Rats can eat all sorts of foods. They’re opportunistic omnivores, meaning they will eat whatever foods are available. However, that doesn’t mean that all foods are safe for them to eat.
Onions are toxic to rats. The toxic chemicals in onions are broken down in high heat. Therefore, if you feed your rat cooked onions, they should be okay. But rats don’t really need to eat onions, so we don’t suggest giving them any—not even cooked ones.
It should be noted that rats are unable to vomit. They physically can’t do it. This makes onions very efficient at killing them as they can’t expel the onions after they’ve eaten them.
Since rats can’t get onions out of their bodies, onions may be especially dangerous for them, even in small amounts.
Can Rats Eat Green Onions? What You Need To Know
Green onions, also known as scallions or spring onions, are a common ingredient in many dishes But is it safe for rats to eat them? Here’s what you need to know about feeding green onions to rats
Green Onions Are Toxic To Rats
Green onions contain compounds called disulfides and thiosulphates which are toxic to rats. These compounds can damage red blood cells and cause anemia.
While a small amount of onion likely won’t cause major problems, it’s best to avoid feeding onions to rats. Rats cannot vomit so they have no way to expel the toxins once ingested. Even small amounts over time can be dangerous.
The strong scent of onions normally deters rats from eating them. However, rats may accidentally ingest powdered or cooked onions mixed into other foods. It’s best not to take chances and keep all types of onions away from pet rats.
Health Risks Of Feeding Onions To Rats
Here are some of the potential health risks rats face from eating onions:
-
Anemia – The sulfur compounds in onions can damage red blood cells, leading to anemia. Symptoms include lethargy, poor appetite, and breathing trouble.
-
Gastrointestinal issues – Onions can irritate the digestive tract, causing stomach pains, vomiting, and diarrhea.
-
Organ damage – With repeated exposure, onion toxins may damage organs like the liver and kidneys. This can be fatal.
-
Respiratory issues – Onion fumes may cause nasal and lung irritation. Rats are sensitive to strong odors.
While a single small ingestion likely won’t cause major harm, it’s better to be safe than sorry. Completely avoid feeding any type of raw or cooked onion to pet rats.
Are Cooked Onions Safer?
Cooking onions reduces some of the harsh sulfur compounds, making them slightly less toxic. However, cooked onions can still pose risks, including:
-
Remaining sulfur – Cooking doesn’t completely eliminate the harmful sulfur. Some rats are sensitive even to small amounts.
-
High calorie – Cooked onions are often prepared with added fats and oils, increasing the calorie content. This can lead to obesity.
-
Low nutrition – Onions offer very little nutritional value for rats, even when cooked.
It’s best not to take any chances with cooked onion. The risks outweigh any potential benefits. Occasional tiny amounts may not cause issues, but feeding rats onions regularly is not recommended.
Can Rats Eat Green Onion Tops?
The green tops of onions contain the same toxic compounds as the bulbs, just in lower amounts. The toxins are present throughout the entire onion plant.
While green onion tops may be mildly less dangerous, they can still make rats ill. It’s better to play it safe and avoid feeding any part of the onion plant to rats.
Safer Alternatives To Onions For Rats
Rats don’t need onions in their diet, and the risks outweigh any potential benefits. Here are some healthier veggies and herbs to feed your rats instead:
-
Leafy greens – Kale, spinach, lettuce, bok choy, beet greens. Offer variety.
-
Other vegetables – Broccoli, carrots, bell peppers, zucchini, peas. Chop for smaller rats.

Fresh herbs – Basil, mint, cilantro, parsley. Excellent sources of vitamins.
-
Fruits – Blueberries, banana, apple, melon. Provide as occasional treats.
-
Sprouts – Bean sprouts, alfalfa sprouts, broccoli sprouts. High in nutrients.
When introducing any new foods, go slowly to check for any signs of intolerance. But these options are generally safe and provide health benefits lacking in onions.

Are Cooked Onions Okay for Rats?
The cooking process reduces the number of toxins in the onion. Rats are allergic to the sulfur in the onion. Cooking removes much of it from the bulb, making it much safer. This substance is also why raw onions smell so strongly.
Therefore, cooking onions reduces the chance that it’ll harm your rat and may encourage them to eat them. However, some rats are sensitive to even a little bit of sulfur in the onion. These rats probably won’t eat onions no matter what you do.
If your rat sneaks some cooked onions, you likely don’t have anything to worry about. There isn’t enough sulfur in these onions to matter much!.
However, cooked onions are often very high in calories. They are usually cooked in additional oil and fat, increasing their fat content substantially. For this reason, we don’t necessarily recommend them as a snack.
The high fat content can quickly lead to obesity if they are fed regularly.
We also don’t recommend these onions for rats that have liver problems or are already obese. Let’s not make their current situation even worse!.
Is Onion Toxic to Rats?
Onions are very toxic to rats. They won’t kill them instantly, but they will make them very sick. A rat would have to eat a lot of onions to be killed, but that doesn’t mean that one or two bites are okay.
Onions are likely to make your rat very sick. People shouldn’t give their rats onion, not even a little bit. It might cause them to die.
Rats that eat an onion once aren’t likely to diet or feel many long-term effects. However, over a long period, onions can quickly kill rats. Therefore, they should not be part of your rat’s diet in the least.
The onion’s strong smell typically puts off rats. Therefore, they usually don’t eat onions. The only occasions where rats may happily eat onions are mixed with something else that they love. In these cases, the good smells may cover up the onion, and the rat may accidentally eat it. A rat may also ingest onions in their powdered form (which are often found on seasonings).
This is one reason why onions aren’t perfect for pest control. Rats typically know they shouldn’t be eating it and avoid it.
However, the smell of raw onion does make a good repellent. Anecdotally, some rats may avoid an area if it smells like onion.
We don’t recommend keeping rats in the kitchen while you cut up onions. They’re likely not to appreciate the smell very much.
It’s always a good idea to keep your pet rat out of the kitchen nonetheless. It’s possible that rats could get sick or hurt from other things on the kitchen counter besides onions. Furthermore, allowing a rat (even a pet) into your kitchen poses significant hygiene risks. As such, it’s best to not allow them into your kitchen at all.
