Do Guinea Pigs Fart?

Guinea pigs tend to make several noises such as squeaks, grunts and gnawing sounds. Apart from these you might have noticed a different sound with a smell that you didn’t expect to hear from your guinea pig which makes you think do guinea pigs fart?

You might not be sure whether your guinea pig farted when you hear the sound and you might be worrying about your pet’s health wondering there is something wrong with your guinea pig.

Do Guinea Pigs Fart?

The answer is yes, guinea pigs fart and it smells bad when they do it.

This is a normal phenomenon and natural thing but too much gas can be dangerous to your pet. Guinea pigs’ digestive system is generally similar to human digestive system and usually guinea pigs are not able to pass larger quantity of gas. Too much gas can cause a life threatening health issue called “guinea pig bloat”.

Most of our domestic pets such as dog and cat may fart and with guinea pigs, let’s find out what causes it and things to do if it becomes a health issue to your piggy.


In small intestines, initial digestion starts and blood vessels are capable of absorbing all the essential nutrients at this stage. Next, the food is reaching caecum and any remnant nutrients will be absorbed. Then food moves towards the large intestine to begin fermentation.

This fermentation process generates intestinal gas and this gas is passed to the colon from the caecum. Humans usually pass this gas but in guinea pigs these gases tend to stay in the colon as it is not able to move forward. Anyhow guinea pigs are unable to pass the gas as humans do.

The Correlation Between Bloating And Gas

Each mammal usually has intestinal gas to a certain amount which is produced during digestion. In intestines the extreme gas increases. When mammals consume foods, the digestive juices come into action and gases are developed. When consuming foods, air is also ingested and sacks of air are trapped in the foods as mammals chew on them. As a result of this air ends up in their little stomachs.

This gas combines with the gas which is already produced during the digestion and it becomes large quantity of gas inside the stomach. If there is no way to force out the gas it can quickly turn into a great problem which can risk your pet’s life.

As I mentioned earlier guinea pigs are unable to pass the intestinal gases as they wish, so the excess gases could easily cause bloating which is very painful to your guinea pig and further it could be a fatal situation to your pet. Intestinal gases play a main role in guinea pigs to suffer from bloating.

When a guinea pig is suffering from bloating, its belly would become bloated and would lead to a gut-wrenching pain. Intestinal twisting is another cause of this and it’s way too dangerous. Intestinal twisting happens when intestines twist which further cause intestinal blockage. This condition is very critical and usual digestion process can be disrupted.

If your guinea pig is suffering from intestinal twisting, you need to treat it as soon as possible otherwise it could be fatal to your pig. Viruses, bacteria, parasites and hairball impaction could be the triggers to this condition. According to some researches excess gas and certain food can produce this condition. You need to observe your guinea pig closely for any unusual changes. If your pet passes an occasional fart rarely, there is nothing to worry but if your piggy farts few times a day it’s time to seek medical advice.

The discomfort in guinea pigs is very painful as bloating arises. When organs are compressed due to excess gas, guinea pig bloat would take place. As a result of bloating gut motility will be severely slowed. This is fatal condition to your pet if not treated in time.

In overall, bloating can be considered as an ordinary problem in guinea pigs that avoids food from shifting through the gastrointestinal tract which could be a harsh state. It is called GI stasis and it would lead to a visibly bloated stomach.

Causes Of Bloating

Gas is produced in digestive process and it’s normal but the trouble begins when ordinary digestion is disturbed. Look out for these causes of excessive gas in guinea pigs.

  • Food

Food is the number one in the list of bloating causes. An unsuitable diet can definitely cause gas in your pet. Usually a high sugar diet or a high carbohydrates diet can easily cause gas in guinea pigs.

  • Sudden changes in guinea pig’s diet

The main things in a good guinea pig diet are balance and reliability. Due these facts sudden changes in diet can cause disorders in guinea pigs’ sensitive digestive system. When you change your pet’s food, its digestive system would take weeks to get use to it. This new food will surely cause gas in your pet.

  • Surplus of fermentable vegetables

Cabbage family vegetables such as Brussels sprouts, kale, cauliflower, red cabbage, white cabbage and too much fresh herbs and sweet fruits can cause gas in guinea pigs.

  • Wet, cold or rotten foods

Water and food must be in good condition to consume to prevent the risk of fermentation.

  • Too much food intake

Excessive food intake can produce gas and further it could lead to farting.

  • Dehydration

Your pet’s intestines could become dry if it doesn’t drink enough water.

  • Quick ingestion of food

Sometimes greedy guinea pigs tend to eat quickly. When they are doing that they swallow air with food which cannot be passed later. This occurs when your guinea pig eats too much or from the foods which cause flatulence.

  • Stress

Stress can be the reason for many diseases. Stress could stimulate the contractions of the intestine and that could lead to bloating. Thyroid gland can be directly affected by any sort of emotional stress. This emotional stress would accelerate the activity of the thyroid gland and that will produce gas ergo as a result of over stress.

  • Antibiotics

If your furry babies are taking antibiotics guinea pigs fart is an ordinary side effect. Good bacteria in guinea pigs’ gut are destroyed by the antibiotics. Further this could result loose stools and gas for several days.

This problem can last till their body gains the balance of bacteria levels. If you are providing antibiotics to guinea pig, it’s better if you can provide a probiotic such as Benebac so the good gut bacteria can be built to help with the farts and digestion.

  • Dairy products

As well as for humans guinea pigs find it hard to digest dairy products. As you might aware a young cavy relies on mother’s milk but as it age dairy products can cause digestive issues in them.

This is very rare and includes surgery. Bloating can repeat several times in lifetime. Bloat can be treated with medicines but prognoses are hard to determine. Once this happens, vets can treat the situation but there is no guarantee that bloats will never return. According to the researches only 20% of guinea pigs would suffer from this condition.

Non invasive procedures

Non invasive methods include anti gas medication in combination with antibiotics to restore the ordinary intestinal function. Depending on the situation some veterinarians prescribe either anti gas medications or the antibiotics. As bloated belly is painful, pain medications are prescribed more often.

Medications such as meloxicam and carprofen are given to get a relief from pain and it is very important in curing GI stasis. Drugs such as cisapride and metoclopramide help in emptying the intestine elevating intestinally, stomach motility and gastric movements.

Antibiotics should be given to prevent the bacterial growth.
