Benefits of Scallions to Guinea Pigs

A healthy and happy pet will generate the same energy for you and keep you smiling. Now that we’ve known your guinea pigs can feed on the leafy section of scallions, let’s find out what other benefits they provide your animal.

Energy Boost

Scallions provide your guinea pig with both proteins and carbohydrates. Carbs provide a quick burst of energy, while proteins give a constant stream of energy over time. Your guinea pig will have enough energy from feeding on scallions.

Nutritional Fats

Scallions have a modest amount of fat in them. These fats dissolve in their blood and:

  • Improves their brain’s function
  • Improves their brain performance
  • Aid in the absorption of other nutrients

With zero cholesterol in these onions, your guinea pigs have a lower chance of developing clogged blood vessels. This reduces the risk of your guinea contracting cardiovascular disorders.


Vitamins are vital nutrients for your guinea pig. Enough amounts of vitamins boost the health of your pet. Scallions contain healthy nutrients, which include:

Vitamin C

These green onions contain a massive amount of vitamin C. Vitamin C protects guinea pigs from serious diseases such as scurvy resulting from a vitamin C deficiency.

Vitamin C deficiency causes your guinea to develop a rough coat. This may go ahead to include external bleeding wounds that may not heal properly.

Vitamin B

Scallions have two types of vitamin B which are:

  • Vitamin B6: Vitamin B6 stimulates the production of serotonin hormone in your guinea pig. This hormone is responsible for reducing anxiety and depression in your pet.
  • Folate vitamins: Folate is essential for the proper development of a fetus for a lower risk of birth abnormalities.

Other nutrients in scallions are Manganese and Selenium, which help in boosting the immune system. Zinc and iron help in DNA metabolism and blood cell production, respectively.

Health Risks of Scallions to Guinea Pigs

Scallions appear to be pretty beneficial to guinea pigs. They can, however, be deadly if they’re consumed in large quantities, just like any other food.

It would be best to avoid overfeeding your guinea pigs with scallions. Some potential dangers of overfeeding scallions to your guinea pigs include:

Bladder or Kidney Stones Formation

The calcium in scallions is essential for the growth and development of strong bones. However, if your guinea pigs ingest too much of it, it may build up and lead to bladder or kidney stones.

Kidney stones can have your guinea pig experiencing:

  • Bloody urine
  • Painful urination
  • Renal failure

So, give your guinea pigs scallions in moderate proportions to have them receive just enough calcium.

Digestive Problems

Excessive bowel movements and loose motions are caused by too much fiber from scallions. A diet consisting of too much fiber may lead to an electrolyte imbalance in your guinea pig.

This imbalance may bring about stomach upset, vomiting, flatulence, and even diarrhea in severe cases.

Preparation of Scallions for Your Guinea Pig

First, you’ll have to wash the scallions to ensure the dirt is off. You’ll notice they have three sections; a green leafy top, a white part, and the bulb at the very end.

Cut the scallions right below the green leafy part, advisably having less of the white part. The white part is considered more ‘oniony’ and is used when cooking. The leafy part you’ve obtained is safe for guinea pigs to eat.
