For 10 months in 2002 and 2003, [[People for the Ethical Treatment of Animals]] (PETA) conducted an undercover investigation at [[Sinclair Research Center]], a contract laboratory for Iams pet food. The investigation found dogs who had gone crazy from intense confinement in barren steel cages and cement cells. Sick dogs and cats were left to languish in their cages without veterinary care; including dogs who had had chunks of muscle hacked from their thighs. Dogs had also been surgically debarked. The USDA found 40 violations of the Animal Welfare Act; <ref>[http://www.nal.usda.gov/awic/legislat/usdaleg1.htm Animal Welfare Act and Regulations], USDA[[U.S. Department of Agriculture]], August 2003December 2009</ref> including failure to provide veterinary care, pain relief, adequate space and proper training. Sinclair Research Center paid a penalty of $33,000. <ref>[http://www.iamscruelty.com/pdfs/USDA_Sinclair_Labs1.pdf Sinclair Research Center], USDA Report, October 2006</ref>, <ref>[http://www.iamscruelty.com/ Animals Still Suffer at Iams], [[People for the Ethical Treatment of Animals]], accessed January 2009</ref> After intense pressure from PETA and its supporters, Iams agreed to sever its ties with Sinclair and end invasive and terminal experiments on dogs and cats.
