Hamster Eye Problems: Sticky Eye, Infections, and Cataracts

Common Eye Conditions in Hamsters

Hamsters are prone to several eye conditions. Sticky eye is common in young hamsters and older hamsters — the eyelids become sealed shut with dried discharge. This is often secondary to an upper respiratory infection or environmental irritants (dusty bedding). Eye infections (conjunctivitis) cause redness, discharge, and squinting. Cataracts (clouding of the lens) are common in older hamsters and develop rapidly in diabetic hamsters. Exophthalmos (bulging eye) can result from abscesses behind the eye, dental problems, or trauma.

First 3 Steps to Take at Home

1. Gently clean sealed eyelids: For sticky eye, soak a cotton ball in warm water and hold gently against the sealed eye for 30–60 seconds. The dried discharge softens and the eye can often be gently opened. Repeat 2–3 times daily. If the eye doesn't open or there's obvious discharge inside, veterinary eye medication is needed.
2. Assess the eye once open: Is the eye clear or cloudy? Is there ongoing discharge? Is the hamster squinting? A clean, open eye after treatment may need only continued gentle cleaning. Persistent discharge or cloudiness requires veterinary eye medication.
3. Review the bedding: Dusty or fine-particle bedding (cedar shavings, pine shavings, dusty paper bedding) causes eye irritation that leads to sticky eye. Switch to dust-extracted or larger-particle bedding.

When to Go to the Vet Immediately

• Eye that cannot be opened despite gentle warm water treatment
• Visibly bulging or swollen eye
• Cloudy eye in a young hamster (not expected at a young age)
• Eye discharge that is yellow or green

Follow-Up Care Checklist

• Apply prescribed eye drops at the correct frequency — timing matters for eye treatment
• Switch to dust-free, paper-based bedding to reduce recurrence
• For diabetic cataracts: manage blood sugar as the primary intervention

Book a Vet Appointment

Any eye condition that doesn't resolve with gentle cleaning within 24–48 hours needs veterinary eye medication. Book at Happy Paws for eye assessment.

Summary for Your Clinic Visit

Describe the eye condition (sealed, cloudy, bulging, discharging), how long it's been present, the current bedding type, and whether the hamster is showing other symptoms.
