Why do guinea pigs eat their poop? The Answer Will Shock You!

It might sound gross to some people, but guinea pigs do eat their own poop. But would they do so? Why do guinea pigs eat their poop? As a curious guinea pig owner, I decided to do some research and what I found was something I had never heard of. 

Guinea pigs eat cecotropes, which is a soft stool produced by them. Eating these has various benefits, while for an adult, it helps in the absorption of extra nutrients from it; for young ones, it acts as a starter for good bacteria in their gut before they switch from their mother’s milk to solid foods. 

Guinea pigs in the wild didn’t have an abundance of food with them. So, they developed a habit of absorbing the leftover nutrients by consuming their poop. But what they eat is not precisely their regular poop but cecotropes. In fact, it is very unlikely for a guinea pig to eat their regular poop. 

Guinea pigs typically have two types of poop. One is fecal poop, which is hard and black in color. The other one is called caecal poop, which is soft and yellowish in color and usually is covered in some sort of mucus.

Let us dive deep and learn a little more in detail to understand what exactly is cecotropes, how is it different from regular poop and why do guinea pigs eat it?

Guinea pig Cecotropes

First, let us begin by understanding what exactly Cecotropes is? Cecotropes are soft, nutritious substances produced by the guinea pigs.

Although many people confuse it with poop as both come out from the same spot, it’s not precisely a poop. Then what is it? To understand that the first thing you need to understand is how it is formed.

The process is a little complicated one, but I have simplified the terms so that you can understand it pretty quickly. So, let’s find out!

Why do guinea pigs eat their poop?

As guinea pigs eat their food, the food passed through the esophagus and reaches the intestines. Here the walls of intestines break the food partially which is again pushed towards a pouch called cecum.

Here the good bacteria of the gut further breaks the food down into simple sugar form, which is absorbed by the cell in the form of energy. What remains is soft, moist pellets known as cecotropes.

These pellets still hold lots of nutrients because the bacteria are still unable to extract all the proteins and Vitamins from the food. However, these pellets continue their journey through the intestines and out to the world where guinea pigs are ready to gulp them back in.

When our guinea pigs eat it again and pass it through their intestines and re-process the food, the food breaks down completely, allowing the guinea pigs to rip all the nutrition out of it.

These cecotropes are full of Vitamins and Minerals which guinea pigs need for living healthy. If a guinea pig is prevented from eating cecotropes or is by any means unable to eat it, then they will suffer from malnutrition and may eventually pass away due to the same.

The entire process of producing cecotropes and eating it is referred to as guinea pig coprophagy.

Since guinea pigs are herbivores and they eat a plant-based diet that has a lot of fiber in it, the food doesn’t get entirely digested at once. So to rip all the nutrients out of the food, they need to ingest the food again. I hope the next time you see that you will not feel gross again!

Is it normal for a guinea pig to eat its poop?

Yes, it is entirely natural for guinea pigs to eat their caecal poop. Guinea pigs need to eat their caecal poop to get essential Vitamins from it.

Do all guinea pigs eat their poop?

Yes, In general, all guinea pigs will eat their Caelcal poop. In fact, it could be a problem if they are not eating it. As they can suffer from serious health diseases and malnutrition. Some of the common benefits of eating their caecal poop are:

What does it mean when guinea pigs don’t eat their poop?

There can be some situations when guinea pigs are unable to consume their caecal poop. Older guinea pigs often lose their muscle tone near their anal area, which can lead to impaction in them.

In such circumstances, guinea pigs are unable to excrete their poop and Cecotropes, which can be an emergency. If such a situation arises, you must rush your guinea pigs immediately to a vet.

The vet might need to manually clean and remove the excreta out. In the meantime, you must supplement your guinea pig’s diet to prevent malnutrition. Your doctor may recommend some vitamin supplements along with toasted wheat germ.
