What Do Guinea Pigs Eat In The Wild?

What Do Guinea Pigs Eat In The Wild_.

Wild guinea pigs are found in the grasslands and mountains of Brazil, Peru, Uruguay, and Argentina. They look almost the same as their domesticated counterparts. Wild guinea pigs are also commonly known as a Brazilian guinea pig. They have different scientific names Cavia aperea (wild guinea pigs) and Cavia porcellus (our domesticated pets).

This is where things get interesting because there are even more spices of wild guinea pigs, not only the Brazilian guinea pig. This is the full list of the wild guinea pigs:

Our domesticated guinea pigs are not included on this list as they do not exist in the wild anymore. Now, many people wonder what guinea pigs eat in the wild when they have no owner to look after them and that is exactly what you are going to find out in this article.

What do guinea pigs eat in the wild? Wild guinea pigs are also herbivores. They love eating flowers, grass, leaves, and almost everything that grows on the ground. Clover and dandelion leaves are a special treat for wild guinea pig’s taste and enjoyment. Some plants in the wild also aren’t good for wild guinea pig’s health but because of their good sense of smell they can sniff the plants and decide which is safe or poisonous for them. Guinea pigs in the wild are most active and awake in the dusk and dawn, which means they are also crepuscular animals just like our domesticated guinea pigs.

By knowing wild guinea pig’s habitat, behavior and diet, we can better understand domestic guinea pigs and their needs. We should provide them food that they’ve eaten in the wild because that will ensure better growth, lifespan, and health.

So, in this article we’ll talk about what do guinea pigs eat in the wild, their habitat, and differences between domestic and wild guinea pigs. Let’s start!

The Difference in Domestic and Wild Guinea Pigs

Guinea pigs in the wild are quite different from domestic guinea pigs in various contexts. The range of factors differs such as their emotions, exploration and anxiety, social attraction, stress levels, social behavior and psychological adaptations.

However, despite the differences in behavior, wild and domestic guinea pigs are herbivores, they require the same diet and look for the same kind of food.


Wild Guinea Pig Diet: Information

Wild Guinea Pig Diet

Guinea pigs are herbivores and they don’t eat meat. Wild guinea pigs don’t eat processed pellets unlike domestic guinea pigs to stay healthy. In the wild, they eat all types of grasses, wild vegetables and fruits, herbs, flowers, leaves but also in some cases stems, roots, seed, barks, and so on.

They don’t drink water if they eat foods with higher water content. Guinea pigs eat wild plants that they know are safe to eat, including chickweed and dandelion leaves. They adapt to their environment and they learn which foods they should avoid. Guinea pigs are also fond of eating fresh grass.

Being herbivorous animals, they eat plants and similar food items only to gain all the necessary nutrients needed for their survival. Wild guinea pig’s natural diet is full of vitamin C, which is of the extreme importance in order to live healthy and to survive effectively.


What Wild Plants Can Guinea Pigs Eat?

What Wild Plants Can Guinea Pigs Eat.

Most of the wild guinea pigs eat fresh grass and seasonal food for their diet from spring to fall. During the winter season, they tend to prefer wild vegetables. Guinea pigs find fresh herbs, leaves and even small branches that they use to wear down their teeth. The following are some of the most common foods or plants that guinea pigs eat in the wild.


Grass, Leaves and Flowers

The lush green grass is the favorite food of guinea pigs all over the world. A nice handful of lush green grass is a great snack for their appetite. While grazing in the wild, coming across poisonous plants is inevitable.

Eating a dangerous plant along with the thick grass could damage their health. They enjoy eating flowers, but buttercups and daisies are especially problematic. This is where their sense of smell works for them. They sniff the grass or flowers and eat which they deem safe.

Mown grass is considered dangerous for guinea pigs’ health as it contains fungus and disguised poisonous plants that have the potential to cause fatal conditions of bloating.

Wild guinea pigs also eat tree leaves as they are very nutritious for them, but there are also some leaves that can be poisonous to guinea pigs, such as ivy and oak tree leaves.


Fruits and Vegetables

Fresh fruits and vegetables are necessary for any guinea pig’s diet. They eat veggies and fruits in the wild to fulfill their nutritional intake of essential nutrients and vitamins. Guinea pigs drink water that is easily available to them in the wild. They also eat salad vegetables that contain water.

Guinea pigs like eating wild strawberries, wild blueberries, wild raspberries, dandelions, elderberry, wild black cherry, wild apples, wild asparagus, root vegetables, dark green leafy vegetables and many other vegetables and fruits that they can find in the wild.

Fruits are acidic in nature, and over-consumption can lead to the formation of sores around guinea pigs’ mouth.


Eating Patterns of Guinea Pigs in the Wild

Eating Patterns of Guinea Pigs in the Wild

Guinea pigs graze constantly instead of eating a large quantity of food at once. They normally do this in the twilight hours, when there is less chance of predators being around.

They tread firmed paths that are used to get between their burrows and food sources. In the wild, they can also be spotted in a mass gathering, when many guinea pigs are in the same area with abundant food.


Guinea Pig Diet Preference in the Wild

What do guinea pigs like to eat in the wild? Preferably, guinea pigs like to eat a vegan diet and eat almost everything that grows on the ground. Living amidst nature gives them access to a huge variety of plants that guinea pigs like to eat.

In the wild guinea pigs like to eat food that is rich with vitamin C and also food with enough amount of water. Especially, they love to eat wild clover, chickweed, and dandelion leaves.

Guinea pigs that live in the wild follow their instincts and eat what grows on the ground. But, because of predator risks, sometimes they need to eat some foods that we don’t give to domestic guinea pigs, like branches, seed, barks, and so on.


What Foods Guinea Pigs Avoid in the Wild?

A guinea pig’s digestive system is quite sensitive. They are fickle eaters of fruits and vegetables, but there are some fruits and vegetables that are NOT safe for guinea pigs.

These are the most popular questions when it comes to guinea pigs living in the wild: can guinea pigs eat wild garlic and are wild mushrooms poisonous to guinea pigs? Well, many people think that any plant which grows from a bulb, just like an onion, normally isn’t good for guinea pigs. This is certainly true as both wild and domestic guinea pigs can’t eat onions and garlic. Wild onion and wild garlic can cause some stomach problems for wild guinea pigs and this is why they will avoid it every time.

When it comes to wild mushrooms, guinea pigs also can’t eat wild mushrooms, because there are many wild mushrooms that are poisonous both for guinea pigs and for humans.

They don’t eat any kind of meat in the wild, and gassy foods and plants that contain oxalic acids in high amounts can be specifically problematic for guinea pigs.

Some plants that guinea pigs avoid in the wild are ivy and oak tree leaves, wild celery, wild rhubarb, buttercups, daisies and others.


Guinea Pig’s Wild Habitat

Guinea Pig Wild Habitat

Wild guinea pigs are found in large numbers in the grassy plains of Columbia, Brazil, Ecuador, Peru, and Bolivia. They enjoy digging themselves underground and co-exist in groups. Wild guinea pigs are very social and their small groups most often consist of one male, one or two females and their young, which are called pups.

Pups are usually born with open eyes and with hair. Right from the time of their birth, they are able to run and eat solid foods. Survival abilities of pups decrease the mortality rate among guinea pigs.

Wild guinea pigs need to be aware of predators as they like roaming and running in the open mountains and cherish their freedom. They use whistles to notify other group members about any danger in the same vicinity. Because of danger, guinea pigs are crepuscular animals that tend to be most active during dusk and dawn when it is harder for predators to find them.

Guinea pigs usually find hiding places or tunnels that are formed by vegetation and they move only in the small groups when searching for food and it is important to note that they don’t store their food.


Can Guinea Pigs Survive in the Wild?

Guinea pigs can survive in the wild because they live in herds and they have a well-developed survival instinct. They find shelters and are most active early in the morning and in the evening when there are not that many predators. Also, guinea pigs usually will go only a few meters away from their cover zone in order to search for food. Their covers are always in close proximity to the food source.

Guinea pigs can survive in the wild for up to 8 years, but because of the high risk of predators we can say that their average lifespan in the wild is only around 3 years, which is two times less when we compare them to our domestic guinea pigs.

What Do Guinea Pigs Eat In The Wild_1

Summary

Guinea pigs learn what to eat and what not to eat in the wild during their early life. These habits are difficult to change after maturity. They don’t respond well to a sudden change in their diet.

Sometimes wild guinea pigs will stop eating if they don’t find the food they are used to, this means that in some cases they will even choose to starve instead of trying something new in their diet.

Even if these guinea pigs live in the wild, they look almost the same as our cute pets. Hopefully things are now a little bit cleared when it comes to guinea pigs and their life in the wild.
