Can anyone recommend a grain free dry cat food?

[steph]

My kitty eats mainly canned, but a little dry throughout the day, grain free is the way to go I was told, I have tried Core and Evo, got very gassy and nasty stools for awhile, he won't touch Merrick BG, any other suggetions? California Natural?

I think the Indigo dry is without grain too, but they use potato and yams in it.

We tried Prairie, the three cats didn't like it.

How about the standard Wellness (not the Wellness Core)?
