Rated 4 out of 5 by My cats love this food. I have fed Hill's Science Diet to my cats for over 10 years and they love it. December 19, 2014
Rated 5 out of 5 by So worth the price! Our young cat was recently diagnosed with FeLV. The vet said in order for him to have any chance at living very long he would need optimum care, including a high protein quality food. Hills meets that need and Sammie really loves it. He is maintaining a good weight and staying healthy so far. Thank you so much for supplying quality pet foods at affordable prices! September 19, 2014
Rated 5 out of 5 by The litter box dont smell!! That is what I really love about it! And it takes very little to fill them up. I feed all five of my cats and the feral cats the same makes them look so pretty, I have the best looking feral cats in the neighborhood! May 1, 2014
Rated 5 out of 5 by this has everything my cats seem to need I have used Science Diet for my cats for about 15 years. I will not give them anything else. They like it and it is recommended by their vet- can't get a better refrence than that. I haven't tried any other product in all these years and don't plan to try anything else. I have 2 cats and they both like it. June 15, 2012
Rated 5 out of 5 by Great product for an overweight cat! All of my cats enjoy eating sciences diet dry cat food. One of my cats was very overweight. After changing his dry cat food to science diet, I could see a big difference . He is nine years old and he has more energy and he looks great. He lost a few pounds after two months of being on science diet dry cat food. August 12, 2015
Rated 5 out of 5 by Satisfied Cat After acquiring a 2 year old cat two months ago, I started feeding her the Optimal Care dry cat food. She enjoys it so much that she tries to help me pour it in her bowl. There is never a morsel left and her skin and coat look good. Thank you. December 3, 2014
Rated 5 out of 5 by A good quality food We have 4 dogs and two cats. Our animals are well taken care of and loved so we feed what we think is the best quality November 24, 2014
Rated 5 out of 5 by The cats Love it, and so do I We have rescue cats, and one of them recently had kittens. Now 14 weeks old, they and the other 4 adults have no problems with the Optimal Care. I know it's not meant for cats under 1 year, but they all thrive, and are very happy cats. We love it for the price and since it is Science Diet, we know we are feeding them the best. The local vet agrees totally. Thanks October 23, 2014

Rated 5 out of 5 by Good cat food My cat loves this food. He is beautiful. He has a beautiful coat and a nice trim body. August 3, 2014
Rated 5 out of 5 by Satisfies my cats I was feeding another brand of cat food. My cats were constantly wanting to be fed and acting as if they were not ever satisfied. I began to wonder if they were not getting enough nutrition. After reading the labels at my local store I noticed chicken was the first ingredient in this cat food. Now they eat less and I am not actually out more money even though this food is quite a bit more expensive. July 23, 2014
Rated 5 out of 5 by Love this product! I've had cats my entire life, and occasionally we try other brands of "better" cat food, only to come back to Science Diet. Our household of cats have fewer stomach issues, better health, and overall better/beautiful coats. We love our cats, and they love Science Diet! June 21, 2014

Rated 5 out of 5 by Science Diet Optimal Cat Food I have been feeding this to our cats for years without out issue. Their coats are beautiful and their health issues are few. December 18, 2014
Rated 5 out of 5 by LUV LUV LUV I am very happy with Hills Science Diet products and so are my 3 cats. They stay sleek and shiny and best of all, there is no odor from the litter box - even after several days of accumulation. As for Chewy, they are great, fast and inexpensive deliveries and a multitude of choices. September 3, 2014

Rated 5 out of 5 by Hill's Science Diet Adult Dry Cat Food Excellent dry cat food for my cats. They have been eating Hill's cat food for years and its really been good for them. Awesome brand of cat food and would recommend for anyone with cats to use this food. November 5, 2015
Rated 5 out of 5 by My cat loves this food. The Science Diet food totally agrees with my cat and her system is running perfectly. Seems to have just the right amount of oil and everything she needs to stay healthy and happy. The vet recommended we use the Light to get her weight down and that worked really well. Now she's back on regular and doing great. September 23, 2015
Rated 5 out of 5 by My cats love it My cats love this food even the one who never liked any kind of dry food. July 28, 2015
Rated 3 out of 5 by He likes it but it has chicken triggering allergies Tastes good to Mr. Fussy, but the chicken in this product causes over grooming and itchy tummy & ears. July 5, 2015
Rated 5 out of 5 by My Cat's Love IT! Fast shipping, packaged great!!! Will go to for my next dog and cat need order :) April 6, 2015
Rated 5 out of 5 by Science Diet Everyone knows Science Diet is a good product, but the best part of buying it at Chewy is price. I've saved quite a bit by shopping at Chewy, but I've saved more on this product than any other item. March 21, 2015
