Do Rabbits Fart? Can Excess Gas Kill Rabbits?

Do Rabbits Fart?

Rabbits are cute, fluffy creatures that are often kept as pets. These little critters are known to portray similar characteristics to other mammals, but the question on many rabbit owners’ minds is” Do rabbits fart”?  And as funny as it may sound, the answer is: 

Yes, Rabbits do indeed fart. As a consequence of digestion, they release gas, just like any other living thing. This gas is sometimes referred to as flatulence or intestinal gas which is normally discharged from the rectum as a fart.

However, rabbit farts are generally less smelly and less noticeable than those of other animals, due to the nature of their diet and the makeup of their digestive system.

Do Rabbits Fart?

Like most animals, and certainly all mammals, rabbits do fart. Passing gas is an important part of the rabbit’s digestive routine because their gut bacteria create a lot of gas when breaking down the fibrous plant matter that they like to eat.

Rabbits’ digestive systems are designed to extract the maximum amount of nutrients from their food, and this process can produce gas as a byproduct. This gas is composed of a mixture of gasses, including hydrogen, methane, and carbon dioxide.

A study published in the Journal of Animal Science in 2015 investigated the effect of dietary fiber on intestinal gas production and passage in rabbits. The study found that increased dietary fiber resulted in higher production of gas in the large intestine of rabbits. Other studies have looked at the composition of the gas produced by rabbits and the impact of different diets on flatulence.

This behavior is seen as being perfectly normal because it is part of their natural digestive processes, much like humans and other animals.

Can Rabbits Fart

Yes, rabbits can indeed fart. Like many other animals, rabbits have a digestive system that produces gas as a byproduct of the digestion process.

This gas needs to be released from their bodies, and rabbits do so by farting. However, rabbit farts are typically not as loud or noticeable as those of larger animals, due to their smaller size and different digestive system.

Why Does A rabbit fart?

As for why rabbits fart, this is a common question that many people ask themselves. The truth is that there are a variety of reasons for this behavior. 

1. Diet

A rabbit’s diet plays a significant role in the amount of gas they produce. Rabbits are herbivores with a digestive system that is designed to extract nutrients from plant material. However, certain types of plants and vegetables can cause gas to build up in the digestive system, leading to farting.

Also, a diet that is high in carbohydrates or sugar levels, can lead to more frequent farting. Additionally, any changes in a rabbit’s diet or digestive health can also lead to an increase in gas production.

2. Stress

Just like humans, rabbits can experience stress and anxiety, which can lead to an increase in gas production.

3. Health issues

Certain health conditions, such as a gastrointestinal infection or blockage, can also cause increased gas production in rabbits. Briefly, You should know that rabbits tend to swallow a lot of air while eating, which can contribute to farting. 

How To Stop A Rabbit From Farting Excessively?

It is impossible to stop a rabbit from farting, and you certainly shouldn’t try to do so. If you manage to stop them from farting, you would only cause them a build-up of pressure and major discomfort. 

Farting is part of a rabbit’s natural behavior, so instead of looking for ways to stop them, it is advisable that you only help them reduce their farting to normal levels if it becomes excessive. You can do a few things to help reduce the amount of farting in your rabbit:

1. Feed your rabbit a high-quality diet

A diet rich in hay and low in sugary treats can help reduce gas production.

2. Introduce new foods slowly

If you need to make changes to your rabbit’s diet, do it gradually to give their digestive system time to adjust.

3. Provide plenty of water

Dehydration can lead to constipation, which can contribute to farting. Make sure your rabbit has access to fresh, clean water.

4. Monitor your rabbit’s digestion

Keep an eye on your rabbit’s bowel movements and consult with a veterinarian if you notice any changes. You could consider changing their diet if they’re eating fart-inducing foods such as broccoli, spinach, kale, cauliflower, and cabbage.

You can also give them medication like simethicone, which is usually the indicated treatment for abdominal discomfort caused by gas. By following these tips, you can help reduce the amount of farting in your rabbit and ensure they are healthy and happy.

Do Rabbits Fart Smell?

Rabbits have a relatively small anus which makes their fart often wholly silent, and you probably won’t ever realize that your rabbit just let one rip. Their farts are also very rarely smelly because of their natural diet. However, you will most likely smell your rabbit’s fart if its diet contains more protein.

Generally, animals (and people) who tend to have smelly farts eat a lot of protein, which isn’t a major part of a rabbit’s diet. However, if you suspect your pet’s flatulence may be causing an odor, consider visiting an experienced veterinarian who can provide an accurate diagnosis.

Additionally, providing a healthy diet for a domestic rabbit can help reduce any discomfort associated with digestion and result in fewer foul odors overall.

Does Farting Mean My Rabbit Is Sick?

No, farting doesn’t mean your rabbit is sick is a sign of a healthy rabbit. Farting is completely normal in rabbits as it is in humans. However, if your rabbit farts excessively, it means they are gassy and will require examination.

Plenty of factors play a role in how much and how often a rabbit farts. The diet is important, but so is the rabbit’s overall health and stress level. If your pet rabbit farts excessively, and maybe even has a runny stool, it’s a clear indicator that you need to take it to a vet.

How To Know When Your Rabbit Is About To Fart

Although this isn’t always the case, if you notice your rabbit raising one of its back legs, it could be that the rabbit is about to fart. Once a rabbit does this, you might notice a cloud of smelly air coming from the back end of the rabbit.

What Foods Cause Rabbits To Have More Gas?

Foods that are high in sugar, protein, and carbohydrates are most likely going to cause gas in your rabbit. A rabbit’s diet should contain foods like Hay that contain a high level of fiber, which is responsible for the effective functionality of a rabbit’s digestive system.

If your rabbit frequently gets gas, avoid giving it foods like pellets. Pellets aren’t essential for adult rabbits as they are for baby rabbits.  3 months after birth, a rabbit will no longer need the protein that pellets provide.

Keep in mind that an adult rabbit’s stomach can become bloated if it consumes excess protein. So you should be careful when feeding your adult rabbit pellets.

You should also be careful when feeding your rabbit fresh fruits and vegetables as they contain a high level of sugar and carbohydrate which are responsible for gas.

When feeding fruits or veggies, remember to always keep them at a minimal level and provide them with plenty of hay. These are examples of foods that may cause gas in rabbits;

How To Tell If A Rabbit Has A Gas

Like humans, rabbits exhibit some physical symptoms that show that they are capable of developing a gas. There are signs to look out for to know for sure that your rabbit has excess Gas.

  •  Gurgling stomach
  • Loss of appetite
  • Body temperature falls below 100°F
  • Lethargy
  • The stomach feels hard
  • Inability to excrete 
  • Teeth gnashing
  • Flatulence (gas)
  • poor body posture

Can Excessive Gas Kill A Rabbit?

Excessive gas is known to kill rabbits if not attended to at an early stage. If your rabbit develops excess gas buildup, it would cause great discomfort and distress. This would subsequently cause a decrease in appetite, which would result in GI stasis.

Bubbles created by gas in a rabbit’s stomach will clog its blood arteries. Blood will not flow freely throughout your rabbit’s body when this occurs. This condition is referred to as a gas embolism.

A gas embolism stops blood from getting to a rabbit’s vital organs. Your rabbit’s daily activities will be compromised if there isn’t enough blood getting to the brain. An untreated gas embolism will lead to organ failure and eventually result in death.

Additionally, gas can clog your rabbit’s digestive system which will lead to GI stasis (Gastrointestinal stasis). GI stasis occurs when food cannot pass a gas bubble to enter the digestive tract.

If your rabbit’s stomach contains any food that cannot be easily digested,  it will become uncomfortable as a result and will become reluctant to eat or drink. This will be fatal to your rabbits as they cannot go without food for more than 24 hours.


Though largely unnoticed by their seemingly docile and quiet nature, there are anecdotal accounts of rabbit farts, either through pet owners experiencing an unusual smell after interacting with their pets or through veterinarians conducting routine check-ups.

Rabbits don’t have a large anus and so their farts are tiny which makes them unnoticeable most times. To prevent excessive farting in rabbits, it is essential to maintain a healthy diet that is high in fiber but low in sugar and fat.

Additionally, providing a stress-free environment and regularly checking for any health issues can also help reduce farting.
