PETA has raised false alarms about many companies before.
I feed my cats IAMS and they love it. I've tried others and they had problems with vomiting. They hate Nutro. I've also tried Feliday. They didn't like that either. I take everything PETA says with a grain of salt. They very quick to point a finger yet PETA themselves have been found guilty of killing cats and dogs and freezing their carcasses, because they believe all animals should not be confined.
