Why do cats eat grass?

No one seems to know exactly why cats eat grass, but it is a commonly observed behavior that happens with lots of cats, and even a lot of dogs. There isn't any nutritional reason for them to eat it - it doesn't have much value for them in terms of calories, etc. However, some of the theories about why they do it are that it is good for digestion or helps them pass hairballs. It is a natural behavior though, and cats will do it with a lot of different plants.
