According to the ASPCA (American Society for the Prevention of Cruelty to Animals) Iams animal testing is a thing of the past.

We believe that our access inside the headquarters of Iams, one of the world's largest animal-health companies, provides the animal welfare community with a unique opportunity to effect long-term change.

On October 7, 2004, Iams announced an unprecedented decision to move nutritional studies from external contract facilities and universities into three locations: 1) pet owners' homes; 2) Iams Pet Health and Nutritional Centers; and 3) organizations where dogs and cats are already living, such as shelters. This will ensure that dogs and cats are treated humanely during nutritional studies, and it is welcome news from a leader in the pet food industry.

The relationship between Iams and the ASPCA has resulted in many other significant improvements in animal care:
# Dr. Steven Hansen, Senior Vice President of the ASPCA Midwest Office, is a member of the Iams International Animal Care Advisory Board. As a member of the Board, Dr. Hansen has unlimited access to the research protocols and programs that the Iams Research and Development Department is undertaking. This type of access is unprecedented.
# Beginning in the Spring of 2003, the ASPCA began participating in site visits to external facilities where Iams was conducting nutritional studies. Reports on these visits have led Iams to make changes in the housing, care and enrichment of animals involved in Iams' program.
# Dr. Hansen and a broader ASPCA team continue to conduct unannounced external visits to locations where Iams is conducting nutritional studies. Reports on visits are posted on the ASPCA website, www.aspca.org, so that the public has complete access to the results and can learn about the care of dogs and cats at these research facilities. Iams is addressing the team's recommendations.
# Dr. Hansen and the Iams Advisory Board have strongly encouraged Iams to implement an unprecedented individualized program to ensure the well-being of each and every dog and cat participating in Iams nutritional studies. This program allows Iams to tailor its enrichment programs to meet the specific needs of individual pets.

Edit: Would just like to add I'm against any form of testing any product, whatever it may be, on animals.
