Guinea pigs are fantastic little fellows who fill our homes with so much joy and amusement. They may be small in size,  yet they possess big personalities. However, like humans, guinea pigs require the right foods that contain all the vital nutrients necessary for their development. Selecting the best guinea pig food is not a simple task so in this article, we will explore which products and brands are worth spending money on. Look out for our best choice, premium pick and best value products below. Let’s begin.

The Best Guinea Pig Food


The first guinea pig food on this list that is also the best choice for any guinea pig owner is the Oxbow Essentials Adult Guinea Pig (Timothy Based), which is prepared from the pasture grass known as timothy grass. A timothy grass based-pellet is better for adult guinea pigs than alfalfa-based hays. Your adult guinea pig’s organs need much lower levels of alfalfa-based grasses when compared to the requirements of younger guinea pigs. Oxbow Essentials guinea pig food is rich in fiber, which is vital for the growth and health of the adult guinea pig. This highly rated food is also vet-recommended as it contains vitamin C, which is essential for your guinea pig’s development. It doesn’t contain excessive amounts of calcium, and phosphorous as a high phosphorous diet will shorten the lifespan of your guinea pig. Oxbow Essentials pellets are lower in protein and calories and this balance is just right for your adult guinea pig’s digestive system.

Best Guinea Pig Food Buying Guide & FAQ

What to Look for in Guinea Pig Food

When purchasing guinea pig foods, you should look out for the following ingredients.

  • Vitamin C: Ensure that your guinea pig food contains enough vitamin C. Guinea pigs are mammals who are unable to produce vitamin C naturally on their own. Therefore it is essential to provide it to them directly through their feeding.
  • Hay: A good guinea pig food should have hay. Guinea pigs require hay for their dental health and digestive system.
  • Pellets: Your guinea pigs' pellet-based foods should also be high in energy. However, too much of it can result in your guinea pig becoming obese and also may lead to dental issues.
  • Natural vs Artificial: When buying guinea pig food, you should make sure that the food is fresh and natural. Avoid artificial foods as much as possible.

What to Avoid Feeding Your Guinea Pig

Avoid feeding your guinea pig the following:

  • Certain vegetables such as cabbage, potatoes, avocado, and lettuce.
  • Guinea pigs are herbivores and, as such, do not feed your Guinea pig with meat or dairy items.
  • Again, avoid feeding your guinea pigs with fruits that are high in sugar. Fruits with sugar must be served in moderation.
  • Avoid foods that are highly rich in calcium and protein.
  • Do not offer your guinea pig citrus fruits such as orange, lime, and lemon.

Types of Guinea Pig Food

There are different types of guinea pig food on the market. However, depending on the ingredients and composition, guinea pig foods can be classified into three different types – pellets, hays, and treats.

  • Guinea Pig Pellets: They contain vitamins A to E and minerals like phosphorous and biotin. Do not feed them with pellets that are made up of nuts or preservatives.
  • Guinea Pig Hay: There are different types of Guinea pig hays, but the famous ones are grass hays and Timothy hays. Hays imitate the forest like or natural surroundings of guinea pigs in the bush. As such, Guinea Pigs are traditionally attracted to its natural texture and scent.
  • Guinea Pig Treats:  Your pig will enjoy treats that are high in nutrients and minerals. Treats that contain a lot of sugar should be avoided.
  • Complete Guinea Pig Diets: A perfect Guinea pig diet should consist of a well-balanced protein, calcium, phosphorus, and vitamins that are important for your guinea pig’s growth. It should also be made up of the right number of pellets, hays, and treats.

A: You should feed your Guinea pig once every day with about 1/6 cup (medium size) of pellets and supplement it with a small number of vegetables and an unlimited amount of hays.

Q: Can guinea pigs just eat pellets?

A: You should serve them with varieties such as vegetables, freshwater, and hays. Pellets are useful for your guinea pigs, but they are supplements and should not be viewed as the major meal of the day.

Q: Can guinea pigs eat dog food or cat food?

A: Most pet foods are made for a specific target audience and are not generic. Thus, before the staples are made, they take into consideration the nutritional requirements of each pet. So, a cat or dog food may not contain the dietary components or ingredients that your guinea pig needs for his growth and general wellbeing.
