If they don’t eat or have an improper diet, it can lead to such issues, which causes diarrhea.

While it is easy to spot, you must still take the necessary measures to identify the problem. And the sooner you act, the better it is for your furry friend.

Causes of Diarrhea in Guinea Pigs

Before anything, you need to learn what is causing this condition in your guinea pig.

This will help you understand their condition and choose a suitable treatment method.

Here are some of the main reasons that might cause diarrhea in your guinea pig:

Diet Changes

The most common reason behind diarrhea changes is your pet’s nutritional intake and diet. Unlike humans, guinea pigs don’t need variety in their diet.

They like to eat the same thing every day, which keeps them healthy. A healthy diet for these animals includes hay and pellets fortified with vitamin C.

They also enjoy fresh vegetables and fruits. However, they should be a small portion of their diet.

You should always give your guinea pig pellets that are designed for them. Pellets designed for other animals may be harmful to them.

When the guinea pig eats more grains than grass, its stomach might get irritated. This can lead to digestive issues and diarrhea.

Improper Diet

If you make dramatic changes to a guinea pig’s diet or add too many new things, it may upset their stomach. An upset stomach can then lead to diarrhea.

Too many vegetables, fruit, or any other food that they are not accustomed to can mess up their system.

Moreover, you should avoid giving them certain foods.

Avoid feeding your pet rhubarbs, nuts, potatoes, human junk food, cabbage, broccoli, collard greens, etc. This can affect their digestive systems and lead to health problems.

Dental Problems

Dental problems might be an underlying reason why your guinea pig has diarrhea. This is because dental problems cause problems in chewing.

Hence, if the guinea pig does not chew their food properly, it can negatively impact their digestive systems. If you suspect dental problems, look for its signs.

Drooling and mouth sores can indicate dental problems. These problems may be caused by poor diet.

In such cases, you should take your guinea pig to the vet at your earliest.


In some cases, even stress from the environment may cause guinea pigs to have diarrhea.

New pets or children and unknown changes in the environment can all stress them out.

Even temperature changes can cause your pet to have soft stool.

Bacterial Infection

If your guinea pig is suffering from severe diarrhea, it could be due to a bacterial infection in the gastrointestinal tract. In such a case, you must take them to the vet immediately.

Some bacteria that can cause such a condition include salmonella, which is the most common. Others are E.Coli, Yersinia pseudotuberculosis, and clostridium.

Besides taking them to the vet immediately, you should also thoroughly clean their bedding. Such infections can be passed down to humans.
