Can Guinea Pigs Eat Guava?

In this article, we will discuss the various aspects of feeding guavas to your guinea pig. We will also advise you on ways to feed guavas to your guinea pig.

Benefits of Guavas for Your Guinea Pig

Guavas are nutrient-rich fruits that are sure to provide vital nutrients for your guinea pig. Below, we will discuss the benefits of feeding guavas to your guinea pig.

Has Vitamin C

Vitamin C is a water-soluble vitamin that your cavy’s body cannot synthesize on its own. Vitamin C’s water-soluble property makes it hard to be retained in the body for a long time. Vitamin C is not stored in the body, so it quickly expels together with any excess water removed from the body. The results are that your guinea pig cannot retain vitamin C for long periods.

Guinea pigs need a steady supply of vitamin C for the absorption of a sufficient amount of it. Vitamin C significantly reduces the risk of your guinea pig developing heart diseases while boosting its immune system. Studies prove that vitamin C, as an antioxidant reservoir, can increase the antioxidant levels of your guinea pig by up to 30%.

Vitamin C deficiency in your guinea pig increases the chances of your cavy developing periodontal diseases such as scurvy, bleeding gums, and edema.

Contains Antioxidants

As your guinea pig’s body carries out complex functions such as digestion, it may expel free radicals. Free radicals cause oxidative stress that can eventually lead to arthritis, cancer, and heart diseases. Antioxidants come to the rescue by capturing and expelling these free radicals from your guinea pig’s body.

Lucky for your cavy, guavas contain antioxidants such as:

  • Protocatechuic acid
  • Quercetin
  • Ferulic acid
  • Ascorbic acid (Vitamin C)
  • Gallic acid
  • Caffeic acid

Has a High Fiber Content

Fiber comes in two forms, soluble fiber, and insoluble fiber. Insoluble fiber helps add bulk to food in your guinea pig’s stomach. This bulk ensures your guinea pig gets regular bowel movements preventing constipation.

On the other hand, soluble fiber helps regulate blood cholesterol levels. Cholesterol regulation helps prevent heart diseases arising from high cholesterol levels such as strokes and high blood pressure. Guavas contain a high amount of both types of fibers, thereby providing all these benefits.

Hydrates Your Guinea Pig

Guavas contain a very high water content, making about 80% (80.8 grams of water per 100 grams of guava) of the guava. Providing enough hydration prevents thirst in your guinea, especially during times of high temperatures and high activity.

Provides Energy

Carbohydrates are a group of foods known for their high energy output. An example of a vital carbohydrate is fructose sugar. Guavas possess a significant amount of carbohydrates (14.32 grams of carbohydrates per 100 grams of guava). These carbohydrates provide your cavy with enough energy to go through the day, foraging for food or playing.

Risks Associated With Feeding Guavas to Your Guinea Pig

Despite containing all these benefits, feeding your cavy too many guavas may cause some adverse effects for your pig. Some of the side effects are discussed below.

Developing Sugar Related Complications

Guavas are known to contain a high sugar content. However, guinea pigs do not have a sophisticated enough stomach to digest copious amounts of sugar. This problem might introduce your guinea pig to stomach aches, diarrhea, and vomiting.

A high sugar diet might cause diabetes, a debilitating disease that may prove fatal in the end. Your guinea pig’s teeth might also be at risk of developing cavities and other dental diseases.

Developing Urinary Complications

Guinea pigs can extract a large amount of calcium from guavas. However, an excessive intake of calcium might predispose your guinea pig to develop kidney and bladder stones. Bladder and kidney stones are accumulations of calcium and other minerals in the said organs.

These stones can cause scarring of the organ walls that may lead to blood in the urine. The arising blockage of kidney and bladder vessels prevents the expulsion of waste from your guinea pig’s bloodstream. Blocked waste might prove fatal as the toxic substances may cause damage to the body’s cells.

The leaves, seeds inside the flesh and skin of guava, are safe to eat, provided they are properly washed. It would be best if you fed guavas to your guinea pig at most twice per week. However, let us provide you with simple steps to follow when feeding guavas to your cavy:

  • Select organic and fresh guavas.
  • Wash the fruits thoroughly to rid any dirt and harmful chemicals on the surface.
