How is a kangaroo’s stomach similar to a cow’s stomach?

A kangaroo’s stomach is similar to a cow’s stomach because both animals possess a chambered stomach that functions as a specialized site for the fermentation of plant material.1

This adaptation is essential for both species because they consume diets high in cellulose, a tough plant component that most animals cannot digest on their own. In both the kangaroo and the ruminant (such as a cow), microorganisms within the stomach chambers break down this cellulose into usable energy sources, such as fatty acids. By utilizing these specialized stomach chambers, both animals are able to extract necessary nutrients from fibrous vegetation like grass.123
