Non-ruminants are considered a monogastrics because they have a simple stomach. They cannot regurgitate partly-digested matter and re-chew it because it is not necessary; they do not have a large rumen . Almost all non-ruminant animals are omnivorous or carnivorous. Animals that are herbivorous and are non-ruminants have a functional cecum that is used to ferment the food that they have eaten once it passes through the stomach and small intestine. Such animals are called "hind-gut fermentors," and yet are still considered non-ruminants.
Ruminants are animals which have a four-chambered stomach specially designed for digesting plant matter. No ruminant animals are carnivorous or omnivorous by nature because their stomachs are designed to digest coarse hard-to-break-down material being plants like grass, not protein, (which makes up meat) which is much easier to digest for the average animal, ruminant and non-ruminant alike. The names of the four chambers of a ruminant are called the Rumen, Reticulum, Omasum and Abomasum, each with a different "job," that is responsible for the complete digestion of coarse plant material. They regurgitate food--called "chewing the cud" The rumen acts tile a huge fermentation vat where additional essential amino acids and proteins are made by the bacteria in the rumen from the basics that the animal has consumed.The rumen and the reticulum is 85% of capacity.
