Cats, by nature, are very clean animals and they spend a significant time of their day cleaning themselves. This means that, in most cases, signs of significant brown discharge in your cat’s eyes or what we would describe as “eye boogers” or “eye gunk” is usually not normal.
5 common causes of cat eye discharge
Although rare, eye discharge in cats can be seen and is frequently associated with the following problems:
- Problems with the eyelids and conformation of the face. Purebred cats, particularly exotic breeds, are known to suffer from eye problems among which is entropion. This can lead to irritation of the eyes and eye discharge which can in most cases appear brown or reddish-brown around the middle corner of the eye.
- Underlying eye infections. Infections with bacteria, which can complicate an existing ulcer, are a common cause of eye discharge in cats.
- Viral causes. One of the most common reasons leading to eye discharge in cats is underlying viral infections, with the most common one being feline herpes virus (FHV-1). The discharge seen in a cat’s eye can range from clear, to brown or reddish-brown.
- Allergies or conditions of the immune system. Food or environmental allergies and certain conditions of the immune system which usually affect the skin can involve the skin of the eyelids and lead to eye problems and eye discharge.
- Mites and parasites. When the appropriate preventative antiparasitic treatment is used (as advised by your vets) on a monthly basis, this should not be a concern. However, newly rehomed cats and especially those who might have previously been stray cats, can often suffer from skin parasites that can affect the eyelids and lead to irritation of the skin. This subsequently leads to eye discharge.
What are the signs of eye discharge in cats?
Stuck brown discharge at the middle corner of the eye(s), swollen or reddened eyelids, accumulation of “gunk” or yellow discharge in the eyes and keeping their eyes shut are some of the most common signs we see in cats suffering from problems.
Some cats might over groom their face in response to the problem and cause injuries or scabbing of the skin or even pull out the hairs around the eyelids.
Treatment options for eye discharge and when to seek veterinary care
As previously mentioned, cats are very clean pets and signs of discharge should not be ignored.
Using cooled boiled down water to gently clean the skin of the eyelids is recommended, especially if your cat is struggling to open their eyes due to the amount of discharge.
However, you should seek urgent advice from your vets if the problem persists for more than 24 hours.
