Cats, like many other animals, have a unique anatomy that includes a third eyelid, also known as the nictitating membrane or haw. This thin, translucent eyelid is located in the corner of the eye and plays a crucial role in protecting and keeping the eye clean. However, when a cat’s third eyelid is visible, it can be a cause for concern among pet owners. One common question that arises is whether stress can cause a cat’s third eyelid to show. In this article, we will delve into the world of feline anatomy and behavior to explore the relationship between stress and the third eyelid, and what it might mean for your cat’s health.
Understanding the Third Eyelid
The third eyelid is a remarkable feature that serves several purposes. It helps to protect the eye from debris and dust, keeping it clean and clear. When a cat blinks, the third eyelid moves across the eye, spreading tears and keeping the eye moist. It also contains glands that produce a special type of mucus that helps to trap foreign particles and keep the eye healthy. In normal circumstances, the third eyelid is not visible, and it only becomes apparent when it is elevated or protruding.
Anatomy of the Third Eyelid
The third eyelid is made up of a thin membrane that is attached to the eye by a small bone called the nictitating cartilage. The membrane itself is composed of a layer of tissue that contains blood vessels, nerve endings, and glands. The third eyelid is normally retracted and hidden from view, only becoming visible when the cat is asleep, relaxed, or experiencing a health issue. When the third eyelid is visible, it can be a sign of illness, injury, or stress, and it is essential to investigate the underlying cause.
Stress and the Third Eyelid
Stress can have a significant impact on a cat’s behavior and physiology, and it is possible that stress can cause a cat’s third eyelid to show. When a cat is stressed, its body undergoes a range of physical changes, including increased heart rate, blood pressure, and respiration. Stress can also affect the nervous system, leading to changes in behavior, appetite, and overall health. In some cases, stress can cause the third eyelid to become elevated or protruding, making it visible to the owner.
Causes of Stress in Cats
Cats can experience stress due to a variety of factors, including changes in their environment, social stress, and health issues. Some common causes of stress in cats include:
- Changes in the household, such as a new pet or family member
- Moving to a new home or environment
- Loud noises or crowds
- Lack of attention or social interaction
- Underlying health issues, such as pain or discomfort
Recognizing Stress in Cats
Recognizing stress in cats can be challenging, as they often hide their emotions and physical discomfort. However, there are some common signs of stress in cats that owners should be aware of, including:
- Changes in appetite or sleep patterns
- Pacing, hiding, or avoidance behavior
- Excessive grooming or licking
- Increased vocalization or meowing

Diagnosing the Underlying Cause
If you notice that your cat’s third eyelid is visible, it is essential to consult with a veterinarian to determine the underlying cause. The veterinarian will perform a physical examination and take a complete medical history to identify any potential health issues. They may also perform diagnostic tests, such as blood work, urinalysis, or imaging studies, to rule out underlying medical conditions.
Treatment and Management
The treatment and management of a visible third eyelid will depend on the underlying cause. In some cases, medication or surgery may be necessary to address the underlying health issue. In other cases, lifestyle changes or environmental modifications may be recommended to reduce stress and promote overall health. It is essential to work closely with a veterinarian to develop a treatment plan that addresses the underlying cause and promotes the cat’s overall well-being.
Conclusion
In conclusion, stress can cause a cat’s third eyelid to show, but it is not the only possible explanation. A visible third eyelid can be a sign of underlying health issues, and it is essential to consult with a veterinarian to determine the cause. By understanding the anatomy and function of the third eyelid, recognizing the signs of stress in cats, and seeking veterinary care when necessary, owners can help promote their cat’s overall health and well-being. Remember, a healthy and happy cat is a cat with a clean bill of health and a low-stress environment. By providing a nurturing and supportive home, you can help your cat thrive and reduce the risk of stress-related health issues.
What is the third eyelid in cats, and what is its function?
The third eyelid, also known as the nictitating membrane, is a thin, translucent tissue located in the inner corner of a cat’s eye. It is an essential feature that serves several purposes, including protecting the eye from debris, providing extra lubrication, and aiding in the removal of foreign particles. When a cat is healthy and relaxed, the third eyelid is not usually visible, as it is tucked away in the corner of the eye. However, when a cat is stressed, ill, or experiencing eye problems, the third eyelid may become visible, which can be a cause for concern for cat owners.
The third eyelid is made up of a thin layer of tissue that contains blood vessels, lymphatic vessels, and a few glands that produce a small amount of tears. In normal circumstances, the third eyelid moves slowly across the eye to help remove dirt and dust, and it also helps to distribute tears evenly across the eye. When a cat is under stress, the third eyelid may become more prominent due to the release of stress hormones, such as adrenaline, which can cause the blood vessels in the third eyelid to constrict, making it more visible. Additionally, stress can also lead to a decrease in tear production, which can cause the third eyelid to become more noticeable as it tries to compensate for the lack of moisture in the eye.
How does stress affect a cat’s third eyelid, and what are the signs to look out for?
Stress can have a significant impact on a cat’s third eyelid, causing it to become more visible and prominent. When a cat is under stress, its body releases stress hormones, such as cortisol and adrenaline, which can cause a range of physiological changes, including an increase in heart rate, blood pressure, and respiration. One of the signs of stress in cats is the showing of the third eyelid, which can be a subtle but important indicator of a cat’s emotional state. Other signs of stress in cats may include changes in appetite, sleep patterns, and behavior, such as pacing, meowing, or hiding.
If you notice that your cat’s third eyelid is showing, it is essential to look out for other signs of stress and to try to identify the underlying cause of the stress. This can be a challenging task, as cats are often skilled at hiding their stress and anxiety. However, by paying close attention to your cat’s behavior and body language, you may be able to identify potential stressors, such as changes in the home environment, the presence of other pets, or underlying medical issues. By addressing these stressors and providing a calm and supportive environment, you can help to reduce your cat’s stress levels and minimize the visibility of the third eyelid.
