the reason being is that they are less likely to develop an allergy to a protien if the food is rotated with a different protien. It also gives them a change in flavor and makes them less sensitive to sudden food changes. I always mix the food 25%, 50%, 75%, then all new food. This also helps with the transition and less likely to cause any problems. I rotate the Timberwolf foods. If you purchase from their website they offer free shipping. Right now they are on the Ocean Blue which is grain free. With the variety they offer, it is great for rotating. You don't have to rotate between brands, just protien sources. You could rotate all Natural Balance or Rotate between the Solid Gold and the Natural Balance. Good Luck!! In my opinion, it is better to rotate!!
