Science Diet Cat Food
100% Precisely Balanced Nutrition

Hill's Science Diet cat food provides key nutrients that are in amounts within an optimal range for your cat, and is precisely balanced for their nutritional needs. We develop products with the precise balance of 50 nutrients based on life stage, lifestyle, size or special care needs. We carefully avoid too little or too much of certain nutrients.

America’s Pet Nutrition Experts Since 1939

Balanced pet nutrition has been our passion for more than 70 years. Over 150 veterinarians and pet nutritionists are involved in the development of our products. We make every bag of our dry pet food with the highest quality natural ingredients. These ingredients must meet our strict requirements for purity and nutrient content, which exceed industry standards.

High-Quality Ingredients for a Happy, Healthy Life

The right nutrition can help a cat's health, energy level and quality of life. Hill's Science Diet cat food contains nutrient-rich, high-quality ingredients like chicken, whole grains, and multivitamins to create nutritionally balanced food. Every bag of Science Diet provides key nutrients in amounts within an optimal range for your cat.

Transition Tips

Begin the transition by mixing the current food with the new pet food. Gradually decrease the amount of the current pet food while increasing the amount of new pet food. Continue to do this over a 7-day period. Transitioning slowly can result in fewer digestive issues and better acceptance of the new pet food. For finicky, older, or pets with health conditions, the transition time could take 10 days or slightly longer.

I got my cat at a shelter and they feed this to the cats there. My cat Wanda loves it. Never any waste and it makes for a cleaner litter box. Cuts stool odor down 90%. No dyes that can stain either. Keeps Wanda happy and very healthy.

I have used Science Diet for over 20 years now. My cats coats are soft, and shiny. I recently adopted a rescue that found me, for the first week, her litter box stunk so bad, it made me gag. Finally when the old cat food was out of her system and she was 100% science diet, it was a huge difference in the smell!! The price seems high compared to other brands you find in the store, however, it really isn't. Cats are nutritionally satisfied and the food goes a long way. It averages 10.00 a month for one cat. Not bad. I won't feed anything else.

My cats have been on Hill's Science Diet since they came home as kittens. This food is great and keeps them very healthy, it's what the vet has always recommended and I've stuck with for my cats. I get the big bag because it's easier to store it in a large air-tight container near their food and not have to worry about buying food every other week or so. So glad to see this on Amazon Prime now, I used to have to go out of my way to speciality pet stores just to get it as places like PetCo out here don't always carry it.

EDIT/UPDATE: My oldest cat is turning 6 this year and my younger one will be 4 later this year. Both are still very healthy, active, and not overweight.

I have always found Science Diet to be a superior pet food brand. All feline members of my family eat it and are in optimal health. The small kibble is particularly nice in that it takes them longer to eat it, and they are less likely to vomit from eating too quickly.

My cat is picky. He also gets an upset stomach over other varieties of cat food. However, Science diet adult optimal works best. It was used at the shelter we bought him and he loves it and this big bag, as long as it is put in a Gallon sized tupperware type container is about half price of any pet food store.

Size Name: 17.5-Pound Verified Purchase
This cat food contains a lower level of magnesium than the "supermarket" cat foods. Low magnesium levels help to prevent urethra problems, especially in male cats due to their more narrow urethra. I would rather pay the higher price for this brand of cat food than bring my cats to an emergency vet in the middle of the night because their urinary tract gets blocked, not to mention the aggravation caused to the cat. Other brands of low magnesium cat food include Iam's and Nutro-Max. Hill's Science Diet food is round-shaped, rather than "hooked", which makes it easier for one of my older tooth-challenged cats to swallow.

The price was better than other places we checked AND with free shipping to our door--what a deal! We've tried the pet chain stores over the years and other retail stores as we've been cat owners since 1975. We stay 'educated' regarding the brands we use. As is with many of us now, every penny counts. The site is user-friendly and our order was arrived in a very timely manner.

We've shopped at Amazon.com over the years for things other than cat food. I don't recall EVER having a problem. We come back as often as we are able. The prices and service are the best!

We buy this from Amazon because it's cheaper than our local big box pet store that rhymes with Let-Go, and also because it shows up at the doorstep with only a click (and a debit to my bank account). I even tried it myself; as cat food goes, I've had worse!
