Recommended! We started using Hills Science Diet Optimal Care with my cat, Jenner, before he was even a year old. We really had nothing to lose. You see Jenner was a very sick kitten and he struggled to gain weight despite trying "the best" foods. After switching to something more natural he gained about a lb in 2months, but he was still very under weight. Our vet gave us some of this to try after winning the bag during a special open house. We gave it to Jenner and he started having less gas, he was more energetic AND he was finally gaining weight. Jenner still has health issues but being underweight is no longer an issue and as long as he isn't on antibiotics his "tummy issues" aren't a problem anymore. We owe a lot to Science Diet. Between my obstinate never give up attitude, careful vet care and SD Jenner is now a healthy 7lbs with the silkiest coat around. March 26, 2013
Great for healthy happy cats I transitioned my cats to this product when they were old enough to move from the Hill's kitten food they received at the shelter from which I adopted them. They have been and remain healthy and I believe happy with shiny coats, appropriate weight, and lots of energy. December 18, 2012
Vet recommended 38 years ago, my vet recommended Science Diet for our first cat. Seven cats and six dogs later, it's the ONLY pet food I've purchased. I credit it for giving my pets beautiful coats, staying healthy, and a long and happy life! Thanks for a great product for the animals I love. November 23, 2012
Mmmm When i first opened the bag up i thought it smelled great. You could really smell the contents of the food and it just smelled so fresh and real compared to cheaper stuff i have purchased. My cat turned her nose up at it the first day but she got used to it after that and eats it regularly. I think this is good to mix with the cheaper stuff if you aren't wealthy. September 10, 2012
Good food equals healthy pets You are what you eat and this is true for my pets. I would never feed them anything else but Science Diet. August 22, 2012
My cats love this food My cats love this food. They are active and seem very happy with their food. Their coats are in better condition and not as dry August 13, 2012
This product is teriffic. I adopted a 3 year old cat at the shelter and was concerned about her size (she was a little too big in my opinion). After reviewing several cat foods on-line and talking with friends and veterninarians, I chose to start feeding Suki Science Diet Optimal care. Following the guidelines, she has trimmed down nicely and enjoys the food as well! Thank you!. July 26, 2012
Popular This food is very popular with my cats. It keeps disappearing! They are a healthy, happy clowder. July 17, 2012
