IAMS do animal testing and have done for years.  They keep animals in Not only do IAMS do animals testing, they also keep animals in cages that have apex bars so that the animal cannot stand without pain and their paws slide between the bars.  They cause gingivitis to test their food products' effect on it.  They keep social animals in isolation.  These dogs slink in their cages and no longer respond positively to human contact.  Some look frightened.
