After trying several of the premium/natural brands, my cats and I settled on Nutro. They love it, and it does wonders for their coats, attitudes, and energy levels.
We've tried both Nutro Max and Nutro Natural Choice dry foods, and they love them both.
I have had foster cats who liked the Nutro wet foods, but my two cats don't care for it...which is fine. They get plenty of nutrition from the dry food.
While we were in the process of moving, and I couldn't get to the pet store, I grabbed a bag of Purina at the grocery store. I swear the difference was amazing. My Fenris looked as though he was wearing his fur coat inside out. Gizmo, who's fur is usually sleek and soft, felt like he'd been neglected for years. As soon as we got moved, I bought Nutro again, and I will never make the mistake of trying the stuff I can buy in the grocery store again!
