What does a horse primarily eat?

a) grass
Although, if a horse gets a taste for meat it can quickly become an addiction and the horse must then satisfy its red meat addiction. The horse will try to stampede small mammals like rats and cats and it will then feast on the red meat and blood. Some horses have been known to attack small children. In Germany, these horses are known as the Pferd Vampir which means "Vampire Horse".

Grass and hay.
