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.

  • 22lb. bag is cheaper than 16lb. Bag

    By on

    I ordered Iams Weight Control dry food for our cats and it was cheaper than our local pet store, plus free shipping. The shipping was supposed to be 1-2 day shipping, but, it took several days to get it. The winter weather could have been the reason. Don’t wait until the last minute to order food! Also, I tried to use a $15 coupon and it would not let me use it. I will order, again from Chewy.

  • Not a big hit

    By on

    We have 3 senior cats whom are not picky about food, until the last month. I always gave my cats friskies indoor, but wanted something a bit healthier with less fillers. 1 cat likes this food, the other tolerates it but meows for something different and my 3rd pretty much hates it...she refuses to eat it, has lost TOO MUCH weight....she now sneaks our lab/rotts dog food because she dislikes this so much....i will get her some of her old food just so she starts eating cat food again, but Im trying to decide if I want to switch back to friskies or try a different brand.

  • I'm still a little unsure.

    By on

    My cat likes this food. I used science diet when he was a kitten and when we made the switch to adult food I went with this. He eats it fine but he seems to eat WAY more of this than he ever did with his kitten food. I'm not sure why that is or if I'll get this food again. I might try something different to see if he eats as much of that.

  • Quality products

    By on

    Items you buy are received fast, very convenient, don't have to run out to store to buy my pets food and supplies now. They do however need to change commercial, says free delivery, one would assume all orders. But it has to be close to 50 dollars before free shipping kicks in. Other than that, I am happy with Chewy.

  • Not the best for the price... didnt control my cats weight.

    By on

    Bought this for my cats because my family told me that iams is the best food out there. I now disagree. Ive come to realize that for the price the ingredients arent very healthy... and my cats weight didnt budge. Shes lost more weight now that that shes on a regular food from a different brand than she did on this. For the price point I expect better quality. Ive found that quality in another brand. It didnt have any negative affects on my cat, so thats why I rated it a 3, not a 1 or 2.

  • Super Food

    By on

    From the moment I got this food, my cat did not want anything else. I had a variety of treats available but he no longer wants them. This food is a little pricey and money is a problem, but if he stays just on this food I'm saving money! And that's to the good. Only had the food a week and he's already showing extra energy and I think he's slimming down a little. Love it!

  • Love this Cat Food

    By on

    This cat food is great! I have two long haired cats and one short haired and this food works great for them. They have tried other foods and those tend to make them sick or cause them to have horrible hairballs. I would 100% recommend this cat food to anyone that has a ragdoll or any longhaired cat. They love this food and I feel good knowing they like it and it isn't going to make them sick.

  • No hairballs from my cat!

    By on

    The "no hairballs from my cat" is enough in itself. My cat is not finicky at all, but the fact that she never has hairballs is enough to keep me feeding her this food. I'm not sure if the food has anything to do with it, but I'm not going to deviate from something that works.

  • Cats unenthusiastic about IAMS

    By on

    I keep trying to find the best food for my crowd and the IAMS suits their bodies--they act like they feel better for the most part, but they don't after the food the way they did their original kind. I may try another IAMS type since they like the other concentration at XMAS.
