No more turned up noses I have four cats, and two of them are in the mature range. With other foods, they would turn up their noses and head for the other cats' food, but then I discovered Science Diet Mature Indoor Dry Food and now I have to hide their food from the others. Even though this particular product is not for hairball treatment, I've noted their hairball episodes have ceased. Overall, I have found this food is excellent in every way. My cats and I are very satisfied. November 13, 2013
He doesn't need to eat much, but it does a lot. Years ago my vet, who was very committed to economy in pet care, told me to use Hill's Science Diet rather than any other product. Although Science Diet cost more than other pet food brands, she firmly believed it was worth it. My cat eats and thrives on Science Diet, and nobody believes he's eleven. He could easily be a year old, with soft, thick fur, bright eyes, lean muscles and perfect blood work. June 30, 2013
great food that my cats love. too expensive I have been using.Science Diet food since about 1995 and have always been satisfied with the qualitym . My cats are all mature atm and it's getting harder to fine the indoor formula ( my cats love the triangles.and.they eat itnslower and vomit less as long as I feed it) It's also gettimg harder and harder for me to be afford the food. The price keeps going.up, the bags keep getting smaller and there are less and less coupons offset the prize I currently have 4 cats to feed and I am seriously considering switching to another brand.

Vet recommended Our Vet does recommend Hill's products, and we are glad to see the formula changed to a more flavorful feed. All our 10 cats eat this food, and seem to be doing fine. I like what our Vet had to say about Hill's food. Now, if you could do the same thing with your canned food. September 15, 2014
3 Cats Like It! My three cats like the change to 7+ Adult Cat food. They needed to change from the food they had been eating all their lives and Science Diet was the best choice. They think they are getting a treat every meal! September 5, 2014
Benefits for four cats We have four cats. Two are 15 yrs and two are 3.5 yrs. They all eat the same dry food. Change off from adult 1-7 and then adult plus 7. Since feeding older cats the past couple years. their coat is shinier and filled out, other skin problems have gone away. September 3, 2014
Mature Adult Indoor My 10 yr old Siamese loves this food. He will not except it if we run out and have to go to the store. He will cry until we get back with the new bag. No better testimony about how an animal likes it then that! July 16, 2014
My cats LOVE science dirt. I always recommend Science Diet to anyone who asks. July 13, 2014
