My rotation feeding method for my cats

As many of you have probably noticed, I feed my cats several different types of food (I agree with the rotation feeding method). I try to stay grain-free with my selections. I currently feed Blue Buffalo Wilderness Chicken Recipe as the "main" food with Sheba Pate canned foods (mostly the turkey and the whitefish and tuna ones) and Wild Calling kibble included in the rotation as well. I also get different canned foods (brands/flavors) as well. I have now started to introduce RAW into the rotation as well. I picked up a bag of Nature's Variety Instinct Frozen Raw Duck Bites yesterday and let the cats try it today. After sniffing it for a bit (it is very different in texture, smell, etc.), they decided it was food and scarfed it down. Hopefully they continue to eat it. The main reason I am using the brand I am is because of the safety and quality control methods that they use to prevent bacterial contamination. So, to wrap it up, in my rotation for the cats, I feed Blue Buffalo Wilderness dry, Sheba canned, Wild Calling kibble, Nature's Variety Instinct Frozen Raw Duck Bites and assorted other canned foods. I figure that feeding a wide variety of foods will lead to less "food boredom" as well as fewer health problems.
