Third eyelid in cats – What can you do to stop showing them

Introduction

Definition of third eyelid in cats

Cats have a third eyelid, also known as the nictitating membrane. It is located in the inner corner of their eyes. Unlike the upper and lower eyelids, the third eyelid in cats moves horizontally across the eye. They provide an additional layer of protection and lubrication. This membrane also contains a gland that produces approximately one-third of the tears needed to lubricate the eyes.

Importance of understanding why a cat's third eyelid may be showing

It’s important for cat owners to understand why their cat’s third eyelid may be showing. It can be a sign of an underlying health issue. Some instances of third eyelid showing in cats may be minor and resolve on their own. Others can be an indication of a more serious condition that requires prompt veterinary attention. Additionally, knowing how to recognize and treat third eyelid showing can help prevent potential complications. This will ensure that your cat remains healthy and happy.

Anatomy of the Cat Eye

Basic structure of the cat eye

The cat eye is a complex structure designed to help them see in various light conditions. The eye is made up of several parts, including the cornea, iris, pupil, lens, retina, optic nerve, and eyelids. The cornea and lens focus light onto the retina. This retina contains specialized cells that convert light into electrical signals that are sent to the brain for processing.

The role of the third eyelid in eye health

The third eyelid in cats plays an important role in maintaining eye health in cats. It provides an additional layer of protection for the eye, helping to keep it moist and free of debris. The membrane also contains a gland that produces tears. These tears help to lubricate the eye and wash away any foreign particles.

Differences in the appearance of the third eyelid in cats

The appearance of the third eyelid in cats can vary. In some cats, the third eyelid may be barely visible. While in others it may be more prominent. Additionally, the third eyelid may appear to be raised or swollen in cats with certain eye conditions or health issues. It’s important to be familiar with the normal appearance of your cat’s third eyelid. This way you can recognize any changes that may indicate a problem.

Home Treatment for Third Eyelid in Cats Showing

In many cases, a cat’s third eyelid showing can be a minor issue. In this case it can be resolved with some basic home treatment. Here are some tips for treating the third eyelid in cats at home:

Tips for home treatment:
      • Keep the eye clean: Use a damp, clean cloth to gently wipe away any discharge or debris around the eye. Make sure to use a fresh part of the cloth for each wipe. Gauze pads come in very handy. 

      • Use eyedrops to lubricate the eye and flush out any debris that is causing the irritation of the eye. Like the one below for example. 
      • If the third eyelid is red then it is inflamed. Use the following eye drops to stop the infection twice a day. Stop using when the eyelid has returned to it’s normal position for 3 days. Do not stop sooner. 
      • Provide supportive care: Keep your cat comfortable by providing them with a warm, quiet space to rest in. You may also consider providing a soft bed or blanket for them to lay on.

      • Offer plenty of fluids: Encourage your cat to drink plenty of water to help keep them hydrated.

      • Make sure they eat a bit during the day. For cats it is very important to eat at least a third of the normal amount of food. Otherwise the liver may be damaged, causing them to die. Use warm, moist food for cats. And use a syringe if they don’t want to eat. 
      • Monitor their behavior: Keep an eye on your cat’s behavior. If they seem lethargic, it may be a sign of a more serious underlying condition.

When to seek veterinary attention:

Home treatment can be effective for mild cases of showing third eyelid in cats. But it is important to seek veterinary attention if your cat is feeling awful. Also seek care if you are in doubt about:

      • The third eyelid in cats is showing in one eye only: This may indicate an injury or infection in the affected eye.

      • The third eyelid in cats is swollen or red: This may be a sign of infection or inflammation.

      • The third eyelid is protruding or visible all the time: This may indicate a more serious underlying condition. Such as haws syndrome or a tumor.

      • Your cat is showing other symptoms such as fever, lethargy, or loss of appetite: These symptoms may indicate an underlying illness or infection that requires medical attention.

It is important to remember that cats are skilled at hiding pain and discomfort. Do you notice any changes in your cat’s behaviour or appearance? In that case it is always best to consult with a veterinarian to ensure their health and wellbeing.
