Eye discharge in cats can be indicative of several factors, including infections, allergies, or injuries. When the discharge takes on a brown hue, it often points to something beyond normal tear staining. While not all cases are cause for immediate alarm, it’s essential to investigate the cause of the brown discharge and ensure your cat receives appropriate care.

Brown Eye Discharge: Possible Causes

**1. Epiphora:

Epiphora refers to excessive tearing or watering of the eyes. It can be caused by various factors, including eye irritations, allergies, or blocked tear ducts. When the tears mix with the natural secretions around the eyes, they can create brownish stains.

**2. Eye Infections:

Eye infections, such as conjunctivitis or bacterial infections, can lead to brown eye discharge. The discharge might also be accompanied by redness, swelling, and discomfort.

**3. Corneal Ulcers:

Corneal ulcers are open sores on the surface of the eye. They can cause watery eyes, squinting, and brown discharge. Corneal ulcers require immediate veterinary attention to prevent complications.

**4. Glaucoma:

Glaucoma is a condition that increases pressure within the eye, leading to discomfort and potential vision loss. It can cause excessive tearing and cloudy, brownish discharge.

**5. Foreign Objects or Injuries:

Foreign objects like dirt, debris, or small particles can get trapped in the eye, leading to irritation and tearing. Injuries to the eye can also cause similar symptoms.

**6. Conjunctival Hyperemia:

Conjunctival hyperemia is an inflammation of the blood vessels in the eye’s conjunctiva. It can lead to redness, watery eyes, and brownish discharge.

When to Worry About Cat’s Eye Discharge

While some cases of eye discharge might resolve on their own, there are situations that warrant immediate attention:

  • Persistent Discharge: If the brown eye discharge persists for more than a day or worsens, it’s crucial to consult a veterinarian.
  • Change in Behavior: If your cat is excessively rubbing its eyes, squinting, or showing signs of discomfort, it indicates a problem.
  • Cloudiness or Redness: Cloudiness in the eye or redness around the eye area could signify an underlying issue.
  • Change in Appetite or Behavior: Any noticeable changes in your cat’s behavior, appetite, or activity levels should be taken seriously.
