These feline prisoners peer out from behind the bars of their cages, vying for the attention of our investigator.

Animal experimentation is a bloody, violent, and deadly business. Those who don’t want to get their hands dirty and those who prefer to hide behind the cloak of “deniability” hire contract laboratories to get the job done.

Our recent investigation into one of these contract facilities identified two major producers of dog and cat food—the Iams Company and Menu Foods, Ltd.—that paid others to do their dirty work. Still, there were others lurking in the shadows of this facility, including companion animal care companies, drug makers, and universities.

We wrote to the institutions listed below to share the results of our investigation into the laboratory/animal dealer that they—along with Iams and Menu Foods—were doing business with. We asked the manufacturers of dog and cat foods and ingredients to stop using laboratories to conduct experiments on animals and, instead, to rely on laboratory analysis of formulas for information about nutritional composition and to use dogs and cats whose human companions have volunteered to monitor them at home for palatability studies.

The millions of dogs, mice, rabbits, and other animals suffering in laboratories need your help today. Please click here to support PETA's vital work to stop this cruelty.
