So, Can Rabbits Eat Onions?
The answer is a big no-no. Onions and rabbits should be kept apart as much as possible.
Onions are a common vegetable found in every kitchen. So, it becomes more crucial to avoid onions and other harmful foods to keep them out of reach so that they stay healthy and happy.
Your rabbits can eat onions fondly if they somehow get their hands on them. But this doesn’t mean that you start feeding onions to rabbits. Remember that even a tiny bite of onion can cause serious health problems for your pets.
What Are The Dangers of Onions For Rabbits?

Whether it is green onions, red onions, white onions, or any other members of the onion family, onion toxicity remains the same for rabbits. Even wild rabbits get sick if they eat onion plants, stems, leaves, or skins.
Onions are part of the Allium family which also includes chives, sleek, garlic, etc. The risks associated with all of them should not be ignored. If anything happens, immediate veterinary consultation becomes necessary.
Presence of Thiosulphate
Onions contain compounds called Thiosulphate. Rabbits can’t simply digest them. Unlike humans, their digestive systems lack the necessary enzymes to break down this compound.
Therefore, when rabbits eat onions, the Thiosulphate stays in their stomach and can lead to serious health issues. Avoid feeding onions as soon as you find out, and keep rabbits away from vegetables like onions.
Hemolytic Anemia
Consuming onions can cause Hemolytic Anemia in rabbits. This condition damages their red blood cells, making it difficult for their bodies to transport oxygen.
Potential health issues your rabbit may suffer include weakness, rapid breathing, and a reduced appetite. These symptoms are severe, and you should seek veterinary advice immediately.
Digestion Issues
Onions can also upset a rabbit’s stomach, causing digestive distress. This might lead to symptoms like diarrhea, which can quickly dehydrate a rabbit.
Always monitor your pet’s health and avoid feeding them anything from the onion family.
What Happens If a Rabbit Eats Onion?
Following are some signs if you suspect your rabbit has ingested onions.
You may notice they seem disoriented or weak, like they can’t find their balance.
They might move unusually or not want to move much at all. They may also breathe rapidly or show no interest in their usual favorite foods and water.
What to Do If Your Rabbit Eats Onion?
We have listed measures you can take if your rabbit has eaten onions.
Immediate Action Is Crucial
If you see any of these signs after your rabbit has eaten onion, it’s crucial to act fast. Don’t wait to see if they get better on their own.
Take them to a veterinary care as soon as possible. The vet will ensure to keep your rabbit safe and healthy by following regular procedures.
Fresh Water
Ensure your rabbit has access to fresh, clean water. This helps to flush any toxins out of their system. Keep the water bowl full and close to them so they can drink whenever needed.
Calm Down Your Rabbit
It’s also essential to keep your rabbit calm. Stress can worsen health issues, so create a peaceful environment. Speak softly and avoid any loud noises or sudden movements around them.
Monitor Closely
Monitor your rabbit’s behavior closely and take notes. Observe any changes in their actions or appetite, as these details can be vital for the vet.
If your rabbit seems lethargic or shows any other concerning signs, make sure to mention these to your vet immediately.
Safe and Yummy Foods for Rabbits
Yes, onions are toxic to rabbits, but you should know which foods are safe for your bunnies.
Carrots

Rabbits thrive on carrots. They love the taste, texture, and everything about it. Mix carrots with other foods to prepare a balanced diet.
Leafy Greens
Another type of vegetable that rabbits love to eat is leafy greens. But not every leafy green is good for rabbits’ diet. It is better to give them in limited quantities; otherwise, they might become harmful to rabbits.
Hay
Hay is the main dish, making up about 80% of their diet. It keeps their digestive systems running smoothly and their teeth in check.
Add a sprinkle of fresh veggies for variety and some quality amount of pellets too. But these should be more like a side dish, not the main course.
Keep Onions Away From Rabbits For Their Health and Well-Being
Even eating a small amount of onions can lead to serious health issues for your bunnies
If you suspect that your rabbit has eaten some onion and is showing worrying symptoms, rush to the vet without wasting any time.
