Iams Cat Food Review

Available fromPet Circle  

Iams is one of the many Mars brands, and one of the bottom shelf ones at that. It’s amazing the product has such a good name, but it’s not overly surprising when you consider how much Mars have available to spend on clever marketing.

Iams Cat Food Review

When two of the three main ingredients are wheat and corn we know we’re not onto a good start. Cats are carnivorous meat eating animals for heaven’s sake, is that so hard to grasp? No wonder so many cats end up dying before their time.

Even chicken is weighed prior to cooking so effectively loses around 70% moisture once baked into a kibble, so what we’re left with is more filler grains than we can shake a stick at.

It doesn’t stop with the corn either, as the 6th ingredient is also corn.

Ambiguous (chemical?) antioxidants? Ambiguous “vitamins” and “minerals”? And what does “Natural flavours” mean? I know, and trust me you don’t want to.

  1. HEY !!!
    Write about the PET FOOD , and your personal experience with it ,

  2. Hello Iams!
    I am writing to you with a very damaged sense of trust in you as I was once a dedicated customer. I have very picky cats and getting them both on the same diet that I believed to be healthy and did not cost an absolute fortune (expensive, but doable) I found a product that was working. Your brand of Proactive Health Adult Indoor 1+ Years with wild ocean fish and chicken.
    On the bag it is very clear and I quote “1st Ingredient is Chicken” and “concentrated nutrition with high-quality protein”

    I have come to a horrifying revelation today, as most people, I ASSUMED and TRUSTED you where selling me just that.


    your cat food contains: one third expected supplements with 26%supposed actual meat.
    One third filler of non descriptive, useless or suspect ingredients, and one third HARMFUL INGREDIENTS
    with, I might add, Trace elements OF TOXIC TO HUMAN CHEMICALS! seriously?

    Here’s the breakdown (for everyone else’s benefit, you are already well aware of what you do):

    Dried Chicken and Turkey (26%)- this is good

    Maize- CORN = BAD FOR CATS


    Maize grits- MORE CORN!

    dried beet pulp (6%)- VERY BAD!!


    fish meal (5%)- SUSPECT. NON DESCRIPTIVE! Also is this seriously why the packet is labelled as having fish? You have better cause for calling it chicken and turkey mix!


    dried whole egg- Yay! Something else thats good!

    hydrolysed animal proteins- SUSPECT!

    fructooligosaccharides(0.68%)- good digestion. Yay. But less than 1%? Whats the total % of corn hmmm?

    Potassium chloride- this is a treatment for severe kidney problems. I suppose its necessary considering how damaging the rest of this food is!


    calcium carbonate- dietary supplement. Yay.

    Sodium chloride- TABLE SALT. TOXIC

    dicalcium phosphate- CAN BECOME TOXIC TO BODY!

    Trace elements include Mananous Sulphate Monohydrate better known as Manganese Sulphate Monohydrate. COMES WITH A HEALTH HAZARD WARNING along with cupric Sulphate pentahydrate or Copper sulphate pentahydrate!
    Did you know the latter (manganese sulphate Monohydrate) can cause damage to organs and is listed as “for laboratory and manufacturing use only” with warning like “avoid release to the environment ” and “do not breath dust”?

    I feel like you should be sued. Big time. This is criminal!

    • Good to see the link between crazy rants and the capslock key is as strong as ever

      • Good to see morons making useless comments again. It is the internet I understand. You live in a basement and feel the need to draw attention to yourself.

    • Also based on pet circle it’s $37 for 3kg there is much better foods out there with similar or even better pricing, just really have to research the websites selling food and don’t get fooled by the big brands advertising “healthy” or the new buzzword “clean” food.

      Taste of the wild has a high meat food, Earthborn has a high protein food with meat everywhere on the list but it’s not bad, Ivory Coat I like the brand, their fish kibble has helped Rusty but not as well as Blackhawk has. His tear stains are like gone! I will definitely buy that fish and potato as often as possible until they change the ingredients, I hope they never do.

      I guess at the end of the day every food on the best rated list is good and you should check them out online and see their pricing.

      • Cheers for that. Ivory is exactly what I am going for next. I Had them on blackhawk before Iams but my little chellie just couldn’t handle it, the vet had me put him on this attrociousluly expensive sensitive stomack mix and with her advice eventually wound up on the Iams because it wasn’t upsetting him. So basically I had already done the ring around trying to keep my cat fed without loosing his shit (lol) and the other one ok with it. Wish me luck with Ivory!

        • Wishing you luck! I reckon it’ll be just fine, but who knows with dogs or cats these days haha.

    • Suing any of the big brand companies has been tried and tested you could say as almost every single time the company has won 🙁

      The courts keep dismissing the cases for having no proof and what not, but I think their getting paid big bucks to say that to be honest, as the proof is everywhere around us, not every person on the internet is lying about their dogs problems.

      • Absolutely right. The only hope we have is spreading the word. Money talks and the only way to tackle thes guys is hitting them where it hurts- their wallets. If people start seeing this sort of post I put up on review sites etc hopefully they will clue in and buy from a more reputable brand. I know its hard but like anything these days that is too big to handle we have to start somewhere. I’m not the only one kicking up a fuss and hopefully I won’t be the last 🙂

    • Err, you realise this is not the Iams website, right?
      It’s possible that an enterprising employee of the company might randomly stumble across your message and respond, but there are better ways to address them directly.

      • Well spotted. Yes there are better ways I do agree. However this does belong on a review page (this is what this page is correct?) And would you beleive that almost all consumers are oblivious to the points I raised? So in actual fact this is more of an awareness campaign. Thanks for the thought though
