Purulent Discharge in Cats: Causes and Symptoms

One of the most vulnerable organs in animals is the eyes. In them, as in a mirror, the state of health of a pet is reflected. The fact that the body develops pathology, can say discharge from the eyes. At the same time, you need to understand that there is a difference between the usual dry crusts that appear in the pet after waking up and purulent discharge.


Festering eyes are not an independent disease, but just a symptom, and veterinarians identify many of its causes.

One of the most common — ophthalmic pathologies:

  1. Conjunctivitis is a non-dangerous disease that is an inflammation of the mucous membrane of the eyes.
  2. Keratitis is a corneal lesion caused by injuries, chemical burns, infections, and allergies.
  3. Blepharitis is an inflammation of the edges of the eyelids caused by bacteria.
  4. Injury of the mucosa. Minor damage is delayed in an independent manner. In large wounds caused by sharp objects (claws, branches), an inflammatory process may occur with suppuration of the eyes.

Often kittens are born with pathologies of the visual organ. Defects cause lacrimation and pus discharge. So, the baby may not have a tear point, the lower eyelid is wrapped in the inner side, the eyelashes grow in several rows, and so on. For different reasons, causing suppuration, are:

  • poor quality care, lack of hygiene;
  • an unbalanced diet;
  • reduced immunity;
  • colds caused by drafts and hypothermia;
  • allergies;
  • atopic dermatitis;
  • chlamydia;
  • heredity.

Eyes can fester in any animal, regardless of gender and age. Especially susceptible to this pathology are breeds such as Scottish, British, and Persian. This is due to the anatomical features of the skull.


It is impossible not to notice that the cat’s eyes are suppurating. As a rule, suppuration is accompanied by other signs. Cats are very clean, so they give them a lot of discomfort. The animal often blinks, constantly rubs its muzzle, trying to get rid of dried crusts.

The eyes become red, swollen, watery, and discharge yellow, green, or brown pus. Wool near the eyelids darkens, a dense crust forms around them, preventing the cat from opening them completely.

Previously active and cheerful pet becomes sluggish, apathetic, refuses to eat, tries to hide in a dark place, away from the light. In some cases, the temperature rises.

If you notice purulent discharge in your four-legged pet, you should immediately contact the veterinarian. If this is not possible, then you need to wash your eyes, but then show the animal to a specialist.


First, the doctor examines the animal for injuries, collects information about its health status, and finds out what chronic diseases are present. Further, to make a diagnosis, the veterinarian needs to conduct a number of diagnostic studies, including the study of the frequency and consistency of secretions.

In some cases, it is necessary to conduct an ultrasound examination of the affected eye and x-ray of the skull.

Treatment, prognosis

There is no single treatment for purulent eyes in cats. The veterinarian develops an individual scheme depending on the disease, with the elimination of which the problem of purulent discharge will disappear.

Be sure to prescribe eye drops and ointments, which are divided into three groups:

  1. Antiseptic (bactericidal). The composition includes polysept, anesthetic and other components that help eliminate pain. The most effective are such drugs as Oftalmica, Larrikan.
  2. Antibacterial. Indicated for bacterial infections. Ciprovet, Decta-2, and Lacrimine aseptic have proven themselves well. They relieve inflammation and successfully treat chronic diseases of the visual organs.
  3. Immunomodulatory. They are prescribed for inflammatory processes and viral infections. As a rule, the veterinarian prescribes Anandine and Maxidine. They strengthen the immune system, accelerate wound healing, and inhibit the activity of viruses.

The medicine and dosage are set by the veterinarian. Before laying the ointment or instilling drops, the eyes should be cleaned of pus and crusts with a disinfectant solution.

Congenital anomalies are eliminated surgically.

What to do at home

The owner must follow the instructions of the veterinarian. Self-medication is dangerous and can worsen the situation.

You can wash the cat’s eyes with a decoction of chamomile, a solution of boric acid, furatsilina. The pet is unlikely to accept this manipulation with enthusiasm, so it is advisable to perform the procedure together: one person holds the cat, the second treats his eyes, and then instills the drug.

The solution used must be warm. Washing is carried out with a cotton pad, twisted with a tourniquet, until the pus from the eye is completely removed. Only after this, the drug is applied.

Do not use a dry disk or cotton swabs, as they can injure the visual organs.

Prevention measures

Any disease can be prevented, and ophthalmic pathologies are no exception. To detect the disease in time, you need to regularly examine the eyes, and contact a specialist at the first symptoms. It is impossible to ignore the fact of purulent discharge, because the disease can take a chronic form and it will be more difficult to cure it.

Measures for the prevention of eye diseases include compliance with hygiene requirements, proper care, balanced nutrition, the use of anthelmintic drugs, injury prevention, and restriction of contact with stray animals.

If the pet is scratched in the eye area, the wound should be treated immediately to prevent infection. It should not be allowed to comb the damaged area.
