Recently, a foster carer noticed something worrying with one of her baby guinea pigs. The little runt had been squinting with one eye, and a few days later the eye looked cloudy and sore. She was told it was “normal” – but her instincts said otherwise.
And she was right to question it. Eye problems in guinea pigs and rabbits are never normal. They can range from minor scratches to serious ulcers, and because small animals hide pain so well, it’s important for us as carers to act quickly.
At Guinea Gourmet Treats, we see first-hand how many rescues deal with eye injuries and infections. Understanding what’s “just a hay poke” versus something more serious can help you know when to seek veterinary help.
Common Eye Problems in Guinea Pigs and Rabbits
Here are some of the most common issues seen in guinea pigs and rabbits:
Hay Poke
Sharp hay strands can easily poke the eye, leading to watering, blinking, or squinting. Sometimes these resolve on their own, but they can also cause scratches that develop into ulcers.
Corneal Ulcers
These are painful sores on the surface of the eye, often caused by hay pokes or scratches. They need vet treatment (usually a dye test to confirm and medicated drops). Left untreated, ulcers can lead to loss of the eye.
Conjunctivitis (“Pink Eye”)
Caused by irritation, dust, or bacterial infection. Signs include redness, swelling, and discharge. Guinea pigs and rabbits with conjunctivitis should be seen by a vet to rule out underlying issues.
Infections or Abscesses
Eye infections may stem from dental problems, as overgrown roots can press on tear ducts. Abscesses around the eye are also common in rabbits. Both need veterinary investigation.
Cataracts
These appear as a white or cloudy film across the lens. Cataracts usually develop with age or due to genetics. They don’t cause pain but can affect vision.
Entropion
This is where the eyelid folds inward, rubbing against the eye. It’s more common in rabbits and may need surgical correction.
Symptoms You Should Never Ignore
If you notice any of the following, it’s time for a vet check:
- Squinting or holding one eye closed
- Cloudy, white, or bluish film over the eye
- Redness, swelling, or discharge
- Excessive blinking or watering
- Crusting around the eye
- Sudden changes in eye shape or size
Why Quick Action Matters
Unlike humans, guinea pigs and rabbits can’t tell us when they’re in pain. Eye problems progress fast – a simple hay poke can turn into an ulcer within days. Early treatment often means the difference between a full recovery and long-term damage.

Supporting Your Pets’ Eye Health at Home
While eye problems usually need veterinary care, there are things you can do to help reduce risks:
- Use soft, dust-extracted hay to reduce pokes and irritation.
- Keep enclosures clean and free from sharp objects.
- Provide a balanced diet high in vitamin C for guinea pigs (prevents immune weakness).
- Check eyes daily during feeding time for early signs of problems.

Final Thoughts
If you ever notice your guinea pig or rabbit squinting, with cloudy eyes, or showing sudden changes – don’t wait it out. Trust your gut, just like the foster carer did. These small signs can point to something serious, and early veterinary care makes all the difference.
