IamsIams may be the best known pet food out there today, and maintains a very large group of customers who are loyal to them, even after the huge pet food recall that stained them a bit. They have a ton of varities out there, so I’ve chosen a basic one: Original with Tuna. Let’s see how it does…

Iams isn’t a cheap food, and so I’d hope the ingredients would reflect that. Unfortunately, by-products are the very first ingredient and primary protein source of this food. Then, we’re confronted with two corn sources directly afterward, which we know by now aren’t beneficial to cats at all. Having filler as the 2nd and 3rd ingredients doesn’t really instill a lot of confidence. It’s also a certainty the corn ingredients will artificially inflate the protein levels in the food in a form our cats struggle to digest. Not good.

At least they have tuna as the 5th ingredient, so that’s one good protein source, but if you’re buying something with “Tuna” on the label then don’t you want it higher than 5th? It seems a little disingenuous to have a bag labelled “tuna” when “chicken by-products” are first and foremost.


Dried beet pulp’s value as a fiber source is often debated, so I tend to leave that one alone. It’s high in sugar and can cause colon issues over if consumed in high quantities over a long period of time. Brewers yeast is a bit controversial, but recent studies show it has marginal nutritional value to cats. It’s still a by-product of alcohol making.

All in all, it’s a very expensive food, so don’t you want to get what you pay for?

Where to buy?

What’s good about this food….

Tuna is 5th, fish oil included.

….and what’s not so good.

By products are main protein source, way too much corn, insufficient real meat.
