I've been using this for a few years, with good results. So when my 5-6 year old cat started vomiting everywhere and having diarrhea, I didn't even think to suspect the food, because the bag looked the same as always. A month and a half of trying to figure out the problem, and I finally thought to look into the food, thinking maybe I had bought expired bags, or it was moldy, or whatever. Come to find out, the formula has changed, without any indication on the packaging other than the addition of turkey and greens in the tiny blue strip. Thanks for causing unnecessary distress and weight loss to my cat, ruined rugs, and wasted time.

It appears that my kitties like the food.  One of my babies is Persian & needs the Hairball control & the weight control.  This is accomplishing both.  Plus, the price is right, compared to other brand foods.  I would recommend this for other cat owners.

[This review was collected as part of a promotion.] My cats really enjoy this food, and for the most part, it's pretty easy on their tummies -- including my older girl, who has a sensitive one! It's a great, reasonably priced option that has real ingredients first. My vet has also been approving when I tell her I feed them Iams. This is definitely my go-to food for my girls!

[This review was collected as part of a promotion.] My Iams® ProActive Health™ cat food bzzkit could not have arrived at a better time! My cat's bowl was empty and she was siting next to it demanding to be fed. So, I immediately put Iams® ProActive Health™ to the test. I pulled out two bowls that looked exactly the same and poured equal amounts of the food she had been eating (store brand from an emergency dash to the supermarket to get her fed) into one bowl and Iams® ProActive Health™ cat food in the other. The results were clear; she inhaled the food from the Iams bowl and completely ignored the store brand. Even after she finished the Iams, she did not touch the other bowl! In the following weeks, she continued to eat Iams® ProActive Health™ cat food exclusively. She has had less hairballs and her coat is shinier. She has always been small, but as she aged (she is now 15) she developed a bit of a belly. The other day, I noticed her belly was a bit smaller and she looked leaner. Based on her initial reaction to the food, I think the taste of Iams® ProActive Health™ cat food makes my cat happy. It feels good to feed her great quality food that she loves to eat.

[This review was collected as part of a promotion.] I was given this product to review. My cats are pretty finicky when it comes to their food. They loved it. I’ll continue to test it and see if it helps with their hairball. It’s great for indoor cats like mine. I will definitely purchase this.

This is the food I feed my cats. I free feed them so they can eat whenever they want. Two of them are a lil chunky so I wouldn’t recommend free feeding this if you’re trying to control their weight (obviously) but they’ve never had issues with throwing it up

This cat food is awesome and I've used it for years with all my kitties. It definitely helps reduce the amount of hairballs and keeps my cat at a healthy weight. He loves the taste and gets very upset when his food bowl is empty. At times when I've run out of food and needed to get something quickly, I've purchased a cheaper brand only to find little piles of nasty kitty hairball piles.  As soon as he goes back on Iams, everything is back to normal.

I usually go with generic brands for much everything but this stuff seems to actually have decent effects. We're cat sitting right now and started feeding the new guy this food and his fur quality drastically improved. From course and oily to smooth and silky.

[This review was collected as part of a promotion.] Since I have been using the Iam's proactive health weight and hairball care my cats have not had any issues with hairballs. This is such a positive moment and I am so glad I do not come home to messes of hairballs from the cat during the day. My cat loves the taste and comes running when she see's her food being put out. I am excited to keep it up to see how well the weight portion works.

Something has happened to this food - maybe another unannounced ingredient change - but my two cats, who normally have big appetites and LOVE this food, are barely touching it and now they’ve got diarrhea. I bought a new bag in case that was the problem, but same issue. Last time this happened, we had to go through 6 brands to find something else they would eat; I think this time we’ll switch for good.
