My cats have been fed Nutro Natural Choice and were thriving on it. Now it's being reformulated so I don't trust it (reformulation =?cheaper). I've heard a lot of good things about the various Blue Buffalo brands, and like what I see on the label. I was wondering if anyone fed their cats this brand, and, more importantly, do they eat it? It's pricey so I was thinking of getting a small bag of the Wilderness and mix it in with the Nutro.
