Eye infections are very common in cats!

In young cats infections are often caused by bacteria or viruses.


Chlamydia and Mycoplasma are the bacteria most commonly diagnosed and the Feline Herpes virus Type 1 is the most common virus that affects the eyes.

In older cats an eye infection can be a symptom of a more serious underlying problem including systemic viral infections like feline leukemia (FeLV) and feline immunodeficiency virus (FIV) also autoimmune disease and cancer.


  • Blinking or rubbing the eyes
  • Redness in the whites of the eyes
  • Runny clear, yellow or green discharge
  • The third eyelid protruding and covering part of the eye
  • Sneezing or nasal discharge

Your cat may show one, several or all of the symptoms above.  If the eye shows any sign of damage, it is of paramount importance that you visit your vet immediately.  If the eye starts to close up and your cat will not open it; GO TO THE VET!

Remember our furry friends can’t tell us what’s wrong and unlike humans to don’t whinge and complain but that does not mean they are not suffering and its our duty as caring pet owners to keep an eye out for any symptoms that may arise.  Eye Infections In Cats may in some cases be the first signs of another more serious underlying problem


For an accurate diagnosis it is important to take your cat to the Vet who can take a swab of the infected area and have a look for any infectious bacteria or viral infection. If the veterinarian suspects an underlying problem they may recommend blood tests.


Bacterial infections are predominantly treated with antibiotics normally in the form of eye drops. Viral infections however, usually clear up on their own but your vet may recommend an antiviral medication.
