This product is great and appears to be a hit with the cats My cats love this food, they don't experience the stomach upsets as they do with other foods. I have seven cats and each one eats what they want, when they want. This food satisfies their hunger with smaller amounts. All are healthy and happy, Science Diet comes highly recommended by my vet.

My cats love it!! Can't say enough about ANY Science Diet product!! My cats love all of them! I only have 3 cats that really need this particular one, but I mix it in with the others -- most of my cats are at least 5 or 6 -- so I don't really worry too much about mixing the various ones. ANY Hill's product is great and my cats are living proof that they are much healthier! May 16, 2012
No more picky eaters in my house! My cat, Boo, is very selective in what "he chooses" to eat. I have tried many brands of dry food and even tried mixing brands to try to fool him into eating. Not with Science Diet Adult Longevity! I no longer find food scattered all over the floor! He loves the small size of the nuggets! Me too! No more little pieces to clean up. YEA! May 17, 2012
Science Diet is all my cat wants to eat. My cat Papya has been eating and enjoying Science Diet her whole life. This product is very consistant from bag to bag. She has good weight and haircoat. She still runs and plays like a kitten. She has never had any sickness. I contribute this to good wellness checkups and excellent food. May 16, 2012
Science Diet is a healthy food choice for your beloved pet. Science Diet was recommended to me when I got my cat from the Humane Society 10 years ago and I am extremely pleased with this product. I truly beleive Science Diet is a contributing factor to my cat's great health and happiness. Science Diet will forever be the food I provide to my pets. May 17, 2012
Very satisfied customers! My eldest cat had lost over 3lbs in our last check up and the vet was worried. We decided to change brands as she didn't seem to be suffering from a skin condition anymore that her food her food had been prescribed for and felt that a food change would be the pick me up she needed. We decided on Hill's science diet as our new dog seems very happy with it and the cats had actually been secretly stealing it! We went with the longevity as I want to keep our fluffy friends around as long as possible and as healthy as possible. They absolutely love it! We have an automatic feeder and with the old brand I was only filling it up maybe twice a week at most (I also feed them wet food daily). Now, I can't keep up with demand! They wolf it down like they've never been fed before and I'm refilling at least3-4 times a week. The best part is that our cat gained a pound in her first month on this food and is still climbing her way back to normal weight. Absolutely couldn't be happier. July 1, 2013
Kali loves to eat it right out of the bag I got my Kali from a shelter 5 years ago, she had been eating Science Diet Optimal Care and I kept feeding it to her. We got a kitten later that year and they both love their Science Diet. Kali was 5 when we adopted her and I have switched them to the Active Longevity. Kali loves it so much she, when I open a new bag she will stick her head in and eat right out of the bag! January 24, 2015
