Cats chew grass - I don't think it's really clear why, may be something
to do with digestion - often seems to stimulate them to regurgitate
furballs.

If they don't have grass available, then they will often turn to
houseplants instead.

So it's suggested that indoor cats should have a tray of grass
available.

Not that I've ever known one that actually eats the stuff sold as cat grass.
