin A supplements can be purchased from your local reptile store or online and sprinkled over the food you provide.

I have already mentioned that a move to a new enclosure could be causing stress in your tortoise, but there are other issues in relation to enclosures that need to be considered. For example, you might not be aware, but a glass enclosure could be the cause of stress in your tortoise. Tortoises just don’t ‘get’ glass. They can see through it, but they cannot understand why they cannot walk through it. Some will butt their head against the glass or continually try to climb the wallsOpens in a new tab. in a bid to get out. Therefore, it is better to have a wooden enclosure.

A lack of space can also induce stress in a tortoise. These creatures walk for miles in their natural habitats looking for food; if they are penned into an area that is too small, they could become stressed.

Mitigating Stress: Handling and Interaction Techniques

Every tortoise, like any other pet, requires thoughtful, gentle handling and positive interaction methods to build trust and minimize stress. Remember, their wild counterparts lead solitary lives, only interacting during mating season. So, it’s essential to approach them with care.

When it comes to handling your tortoise, remember these important points. Always handle your tortoise gently and with clean hands to minimize the risk of transmitting harmful bacteria. Approach the tortoise from the front so that they can see you. Sudden movements from above or behind can startle them, which can heighten stress. Keep handling sessions brief and infrequent; tortoises are not like dogs or cats and may find excessive physical contact stressful.

It is also key to closely observe your tortoise’s reaction during these interactions. If they seem to pull into their shell or move away from you more frequently during handling sessions, they may be signaling discomfort or stress, suggesting that you should limit handling.

Positive interaction with your tortoise isn’t limited to physical handling, though. You can also interact positively by maintaining a stimulating and comfortable environment. For example, you might occasionally rearrange their enclosure’s layout, adding new hideaways or climbing materials to explore, always ensuring that changes are subtle and not disruptive.

Feeding can also be a great time for interaction. You could hand-feed a favorite food now and then, promoting a positive association with your presence. But remember to watch for signs of stress during feeding sessions, too, and if you notice any, try placing their food in the enclosure and withdrawing, giving them space.

Finally, speak softly around your tortoise. Although they don’t understand our words, the soothing tone of your voice can have a calming effect, as they’re sensitive to vibrations in their environment.

Stress and Reproductive Health

It’s important to understand that tortoises, much like any other living creature, are susceptible to the pressures of their environment, and these pressures can directly impact their ability to breed. When a tortoise experiences stress, it triggers a physiological response that can disrupt their reproductive system. The body, in an attempt to survive, may deem reproduction as non-essential, thus delaying or even halting the process altogether.

Stressors and Their Effects

Various stressors can lead to such a condition, including changes in environment, inappropriate temperatures, inadequate diet, or a lack of privacy during the breeding season. Females, in particular, may be prone to withholding eggs if they feel stressed or unsafe, a condition known as ‘egg-binding.’ This is a serious health concern and requires immediate veterinary attention. On the other hand, male tortoises may exhibit decreased libido and mating behaviors when stressed, making successful breeding difficult.

Stress Management for Healthy Breeding

Successful breeding requires more than just bringing a pair of tortoises together. Owners must strive to create a conducive, stress-free environment for the tortoises, carefully monitor their health, and ensure that their nutritional needs are met. It’s also important to provide a suitable nesting area for females to lay their eggs, which can contribute to reducing stress levels during the breeding season. By managing stress effectively, owners can help improve their tortoises’ reproductive health and increase the chances of successful breeding.

Remember, it’s always crucial to consult with a reptile vet or a tortoise breeding expert if you have any concerns about your tortoise’s health or reproductive behavior. They can provide guidance and treatment options based on their extensive knowledge and experience.

Health Implications of Chronic Stress in Tortoises

Chronic stress in tortoises, much like in humans, has the potential to precipitate a number of serious health problems that can compromise their overall wellbeing.

Compromised Immune System

Firstly, let’s address the elephant in the room – a compromised immune system. When a tortoise is subjected to chronic stress, the biological response can result in a sustained production of stress hormones, primarily cortisol. This hormonal imbalance can weaken the tortoise’s immune system, making it less capable of fighting off infections. A weakened immune system may result in the tortoise being more susceptible to a range of diseases, from common colds to more serious health issues, such as respiratory infections and metabolic bone diseaseOpens in a new tab..

Increased Susceptibility to Diseases

Chronic stress not only paves the way for infections to take root, but it can also exacerbate pre-existing health conditions. The body’s physiological response to prolonged stress often leads to poor digestion and nutrient absorption, impacting the tortoise’s overall health and wellness. It’s important to note that a poorly functioning digestive system could lead to vitamin and mineral deficiencies, such as calcium deficiency, which can further complicate the tortoise’s health.

Mental Health

Moreover, let’s not overlook the mental health aspect. Continuous stress can significantly alter a tortoise’s behavior, causing it to be less active, interactive or responsive to its surroundings. This might manifest in the form of excessive hiding, lethargy, or loss of appetite, severely affecting the tortoise’s quality of life.

Post-Stress Rehabilitation

The recovery phase after a stressful event is crucial in a tortoise’s life. It’s not just about waiting for the stress to fade away; active steps need to be taken to ensure the tortoise is back in its comfortable state.

Firstly, re-evaluating and adjusting the environment plays a significant role. Make sure the enclosure reflects the natural habitat of your tortoise as closely as possible. If the stress was caused by a change in the environment, revert to the original conditions, if practical. Always ensure the lighting, temperature, and humidity levels are appropriate for the tortoise’s species. Keep noise levels to a minimum and consider introducing natural elements, such as plants and hiding places, to make the environment more friendly.

Diet Adjustments

Post-stress, a tortoise’s diet should be closely monitored. As eating habits often change when a tortoise is under stress, gently reintroducing its favorite foods can be a good strategy. A varied diet, rich in nutrients, can boost their overall health. Provide a range of leafy greens, vegetables, and fruits (limited to 5-10% of the diet). Consider adding a multivitamin or calcium supplement to ensure the tortoise gets all the nutrients it needs. Always consult with a vet or an expert before making significant changes to your tortoise’s diet.

Vet Consultations

While stress is something that can be managed at home to a large extent, if your tortoise has been under chronic stress, it’s important to seek advice from a professional exotic vet. They can perform health checks and provide treatments if necessary. Vets can also suggest preventative measures and provide guidance on improving the living conditions of your tortoise. Regular health checks can be beneficial, as they can help detect any possible health issues at an early stage, which might be causing or exacerbating the stress.

Signs of a Stressed Tortoise – Conclusion

Stress is not uncommon in tortoises but can usually be rectified by looking at the environment in which it is kept. However, as many of the symptoms of stress are similar to those caused by illness, it is important to be aware of the signs of common illnesses such as respiratory disease and pneumonia.

I suggest that if your tortoise is displaying signs that are out of the ordinary, you first look at temperature, lighting, and humidity levels to ensure these are at correct levels. If the tortoise’s behavior continues to worry you, it would be prudent to seek advice from a professional exotic vet.
