Ingrediants as described and helped our cat with many digestive issues. We saw good results in about a week. Our cat had many stomach and absorption issues but this helped calm the problems down and gave him the nutrition he needed. Quality of Ingredients There were no real additives or fillers in this that would be an irritant to our cats tummy issues. The firs few days we were switching the food from one to another slowly and we could see the change already! The other brands of food we had tried we think the irritant was the food color and the artificial flavorings, but this he had no problems after we had fully switched over. When we switched back tot he other food as we had run out of the ID and the Vets was closed we hat to go back to his old food and we could tell within a few hours it was the ingredients in the old food that was causing the problems Flavor Selection I think this had the fish flavor an he took to it right away as that was his favorite flavor of food.
