My cat is a maine coon cat, and has been brought up on both IAMS dry and IAMS cuts and gravy.
All of her food stores were from the tainted lots and now explains why she has been sick. I took her in about February and she got better, then brought her back about two weeks ago, just before the re-call. The vet until then the couldn't understand how (an otherwise super healthy cat) became so ill. She will be alright now but she went from an 18 lb cat to about 10 lbs. Maine coons are very large cats normally and the vet suggested is why she faired better than some.and the fact I brought her in soon after she was "acting" off.
Even if you suspect your pet ate the food, they should be brought in for a check-up.
