  • Often caused by dust, dirty bedding, scratches or bacteria.
  • Can range from mild irritation to severe, painful swelling.

  • Early care helps prevent permanent eye damage.

Why Does My Hamster Get Eye Infections?

Hamster eye infections usually begin when something irritates the eye, such as dust from bedding, sharp food particles or even fighting injuries. Once the eye is irritated, bacteria or fungi can infect the area. Poor cage hygiene, vitamin deficiencies or immune weakness also make eye infections more likely.

Types of Hamster Eye Infections

Conjunctivitis
(Pink Eye)

The most common type of hamster eye infection. The tissue around the eye becomes inflamed, red and swollen.

Often linked to bacteria, viruses or even allergic reactions to bedding. Discharge may start watery but quickly turn thick and sticky.

Corneal Injury and Infection

If the clear surface of the eye gets scratched, by sharp bedding, food particles, or fighting, it can allow bacteria to enter.

The eye may turn cloudy or bluish and be very painful. Without treatment, ulcers can form, leading to partial vision loss.

Abscess Behind the Eye

A deep bacterial infection behind the eye that causes bulging, severe swelling and sometimes loss of movement in the eye. Hamsters with abscesses often stop eating due to pain. This type is serious and requires urgent veterinary care.

Secondary Eye Infection from Respiratory Illness

Respiratory infections like flu or pneumonia can spread to the eyes, causing watery, red eyes along with sneezing and nasal discharge.

Symptoms of Hamster Eye Infections

Redness and Swelling

The eyelids and tissue around the eyes look sore, red and puffy. This is often the first sign owners notice.

Cloudy or Hazy Eyes

The eye surface becomes foggy, bluish, or whitish. This indicates corneal damage or deep infection, which can affect vision.

Constant Pawing or Face Rubbing

Hamsters scratch or rub their eyes on cage bars or bedding because of irritation. This often makes the condition worse.

Vision Trouble

Advanced infections may cause partial blindness. Hamsters may bump into cage walls or hesitate before climbing or moving around.

Watery, Sticky, or Pus-like Discharge

Mild cases produce clear tears, but infections usually lead to yellow, green or brown discharge. Crust may dry on the eyelids, gluing them shut.

Crust and Fur Matting Around Eyes

Discharge may stick to surrounding fur, making the area dirty and uncomfortable. Severe cases may cause fur loss around the eyes.

Squinting or Keeping One Eye Shut

Painful eyes make hamsters squint or close the affected eye completely.

Hamster Eye Infection FAQ

Most hamster eye infections are caused by dust, dirty cages or small injuries. Bacteria or fungi then take advantage of the irritation.

No. While mild cases may improve slightly, most infections worsen without treatment and can cause blindness.

 

Look for redness, swelling, discharge, or your hamster keeping one eye shut. Pawing at the face and changes in behavior are also common.

Some infections, especially bacterial ones, can spread to other hamsters. Keeping cages clean and separating sick hamsters is important.

 

Veterinarians may prescribe eye drops, oral medication, or in severe cases, surgery. Cleaning and good hygiene are also part of recovery. Go to your nearest vet for treatment.
