Corn or maize is a cereal grain that is considered a staple food in many countries. Aside from being grounded into cornmeal for human consumption, it’s also made into animal feed.

Can rabbits eat corn on the cob?

Eating corn on the cob can cause fatal side effects to your pets. Corn seed is covered in a shell or coating called a hull. This part of the corn contains complex polysaccharides that rabbits can’t digest. And because rabbits cannot vomit, the corn stays inside the stomach unchanged. It leads to constipation and abdominal pains. In severe cases, the undigested corn blocks the digestive tract, which can lead to death

Corn cobs also pose risks like corn kernels. Rabbits mustn’t be fed corn cobs. Aside from having no nutritional value, corn cobs can also cause intestinal impaction

This feeding tip is a key part of taking proper care of your rabbit.

What are the potential risks that rabbits get when eating corn?

There are many health risks in letting your rabbit eat corn in any form. This is why it is not recommended by veterinarians. But if you are still planning on incorporating it into your pet’s diet, you should know what you will be facing.

Here are what happens when you feed your rabbit corn.

Corn can be a choking hazard

While rabbits have an amazing ability to nibble and chew on their food, field corn is very hard. For the most part, they bite it off swallow the kernels whole. Small and younger rabbits can easily choke on these.

Cecal Diabolysis

Rabbit feces have two forms, hard pellets, and cecotropes. Rabbits eat the cecotropes which may sound gross but are completely normal and healthy even.

Cecotropes are soft and are produced in the cecum, a fermentation pouch in the digestive system. In the cecum, there is a colony of good bacteria and yeast that breaks down indigestible fiber from grass and hay. This forms into essential nutrients and fatty acids that are then coated and excreted in the anus. Rabbits then eat this and the nutrients are reabsorbed in the stomach and intestines.

If a rabbit eats a healthy diet, these yeast and good bacteria thrive and produce healthy cecotropes. Rabbits who do not eat their cecotropes are missing a lot of essential nutrients.

When rabbits eat corn, the sugar and starch in this food will cause an imbalance and chaos in the cecum. Yeasts that love sugar will go wild.

On the other hand, the starch which the rabbit’s stomach cannot digest will get stuck in the intestines. It will continue to ferment and will encourage the growth of harmful bacteria.

These result in cecal diabolysis. One sign of this disease is feces that appears as dark puddles of smelly liquid.

Gastrointestinal (GI) Statis

Gastrointestinal stasis is one of the major risks of feeding corn to rabbits. GI stasis is caused by an imbalance of digestive flora, which causes the intestines to seize.

When rabbits eat corn, they can form an immediate blockage in the gut. A small amount of corn that gets stuck will also catch more and more food every meal and cause a plug to form over time.

When these scenarios happen, the digestion goes into stasis or stops. The food that gets stuck will cause the growth of harmful bacteria that will cause bloating and abdominal pain. Rabbits will quickly lose their appetite and refuse to take in food and drink water.

If Gi stasis is untreated immediately, it could lead to fatal results. In most cases, surgery is needed.


Corn is rich in sugar and starch, which causes quick weight gain in rabbits. Eating corn once or twice a week can still lead to obesity.

Obesity can lead to secondary health problems for your pet, like arthritis, heart diseases, and liver problems.

Sudden weight gain will also result in an inability to groom itself, unformed cecotropes, joint pain, and nutritional deficiencies.

What are the contents of corn that can be harmful to rabbits?

While corn offers benefits, the risks are greater. Here are the contents of corn that are potentially harmful to your rabbit’s health derived from recent posts in medical journals.

High Carbohydrates

Carbohydrates help in growth and provide energy for a bunny. Corn, however, contains an average of 18.7% of carbohydrates which is a lot. Feeding rabbit corn can overload its cecum and cause stomach upset, diarrhea, and other digestive problems.

In addition, excessive amounts of carbohydrates prevent the production of molitin. Molitin is a substance that aids in the smooth flow of food in the gut.

Low Fiber

While corn is high in calories and carbs, it’s relatively low in fiber which is what a bunny needs.

A rabbit needs 18-25% of fiber every day. Filling them up on corn will decrease the amount of hay they eat. It will reduce their fiber intake.


Mycotoxins are harmful substances released by fungi that grow on corn and other grains. Corn may contain aflatoxins and fumonisins. Even small amounts of this are potentially dangerous when ingested by humans and animals.

Can you give corn cob to a rabbit as chew toys?

Rabbits have open-rooted teeth, which means that their teeth are ever-growing. The incisors of a bunny can grow between 1.3-3mm per week. Long-time pet owners know this, but some may still be unsure whether con cobs are safe to give as dental toys.

The answer is no. Giving rabbits corn cobs as dental toys creates more problems. Corn cobs are dull and soft. They do not have enough abrasive texture to effectively wear down the teeth of a bunny. Most likely, your rabbit will bite off and swallow pieces of corn cobs that can get stuck on the throat or intestines.

To avoid choking and stomach impactions, give your bunny hay or vet-recommended dental toys to help wear their teeth down.
