  • Great size and flavor

    By on

    My cat has been on Science Diet since birth. He has grown up on it, from kitten food to adult light. I had an old cat that developed kidney infection & had to be hospitalized. The vet told me to prevent further infections he needed to stay on Science Diet. After the first horrible infection, he never had another. All my cats will always eat Science Diet of some type.

  • Great product

    By on

    I have used Science Diet for both cats and dogs for over 20 years. I have yet to get a bad bag or hear of a recall. My only complaint is that they are a bit pricey, but as the old saying goes, you get what you pay for. I would recommend this product to everyone. My cat's coats are shiny and healthy.

  • A hit...and then just food. Such is life.

    By on Top 500 Contributor

    We switched over to this from another low calorie kibble. Hill's has a good reputation in the veterinary field for making good quality foods. I think the price is great for the quality. We switched from another high-end but more expensive brand to this, and saw that our cat liked this more and it also helped her lose more weight. She ate this very enthusiastically at first and now, 3 months later, we put it down and she takes her time walking to the bowl and finishing her breakfast. Sometimes she leaves a few pieces for lunch (she always finishes before dinner). But, she eats the same kibble every morning...I don't really think it's the product's fault.

  • Hope it works

    By on

    I needed to try something for my cat to loose weight, as he is an indoor cat. I did research and read reviews on this brand of cat food, so I bought it. Now, the waiting begins, hope this will work, I don't give him too much about 1/2 to 3/4 cup twice a day.

  • My cat said No Way.

    By on

    This particular flavor did not make a hit with my cat at all and it was a struggle to get her to eat it. It has a funny smell too. I have used other flavors of the Hill's Science Diet and she likes them fine.

  • My cats love this

    I was concerned when my cats stopped eating their dry food. My cats were over weight and that concerned me. Now they are eating and not gaining additional weight.
