Why is cat closing one eye?

Answered by Paul Bowser

If you notice that your cat is closing one eye, it may be a sign of pain or discomfort in that eye. Cats are known for their ability to hide signs of pain, so it’s important to pay attention to any changes in their behavior or appearance. Here are some possible reasons why your cat may be closing one eye:

1. Eye injury: Cats can injure their eyes through various means, such as scratches from other animals, foreign objects getting into the eye, or trauma from accidents. If your cat has closed one eye after a potential injury, it could be a protective reflex to reduce irritation or pain.

2. Conjunctivitis: Conjunctivitis, also known as pink eye, is a common eye infection in cats. It can cause redness, discharge, and inflammation, leading to discomfort and the cat closing one eye. If you notice any discharge or redness in the affected eye, it’s crucial to consult with your vet for proper diagnosis and treatment.

3. Corneal ulcers: Corneal ulcers are painful sores on the surface of the eye. They can occur due to trauma, foreign objects, or infections. Cats with corneal ulcers often close the affected eye to protect it from further damage and reduce pain.

4. Eye infections: Various bacterial, viral, or fungal infections can affect a cat’s eye, causing discomfort and leading to the cat closing one eye. Symptoms may include redness, discharge, swelling, or cloudiness. It’s essential to consult with a vet to determine the underlying cause and appropriate treatment.

5. Glaucoma: Glaucoma is a condition characterized by increased pressure within the eye, leading to pain and potential vision loss. Cats with glaucoma may close one eye due to the discomfort caused by the increased pressure. Other signs may include dilated pupils, cloudiness, and a change in the eye’s appearance. Glaucoma requires immediate veterinary attention.

6. Foreign object: If a foreign object, such as a small particle or dust, gets into your cat’s eye, it can cause irritation and pain. Your cat may react by closing the affected eye to minimize discomfort and protect the eye from further damage. If you suspect a foreign object in your cat’s eye, it’s important to seek veterinary assistance.

Remember, these are just a few possible explanations for why your cat may be closing one eye. It’s crucial to consult with your vet to determine the exact cause and appropriate treatment. They may need to perform a thorough examination, including an eye examination, to diagnose the underlying issue accurately.

As a sommelier and brewer, I have not personally encountered this specific issue with cats, but I do understand the importance of seeking professional advice when it comes to any health concerns for our furry friends. Animals cannot communicate their pain or discomfort in the same way humans can, so it’s crucial to pay attention to any changes in their behavior and seek veterinary assistance promptly.
