Cows are mammals that are real big. They eat hay wheat and grass. They drink water and milk. They are like goats but bigger and without horns. Male cows are called bulls they charge at people waving a red flag sometimes. Cows are noisy the go moo!. they are friendly when they know you. The babies need a half or a bottle of milk a day thats a lot. They also need a bail of hay every day or more. So cows eat a lot but they do not eat meat they are herbivores that means they only eat plants like corn lettuce tomatoes and cabbage.
