Feline Entropion

Entropion is a condition in cats, associated with one or both eyelids turning inward into their eyes. This condition can cause irritation and discomfort to the cat and can even lead to sight loss if not treated promptly. Common causes of entropion include genetic predisposition, trauma, or inflammation due to infection.

Symptoms of Feline Entropion

One of the most common symptoms of feline entropion is excessive tearing and discharge from the affected eye. In some cases, there can also be a visible inward turning of one or both their eyelids. Other signs can include:

  • Squinting
  • Swelling
  • Inflammation
  • Redness
  • Crusting around their eyes

If left untreated, entropion can cause severe ulceration and corneal damage.

Diagnosing Feline Entropion

Diagnosing feline entropion is not too difficult because the symptoms are quite different from other eye conditions. Your veterinarian will likely have a look at your cat’s eyes and can also take a sample of any discharge for laboratory testing. In more severe cases, an ophthalmologist might need to be consulted.

Stages of Feline Entropion

Feline entropion is typically split into three stages: mild, moderate, and severe


In the mild stage, their eyelid can be slightly inverted but there are no signs of discomfort or irritation.


During the moderate stage, their eyelid has a more pronounced inward turning and can cause redness, swelling, and discharge from their eye.


In severe cases, their eyelid is completely inverted and there is significant pain, swelling, and corneal damage.

Treating Feline Entropion

The most common treatment for feline entropion is surgery. This procedure involves removing the inverted portion of their eyelid and then suturing it back into place. Depending on the severity of their condition, a simple outpatient procedure might be performed or more complex surgery could be required.

Preventing Feline Entropion

The best way to prevent entropion in your cats is to ensure they are properly vaccinated and don’t suffer from any underlying conditions that could cause the condition. 

It’s important to keep your cat’s environment clean and free of irritants or allergens that could cause inflammation. Finally, regular eye exams by a veterinarian can help catch entropion early, before it causes serious damage.
