on my cat forum people are freaking out about this too. Some of them were e-mailed a survey about Natura foods and one of the questions was:
"Currently, EVO Red Meat contains five different red meat products. Consideration is being given to adjusting the EVO Red Meat formulation to include two types of red meat protein, Lamb Meal and Beef which will result in a more balanced formula. This change may reduce the level of protein in the food from 42% to as much as 31%. The new EVO Red Meat will have a more balanced distribution of calories from protein, carbohydrate and fat. The formula will remain grain-free."
so clearly they are planning on downgrading and using more calories from carbs and less from meat, great. That's three foods in my rotation gone, I'll be really ticked if they change anything in EVO, the 95% meat canned foods are SO good for them (my cats).
