Rated 5 out of 5 by from i LOVE this pet food i've never believed in spending extra money on pet food, and i don't usually do product reviews. But i'm doing so now, that should tell you something. The shelter I adopted my cat from gave me a bag of your food and suggested i wean my cat off the food she enjoyed before i started a new brand. I planned to do that, but when i realized how long this food lasted i realized it was a good value, and when i saw how my new cat pooped i knew it was good for her too. the waist is odor free and VERY little too boot. Her coat is like magic and three years later you have a customer for life and happy cat too. I hope you continue what ever program you have to make your food available to shelters it's good for pets, it's good for your marketing too.

Rated 2 out of 5 by from reformulated food rejected by cat I want to begin by stating that I have consistently purchased Science Diet (Indoor, and/or hairball control) for 4 years, which my cat appeared to have enjoyed. Upon realization that my cat stopped eating the food on Sunday, November 17, I thought she was feeling bad. Last night I provided her with a different type of food, which she devoured. I thought there might be an issue with the new and improved formulation, which led me to this website. From a review of other posts, it appears that this is not an isolated instance...If my pet does not adopt to the new formulated food, HIlls will lose an established customer to another brand and I will have to provide the two bags of food to the area homeless felines...

Rated 5 out of 5 by from Food my cats love I have fed my cats the indoor cat food since a young age. Ever since I adopted my cats from a shelter they have eaten ravenously like they don't know when they will get their next meal. When one of my two kittens was about 9 months old and already weighed 12 pounds I was concerned she was going to be overweight so I switched them from the science diet kitten food to the adult indoor (with the advise of my veterinarian) because of the reduced calories. This seemed to work and the one cat never got over 12 lbs. I prevented them from becoming overweight by feeding the indoor food. All of my cats are indoor only and weigh around 9-12 lbs between all four of them.

Rated 2 out of 5 by from Cats Hate New Improved Food My cats loved their Science Diet Indoor food until I opened a new bag a couple of week's ago. Neither of them appeared interested in eating the stuff, including our adopted feral cat who usually eats anything put before him. They would pick at the food but never cleaned the bowl in one sitting. Was about to call the vet when I decided to check the bag to see whether the formula had been changed. Bingo! "New and Improved," says the label. They are slowly realizing that it is eat this or........... Wish I had realized there was going to be a change in the formula. I would have mixed the old with the new for a week or two.

Rated 1 out of 5 by from new formula My cats don't like the new formula that came out early this year. In fact they throw it up quite often. I'm not sure if we got a bad bag or what. They have enjoyed science diet their whole lives, but the new formula is not working for them. It looks drastically different than the old formula.

Rated 2 out of 5 by from New and Improved formula I recently purchase a bag of the "New and Improved" Adult Indoor formula. This is the second bag I have purchased. My kitty happily ate the first one. The color looked different but I thought "oh well". My cat will not eat it ---she gently tosses it out of the bowl and covers the food with the towel that is under the dish. Something is not right--I will be taking it back to the store.

Rated 5 out of 5 by from Great for multiple cats! I have 5 indoor only cats. I love this food because all of them like it and I like the shape. I have one cat that eats quickly and often does not chew, which then causes him to throw up his recently eaten food. The shape of this food requires him to chew it, which results in less spit-ups. I have noticed that when they do cough up a hairball there is less staining of the carpet, I do not know if that is an intent of the food, but it is a nice side effect. My cats love it so much that when we open a new bag they all come running to get some, and fight over who gets it first.

Rated 1 out of 5 by from Everyone hates it! I always feed Science Diet, although not this variety but when I saw a bonus sized bag I thought I would try it for two of my cats. Put it out along side of their usual and it went untouched. I thought for sure if the old variety (Optimal Care) was gone they would eat the Indoor. Nope! Instead they went to raiding the Senior food that my two elderly sister cats eat. So now I will have to take it back to the store (which is a pain!) and get the kind they like. Can't really give it any stars although guess I can't submit it without giving it at least one.
