Just an FYI. I requested samples from Young Again and I just received them today. They included a sample of their new Zero Carb Mature food, to be released in the next couple of months. It is supposed to have reduced minerals, such as phosphorus. I am requesting the ingredient analysis (it wasn't sent w/ the food). While I know most people on here feed wet food, as do I, it's good to know that there is now a mature zero carb option for those times when our kitties refuse to eat their wet food.... like SOMEONE is doing tonight!
