It is the most widely cultivated species of the genus Allium, as well as the bulb onion or common onion. Shallots, which were previously classed as a separate species, are a variety of the onion. Garlic, leek, chive, and scallion are close relatives.

Onions are considered vegetables. The edible parts of an onion are called vegetables. You can categorize vegetables according to their edible parts, such as roots, flowers, tubers, leaves, stems, and bulbs.

Due to two main ingredients, onions are harmful to guinea pigs. They are composed of compounds called thiosulphates and disulfides. Guinea pigs and many other animals people keep as pets are highly sensitive to both of these compounds.

Hydrogen, oxygen, and sulfur are present in thiosulfate. Compounds containing disulfide bonds are often found in proteins of the foo family. Guinea pigs, dogs, and other animals are incredibly toxic to both of these ingredients.

There are a number of other poisonous compounds in onions that guinea pigs can die from. Sugar and calcium are consumed at a much higher rate than guinea pigs should consume, leading to sugar and calcium overload.

Scallions have a small amount of fat that helps absorb other nutrients, which is great. Additionally, a cholesterol-free diet will prevent arterial clogging and ensure cardiovascular health.

Manganese and selenium help protect against diseases. Vitamins help lessen inflammation and promote the health of all organs, as does vitamin E, which prevents cancer and promotes healthy skin and eyes.

For guinea pigs, vitamin C is the most important nutrient; green onions contain this vitamin. By taking this vitamin, cavies are protected from diseases such as scurvy, which damages their fur, causes them to bleed, causes loose stool, Unclogged, Kidney failure and causes them to lose appetite.

Risks Associated with Onions

It is possible to really harm your guinea pig by just feeding it a little bit of onion. Onions usually cause your guinea pig’s eyes and nose to run when it first consumes them. Guinea pigs salivate more as well in most cases. It can be difficult to notice increased salivation and discharge in small guinea pigs due to their size.

You will see your guinea pig vomiting if they ate onions. Guinea pigs do not vomit normally. The effects of vomiting on animals aren’t the same as those on dogs, cats, or humans.

Your guinea pig’s health will worsen once it throws up. A guinea pig’s health can be adversely affected by eating onions in the following ways:


Urinary Difficulties

Onions contain a fair amount of calcium, and guinea pigs don’t require much of it. Ingestion of too much onion causes guinea pigs to ingest too much calcium, which can cause urinary problems such as bladder and urinary tract stones. Guinea pigs can experience severe pain from urinary difficulties, even though they are not necessarily life threatening.

Digestive Issues

The digestive system of guinea pigs is very sensitive, as you may already know. Sugar cannot be consumed at excessive amounts by guinea pigs. There is plenty of sugar in onions, even though they do not have a sweet taste, but they are way more sugary than guinea pigs should be eating. If you eat too much sugar, it can cause severe digestive problems as well as other health problems such as high blood sugar levels.



Onions can cause anemia, which is one of their more serious side effects. Onions damage red blood cells in guinea pigs, which causes respiratory problems and anemia. In addition to the anemia, the disulfides may also cause respiratory problems.



The consumption of onions can be fatal to your guinea pig if you don’t treat it or keep feeding it. If you think your guinea pig ate onions, even if it was just a little bit, we recommend that you take them to a veterinarian.


What To Do If Your Guinea Pig Eats An Onion

If you suspect your piggy consumed even a little onion, you should act fast. Even the smallest amount can cause severe harm to a guinea pig. Keeping an eye on immediate symptoms like discharge, nausea, and elevation should be the first step.

In spite of the importance of watching for these signs, you should not wait to consume onions. Call your veterinarian immediately if your guinea pig ate onions. A guinea pig’s health can quickly deteriorate as soon as it shows the first symptoms.

If your guinea pig has eaten green onion leaves, make sure it drinks a lot of water. Consult a veterinary doctor if you notice your guinea pig eating lots of green onion leaves and bulbs.

Onion poisoning cannot be treated by yourself. Your guinea pig needs to be examined by an exotic pet veterinarian who is reputable and trustworthy. Your pet will receive the best possible care from them.


Facts on Green Onions

Increasingly popular in this country is the mild flavor of green onions, Allium cepa. To preserve green onions, they must be stored properly and have a shelf life of seven to ten days. All onions, including the green onions, need full sun to grow optimally.

Calcium in scallions can lead to the formation of kidney/bladder stones. Bones need calcium to function properly. However, if cavies eat large amounts of this, it can form bladder/kidney stones, brain problems as a result.

Bloody urine, painful urination, and even fatal renal failure can result if this continues! Excess fibers will upset cavies’ stomachs, so don’t feed too much to them. Gas, diarrhea, flatulence, and loose stools are the symptoms.


Symptoms of onion poisoning in guinea pigs?

These are the reactions that guinea pigs may have when they become poisoned by onions:

  • Eye and nasal discharge
  • Mouth and eye irritation
  • Feeling weak and dizzy
  • Restlessness and walking around in circles
  • Symptoms of stomach upset
  • Diarrhea 
  • Breathing difficulty
  • Heart rate increases

Consult your guinea pig’s veterinarian as soon as possible if you see these symptoms in your pet.


Foods Guinea Pigs Cannot Eat

For various reasons, guinea pigs should not be given certain foods. While some foods may upset the GI tract or be toxic, others may contain too much fat or sugar, be a choking hazard, or lack nutrition. If you have questions regarding safe foods for guinea pigs, consult your veterinarian.

The following foods should not be fed to your guinea pig:

  • Caffeine-containing products (like chocolate)

Always keep an eye on your guinea pigs when they are out of their habitat and check with your veterinarian about which plants can be harmful to them.


Vegetables Can Guinea Pigs Eat

Fresh vegetables can also be fed to Guinea pigs every day. Your guinea pig will tolerate and like different amounts of vegetables each day. Large amounts of fresh produce can cause diarrhea in some guinea pigs, but some can eat it without any problems. 

In similar fashion, some guinea pigs prefer fresh vegetables over all else, even if provided with unlimited amounts. Guinea pigs can be offered vegetables on a daily basis as long as they are fed hay and pellets every day to ensure they get sufficient fiber and vitamin C. 

Introducing vegetables to your pet one at a time will help you determine whether they like and tolerate them. Greens grown organically are best. You can feed your pet guinea pig the following vegetables:

  • Unlike iceberg lettuce, Romaine lettuce contains many nutrients, not just water
  • A good source of vitamin C are the green, red, yellow and orange bell peppers
  • In addition to carrots, carrot tops have a high carbohydrate content.
  • Vitamin C is abundant in broccoli
  • The consumption of spinach in limited amounts may lead to bladder stones due to its calcium content
  • Artichokes
  • In limited amounts, Kale can cause bladder stones due to its calcium content
  • You should remove all stems and leaves from tomatoes
  • Squash 
  • Cucumbers
  • Brussels sprouts
  • Arugula, endive, chicory, radicchio, basil, and other leafy, dark green vegetables

Your guinea pig will benefit from the vitamins and minerals in these vegetables. Ensure the produce you feed your pet is washed thoroughly to remove pesticide residues. Also, cut up the produce into bite-sized pieces that are easy for them to handle.


Fruits Can Guinea pigs Eat

Guinea pigs should not be fed fruit as frequently as vegetables due to the high sugar content and potential upset in their GI tracts. It is good to give your guinea pig a few bites of fruit a few times a week as it can provide necessary vitamin C. The following fruits are healthy for guinea pigs:

  • Apples
  • Pears
  • Strawberries 
  • Blueberries
  • Kiwi
  • Bananas
  • Papayas 
  • Peaches
  • Cantaloupe
  • Oranges (in moderation, as they are quite acidic)

Offer bite-sized portions of all fruits to your guinea pig after thoroughly washing them.
