It's not been established beyond doubt why cats need grass.
One theory (the oldest) is that it helps them in some way to cope with
hairball trouble, in some cats by making them throw up the hairballs, in
others by easing the hairballs smoothly through the digestive tract.
Another, more recent, says grass (or other plants) may give cats and
other carnivores a certain vitamin (in the B-group, I think) that is
difficult to get by if you are a mere carnivore.

Or hey, maybe it just tastes good!
