[2] Horses, cattle, geese, guinea pigs, hippopotamuses, capybara and giant pandas are examples of vertebrate graminivores.
Some carnivorous vertebrates, such as dogs and cats, are known to eat grass occasionally.
Grass consumption in dogs can be a way to rid their intestinal tract of parasites that may be threatening to the carnivore's health.
Graminivores generally exhibit a preference on which species of grass they choose to consume.
For example, according to a study done on North American bison feeding on shortgrass plains in north-eastern Colorado, the cattle consumed a total of thirty-six different species of plant.
