8 animals that eat their own poop

In recent months, unusual wildlife behaviours have been trending across social platforms, especially topics that challenge what we normally expect from the natural world. One such behaviour that always grabs attention is animals eating poop.


While the idea may sound uncomfortable to many of us, it is an essential routine for several species. For them, this is not a strange act but a practical solution that supports digestion, nutrition and early development.


Experts describe this behaviour as coprophagy. When an animal only eats its own droppings, the practice is known as cecotrophy. Both are part of nature’s way of helping animals make full use of the food available to them.


Here is a look at eight animals that depend on this habit and the reasons behind it.

Mice and other small rodents such as hamsters, guinea pigs and chinchillas regularly eat certain types of their own droppings. They produce two kinds of waste, and one of them is soft, moist and packed with nutrients. This soft pellet forms inside the large intestine and contains vitamins, proteins and healthy bacteria.

By eating it again, mice can absorb nutrients that their bodies could not take in the first time. This process helps them make better use of their food, which is important because their small bodies need a constant supply of energy. For rodents, this habit is simply a natural part of staying healthy.

Mountain beavers also produce two different kinds of droppings. One type is dry and low in nutrients, while the other is soft, moist and rich in vitamins like B and K. The softer droppings also contain amino acids that support their growth and bodily functions.

Since mountain beavers mostly eat simple plant material, their food is not very nutritious. Eating the softer droppings gives them a second chance to absorb everything useful from their diet. It helps them stay healthy even though their food options are limited.

Capybaras, the world’s largest rodents, often start their mornings by eating droppings they produced the night before. Their diet is mostly made up of grasses, which are tough to digest and low in nutrients. When capybaras digest grass the first time, bacteria in their gut begin breaking it down, but the process is not complete.

During the night, microbes continue working on the food inside their digestive system, enriching the material with more protein and nutrients. By eating the droppings in the morning, capybaras get a more nutritious second round of food. This helps them maintain good health despite eating mostly rough plants.

Rabbits and hares face the same challenge; their diet consists mostly of grass, which is difficult to break down. Their bodies produce special soft pellets called cecotropes shortly after eating. These pellets contain proteins, minerals and vitamins that were not fully absorbed.

Rabbits and hares immediately eat these soft pellets to get all the nutrients they missed the first time. This behaviour is so important that without it, they would quickly become weak, because their bodies depend on this second digestion to stay nourished.

Woodlice, commonly found under rocks and logs, also eat their own waste. Their diet mainly consists of decaying plants and dead organic matter. Even after digestion, some nutrients remain in the droppings.

By consuming their waste again, woodlice improve their nutrient intake and make sure nothing goes to waste. This recycling behaviour also helps break down organic matter in the environment, making woodlice important contributors to soil health and natural decomposition.

Dung beetles rely entirely on animal dung for survival. They feed on it, shape it into balls and even use it as a nursery for their eggs. After laying eggs inside a dung ball, the beetle buries it underground. When the larvae hatch, they have immediate access to food.

For dung beetles, dung is not disgusting; it is a source of nutrition, a home and a part of their life cycle. Without dung, they simply cannot survive.

Baby elephants are born without the gut bacteria needed to digest tough plant material. These bacteria are essential for breaking down leaves, bark and grasses. To get these good microbes, young elephants eat the fresh dung of their mothers or other elephants in the group.

This helps them build a strong digestive system early in life. Adult elephants sometimes eat dung too, especially when they are unwell or need extra nutrients. The dung contains partially digested plant matter that can give them a nutritional boost.

Though humans may find it unpleasant, poop eating is actually a clever survival strategy in the wild. It helps animals:

Absorb more nutrients that their bodies missed the first time

Maintain a healthy gut with the right bacteria

Make the most of a poor or hard-to-digest diet

Save energy by not wasting valuable nutrients

For many species, this behaviour is essential for survival.

In nature, nothing goes to waste. These animals show how smart and efficient wildlife can be, using every available resource to stay healthy and survive in their environment.
