While I am sure that these recipes are exceedingly healthy, as they should be, they were naturally, quite complex in that they all required many, many ingredients, and not necessarily easy ingredients to come by. It is also truly a pet FOOD cookbook; there were no dog or cat treat recipes included. (And you can't keep changing a pets' food or it will upset their stomachs/GI tract. Once you start making the food, you'd have to keep up with it.) I decided to not make any of the recipes in the book and instead opted to go online to look up dog and cat treat recipes as a supplemental to my pets' regular food.
