The Most Healthy and Favorite Foods of the Guinea Pigs

The Most Healthy and Favorite Foods of the Guinea Pigs

Guinea pigs thrive off fresh produce and pellets. They love consuming branches, herbs, and basically most kinds of plants and produce. You can think of guinea pigs as animals that love things that grow on the ground, and they like them raw.

Also, before feeding them, measure servings carefully. Too much of anything healthy can even be harmful to the guinea pig.

As a rule of thumb, your little furry pet must have hay and grass at all times. If you can, find and purchase timothy grass because its leaves grow like a roll-shape and not a regular fold. This grass makes guinea pigs digest foods better. It gives them needed fiber and also helps with their teeth overgrowth.

The other most popular one is alfalfa hay, which guinea pigs love. It is most suitable for younger guinea pigs. It is a legume and it has small flowers and leaves.

Do not serve too much of this to your guinea pig because it has a high amount of calcium and calories. Too much alfalfa hay can create stones in their urinary tract.

The other favorite food is the bell pepper. The guinea pig binges on these peppers because they have vitamin C. Both green and red ones are great. If your guinea pig lacks vitamin C a lot, opt for red bell peppers since they have a double dose of the vitamin.

Another favorite food is pellets. They must be plain and the servings are 2 oz. every day.

Carrots are another great and healthy treat. The guinea pig can eat one carrot daily. That way, it gets beta-carotene which the guinea pig needs.

The most favorite fruit of the guinea pig is the apple. You can feed it a few small pieces daily, but ensure to remove the seeds inside. Also, once in a while, you can treat the guinea pig with oranges and strawberries. Avoid dried fruits because they have lots of sugar added.

Other foods guinea pigs love are:

  • Blueberries
  • Melon
  • Papaya
  • Peach
  • Pear
