Guinea pigs may have red eyes due to a variety of reasons.
One possibility is that they are albino guinea pigs, which means they lack melanin pigmentation in their eyes.
Without melanin, the blood vessels in their eyes are more visible, giving them a red appearance. Another reason for red eyes in guinea pigs could be conjunctivitis, also known as pink eye.
This is an inflammation of the thin, clear tissue that covers the white part of the eye and the inner surface of the eyelids.
In some cases, conjunctivitis can cause the eyes to appear red and swollen. Additionally, if a guinea pig has a white fur coloration, the contrast between the white fur and the red eyes may be more noticeable.
It is important to monitor the red eyes in guinea pigs as they could be a sign of underlying health issues, such as infections or allergies.
If a guinea pig’s eyes appear consistently red or inflamed, it is recommended to consult a veterinarian for proper diagnosis and treatment.
