We created the Four-Star Nutritionals line of products specifically to provide variety and encourage rotation. Each recipe is designed to be complementary, and after transitioning to Fromm, many customers have success rotating between Four-Star recipes and even our other lines including Fromm Gold and Fromm Classic.
Finding the right food for your pet is sometimes trial and error. One of the benefits of Fromm's interchangeable lines is the ability to switch seamlessly to new recipes should you or your pet become unsatisfied with a particular entrée. However, all pets are different, and some pets have more sensitive stomachs which may prevent them from enjoying a particular recipe or a rotational diet. Other pets are more robust and require no transition period between recipes. It's really up to you and your pet how much rotation you would like to incorporate into their diet.
