You shouldn’t give your rabbit any food that contains onion or any other member of the onion family.
They are toxic to rabbits and can trigger anaphylactic shock and hemolytic anemia.
Dizziness and an impaired immune system are additional side effects.
Never feed your rabbit onion or anything containing onion.
The same can’t be said for rabbits, though: onions are great for humans but should never be fed to them.
Your onions in the garden may need to be fenced off if your rabbit is free to run around there.

The Onion Family and Their Benefits
The common onion, also known as the simple onion, is related to other vegetables and herbs in the Allium family, including garlic, leek, and chive.
Humans can reap a number of health benefits from these herbs, including a strengthened immune system and reduced risk of disease.
Onions and related herbs are anti-inflammatory, beneficial for digestive health, good for the heart, and effective against cancer.
Minerals and vitamins, such as antioxidants, iron, calcium, phosphorus, folate, vitamins C and B6, and many others, are abundant in them as well.
But if onions are so good for people, can rabbits eat them, or are they toxic and bad for their health?
Why Are Onions So Dangerous?
There are many reasons why onions are bad for rabbits.
To start, they have a substance called thiosulphate in them, which is toxic to rabbits and will have an effect on the red blood cells.
Onion consumption has been linked to hemolytic anaemia, a condition in which red blood cells swell and rupture.
If your rabbit eats an onion, it may die, and there is little you can do to save it.
Since rabbits can’t vomit, they can’t get rid of anything that doesn’t sit well with them once they’ve eaten it.
In addition, the organosulfur in onions raise your rabbit’s susceptibility to absorb toxins through its digestive system.
Plus, even if the onion doesn’t kill your rabbit, the immunosuppressant effect could leave it more susceptible to diseases.
After consuming onion, your rabbit may exhibit drowsiness or weakness.
If your rabbit seems disoriented and clumsy, the onion may be to blame. Ingestion of large quantities of onion can result in severe anemia and even death.
Last but not least, if your rabbit is allergic to onions, it could go into anaphylactic shock.
Avoid giving your rabbit any onion at all, as even a small amount can be fatal.
What Should I Do If My Rabbit Eats Onions?
Despite precautions, mishaps can still occur on occasion.
Most rabbits will have enough common sense to avoid eating onions, but it is possible for this to happen if you leave your rabbit unattended with a potted onion or other enticing odor.
For example, if you make a sandwich with onion in it, your bunny may become interested in eating it.
A trip to the vet is in order if your rabbit has accidentally consumed onion.
While it’s possible that your rabbit won’t experience any of the symptoms listed above, the sooner you get it to a vet, the better its chances of recovery.
Even though it’s possible that your pet won’t experience any ill effects from eating a small amount of onion, it’s always better to be safe than sorry, so consult your veterinarian to find out what to do.
Don’t wait if your rabbit is experiencing dizziness or other distressing symptoms; if left untreated, it could die.
If you can’t get your rabbit to the vet right away, make sure it stays quiet and calm, and don’t feed it anything else.
Seek medical attention immediately and make sure it is not stressed in any way.
Can Rabbits Eat Other Kinds Of Onions?
You may be wondering if there are any other types of onions that are safe for your rabbit to eat besides white onions.
However, white onions, red onions, and green onions should all be avoided.
If you have a rabbit, please don’t put any of these in the rabbit’s bowl or leave them in the cage where it can get to them.
As a result of the toxins they contain, even a small amount of any of these could be fatal to your rabbit.
It’s also best to stay away from other relatives like garlic and chives.
They shouldn’t be given to a rabbit because they are unsafe.
What About Green Onions?
Rabbits can eat the fruit and vegetable parts of some plants, but can they eat green onions?
Should we feed our furry hopping friends green onions, or are they too toxic?
Unripe onions, or green onions, are simply onions that have not yet matured.
Although the bulb is harvested before it has had a chance to fully develop, it still contains the same compounds as fully grown onions.
Although the concentration of these substances in green onions may be lower, they are still present and should be avoided.
Are Red Onions any Better?
Unfortunately, there is no benefit to using red onions rather than white onions.
In spite of the fact that red onions may have varying concentrations of beneficial and harmful substances, nutrients, and minerals, they are still poisonous to rabbits and should never be fed to them.
Can I Give Any Part Of The Onion To My Rabbit?
No, a rabbit should not eat any part of the onion plant because they may all be toxic.
Onions, onion leaves, onion skin, and onion roots are all toxic to rabbits.
Never feed your rabbit any leftovers that you’ve prepared using onions. Don’t touch your bunny without first washing your hands.
Since rabbits shouldn’t be fed cooked food anyway, you should also never feed them any leftovers that might contain onions.
This is also true for salads, which may have ingredients like raw onion or garlic.
Make sure no onion or garlic was used in the preparation of any pre-made foods you intend to feed a rabbit or check the ingredients list to be sure.
If you are unsure whether or not the food contains onion, do not feed it to your rabbit.
What Are The Symptoms Of A Rabbit Eating Onion?
In addition to feeling lightheaded, you may also experience a lack of strength.
It’s possible that your rabbit will have trouble getting up and may end up lying on its side.
Rapid breathing or unresponsiveness are symptoms you might observe.
In addition to lethargy, other symptoms can include trembling, but sometimes you won’t notice any at all.
If you notice any of these issues, you should get medical help right away.
What Else Can Rabbits Have?
Fruits and vegetables are healthy for rabbits, and you can safely provide your bunny with about 10 percent of its daily caloric intake in this manner.
Pick only the foods you know to be secure, like
- Carrots and carrot tops
- Dark lettuces (e.g. Romaine lettuce)
- Green beans
Some rabbits may experience stomach upsets from even seemingly harmless foods, so it’s important to test a small amount of the food first.
Never feed your rabbit onion because it contains sulfites, which are toxic to rabbits.
It’s potentially fatal for your rabbit due to the combination of several different toxins it contains.
Keep your bunny away from the onion plants in your garden and the bunny’s cage.
