Do you feed your cat wet food?

Our two inside cats have a tendency to vomit up their food and hairballs..(at least once a week).One is a long haired solid black...I have put the "hairball remedy" on their paws or where they can lick it off, but they are not fond of doing that at all...I have also bought some of the "grass" you grow in small containers and let them nibble on it. Neither have weight issues. I guess its just a "trial and error" thing to find what food they tolerate the best.
