Do Guinea Pigs Fart (And When To Worry)

Guinea pigs may be one of the most adorable and cutest pets you can have. They have many appealing and interesting aspects to them. And they also make all kinds of noises. They produce squeaky sounds, gnarly sounds, and grunts.

But do guinea pigs fart? In this article, we will tackle why guinea pigs fart, its causes, and other related information.

Do Guinea Pigs Fart?

Yes, guinea pigs fart. And this is completely normal. Guinea pigs have a similar digestive system to us, humans. So farting is also normal for them.

Much like humans, they react to whatever food they consume. And certain food sources would cause bloating and gases to them. This results in guinea pigs farting.

Albeit farting is normal to guinea pigs, there is a certain rate at which we can consider this normal. Farting occasionally is fine; however, when your pet farts irregularly, there may be something wrong with it.

Guinea pigs are not capable of passing gas like humans. Because of this, there is a tendency that gases can build up in their digestive system. When that happens, the guinea pigs may feel stressed and uncomfortable.

The digestive system process of guinea pigs begins at the mouth when they are chewing the food, down to their throat, and then to their small intestines. It is where most of the vitamins and nutrients of the food they eat are absorbed and then forwarded into the blood vessels. When this process is done, the food then goes into the caecum, where the remaining nutrients are further absorbed, and then the food starts moving towards the large intestine.

It is in the large intestine where the fermentation process begins. Intestinal gases are produced during the fermentation process. From the caecum, these gases are then forwarded into the colon. For humans, we can expel these gases. However, guinea pigs cannot do so.

How Often Do Guinea Pigs Fart?

Just like humans, guinea pigs fart now and then. Also, there is actually no reason to be worried about that. However, when they do fart excessively, then you must not leave it unchecked.

Guinea pigs swallow air when chewing food. Combined with the intestinal gases formed during digestion, this causes the guinea pigs to fart normally.

Some foods cause farting more often, so owners should be wary of feeding them too much of these food sources. Like humans, if guinea pigs eat too much or consume a lot of foods that can cause gases, it will lead to flatulence.

Similar to humans, guinea pigs fart differently from other guinea pigs too. What is important is that we know how often our pet guinea pigs fart normally. From there, we can then track if they are farting excessively or if they are not farting regularly.

When Is Farting In Guinea Pigs The Sign Of Something More Serious?

When your guinea pig farts more than usual, it may be a sign that something is wrong with it. Because guinea pigs cannot pass gas as we humans do, gas may be accumulated, and it could lead to bloating.

People experience bloating too. When you don’t let the gas out intentionally or a medical issue that prevents you from doing so, you tend to be more bloated, and your stomach would hurt. Your appetite drops down, and you start to malfunction. This is also true when it comes to guinea pigs.

Bloating and gas build up in guinea pigs.

Bloating is caused when there too much gas builds up in the intestines. When left unchecked, this could prove to be fatal. There are other symptoms of bloating aside from farting.

One symptom that is easily noticed is a swollen belly. Check your guinea pig and see if it has grown wider in the area near the rib cage. If it is, then that means that your guinea pig is likely has a swollen belly.

Guinea pigs can get a swollen belly from eating, and that is okay. However, if the swell has lasted for more than 2 or 3 days, then you should visit the vet. It is most likely that your guinea pig is bloated and has a lot of gas build-up that needs urgent attention.

When your guinea pig is bloated, you will also notice other symptoms like reduced appetite or doesn’t eat at all, it is getting weaker, it becomes restless and moves a lot more than usual, it starts breathing heavily for no reason, and you will notice an irregular bowel movement or sometimes, it stops its bowel movement.

As a responsible guinea pig owner, you must be able to track its food consumption. If it starts eating less or stops eating at all, then you should go to the vet for a check-up.

Try picking up your guinea pig and check its breathing. Breathing should be normal. If it is breathing heavily, then it is a sign that you should visit the vet.

Intestinal Twisting or Volvulus

This is a rare condition for guinea pigs, but definitely, something guinea pig owners should know since this is a severe condition. Intestinal twisting or volvulus happens when the intestines twist irregularly and cause blockage in the intestines. This is a very serious medical condition since it disrupts the digestive system of your pet guinea pig.

Intestinal twisting can be fatal if untreated or left undiagnosed for a long time. It is commonly triggered by some viruses, bacteria, parasites, or hairball infection. Some research claims that certain foods can trigger volvulus and excess gas that will cause farting.

It is therefore extremely essential to take note of the farts of our guinea pigs. If it farts occasionally, then there is nothing to be worried about. However, if it farts several times in a single day, do not hesitate to visit the vet.

What Foods Make Farting Worse?

There are many causes as to why guinea pigs fart. This includes the air they take in when they chew the food, the natural intestinal gas they produce, and of course, the food that they eat.

Many foods cause farting in guinea pigs.

That is why, as pet owners, you should be knowledgeable about them, and you should monitor what your pets are eating and that they are eating it in the right amount. Below are some foods that cause gas build-up.

  • Broccoli
  • Cauliflower
  • Collard Greens
  • Radicchio
  • Bok Choy
  • Peppers
  • Cabbage

The foods listed above are very hard to digest, especially when served raw. Although most of them are rich in fiber, they also prove difficult to digest and thus cause gas build-up. These foods have nutrients essential to your guinea pigs, so you should let them eat some from time to time; however, make sure you give it to them in adequate amounts.

Much like us human beings, guinea pigs also differ from one another. Some guinea pigs may be more susceptible to gas build-up than others, and some might be more resistant. As an owner, you must be sensitive to your guinea pig’s reaction to the food they eat. Sometimes, food that is healthy for them can cause gas to build up even in small amounts.

Another thing to be wary of is beans and dairy. These foods are known to cause excessive gas build up in guinea pigs. Make sure that you don’t accidentally feed them any of those.

Most guinea pig owners feed their pets with hay, and this is good since hay is rich in fiber that is essential for good digestion. However, there are other nutrients that your pet needs and is not present in hay. It is always a good idea to mix your pet’s diet every once in a while, just as long as it is in the right amounts.

Water is also very essential for good digestion. Ensure that the guinea pig has a clean water supply daily as water helps flush out unwanted food that remains in the intestines.

What Does It Mean When Your Guinea Pig Stops Farting?

We all know that excessive farting is a symptom of something bad. However, the same is also true when your guinea pig isn’t farting at all. It means that all the gases are stored inside its stomach and aren’t going out, and that is a very bad sign.

Complete stoppage of farting is a symptom of internal twisting. Because of volvulus, the gases get trapped inside, making your pet bloat. If you did not hear your pet fart for several days, you must immediately visit your vet. As mentioned above, volvulus is fatal when left unchecked.

Feeding your pet with high fiber foods can help boost his digestive system, so it is highly recommended that you do so.

Therefore, excessive farting is bad, and no farting is bad. As a responsible guinea pig owner, you must be able to monitor the regularity of your pet’s fart.
