If you’re a new guinea pig owner, there is a high chance of you buying the wrong product, and it could cause health issues for your guinea pig. We care about your pet’s health, which is why we have made a detailed buying guide that will help you select the best guinea pig food.

This type of guinea pig food has of equal pieces that all contain the same amount of nutrients and ingredients. It is vital because your guinea pig should get the same amount of balanced nutrients whether he eats the entire bowl of food or eats half. These pellets are usually made from a mixture of grains, hay, and legumes; they are also fortified with minerals and vitamins that your guinea pig needs, such as vitamins A to E, biotin, and phosphorous. However, do not feed your guinea pig with pellets made from nuts or preservatives, and ensure that you feed your guinea pig with a range of fresh fruits and vegetables.


This type of guinea pig food has of a mixture of pellets, dried legumes, corn flakes, pieces of dried vegetables and fruits, and other similar ingredients. These types of food may look interesting, but they aren’t the best choice for your guinea pig. Most guinea pigs tend to eat their favorite parts and leave the rest, and their favourite part tends to be bits with fruits, vegetables, and flaked grains, so they leave the pellets that have been fortified with nutrients, so most cavies end up not getting all the vital nutrients.


There are different types of hay available on the market, but the best option is grass hays such as Timothy hay, meadow hay, or orchard hay. Hay imitates the natural surroundings of guinea pigs in the wild, so they are attracted to its scent and appearance. Hay is an excellent source of fiber and should make up 75% of your guinea pig’s diet. However, alfalfa hay and legume hay shouldn’t be given to your guinea pig on a daily basis as they are too high in protein and calcium. Hay aids the digestion of your guinea pig, so make sure you get hay from a reputable supplier and opt for second or third cut hay as first cut hay has too many stems and seeds, making it tough for guinea pigs to chew digest. Ensure you feed your guinea pig hay through a feeder instead of placing it on the cage’s floor to avoid soiling.


Guinea pigs enjoy treats that are delicious and rich in nutrients and minerals but make sure to avoid treats that contain a lot of sugar.

Complete Diets

A perfect guinea pig should contain nicely balanced macro and micronutrients, including protein, calcium, fiber, vitamins, and phosphorus, as they are important to the growth of your guinea pig. Most commercial guinea pig foods claim they contain the complete ingredients, but your cavies food should mainly have hay while the other foods can be counted as supplements.


When buying food for your guinea pig, make sure you keep an eye out for the following factors.


The ingredients of your guinea pig’s food play a vital role in your pet’s health. Most guinea pig food contains fruits, vegetables, grains, timothy hay, and other similar contents that provide them with the essential nutrients they need; however, it is important that the food doesn’t contain any artificial sugar, added preservatives, or harmful chemicals as they could lead to cancer and other diseases. Also, if your guinea pig is allergic to a specific food such as peanuts, make sure that the food you choose doesn’t contain the allergen.


It is important that your guinea pig’s food contains all the right balance of nutrients to keep your cavies healthy. Ensure you check the guaranteed analysis. A good quality guinea pig food contains between 12% and 16% fiber, 2% to 5% fat, 18% to 20% protein. It is also vital that you pay attention to the vitamin C content of the food. Guinea pigs can’t produce vitamin C on their own, so they have to eat between 30 to 50 milligrams daily. Most times, it’s best for them to get most of their vitamin C from pellet food, but some of it could also come from fresh food. You could feed your guinea pig foods rich in vitamin C, such as bell peppers, squash, asparagus, zucchini, kale, broccoli, cabbage, and other cruciferous vegetables. These vegetables contain significant amounts of vitamin C, but they should be given to your cavies only once weekly. Your guinea pigs’ food should also contain a healthy balance of vitamin A, omega 3, and other essential minerals as they help improve their immune system and their fur.


Your guinea pig’s food might get wasted if the taste doesn’t match your pet’s taste buds. Cavies foods come in different flavours in the market; some come in timothy hay flavor while others have a mixed fruit and vegetable flavor. So, before purchasing guinea pig food, make sure that the flavour matches the preferred taste of your pet.


When purchasing guinea pig food, it is best to note the size package to buy. Guinea pig food comes in different sizes. Try a small package first to see if it meets their needs; once they are used to the food, you can get a larger size.

Most cavies owners buy small to medium-sized packs containing about 1 to 5 pounds of food, which is great if you’re feeding a pair or small group of guinea pigs. However, you can buy a large bag of 25 pounds or more if you have a large number of guinea pigs to feed as it is cheaper in the long run.

Uniform Pellets

It is important for you to note the chunk size and shape when getting guinea pig food. Some formulas come with various shape and size, which leads to varied portions. It could also lead to choking for your pet, which is why it is vital to opt for a guinea pig food that has uniform pellets that come in small to medium chunks so that aids you in providing your pet with a good quantity of food daily.

Natural Vs. Artificial

When choosing food for your guinea pig, make sure you opt for one that contains only fresh and natural ingredients. It is best to opt for brands that use high-quality ingredients and avoid artificial additives because some guinea pigs have sensitive stomachs. On the other hand, it is okay to give most guinea pigs added flavors in small amounts as treats.

Age Suitability

Some guinea pig foods are specially formulated for adult life stages of the cavies. However, some other foods can be given to your cavies at all stages of life. That is why it is important to check the details of age suitability before purchasing your guinea pig’s food.

If you would prefer buying your guinea pig’s food in bulk, you’ll be spending between $20 to $50.

Guinea pigs require diets rich in vitamin C because they can’t create it on their own. A lack of vitamin C in their diet leads to scurvy, which is a painful disease that leads to suffering. In order to prevent scurvy, you need to feed your guinea pig with fresh fruits cut into small pieces.

However, fruits have a high sugar level, so it’s best to serve them only bite-sized portions of fruits. Your guinea pig should be able to get sufficient amounts of vitamin C from pellet food containing vitamin C supplements and vegetables. No matter the age of your guinea pig, you can give them small pieces of pears, blueberries, apples, kiwi, strawberries, papayas, peaches, and tomatoes. However, do not give your guinea pig cold fruits.


Even though your guinea pig’s diet should be high in vitamin C, they also need fiber which comes in timothy grass hay and other grass hay, to promote digestion and proper dental health. They should always have a fresh supply of hay and clean water.

You can feed your guinea pig with fresh vegetables once a day. The total amount of vegetables your pet should eat per day shouldn’t be more than a cup.

  • Ensure that your pet has good access to clean water. You can provide them with clean water using a bowl or a small animal water bottle if they keep knocking the water bowl over or contaminate it with poo or other contaminants.
  • If you need to change your guinea pig’s diet, make sure that you make the switch gradually. Making the change slowly will allow you to avoid upset stomachs and make them accustomed to the new meal over a week. Slowly reduce the amount of old food they get each day and replace it with a higher amount of the new food.


When you’re trying to change your guinea pig’s food, make sure that you start with a mixture of the old food and new food so that he can slowly adjust to the change. Over the course of 7 to 10 days, you can gradually increase the amount of new food. Some people recommend that the process should take two weeks and that isn’t a bad idea.

Guinea pigs are small, fragile animals that have bodies that react to sudden changes in their diet. Even if you’re changing their food to a higher quality option, it could still upset their stomach.
