Guinea pigs have an Oculomotor System that allows them to control their eye movement completely. But why guinea pigs do so?

Guinea pigs are prey animals, and they want their predators to see them awake all the time. So they always need to be on guard to get caught.

However, the little guinea pigs close their eyes when they mate with their partner and feel comfortable. This means when guinea pigs are satisfied, they close their eyes.

How do Guinea Pigs Eyelids work?

In the mammal world, guinea pigs have also developed advanced oculomotor systems. This system helps them regulate their eye movement, how they blink, and whether or not they can take over the manual control.

Moreover, when guinea pigs feel imminent fear, their system allows them to suppress the blinking of eyes for hours and hours.

However, guinea pigs as pets or domesticated ones blink their eyes more often than wild guinea pigs.
