IAMS Adult Cat Food Products
Healthy Weight

Healthy Weight

Protein is a key ingredient in IAMS cat food recipes. IAMS is made with high-quality protein to help your cat maintain strong, lean muscles. Animal-based proteins like chicken, beef and salmon can help your cat maintain healthy muscle structure and support an ideal weight. And they naturally provide all of the amino acids that cats need to thrive.

Playfulness and Energy

IAMS delivers a customized mix of protein and carbs to keep your cat energized and ready for pouncing and playing. As carnivores, cats need a diet that's high in animal proteins with the ideal ratio of protein to carbohydrates to maintain a healthy energy level. Cats on an IAMS diet are getting essential amino acids, including taurine, plus the amount of carbs they need for hunting feathery toys.

Playfulness and Energy
Healthy Digestion

Healthy Digestion

Getting the right amount and type of fiber is important for your cat's digestive health. IAMS uses a proprietary fiber blend that includes prebiotics and beet pulp. Prebiotics feed the good bacteria in the gut, and beet pulp is a great fiber source that promotes a healthy digestive tract. Every IAMS recipe is tailored to your cat's nutritional needs with the proper level and right kind of fiber for healthy digestion.

Rated 5 out of 5 by Ian's is the only thing I feed my cat. The Chewy website is going to be at the top of my list! Good prices and excellent delivery time. I received my order 48 hours after I submitted it! December 24, 2016
Rated 5 out of 5 by My cat Morris loves his new food. Thank you. My Morris loves his new cat food. Great for my cat who is almost 13 years old. Meow. December 20, 2016
Rated 5 out of 5 by Great for elderly kitties!! Sylvia, my 19 1/2 year old rescue kitty, has been eating this food for several years. Before that she was on other Iams formulas since she was an infant. Since it's made especially for cats over 11 years, I'm comfortable providing it as her only dry food. She also gets wet food it every day but her dry is Iams for over 11 year old cats. I feel that it's helped her reach her ripe old age!! The picture is of her curled up on the heat mat for plants during one recent winter. Didn't like the mat for animals but LOVED the plant one!! Silly kitty!! December 8, 2016
Rated 5 out of 5 by Three cats in the house & they LOVE this product. My cats were being finicky about their dry food. I bought IAMS - Lively Senior Dry Cat Food and they are chowing down! December 15, 2016
Rated 5 out of 5 by Two thumbs up My guy is going to be 14 this year so i just moved him to the senior from the pink bag for mature. Seamless transition and he loves it. He has a full bill of health. December 15, 2016
Rated 5 out of 5 by My two senior cats love it! My two senior cats love it! They are both 11 years old still fairly lightly and running around like kittens and they eat it up as fast as you can put it down. Chewie.com has the best price and usually has it in stock which he received the very next day after ordering. It's hard to find this particular size and most mortar and brick pet shops/stores. One of my two cats has a bit of a sensitive stomach so I buy a bag of the large size lively senior and a bag of the same size of the sensitive stomach both from Iams mix them together and they are happy cats purring all the time! Their vet was impressed when I told her what I was doing with the two because of my shorthairs sensitive stomach. I highly recommend to recommend Chewie.com for all your pet food and accessories purchases and thanks for the fast shipping! October 12, 2016
Rated 5 out of 5 by Foods ok but this rocks Chewy customer service! I had ordered another product and had misgivings so they said keep it, order the right one and shipping is free! WOW. November 23, 2016
Rated 5 out of 5 by Great Food Healthy choice for pets. I really like this food. Iams is a really good choice for dog or cat. November 15, 2016
