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.

  • Love this product - recommend it!

    By on

    We have 4 cats all indoor. 3 of them are overweight and one of them is really chubby and always had a really bad stink to her. One month on this IAMS product and we notice significant increase in activity in all the cats, more rambunctious and they are actually slimming down! The stinky cat isn't so stinky any more and she was the chunkiest one. They love this food and I am a true believer in this product!

  • Great product! My cats love it!

    By on

    I would recommend the Iams Weight and Hairball Dry Cat Food because i can feel confident that they are getting all their nutrition needs met while not worrying about them eating alot of extra unneeded calories. They really seem to love it too. Cats can be picky about their food but both my cats love this dry food. It meets all my requirements for a dry cat food- low calorie, reduces hairballs, easily digested, and a good source of protein. I would definitely recommend it to all cat parents!

  • A good food that satisfies a broad array of cats.

    By on

    I certainly cannot be mad at the amount and pricing for this product! I have a number of cats that I care for and some have rather sensitive systems (frequent vomiting and/or hairballs). This food certainly helps them out and I can tell they feel much better - plus...the added bonus of not having all those messes to clean up is nice.

  • We love Chewy!

    By on

    We have 5 dogs and 2 cats so we buy lots of pet food. We discovered Chewy and thoroughly enjoy their range of products and service. Using Chewy's auto-delivery has saved us time and money plus it is delivered right to our door. I would recommend to everyone!

  • Our Cats LOVE this food!

    By on

    Hi, our four cats were on another food that was part of their 'wellness'. Well, since our cats were placed on IAMS they actually lost some needed weight. They are eating very well and love IAMS.

  • None of my 6 cats eats it :-(

    By on

    Bought this hairball formula a while ago. Unfortunately, all our cats just sniff at it and turn away from it.... It's been sitting there and no cat would eat it. We had to go back to our old formula which we also buy from Chewy.

    This is a great product. My cats really love it. They continually munch on it even after they have eaten and it does curb the hairballs. My Annie-girl has stopped throwing up

  • My cat likes this dry food

    By on

    I feed my cat both dry and wet food. She eats all of the dry food and leaves some wet food in her dishes. She is mostly an indoor cat, but sometimes she likes to go cruise the perimeter.

  • Excellent product produced by Imas

    By on

    We have used this particular product for years. At one time we had 3 cats now just one. Normally purchased from local stores. However, it is so nice to have it delivered right to our front door. I highly recommend if you have older cats.
