Impalas and warthogs are medium-sized herbivores of Kenya. They are mainly vegetarians and are rarely a threat to other animals or human beings. But they are preyed upon by wild animals such as lions, cheetahs, crocodiles, and hyenas. Impalas are antelopes that like to roam the light grassland, woodland edges and savannas of Kenya, very close to water. They are always seen with erect postures, rubbing scent and making dung piles to mark their area. These vicious animals live up to 19 years. As the name suggests, warthogs have wart-like patches on their faces, but they are just skin growths.

An herbivore is a name given to an animal that eats only greens. They roam in the expansive plains of Kenya need more energy than the other beasts such as zebras, giraffes, lions, elephants, and cheetahs. The way they get this is by eating only plants, grass, vegetables, leaves of trees, and some fruits. They eat all day long, some of the herbivores even after sunset, especially on moonlit nights. The particular digestive system of many herbivores is adapted to digest their diet. The wild herbivores ideally found in Kenya are the eland, the wildebeest, the buffalo and the rhinoceros.
