Customer Ratings & Reviews

Rated 4.5 out of 5 by 36 reviewers.
Rated 5 out of 5 by LOVE this food! My 15 year old cat is like a kitten on this food! We needed to decrease her protein level so I tried this food. She is running around all the time and eats this food like crazy. She has Hyperthyroidism and has been taking meds for over a year. She eats Fancy Feast canned and this food. What a change!!!! Maybe they put catnip in it-LOL May 5, 2012
Rated 4 out of 5 by Cats love it My 14 year old female loves it. Because of her age I wanted to buy something special for seniors. So far so good. January 11, 2013
Rated 5 out of 5 by Our "Senior" Cats Love This Cat Food Our two "Senior" Ragdoll cats made the switch to Hills Science Diet Age Defying cat food several months ago. There were no problems with the transition...they both liked the taste and the smaller kibble size is perfect for our one Ragdoll who had lost a tooth. Within a few weeks we noticed fewer digestive issues and an increased energy level. Also, it cleared up the eye discharge that one of our Ragdolls had had for many years. We are very pleased with this cat food !!! June 10, 2014
Rated 5 out of 5 by The only dry food I feed my cats. I've been feeding my cats and kittens Science Diet dry food for over 30 years. Barring accidents, my cats have lived a long and healthy life that I attribute to the excellent diet provided them. I have tried other brands but usually they have been a waste of money - the cats just didn't want anything else. Additionally, when my neutered male cats suffered a bout of FUS the vet has prescribed the canned SD prescription food. I will continue to use Science Diet cat food as long as I own cats.

Rated 4 out of 5 by Great if your cat prefers tiny kibble size. My cats all eat Hill's, both Science and Prescription Diets. None of them would touch this, and I believe it was because the kibble is the smallest I've ever seen. My seniors still like to crunch their food. I gave the bag to my neighbor, who has a cat with only one tooth. She said he loved it and had me order her another bag. She said it seemed to give him more energy and a shinier coat. So -- if you have cats with dental issues who need a tiny kibble, give this a try. April 15, 2014
Rated 5 out of 5 by 12 year old loves it W are pleasantly shocked that our twelve year old guy likes this dry food. He's always been fuss with dry having been an indoor/outdoor farm cat his whole life. He eats this with no reservations and his black Persian-like coat has never looked better. March 7, 2014
Rated 5 out of 5 by Good quality food Since both of my cats are quite elderly, my vet recommended this food for them. They love it so I am happy. November 25, 2013
Rated 5 out of 5 by Helps Raise Beautiful Healthy Cats We have 3 cats which are litter mates and are 12 years old. From the day we got them at 10 weeks we have fed them only Hill's Science Diet. They've had every age specific type of food Hill's offers. They have now progressed to Hill's Age Defying. It's awesome. The small kernels are much easier for the cats to eat and easier on their old teeth. Also, Age Defying is easier on their digestive system. Our cats have always been healthy with thick, shiny coats. I wouldn't feed our cats any other brand. Have been using Hill's Science Diet around 20 years. We started with another cat we had that lived to be 18 years old. June 20, 2014
