Guinea pigs fart occasionally, and it’s usually not something to worry about. Farting is a normal physiological reaction. It can be a sign of digestive issues caused by certain antibiotics.

A sudden change in the diet can also lead to this issue. In case of excessive farting and other signs of digestive issues, make sure you take your guinea pig to a veterinarian. 

What Do Guinea Pigs Fart Sound Like?

It usually sounds like a little puff of air, just like a human small fart. If a guinea pig farts, it doesn’t usually smell, because the small fart does not affect the surrounding air. 

A fart from your guinea pig may not even sound like farting. You may just notice vibrations, rumblings, or light puffs of air

However, if it smells nasty, it can be an indicator of a serious problem in your piggy’s digestive system. If ignored, the issue can be fatal. So, take your piggy to a vet if the fart smells bad.

How often Do Guinea Pigs Fart?

Guinea pigs have a sensitive digestive system. Their stomachs become upset pretty easily. If your piggy farts occasionally, don’t worry about it.

However, if farting is regular and excessive, visit a vet immediately. Excessive farting can be a sign of bloating or constipation, which can be fatal for these adorable rodents.

Digestive problems and bloating can make your guinea pig fart. Farting has many causes including an abrupt diet change, being on antibiotics or feeding too many green veggies.

An Abrupt Diet Change

A sudden change in your guinea pig’s diet is one of the most common causes of bloating, which makes the animal fart. An imbalance in nutrition can lead to more serious problems, such as chronic diarrhea. 

If you introduce a new diet, do not rush. Make the transition slow. Plan a balanced diet and stick to it.  

By all means, steer clear of dairy products and beans, because they can cause severe digestive complications in guinea pigs. 

Avoiding cruciferous vegetables altogether is not a good idea either. It is okay to feed these foods occasionally. Notice how your piggy responds to these foods and make a decision accordingly. 

Your guinea pig’s primary food should be hay, which is good for the digestive system of rodents. Steer clear of big pellets with cereals or corn, because guinea pigs find them hard to break down.

Being on Antibiotics

Another common cause of farting in guinea pigs is being on antibiotics. If your guinea pig is taking antibiotics, their gut bacteria may be out of balance. This can lead to gas and other digestive issues. Do not use antibiotics without consulting a veterinarian.

Feeding Too Many Green Veggies

If you’re feeding your guinea pig too many green veggies, this could also be the cause of their farting. While greens are a healthy part of a guinea pig’s diet, too many can lead to gas and other digestive issues. If you think your guinea pig is farting too much, cut back on the greens and try another type of food.

If your guinea pig’s diet is the issue, you can introduce new foods gradually or soak their hay in water for a few minutes to help with digestion. If you think your guinea pig may be sick, take them to the vet for a check-up.
