Best Guinea Pig Food Buying Guide & FAQ

What to Look for in Guinea Pig Food

When purchasing food for guinea pigs, look out for the following ingredients.

  • Vitamin C: Ensure that your guinea pig food contains enough vitamin C, either added or natural. Guinea pigs are mammals who are unable to produce vitamin C naturally on their own, so it’s essential to provide it to them directly through their diet.
  • Quality Hay: A good guinea pig food should have plenty of grass hay or Timothy hay. Guinea pigs require hay for their dental health and digestive system, so this should comprise the majority of their diet (75% to be precise).
  • 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, so it’s best to search for a balanced recipe. Treats can be an exception, of course.
  • Natural vs Artificial: When buying food for your piggie, make sure that the food is fresh and natural. It’s best to go for brands that use high-quality ingredients that are grown in the USA. Avoid artificial additives because some guinea pigs can have sensitive digestive systems. This being said, for most piggies, added flavors are fine in small amounts, i.e. treats.
  • Fruits and Veggies: your piggie should also have access to fresh veggies and some fruits, including spinach, kale, romaine lettuce, cucumber, carrots, zucchini and sweet potatoes. As for fruits, you can give them occasionally to your pet as they can be high in sugar. Oranges (which are high in vitamin C!), apples, papaya, pears and other are good choices. Of course, you can also look for these ingredients in commercially prepared foods, but serving them fresh is always the best!

What to Avoid Feeding Your Guinea Pig

Avoid giving your piggie the following foods and ingredients:

  • Certain vegetables such as cabbage, potatoes, avocado, and lettuce.
  • Guinea pigs are herbivores and, as such, should not eat meat or dairy items.
  • Again, avoid feeding your guinea pigs with fruits that are high in sugar. While ok occasionally as treats, fruits high in sugar are not recommended on a daily basis.
  • Avoid foods that are highly rich in calcium and protein.
  • Also avoid the obvious offenders such as candy, chocolate, onions, garlic and caffeine.

Types of Guinea Pig Food

There are various types of food for guine pigs on the market. However, depending on the ingredients and composition, they can be classified into three different types – pellets, hays, and treats.

  • Hay: There are different types of hays available, but the best ones are grass hays and Timothy hay. Hay imitates the forest like or natural surroundings of guinea pigs in the bush, so they are naturally attracted to its texture and scent. Hay is also an excellent source of fiber and should comprise 75% of your pet’s diet.
  • Pellets: They contain vitamins A to E and minerals like phosphorous and biotin and are a good supplementation to your piggie’s hay diet. Do not feed your piggie with pellets that are made up of nuts or preservatives though.
  •  Treats:  Your pig will enjoy treats that delicious and are high in nutrients and minerals. However, treats that contain a lot of sugar should be avoided.
  • Complete diets: A perfect piggie diet should consist of nicely balanced macro and micronutrients, meaning protein, fiber, calcium, phosphorus, and vitamins that are important for your guinea pig’s growth. While some commercial foods boast the “complete” label on their packaging, your piggie’s diet should mainly consist of hay, while the rest of foods can be considered supplements.

Best Guinea Pig Food Brands 

Some of the best brands that can currently be found on the market include:

  • Oxbow Guinea Pig Cuisine: This brand of food is made explicitly for older guinea pigs. It consists of fiber and vitamin C, both of which are vital for guinea pigs. It also has no additives and preservatives.
  • Sweet Meadow Timothy Guinea Pig Pellets: This product is manufactured for guinea pigs age nine months and above. It is also rich in vitamin C and calcium.
  • Burgess Excel Guinea Pig Food: Burgess Excel has 36 percent of fiber and is an excellent source of vitamin C.
  • Supreme Selective Fortified Diet for Guinea Pigs: This tasty variety has no sugar content, as such, it helps to prevent obesity.
  • Small Pet Select Guinea Pig Food Pellets: This brand’s ingredients are fully sourced in the United States, so they’re of good quality. The recipe also consists of healthful vitamins and high-grade Timothy hays.

Best Guinea Pig Food FAQ:

Q: How much should I feed my guinea pig?

A: You should feed your pet once every day with about 1/6 cup – 1/8 cup (medium size) of pellets and supplement it with a small number of vegetables and an unlimited amount of hays. Occasionally, low-sugar fruits are also welcome.

Q: Can guinea pigs just eat pellets?

A: You should serve your guinea pigs with a variety of foods such as fresh hay, vegetables, sometimes seeds and fruits. 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, manufacturers take into consideration the nutritional requirements of each pet. For this reason, it’s not recommended you feed your piggies dog or cat food – they simply don’t contain all the nutrients your pets need to thrive.
