Eye discharge also helps guinea pigs clean their faces. If you notice the discharge to be a white or creamy texture, it’s absolutely fine. Pretend it’s an automatic soap dispenser they have built into their eyes to use for quick cleanings.

This is a self-grooming animal that uses the discharge for grooming and regular hygienic practices. We love seeing our cute cavies rubbing their faces with the discharge a few times a day as an act of face washing. It’s adorable for us to watch and useful for them to do so.
