Rated 4.7 out of 5 by 123 reviewers.
Rated 5 out of 5 by Cats Stay Fit and Healthy I have five cats who, while eating Science Diet, were getting overweight. I switched to Lite cat food, and the cats love it and have lost weight. They're still energetic and their coats are thick and shiny. We will always use these for our five rescued cats and any future rescues! May 17, 2012
Rated 5 out of 5 by The ONLY food my cat eats! My cat started eating Science diet kitten food when she was just a few weeks old. As she got older she ate the different stages of Science Diet. When she was about a year old she was a bit overweight due to being so unhealthy as a baby( the vet said I had to put weight on her! She was so sick she was going to die) I put a bit too much weight on her so now I had to get so e off her, I started her on the Adult Light food and she did great, she lost some weight and has been doing very well. She is now 7 years old and still eating the Science Diet adult light food and doing well, we still believe she is a bit overweight at 11 pounds she is way down from the 14.5 she was. Thank you Science Diet for giving me my cat back and not having to break my daughters heart by having her put down just 2 days after we got her because she was so sick!!!!! We Love your products and have recommended them to so many! July 18, 2013
Rated 5 out of 5 by love how my cat looks after being on it for a while. She has been able to keep a good weight she is a cat prone to being over weight so I really like that it prevents that. Her coat is very shiny and soft. Also at least once a month we give her a bath to keep any itching, dry skin or hairballs to a minimum. August 24, 2014
Rated 5 out of 5 by Loves it I have to measure her food-- she loves this stuff! August 4, 2014
Rated 5 out of 5 by 3 Cats We started feeding our cats this food when we adopted a male tabby and our vet recommended it (the Light formula because one of our cats is a bit, ahem, portly). I never realized the difference good, quality food can make! Our three cats now have shiny, soft fur and much more energy. Our vet says they are all in great shape. I tell everyone with a cat that Science Diet is the way to go. May 21, 2013
Rated 5 out of 5 by Quality food That's all my cat will eat We tried getting something at the market in a pinch when we were out of town. But he would not eat it May 30, 2014
Rated 5 out of 5 by A LITTLE FATTY BUT CUTE My cat is an indoor cat and a little overweight so I mix up the different dry food and she loves it. She also will eat this by itself - she has to keep her girlish feline figure. May 16, 2012
Rated 5 out of 5 by All FOUR of my cats LOVE Science Diet! My cats coats are always shiny and in good condition. I am convinced it is the nutrition they receive in Science Diet Adult light. I have recommended Science Diet to other cat owners, that have experienced the same healthy look in their cats after switching to Science Diet Adult. Thanks!!! May 16, 2012
