The answer to this question is no - cattle have one stomach with four compart-ments. This kind of stomach enables them to bring swallowed food back into their mouth to be chewed and swallowed again; this is known as chewing the cud. Animals with such stomachs are called ruminants. The compartments are the rumen, the reticulum, the omasum and the abomasum. Each cavity helps digest food with the aid of numerous micro-organisms, such as bacteria and yeasts that live in the stomach. The fourth cavity is the 'true stomach', which functions in the same way as the stomach in human beings and other mammals that are not ruminnts.
