Treat a guinea pig's eye injury as urgent — see an exotic or small-animal vet the same day. Guinea pigs commonly scratch or poke an eye on hay, causing a painful corneal ulcer that can worsen within a day. A cloudy, weepy, closed, or bulging eye needs prompt care. Don't use leftover eye drops, prevent rubbing, and arrange a vet promptly.
## Why guinea pig eyes get hurt Guinea pigs feed with their faces buried in hay, so a stalk poking the eye is a frequent cause of injury. A scratch to the cornea is painful and prone to infection, and can deteriorate quickly. A white spot or haze on the eye often means an ulcer.
## Signs that need same-day care - Holding the eye closed or half-closed, or excessive blinking and watering. - Cloudiness, a white or blue haze, or a visible scratch. - Bulging of one eye, or a visible foreign body such as a hay strand. - Redness, swelling, or pawing at the eye.
## What not to do Don't use human or other-pet eye drops — some can harm the eye or hide a worsening ulcer. Keep the eye clean, stop your guinea pig rubbing it, and get a proper diagnosis, because ulcers, infections, and foreign bodies each need different treatment.
Get to a vet immediately if you see any of these
- A bulging eye or one eye clearly larger than the other
- Sudden cloudiness or a white/blue haze over the eye
- Eye held tightly shut with obvious pain
- A visible hay strand, foreign body, or scratch
- Not eating alongside the eye problem
Common questions
My guinea pig's eye is just watery — can it wait?
A watery eye should still be checked soon, as it can be an early ulcer or a poke from hay. If the eye is painful, cloudy, or closed, see a vet the same day.
How do guinea pigs get eye ulcers so often?
They eat with their faces in the hay, so a stalk easily scratches the cornea. A scratch can become a painful ulcer within a day, which is why prompt care matters.
Can I use my dog's eye drops?
No. Some preparations can harm the eye or mask a worsening ulcer. Only use what a vet prescribes for your guinea pig.
