I recently filled in a big cat food survey and had to answer a million questions (seriously, like do I shake the dry food pack to get their attention) what food I feed, what food I used to feed, what impressions I have of food, why I dont feed some of the ones I used to - and it asked me why I chose IAMS as a brand I would never choose to feed my cats, so I told them
I also voted them lowest in all the "how you perceive these brands" questions.
Hope someone from IAMS reads my answers and I hope some other people answering said the same things!
