Can Rabbits Eat Corn? 7 Risks for Rabbits

Who would have thought corn would cause so much debate? Corn as a source of nutrition for rabbits is a contentious topic. Considering this, one might speculate as to whether or not rabbits can digest corn. In a nutshell, the answer is no, and the scientific justification is straightforward.

Most rabbits would eat corn if given the chance, but there are parts of the plant that are harmful to rabbits. But there are corn parts that are safe to eat. There’s a lot to analyze in this.

Here we’ll investigate the scientific rationale behind why rabbits shouldn’t eat corn. We’ll also investigate the dangers of feeding corn to your rabbit and discuss which parts are appropriate for consumption.

Can Rabbits Eat Corn?

No! Corn is toxic to rabbits.You’ll need some background knowledge on corn’s origins in order to appreciate why rabbits can’t eat it. The ancestor of corn is a grass called teosinte, so we’ll begin with that.

The ancestors of the large, sweet kernels of corn we know today can be traced back to central Mexico, but they look nothing like modern corn.

The genetic makeup of sweet corn has been altered as a result of thousands of years of domestication and selective breeding.

Therefore, corn hulls contain a complex polysaccharide that is indigestible to rabbits.

Why Rabbits Shouldn’t Eat Corn According to Science

The argument stems from the fact that some pet rabbit owners have fed their rabbits corn with no ill effects. However, the vast majority of veterinarians will advise you to refrain from giving corn to your rabbit.

Feeding corn to a rabbit can lead to fatal gastric dilatation and intestinal obstruction.

Corn kernel hulls have polysaccharides. According to scientific definition, polysaccharides are a type of carbohydrate commonly found in foods. It’s a carbohydrate, so it has starch, glycogen, and cellulose molecules.

Upon reacting with water, these molecules form sugars that prove fatal for rabbits.

The corn hulls are indigestible for rabbits. The rabbit’s digestive tract may become blocked, threatening its life.

Fumonisin is also present in corn and corn products. The mold, and fungi in general, produce fumonisin, a mycotoxin.

Mycotoxicosis can develop in rabbits if they consume moldy corn. When a rabbit contracts this illness, it wreaks havoc on their internal organs, particularly their kidneys and liver.

Rabbits may develop hepatic failure, gastroenteritis, and renal failure as a result of this. It’s worth noting that, like humans, rabbits can develop mycotoxicosis from eating too much corn.

Dangers of Corn for Rabbits

In normal circumstances, a rabbit’s digestive system can process hefty amounts of unprocessed plant matter. However, if a rabbit consumes something that it is unable to process, such as corn, it can have serious consequences.

The smallest amount of corn can cause fatal gastrointestinal stasis and intestinal impaction in rabbits.

Rabbits shouldn’t eat corn for any reason, but especially because it can cause them a lot of stomach trouble. You can see why below:

  • Sweetened with added sugars and “empty” carbohydrates
  • Mineral and vitamin deficiency; very low in quantity
  • Grown with pesticides, which can be dangerous for your rabbit.
  • Mycotoxins can be present even in the husks and cobs.

Nutritional Risks for Rabbits When Eating Corn

Nutritional considerations aside, rabbits should not eat corn for scientific reasons. Corn is a good source of both starch and fat.

Experts in the veterinary field warn that giving corn to rabbits can cause them to become overweight and cause a condition known as gastrointestinal stasis.


Corn should be avoided due to its high sugar content. Your rabbit may become obese if you allow it to gain too much weight. Overweight rabbits are prone to diabetes.

Digestive Issues

Carbohydrates and sugar are abundant in corn as well. Your rabbit probably won’t be able to digest it because of the high sugar content.

Corn will cause gastrointestinal distress, including bloating, gas, and diarrhea.

Corn, whether dry or fresh, is toxic to rabbits. We’ve mentioned before that rabbits have trouble digesting corn hulls, which can lead to impaction and blockages in the digestive tract. In this case, it’s imperative that you get emergency medical care for your rabbit.

In case your rabbit somehow gets into some corn, keep an eye out for any adverse reactions. Diarrhea, painful bloating, and gas are the symptoms of a negative reaction to corn.

Excessive itching and licking are common signs of an allergy. If you think your rabbit is having a reaction to corn, you should get it to a vet right away.

Cecal Dysbiosis

Cecal dysbiosis is a disease that can affect rabbits if they eat too much corn. Indigestible hay and grass are broken down by bacteria and yeast stored in the cecum.

Cecal dysbiosis is brought on by feeding a rabbit a diet high in starch, carbohydrates, and sugars.

Because of this, the bacteria in the rabbit’s digestive tract are unable to break down food properly.

Cecal Hypomotility

Rabbits may also have slower digestive motility if fed corn. Cecal hypomotility refers to the sluggish transit of food through the intestines.

Unfortunately, this causes the rabbit’s cecum and intestines to shut down, which poses a serious threat to the rabbit’s life.

Can Rabbits Eat Cooked Corn?

As a result of two factors, rabbits are unable to consume cooked corn.

Corn contains potentially harmful compounds that are not deactivated by cooking.

Rabbits can’t digest corn because it contains polysaccharides that are resistant to even the longest cooking times. Whether fresh, dried, or cooked, corn poses the same health risks to your rabbit whether fed fresh or cooked.

The digestive health of your rabbit will suffer if you feed it cooked food, which is reason number two.

In general, rabbits have a strong aversion to cooked foods. This goes beyond personal preference in terms of flavor:

Rabbits can’t properly digest food that has been cooked. The gut microbiome of a rabbit can become severely imbalanced if it consumes cooked food.

Which Parts of Corn Can Rabbits Eat?

Rabbits should never be fed any form of corn, including canned corn, frozen corn, baby corn, or popcorn. All rabbits, from adults to young ones, are included here. It’s not worth putting your rabbit’s health at risk or putting up with the anguish they’ll experience.

Do you want to know if rabbits can eat any part of the corn plant? The green, leafy outer layer of corn (the husk) is completely safe for rabbits to eat.

Rabbits, with their constantly developing sets of teeth, can find husks useful as chew toys.

Be sure to thoroughly wash the husks to remove any harmful pesticides and bacteria before using. The rabbit’s throat may become blocked by the long, silky hairs, so they should be shaved off as well.

The entire corn plant, from leaves to stalk, is edible to rabbits. Corn leaves are a great addition to a salad or other dish featuring greens. The corn plant stalk is a healthy treat for your rabbit because it is high in protein.

It’s important to remember that when corn plants reach maturity, they get very tough and can be difficult for rabbits to eat. Pick only the tender, green parts of the plant.

Proper nutrition is essential to the longevity of your pet rabbit. High-quality hay and plenty of water are essential components of a rabbit’s diet. Add some fresh greens to your rabbit’s diet every day, in the form of smaller portions.

Feeding your rabbit primarily commercial pellets is unhealthy. You should limit treats to no more than 5% of your rabbit’s daily calorie intake.

The diet of a rabbit must always include plenty of hay. Hay’s dietary fiber is great for your rabbit’s digestive system.

Since rabbits can’t digest starchy foods like corn, they need to supplement their diet with hay and greens to get all the vitamins, minerals, and fiber they need.

What to Do If Your Rabbit Eats Corn

Unfortunately, many rabbits prefer the sweet and starchy flavor of corn.

This, in combination with their naturally inquisitive personalities, makes rabbits a common culprit in the theft of forbidden foods.

In the event that you discover your rabbit has consumed corn, the first thing you should do is check for symptoms of indigestion. These include nausea, vomiting, a lack of appetite, and abdominal pain.

Make an appointment with your veterinarian right away if you notice any of these signs. If your rabbit has eaten indigestible corn, it may need medical assistance to properly pass the food.
