I'm looking for a high quality certified organic cat food. So far, I've found three brands- Newman's Own, Petguard & Organix. Has anyone had any experience with these? Are there any other brands out there?

Both of my cats seem to like Organix. I haven't tried the other brands you mentioned. I'm interested in checking them out now, to see how they compare to Organix and Wellness (the stuff I'm currently feeding my guys). Wellness is supposed to be made from human-grade ingredients, but my cats have decided they're tired of the dry Wellness food. :-/

Organix is the one that I'm leaning towards right now. Do they have wet food, too, or just the dry? So far I've only found dry.

Divine, the Organix is only available in dry form, and dry treats. Did you find Newman's Own and Petguard at a chain pet supply store? I haven't seen them yet!

No, I found them online.
