Although at times t's difficult to make sure that only our older cats get this food, I do try to separate them as best as I can. This is a great variety that I use a few times a week for our cats that are 7 and 8 yes old. Although one of our cats is not strictly an indoor cat, I give it to him nonetheless. Both cats are quite healthy and have maintained beautiful fur. I highly recommend this product, have been using it for 2 years now.
