Rated 4.8 out of 5 by 179 reviewers.
Rated 5 out of 5 by Great product for continued health. We have 2 cats that were ferrel, both had health issues when they appeared on our porch. We fed them Optimal Care from the time they chose us for care givers and there are no health issues now. Both are healthy and happy little members of our family. May 16, 2012
Rated 5 out of 5 by 5 Healthy Cats We have raised 5 cats on Science diet. None have ever gotten sick. We have our Vet to thank for his recommendation 30 years ago. Our cats get only the Best, Science Diet. May 16, 2012
Rated 5 out of 5 by This product lives up to its name I buy the Optimal Care for my cat Boo and it really does live up to its name. His coat is so soft and shiny that it has ever been and his health and weight is where it needs to be for his age. He has the most energy I have ever seen in a cat. This food is by far the best for my baby boy!! October 5, 2015
Rated 5 out of 5 by amazed at the change I have tried numerous foods for my cats and it was a long journey to find a brand that would help my cats. My older cat Ivan is 6 years old and has an extreme sensitive stomach. He would be ok for a while but always threw up after a month or so. Then I switched to Hills Science diet. Not only did it help his stomach but his coat is gorgeous now. I have a kitten Daenerys who just turned one who has been on Science diet since we adopted her from the local shelter. She is beautiful as well. Healthy pets is all I ask for and they are now that they are on Hills brand foods. So thank you from the bottom of my heart. We are amazed every day viscosity and beautiful they are. September 3, 2015
Rated 4 out of 5 by optimal care dry cat food I've been buying the original dry cat food for over 10 years. It was recommended to me by my vet for weight control then when my cat lost her weight, I also told to which her to the original formula. She ate it for the next 6 years until she pass at the age of 18 (human years). Now, I've got a new cat, he's also on it. August 15, 2015
Rated 5 out of 5 by All My cats Love It! I have 13 rescue cats and a few have Gastrointestinal issues and also Heart problems. I dont believe in feeding your pet low quality cat food if you want them healthy. I used to feed cheaper brands of dry cat food and even hough my cats liked it they were having hairball and gastric issues. I decided to switch to the Hills Science Optimal Care dry food and as soon as I got home and opened the bag ALL 13 of my kitties loved it. I have been feeding Hills since about 1 month ago and since then no hairball issues and minimal gastric issues. Although more expensive I truly believe Hills has made my cats healthier and event their coats look shinier and full. Thanks Hills Science Diet. April 17, 2015
Rated 5 out of 5 by Science Diet Optimal Care for Cats When you take your fur baby to the Doc and here she has "pres-teen teeth" or "Her fur is so shiny and soft" or "Her skin is very good" you know your feeding her the right food. And then when your baby eats is all up, that just confirms your thoughts. I wouldn't change her food for anything. May 15, 2015
Rated 5 out of 5 by Great food for my felines, and also rescue fosters! Science Diet has always been the food of choice for my own cats. My cats love both Optimal Care and canned tender chunks with gravy! Several years ago I started fostering for a local rescue group. While I initially tried less expensive food products, I quickly decided the fosters needed the quality of Science Diet! I have cared for moms with newborns, orphan kittens, and some with illness. So far, they have all loved and thrived on Science Diet! Without a doubt, I'll continue using Science Diet for both my cats, and fosters that come my way! February 6, 2014
