    My cat died of kidney failure after switching to the Iams Urinary Tract food. I'd gotten a free bag of it through one of the product testing programs and thought with his age that it might be helpful to him. Instead, he died after eating it. Looking online, I found that this has happened to a lot of cats. Please keep your cat safe, and don't buy or give food from this company!

    I have two healthy cats, ages 6 yrs old (sisters from same litter). They were adopted about 4 mos ago & we were given bags of IAMS dry food as well as the "snap" packages of wet chicken & beef flavor foods. About a month ago we bought more of both foods & the IAMS "snap" packages included tuna flavor. I thought the cats would like the tuna because when I give them BumbleBee canned tuna (not cat food) they love it. So I put half of one IAMS tuna flavor snap pack down for one, another half for the other at breakfast. (Numbers on bottom of packets 19014 80231 and 1504988.)

    The more active cat came into the kitchen & approached her dish. She stopped about 12 inches from the dish (something she's never done) & began sniffing. It was clear something about the odor did not appeal to her. She came a bit closer, sniffed again, & left the kitchen, the food untouched. The less active cat came in about 30 mins later & did the same thing--stopped a foot away from the food, sniffed, & walked out. I left the food out all day & it remained untouched. Thinking maybe it was just that package with a problem, the next day I put out two fresh halves of IAMS tuna. The cats rejected it again; they wouldn't go near that food. Something is wrong.

      I have 5 older cats and this cat food caused 3 of them to throw it up which is unusual. Won't buy IAMS no more!! Sad. They were a good cat food. Made 3 cats out of 5 throw up. Do not recommend iams cat food. No good.

      I’ve been using Iam’s for approximately 10 years and previously have only had issues with shipping the wrong food. Now my indoor AND outdoor cats have vomiting, diarrhea and are obviously dehydrated as they are drinking copious amounts of water and have become lethargic. I bought the Iams Healthy Adult with chicken through Amazon in the 22 lb bag.

      My cat vomited from this food every other day. Once we stopped giving it to her she stopped vomiting. Not a good brand anymore. Potentially toxic causing vomiting in healthy cats. Bought on Chewy we and she still got sick.

      I have fed IAMS Sensitive Stomach to my indoor cats because one has a stomach issue. They suddenly stopped eating as much and one got deathly sick and started losing weight. Well iams sold out and the formula changed. I swapped to Blue for sensitive stomach and they are eating and the diarrhea and the throwing up stopped almost overnight. They are putting on weight again. I will never trust iams again. Several years ago I lost a cat to kidney disease my vet blamed on iams. Iams was using corn gluten but they had a recall and changed the formula. Guess what, iams is using it again! Also they are using a chlorine salt! Read the labels! Iams lost 30 years of loyalty. They ought to be ashamed of themselves for putting profit before the health of our pets!

      Two bags of food purchased recently in two separate stores, one had insects in the bag and the other was close to expiring. The quality is just awful. And I had to throw both bags out and it's not really affordable and you have to jump through hoops to get your money back.

      I have 2 cats and one of them eats to fast. I tried everything from making sure the dry food had no dye in it. It helped a little. I finally switched to IAMS. My cat who usually vomited hasn't yet. I'm so happy with IAMS.

      My cat was eating Whiskas for the first few years of her life. Then I saw that Iams was supposed to be healthier so I tried it out. Worst mistake ever. After a few days/weeks she started getting allergies and scratching her head open. I tried the anti-allergenic Iams and it didn't help. I tried switching back to Whiskas and it didn't help. Tried a prescription one and that helped a bit but still not completely. Then I had to go to the next level of prescription.

      The Iams cat food completely ruined my cat's life. She can't have wet food or treats anymore and has to wear a cone almost all the time so she doesn't scratch. I've taken her for every test/treatment the vets have to offer but now she has to take a pill every day or two that causes diabetes long term and eat only the prescription food. Even then she still has outbreaks occasionally and the cone has to go back on for a month. She wore it almost a year the first time with a couple of weeks without it every once in a while. It's been a year and a half now and she's had maybe 2 months total without having to wear a cone. Poor Kitty. The Iams obviously initially triggered the allergy. I wish I could sue Iams but I know I could never prove it in court since I don't have a paper trail. Please stay away if you care about your cat.
