I purchased this product but have not started using it yet. I know for sure that at least one of the vets I consulted never heard of it. I am dropping off the instructions for a diabetic cat at both vets today. Even though I home test, I am nervous about using insulin with this product. The instructions say that if u don't home test you should discontinue insulin when you start using this product. Does anyone on the board have experience with the Young again No Carb food??
