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 for my pet You get what you pay for. Though Science Diet is more expensive than other foods, I'm giving my cat actual nutrition instead of filler that cheaper brands use. That's my preference. He's a healthy cat. April 15, 2014
Cats loves it Gracie loves this product and she has it twice a day mixed in with other Science Diet products April 10, 2014
Excellant product! We feed all kinds of Hills food to our dogs and cats. Every product gives us GREAT results. We currently use perscription c/d, m/d and kitten (y/d, r/d, and w/d in the past) as well as optimal care for mature adult cats. Our dogs eat small bites for 7+ years. EVERY SINGLE food, wet and dry has shown us a beautiful, healthy animal... a super soft coat... and lots of energy. I highly recommend Hill's Science diet no matter what your pet's specific need is.

I feel this product is good for my cat over his lifetime, plus it is recommended by his vet. My cat likes the product and it seems to be good for him health wise. Your periodic $7 coupons help me budget wise . I have two cats (Himalayan and Siamese) that use two different types of Science Diet. March 13, 2014
Cats love the food We have been using Science diet dry food for our cats for a number of years and the cats love it and are very healthy and happy. We like the variety in selection for the different stages of life. March 2, 2014
Indoor Cat Equals Healthy Cat My kitties love this food. My three are 6, 11, and 16. Even though my youngest is not really a mature cat, she really likes the food. At their last vet visit, he raved about their condition and muscle tone. He said it must be do to their diet. He asked what they ate and we were glad to tell him. February 12, 2014
