We switched the herd over to Orijen without any issue. The food is kind of stinky, IMO. But they all seem to like it. I do give them all a tablespoon of wet friskies or whatever is on sale, in the am (a habit I am so sorry I started!!!), and they graze on dry throughout the day.

Once my cats hit 8 or so months, my vet said there wasn't any 'need' to keep them on kitten food, as long as the food was a decent brand.
