What animals eat other animals feces?

Answer 1

Animal digestion is not always complete. Often, useful nutrients remain in the voided material. Obviously, this is rarely a first choice, but between coprophagia (the technical term) and starvation, there is little hesitation.

Of course, a few animals are actually designed to eat their own feces. Rabbits, for example, have a sort of two-cycle digestion. The first pellets they leave are soft and green. They eat these, producing hard, dark pellets which are the true feces. If rabbits are prevented from eating their droppings (as with a wire bottomed cage), they can become ill. This really isn't much different from "chewing the cud" like cattle do, except that instead of being regurgitated from a special stomach, the partly-digested food is dropped out the back.

Answer 2

Some animals that eat feces of other animals include dung beetles, flies, certain species of birds like vultures, and some types of worms. This behavior is commonly known as coprophagy and helps these animals recycle nutrients from the feces.

Answer 3

Dunq beetles in Africa and birds eat un digested food from horse and cow dung.
