Many guinea pig owners are surprised when they discover that their guinea pigs almost always have their eyes open, even when they sleep. This is why many people think that guinea pigs are nocturnal animals, which isn’t the truth.
So, can guinea pigs close their eyes? Guinea pigs can close their eyes but they don’t do it very often. Unlike humans, guinea pigs will keep their eyes open for the majority of the time, even when they are sleeping. They will close their eyes only if they feel comfortable and safe in their surroundings.
Guinea pigs use their eyes very differently from humans. If you notice that your guinea pig always seems awake and alert, do not worry. This is entirely normal. Although you may not see it very often, guinea pigs can close their eyes and blink.
In the following section, you can read more about guinea pigs’ eyes, find out why our guinea pigs don’t close them and why do they sleep with their eyes open. Let’s begin!
Why Doesn’t My Guinea Pig Close Its Eyes?
After you adopt your guinea pig, the first thing that you will notice is that they almost never close their eyes. You might even begin to worry that there is something wrong with your pet.
Guinea pigs are prey animals who are used to danger and attacks from larger predators. They will keep their eyes open to stay alert. In case any form of threat arises, this behavior allows them to quickly run to safety. Even though your guinea pig is domesticated and living the good life in a comfortable cage, this behavior is an instinct to them.
Guinea pigs even sleep with their eyes open. Your pet will only sleep with its eyes closed when it feels completely safe. This is a behavior you will rarely see since guinea pigs hide in order to feel secure. If you catch your guinea pig laying down with its eyes mostly open and it doesn’t seem alert or engaged with you or its cage mates, do your best not to disturb your pet as it might be sleeping. Guinea pigs love their sleep just as much as humans.
Do Guinea Pigs Have Good Vision?
The reason why guinea pigs keep their eyes open has nothing to do with their vision. Guinea pigs have big eyes that are very expressive. They are naturally near-sighted and they can see different colors. Their eyes slightly stick out from their face on the sides, which gives them a special perspective of their surroundings. Guinea pigs can see down the whole length of their tiny bodies. This allows them to be more aware of their environment.
Guinea pigs will keep their eyes open to protect themselves from any possible threat but they are also naturally curious and social animals. Most of the time, when they are safe in their cage, they are just observing you and the activity outside of their cage.
If you and your guinea pig have a close relationship, they can sense when you are near, even if they can’t see you. Your pet may also meet you at the door of the cage, especially when its meal or treat time.
How Do Guinea Pigs Sleep With Their Eyes Open?
Since you will very rarely catch your guinea pig with its eyes closed, you may think that they don’t sleep that much. Honestly, your guinea pig probably sleeps more than you. Before guinea pigs were domesticated, they lived in the wild on one of the lowest levels of the food chain. They were prey to other wild animals.
Although they move fast to greet you, guinea pigs could rarely outrun a larger predator in nature. Over time, natural selection ensured the survival of guinea pigs by creating a new breed that could sleep with their eyes open.
Today, even though guinea pigs are domesticated, they still sleep with their eyes open. If you ever noticed your guinea pig laying around their cage with their eyes open, or partially open, they are probably taking a nap or resting. As you bond with your pet, you will learn the difference between your guinea pig’s behavior when they are sleeping and when they are awake.
