Rated 5 out of 5 by from Hill's Science Diet Adult Light for cats is the only brand I'll choose. This product comes in a dry bite size that is easy for my cat to eat. I originally had her on regular Prescription Diet, but since she's an indoor cat and has limited exercise, she started to gain weight. My veterinarian suggested that I change her to the Light formula. She has maintained a healthy weight since that time. I feed Hill's food because my cat loves the taste and it's recommended by my veterinarian. This food may cost a little bit more than some other brands, but I feel like the company is trustworthy and always puts forth a consistently good product. I feel that my pets are worth it. After all, they're just like family!

Rated 4 out of 5 by from Cats love the taste We have two cats that we adopted from friends at different times. We got our female first and she was used to a different brand of food. We wanted to get her something healthier and chose Science Diet Light since she was a little chubby. When we tried mixing the two dry foods together to slowly ween her off of her previous food, she ate around her old food, and only ate the Science Diet pieces. The same thing happened when we brought our male cat into our home. He absolutely refused to eat any of his old food and only ate the Science Diet. Even now, months later, they still try to claw open the bag to eat to their hearts content. Feeding time is their favorite time.

Rated 5 out of 5 by from May 17, 2012 When we adopted our two kittens, Belle and Syman, they came home from their shelter with a bag of Hill's Science Diet Dry Kitten food. They LOVED their kitten food, which we gave them until they were a year old. At their 1 year vet visit, our vet noted that they were at the top of their weight range. He suggested that we give them Hill's Science Diet Adult Light food. When we switched them to the Adult Light food they immediately took to it. Their coats are shiny, and I'm happy to say their they've both actually lost a pound. Hill's Science Diet Adult Light helps keep our babies happy, and most important, healthy!

Rated 5 out of 5 by from Great for weight loss I have fed my cats Hill's Science Diet for quite a while. When the vet said that Lucky needed to lose a few pounds, I switched him to the diet formula. He lost about 2 pounds in a year (would have been less time if I could have figured out the right amount to feed him sooner - I didn't want to starve him - he was used to free feeding). I contacted the Hill's people who informed me of the correct amount to feed a 17-pound cat. Now he's looking good! And now he's used to being fed a certain amount at the same time every day. Of course, he still gets he treats.

Rated 5 out of 5 by from Wonderful product! The vet told us Oskar should weigh 9# not 15 so we reduced the amount of another brand of food he was getting per the doctor's instructions. This did not result in a weight loss so I got Adult Light to try. After the first month, he is down about 1.5# and I can see a waistline! While I think 9# is a little light considering his length, we will stick with this food and I will reassess when he gets to 12 pounds. He loves it and so do I. I wonder if it would work for MY weight loss!?!?

Rated 5 out of 5 by from My 3 cats love it! My 3 cats were starting to become roly-poly, so I switched from the regular dry cat food to this Science Diet Light. They all seemed to prefer this to the original Science Diet they had eaten for years. In fact, one of the cats will not touch any other food-even table scraps! They have energy, are playful, and 2 of the 3 have lost the pot belly (still working on the 3rd cat!) I also feed the neighbor's outdoor cat on occasion and he comes by to patrol our yard for moles and get a handful of the dry pellets. He loves the treat! The pellet size is perfect for my cats and they eat every morsel. Vet appointments confirm the health of my cats. I would highly recommend this food for cats with a tendency for overweight.

Rated 5 out of 5 by from Our cats thrive on Science Diet We have four adult cats and they love Science Diet. They are all indoor cats, and a couple of them are a little extra "fluffy" so we feed them the light food. Our household has been hit particularly hard by the economy, so we tried some less expensive food for a while. The cats ate it, but there were a lot more stomach problems and their coats were as thick and shiny. So, we decided to cut back elsewhere and now only buy the Science Diet foods. With our local pet store's loyalty program and Science Diet's coupons we still do really well and we feel much better about how we are caring for our furry kids.

Rated 5 out of 5 by from Perfect for my Felines! I purchased this product after I got a coupon from the Hill's website for it. My Maine Coon "Frank" is 5 years old and he's kind of on the plump side, I won't lie. I bought this in hopes that it would be more filling and cause him to loose a few pounds easily yet healthy. It worked! I feed him 3/4 cup all day and 1 can of wet food and he has lost 3lbs. He enjoys the taste and because it's Hill's, I know the quality is amazing. The coupons always help too :)
