Rated 4.6 out of 5 by 81 reviewers.
Rated 5 out of 5 by Sleek, Slim and Energetic Oskar loves Perfect Weight! He had been on other light formula food without losing weight. He also didn't lose on his prescription food so when the opportunity to try Perfect Weight presented itself I jumped on it. And he jumped on the food! He couldn't wait to get into it. Honestly, I have to say he has not yet lost weight although he is getting the maintenance portion for an 8 lb. cat - maybe he is already his Perfect Weight - he is sleeker and slimmer and has more energy. He also enjoys the wet food which I use as a special treat. Thank you for another excellent product Science Diet! March 20, 2014
Rated 4 out of 5 by Cat likes taste Sandy has gotten very picky about what she will eat. I have three bags of other brands, good brands, that she won't eat anymore. Science Diet is the only brand that Sandy has continued to eat. Also, she was having some issues with blood in her stool and the vet suggested more fiber. The Healthy Weight brand had 2x the fiber of other weight management foods. No more stool issues. The food also occasionally goes on sale or I can get a coupon so it's a pretty good value.

Rated 5 out of 5 by Finn LOVES IT!! Even though my cat is only a little over a year old, he has a tendency to be lazy and on the chubby side. I bought the "Perfect Weight" dry food hoping he would like it. He loves it!! And I'm noticing that he isn't all that interested in the wet food anymore, which is fine with me. There must be something about the new dry food that is filling him up more. Regardless, I've always fed Science Diet to all my cats and they've lived a healthy long life, so I plan to keep feeding him this formula and hopefully he will lose a pound or 2, and live a good long life, too. Thank you, Science Diet!! July 2, 2015
Rated 5 out of 5 by Both my senior adult cats are maintaining a healthy weight and are very happy It is a bit expensive - I do feel it is worth it and will continue to use it - but I wish there were more coupons available. September 5, 2014
Rated 4 out of 5 by Excited to see transformation I started feeding this to both my cats a week ago. By the way they eat it you would think I haven't fed them in months. I decided to try science diet "perfect weight" because my male cat Papa Gino is 19lbs and as much as I love fat cats, I can tell he already has some maintenance issues unlike our average sized cat Mama Mia (8-10lbs). I'm looking forward to seeing his transformation. April 29, 2014
Rated 4 out of 5 by Our cat Annie was deemed over weight by our vet. Our little tuxedo cat Annie is short bodied and stocky. Last year our vet told us that she was morbidly obese and needed to get down from thirteen pounds to at least eight. So far she weighs a little shy of eleven pounds. She loves to set and we have to watch her as she will put her face right in the other cat's food( they all eat the diet food too) so far so good. Betty Gamperl July 16, 2014
Rated 4 out of 5 by 13 year old cat approves and is slowly losing weight 13 year old cat approves and is slowly losing weight. Feeding routine is 1/4 cup twice a day through an automatic feeder, based on the label information this is slightly less than what the vet suggested as daily calorie intake. Couldn't give 5 stars as my cat will eat any dry food so can't vouch for the taste, and while the food is a middle / upper in the price range I trust that the company provides quality food at a reasonable price.

Rated 5 out of 5 by My Cars love it...I love the results Our 2 cats Shy Shy and Sparkle are 3 years old, not very active and have gained a little weight over the past year..I decided to give Hill's® Science Diet® Adult Perfect Weight a try. Not only did my cat girls love the taste, it did well in their sensitive tummies and they trimmed down to a perfect weight. I highly recommend this product to anyone who has a cat that needs to lose weight. July 29, 2014
