However, because green onions are classified as a bulb vegetable, the cavies can only consume the top green leafy sections. The onion bulb is unsuitable for guinea pigs and may include either moderately poisonous or overly strong nutrients.

Thus, ‘Eating Onions’ is not always the greatest choice for your guinea pigs (your guinea pig can safely ingest only the top part, in moderation). 

That being stated, listed below are some of the health benefits of this vegetable:

  • To begin with, Green Onions are high in nutrients such as carbs and proteins. These nutrients are a fantastic source of energy since they provide both a sudden burst of energy as well as a constant supply. These veggies are also high in fiber. The fibers help in smooth digestion. Furthermore, the fibers also regulate bowel movements and aid in colon emptying.
  • Scallions, often known as green onions, contain trace levels of fat. Fat is a nutrient required for the proper functioning of the brain and energy. Additionally, all blood vessels remain healthy and unclogged with no cholesterol, and cardiovascular health is excellent.
  • There are additional vitamins for less inflammation and overall organ function, such as vitamin E for cancer prevention, healthy skin, and eyesight. The most vital vitamin for guinea pigs is vitamin C, which is found in green onions! This vitamin protects cavies against disorders such as scurvy (this damages their fur, makes them bleed, causes loose stool, no appetite).
  • Green Onions are also safe for pregnant guinea pigs to eat. This is due to the fact that they contain vitamin B.
