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.

  • Works for my boy

    By on

    My cat been an Iams cat all his life. At the shelter I got him from that's what he's been fed and while I have tried other brands that were very much hit and miss. This is the brand that he is never fussy about and will lick his dish clean after or in between meals. Now that he is an older I have slowly been transitioning to this full time from the Iams adult indoor/hairball variety and it's working so far. He's still a happy bratty old kitty.

  • First time to use this Mature Iams

    By on

    My little tabby has always been a "selective" eater. She has never eaten much and I put several different feeding stations for her to entice her with different foods. Have yet to find anything that she will eat well and she is over 16 so she is losing weight. I tried this because she does eat IAMS Senior. Not sure what the difference is but she will not eat the IAMS Mature. I also feed several stray cats and they too do not take to the IAMS Mature as much. They are grateful to get any food, but this is not one they gobble down.

  • Efficient!

    By on

    I was unable to find this food in the pet store locally, so I was going to order a bag from the store. I decided to come home and check out Chewy. I was able to order it from Chewy and get it quicker by mail than the store was going able to order it in for me! That's service!!! I'm now choosing to order all of my monthly pet supply needs through Chewy!

    I am so glad I shopped on Chewy.com. I couldn't find this food and my cats won't eat anything else. I will definitely be a regular customer.

  • Senior cat loves it!

    By on

    This is the 2nd time ordering it and my cat still loves it. We have to limit the amount of all food he eats and this he has sniffed out when even hidden in out huge walk in closet so now we have had to find a new hiding spot for it, shh, it is in a cabinet in my wall unit with a bunch of old books and a towel sprayed with vinigar to hide the smell. If he smells it and knows where it is he will continuouse cry and paw until he gets more.
