Yes, my three are currently on the Green Pea & Chicken formula. They like it and seem to be doing fine on it, although I don't feed it as a main staple, so I can't give it all the credit.
I use the Venison and Green pea, and my kitties love it; it is part of their LID (Limited ingredient diet). There is a new one out, Salmon and green pea, but my kitties hated it...
They seem to like Green pea and duck as well.
we also provide this food for the "semi-ferals and stray" we care for outside
they all get a premium (not Natural Balance) canned food - the cats didn't like the Natural Balance flavors available at PetLuv - except for the fish stuff - and I don't feed my cats any fish)
Natural Balance also has a discount - I save the UPC codes on the package - for every 10 bags I purchase I get a free bag
the ferals and stray - I try to feed them the best we can afford trying to keep them healthy, too
