What Do Guinea Pigs Eat In The Wild?

In order to make the best decision for what food your guinea pig should be eating while in your care, it's important to first learn what guinea pigs eat in the wild.

While your guinea pig may live indoors with a plush lifestyle, their biological needs must still be met. Guinea pigs have been eating the same things for thousands of years, so their bodies are fine-tuned for that diet and require nutrients similar to that natural diet.

Guinea pigs are herbivores, meaning that they only eat plant matter. This makes their diet a lot more simple than if they were omnivores. Of the various types of plant matter that they eat, grass is one of the most frequently eaten. Hay is also eaten when found, as it's essentially just dry grass.

In addition to grass, vegetables are also eaten. Although they're found less commonly than grass, they are delicious additions to their diet and provide them with essential vitamins and minerals. One of these vitamins that is necessary is vitamin c, and this topic will be discussed in a bit.

Guinea Pigs Eating Poop And Grass

Guinea pigs eat two things very frequently, which are grass and poop. This diet sounds repulsive, but it's actually essential for maintaining their good health and getting the most out of their food.

As stated, grass and hay are going to make up the biggest part of a guinea pig's diet. This may seem like an unfulfilling diet, but it provides excellent nutritional value for them. One of the main perks of grass is that it provides vitamin C - a vitamin that isn't produced by guinea pigs naturally. A lack of vitamin C can result in serious medical problems like scurvy, so it's essential that a guinea pig is able to get this vitamin.

In addition to grass, guinea pigs eat their poop... Which is essentially just eating the grass again. Basically, plant matter is very difficult to digest. When the plant matter first gets exposed to the bacteria in the digestive system, it's broken down and digested, but only partially. So, animals that primarily eat plant matter have special ways to get the most nutrients out of their food.

Cows regurgitate their food from their stomach, chew it again (that's their "cud"), and digest it once again. Guinea pigs do the same thing, except their food entirely passes through the digestive system before being chewed again.

So, while it is gross to see, let your piggie eat their poop! It's how they get their essential nutrients and keeps them nice and healthy.

How To Properly Feed Your Guinea Pig

There are a few things that you'll want to consider while feeding your guinea pigs to make sure that their diets are complete. To begin with, I'll build on what I was talking about earlier -- hay and it's importance for guinea pigs. You'll want to supply your piggie with a constant supply of hay to constantly be chewing on, and supplement the rest of their diet with vegetables, a small amount of fruit, and some of the food from our list.

What about portion sizes? How much should your guinea pig be eating? Well... specific guidelines are few and far between. There isn't a specific number, meaning that it helps to know your individual guinea pig. In general, guinea pigs don't need a lot of energy as they're fairly inactive creatures.

Therefore, guinea pigs can be subject to obesity if they're overfed. This means that you should keep an eye on your guinea pig, and if you ever see them gaining weight, cut back on their portion sizes.

When introducing your guinea pig to new food, it's important to make the process slow and gradual to avoid distress. The first time that you feed your guinea pig a new food, mix it into their old food with the new making up only about 10% of the total food. Over the next week or two, slowly increase the percentage of new food as you see fit. Dietary changes that are too fast can cause looser bowel movements due to guinea pigs' sensitive digestive systems.

Supplementing your guinea pig's diet is important, too. On top of the hay, grass, and guinea pig pellets, it's a good idea to supplement their diet with a few healthy greens. Fruits are very high in sugar, so a very small portion should be used as an occasional treat. Vegetables are much better, and it's well worth it to incorporate raw veggies such as broccoli, cabbage, and celery.

Above all this, though, make sure that your guinea pig has constant access to fresh hay and fresh water.

What Defines The Best Guinea Pig Food?

Hopefully it's been made clear that guinea pigs need a specific diet in order for them to be happy and healthy. The best guinea pig food meets a guinea pig's specific dietary requirements and helps to round out their nutrition. Below are some of the main characteristics of healthy guinea pig food:

  • Nutrition - The nutritional content of a guinea pig food is the most important aspect to consider. Young guinea pigs require higher protein and more nutrients in general than an adult rabbit, but adult guinea pigs need about 18-20% protein, around 14-16% fiber, and very low fat, preferably 5% or under. Look for pellets that are packed with natural ingredients and have a huge focus on grass and hay to keep it in line with their natural diet.
  • Brand - While brand may seem unimportant, when it comes to guinea pig food, it's something that could be considered. Cheaper food made by an unknown brand is usually cheaper due to its lack of quality ingredients and presence of fillers that fill your piggie but cause malnutrition. Reputable brands have more to lose if their food has bad results, so it's almost always a better investment to get your guinea pig food from established brands.
  • Flavor - Guinea pigs have taste buds and are able to determine if they like a food or not based off of taste. Therefore, you would want to read reviews from owners on how their guinea pigs responded to the food. Additionally, start with small quantities of the food to make sure that your guinea pig likes it.
  • Form - The form of a guinea pig's food is very important for their health. Guinea pigs need hard food to keep their constantly growing teeth the right length and their jaws healthy. Food that's too soft won't work these areas as needed, and guinea pigs will need supplemental things to chew.
  • Life stage - The age of your guinea pig is also something else that influences what they should eat. Growing guinea pigs require more protein and more food in general since they're still growing. Adult guinea pigs spend a lot less energy to live, so they require less protein in their food.

What Is The Best Guinea Pig Food?

We've taken a look at many different guinea pig foods, taking into account things such as the quality of ingredients, the price per pound, and the physical health and enthusiasm of the guinea pigs that eat each food. Through this, we've found the 5 best guinea pig foods for you to feed your piggie.

Remember, every guinea pig is different. So while there is a very good chance that your rabbit would respond well to the foods listed below, they may also react negatively to it.

Supreme Petfoods

Supreme Selective Fortified Diet



Our Rating

Supreme Petfoods is a popular brand in the small pet food space, and this Supreme Selective Fortified Diet is a great creation by them. This food contains a lot of natural ingredients such as dandelion and fennel that's high in fiber and promotes healthy teeth and digestion. Additionally, it has added components such as vitamin C to meet your guinea pig's standards and linseed for a healthy coat and skin. There are no added sugars to this food, but it's still a tasty meal for piggies to help them get their essential vitamins and nutrients.

Owners are overwhelmingly happy with this food and tend to use it for years upon years. Many guinea pigs seem to only want to eat this food and reject others until they get it, which proves that it's pretty tasty. Additionally, it's resulted in beautiful coats and lots of energy for the guinea pigs that eat it.

Basically the only downside to this food lies in the fact that it uses alfalfa meal as the first ingredient. Alfalfa is generally not fed to adult guinea pigs due to the higher calcium content that can cause kidney stones. Therefore, you'll want to limit your guinea pig's consumption of this food to keep them away from this problem.


  • Limited ingredient list that's very natural
  • Tasty for guinea pigs
  • Good vitamin C and omega 3 content


  • Contains alfalfa which is too high in calcium

Supreme Petfoods

Tiny Friends Farm Gerty Food



Our Rating

While we generally try to add some diversity to our top product lists, Supreme Petfoods is just too good at making quality guinea pig food. This Tiny Friends Farm Gerty Food is a great alternative to the previous food by Supreme Petfoods, with the main difference being that this food is a mixed food. That means that it's made up of a variety of natural ingredients that encourages natural foraging. The variety of ingredients also ensures that it's a nutritionally-complete diet to give your guinea pig the nutrients that it needs. The vitamin C content of this food is excellent, and the taste is up there as well.

Guinea pig owners love this food, to put it simply. The tasty mix of ingredients is a hit among guinea pigs and doesn't promote selective feeding - a problem that exists with other mixed foods. Owners love that it has enough vitamin C to where they don't have to supplement it, and the texture promotes healthy teeth.

The big downside to this food is that it's generally more expensive per pound than other foods. This can be a problem for some households where money is tight. Additionally, alfalfa is one of the top ingredients, and this can make the food too calcium heavy. Fortunately, there is a wide variety of ingredients which means the calcium concentration probably isn't too high.


  • Very tasty mix
  • Lots of high quality ingredients
  • Nutritionally-complete


  • Generally more pricey
  • Contains alfalfa
