If your cat is on the hefty side, this food is a great option. The serving size says only a 1/4 cup a day is necessary, but I chose to use 1/8 cup, and mixed it with regular food for the first few days. After this, I went to the 1/4 cup suggested serving, and it worked great. In addition to seeing my cat slim down, it is also made with natural ingredients, and there are no fillers or byproducts as is the case with many other food brands. Quality of Ingredients High quality ingredients. The first thing you see on the label is chicken (beef or lamb); additionally, there are no fillers like heavy wheat based products, no heavy broth or liquid, and there are no bones or other fillers. All natural and all healthy ingredients make this a great option food. Flavor Selection This is quite limited in comparison to other brands of cat foods, namely because of the fact that it is for weight loss, and only includes all natural ingredients. From what I have seen at my local pet shop it only comes in a beef, poultry, or a lamb based flavor.
