Many animals, from tiny insects to huge elephants, depend on grass for their daily needs. Some, like chickens and wild turkeys, occasionally eat grass, while horses, cows, sheep, and bison are true grazers that roam grasslands and meadows, feeding on the green carpet that covers large areas of land.
Even carnivorous animals like a dog might bite and chew on blades of grass, although it’s not a primary food source for them. In this widespread realm of grass consumers, grasses play a vital role in ecosystems, providing nourishment for many species, including kangaroos, buffalo, and zebras. These animals rely on grass for survival, along with countless others that are too many to name.
Types of Grass-Eating Animals:
Herbivores
Herbivores like deer, elephants, and rabbits rely on plants for sustenance, utilizing specialized digestive systems to break down tough plant fibers in their diverse diets. These animals contribute to the ecosystem by grazing and browsing, promoting vegetation growth, ensuring their survival, and maintaining the balance of life in both grasslands and forests through seed dispersal and enhancing resilience in nature.
Omnivores
Grass-eating animals in the animal kingdom display remarkable adaptability and diversity in their diets, often being omnivores that thrive on plant-based foods like grains. Some of them including bears, humans, raccoons, and pigs, also consume fruits, vegetables, and insects, highlighting their dietary flexibility.
This flexibility is crucial for their survival, as these animals play a vital role in controlling populations of plants and other animals. Their feeding habits contribute to the ecological balance in ecosystems around the world for highlighting their value in preserving the natural balance.
Insectivores with Grass in their Diet
In nature, insectivores like hedgehogs and shrews showcase the versatility of animals that feed on both grass and insects. These creatures supplement their diet with insects that allows them to gain essential nutrients and fibers from the vegetation.
This creates a unique combination of food sources that reflects their adaptive capabilities. Their feeding habits highlight the interconnections in ecosystems, which are crucial for sustaining diverse wildlife populations and various species.
Animals That Eat Grass

At the same time, the other includes grasses like Dicanthium, Enneapggon, and round-leafed saltbush, amounting to 31% and 12%, respectively. These spectacular beings can live for crunchy periods without water by discovering means of keeping water and diminishing their body temperature.
Kangaroos in red can make a significant jump to 9 meters at once. What is remarkable is that the yearning in the female Red Kangaroo is for twins, but only one will reach maturity.
4. PANDAS
Scientific Name: Ailuropoda melanoleuca
Pandas are cute animals with a unique black-and-white appearance that rely on bamboo as their primary food source. They eat about 40 pounds of bamboo daily to meet their nutritional demands, but may also pick from other plants, tubers, and small rodents or carrion. Their consumption can differ based on variables like habitat quality and seasonal variations, allowing them to choose a variety of foods to survive in the wild.

5. Monkeys
Monkeys have a varied diet rather than only bananas. Monkeys are omnivores but mainly eat plants, fruits, and seeds. Among the primates, however, the Geladas primarily feed on grass.
On a domestic level, Herbivores eat grass. The diet of cows, goats, horses, and donkeys consists of daily grass (or hay). Dogs and cats have been known to eat grass as well.
6. GOPHER TORTOISES
Tortoises are hard-shelled reptiles that are found all over the world. Tortoises, such as the gopher tortoise, are herbivores whose diet consists mainly of plants and grass. In the forests, this species likes to live in scrublands where the soil is nice and sandy for them to dig.
Unlike other tortoises that live west of the Mississippi River, gopher tortoises are among the few species residing in the eastern part of the US. They are the staple art of states like Florida, Georgia, and others surrounding them. Gopher tortoises have almost become extinct in South Carolina and Louisiana.
7. CAPYBARAS
Scientific Name: Hydrochoerus hydrochaeris
In a paragraph: The capybara is a species of the rodent family Hydrochoeridae. It’s the most giant rodent in the animal kingdom, with an adult’s average weight ranging from 35 to 66 kg (77 and 146 pounds). The capybara is native to Central and South America and is a highly demanded exotic pet.
Capybara is a herbivore, feeding mainly on grasses, water plants and fruits. Capybaras provide primarily on green vegetation and prefer fresh, succulent growth. Nevertheless, even if they’ve dried, they will eat grasses just as they consume trunks or barks.
8. Rhinoceros
Rhinos are among the heaviest land-dwelling mammals, weighing up to 8000 pounds. The grass is most of what they eat, and other vegetation, including plants, fruits, and trees.
White rhinos mainly feed on shorter grass, whereas the others prefer higher grass and sweet fruits.
9. ZEBRAS
Scientific Name: Equus quagga
Zebras are herbivores in Africa, recognized for their black and white striped coats that graze on nutrient-rich grasses and short grass species in luxuriant grasslands and forests. Their quick movements and sharp senses allow them to preserve ecosystems while sustaining their energy levels, playing a critical role in regulating plant growth and fostering biodiversity through a dynamic interplay in the wildness of their environment.
10. Wildebeests
Wildebeests are a mammal known for their migration throughout the year.
They survive in great companies with as many individuals as thousands of grasses—lots of grass. Therefore, feeding the animals is challenging for cattle owners, especially when vying for grazing land. Wildebeest binges are primarily on short, scarcely-spaced grass and succulents.

11. LLAMAS
Scientific Name: Lama Glama
We llamas of South America can be categorized among the camelids, just like our camel relatives, and we have all developed the ability to thrive in the harsh conditions of the arid life. Llamas typically live in the Andean Mountains, eating from a mix of grass varieties and bee-friendly crops such as clover, alfalfa and dandelions. Other than alpacas, some camels are found among plants like bushes and cactuses.
12. PRONGHORNS
Scientific Name: Antilocapra americana
Pronghorns are the prairie-living antelope of North America. Unlike other antelopes, these animals, Christened the “Pronghorn,” are not only the sole members of the Antilocapridae but also inhabited the Americas. Pronghorns can run fast even if they are not runners by nature& they can run up to 40mph.
These fast animals mostly eat grasses and bushes; however, they feed on leaves, buds, flowers, or fruits once they get a chance. Because of the plenty of food, it can always have something to eat through the different periods. As genets are concerned, the pronghorns like forbs in the spring and summer, but they feed on shrubs in the late summer and autumn.
13. Camels
Camels are herbivorous mammals that thrive in arid deserts by using physiological strategies to efficiently break down tough fibrous vegetation, including prickly bushes and dry grasses. They possess extraordinary endurance and an acute sense of smell that allows them to travel miles in search of patches of flora and water. This ability helps them survive in hostile environments where food is scant.
14. Bison
Just like cows, bison have a 4-chambered stomach due to the nature of their plant diet, which needs to be broken down into simpler components.
Bison are grazers that spend most of their time on the ground feasting on prairie grasses. However, they can also eat trees, shrubs, seeds, and tree bark in the winter.
15. Hippopotamus
By far one of the most enormous mouths of all land mammals, this fact may make some think that a hippo is a carnivore.
They can consume up to 80 pounds of grass daily, favoring feeding at night. They could travel a distance to finish the food in the required volume.
16. Hare
