Making raw cat food at home isn't hard to do at all, anyone can do it. Once you make your own, you will realize that raw cat food isn't complicated. It helps to know how ground raw diets are made, because commercially made frozen foods are made in much the same way, just on a larger scale. Taking the mystery out of what you feed your cats is important. While your cats benefit from the nutritionally better food, the benefit to you in terms of peace of mind shouldn't be overlooked.
