從2002到2003年，將近10個月的時間，PETA的調查員隱藏身分在Sinclair Research Center，受僱於Iams（愛慕思）的實驗室裡工作。PETA調查員發現在Iams寵物食品清新、健康的包裝下，隱藏的是黑暗且骯髒的秘密。在實驗室，被關在鐵籠裡成天對著水泥牆的狗狗瘋掉了、大腿肌肉被砍掉的狗狗成堆地被丟在骯髒、油漆斑駁的地上、狗狗被割掉了聲帶、生了重病的貓狗在毫無獸醫關照的情況下被扔在籠子裡繼續受苦。
美國農業部審核了PETA提出的抗議後表示該實驗室確實沒有提供獸醫照護、沒有提供受苦的動物麻醉或止痛、沒有提供足夠的空間、沒有做好員工教育訓練，該實驗室同時違反了其他40項聯邦動物福利法規範。Siniclair Research Center付出美金$33,000元（相當於一百零五萬六千元台幣）的罰款。
1. Iams順從壓力，切斷與Siniclair Research Center的關係
根據Iams表示，實驗中大約70%的動物在家中與飼主同住。在這些實驗中，飼主自願讓寵物在家中居住，參與食品營養成份的實驗。透過訓練，飼主可以輕易 地餵食寵物，並採集寵物的糞便以供實驗室作為參考指標。「居家實驗」已經過奧克拉荷馬州立大學PetSci program證實是有效的。
Iams 沒有停止以其他（非狗貓）的動物進行侵入性的實驗。Iams贊助Purdue大學將近$200,000美金來進行一項長達兩年的實驗。實驗過程中，老鼠 的尾巴被黏在籠子頂端，而老鼠的後腿部懸掛在空中。這項實驗的目的是為了造成肌肉萎縮。當PETA提出抗議後，該實驗提前終止。

For nearly 10 months in 2002 and early 2003 , a PETA investigator worked undercover at Sinclair Research Center , a laboratory hired by Iams , and discovered a dark and sordid secret beneath the wholesome image of the dog - and cat-food manufacturer . Dogs had gone crazy because they were confined to barren steel cages and cement cells , dogs were left piled on a filthy paint-chipped floor after chunks of muscle had been hacked from their thighs , dogs were surgically debarked , and horribly sick dogs and cats were neglected and left in cages to suffer without any veterinary care . Footage shows that Iams representatives toured the facility and witnessed dogs who were circling in their cells and sweltering in the summer heat . Iams knew the truth yet did nothing to protect the animals .
The U.S . Department of Agriculture investigated PETA's complaint and agreed that the laboratory had failed to provide veterinary care and pain relief to suffering animals , failed to provide animals with adequate space , and failed to train employees—along with nearly 40 other violations of the federal Animal Welfare Act . Sinclair Research Center paid a penalty of $ 33,000 for its violations .
After intense pressure from PETA and its supporters , Iams agreed to make the following significant changes in its testing program :
• Iams bowed to pressure and severed its ties with Sinclair Research Center .
• Iams ended all invasive and terminal experiments on dogs and cats .
• Iams agreed to begin conducting humane in-home tests for palatability studies .
According to Iams , about 70 percent of the animals now in its tests reside at home with their families . In these studies , people volunteer their companion animals to participate in food and nutrition experiments from the comfort of their own homes . The human guardians can easily be trained to feed the animals and properly collect fecal and urine samples for laboratory analysis to determine the quality of the animal's food . " In-home " studies have been shown to work and have strong scientific support , as shown by the successful PetSci program , which was developed by Dr . Charles Abramson and Dr . Timothy Bowser of Oklahoma State University .
Even so , Iams still keeps up to 700 dogs and cats in its Dayton , Ohio , laboratory for non-invasive nutritional studies . They claim that this laboratory provides a decent environment for the animals , but they refuse to allow a PETA representative to see inside . Iams claims that some studies are too complex for in-home programs , but PETA urges Iams to collaborate with veterinary clinics for studies such as these . Veterinary clinics regularly see patients who suffer from ailments that a particular dog or cat food might help alleviate .
Iams has also refused to end invasive experiments on species other than dogs and cats . For one study , Iams gave Purdue University nearly $ 200,000 to conduct a two-year study in which experimenters taped the tails of mice to the tops of cages to keep their hind legs suspended in the air . This was done to cause muscular atrophy—the wasting away of muscle tissue . When PETA protested , the experiment was cut short . I
Iams has also fought the release of information from a public university that had conducted a study funded by the company in which a painful disease was induced in dogs . What was Iams hiding ?
Iams has made progress , but as an industry leader , it must send an even clearer message : No animal deserves the fate of those who remain in their laboratories . Safe , healthy cat and dog food does not require harming cats and dogs .
PETA continues to press Iams to ban conducting and funding invasive or terminal experiments on all species and to adopt 100 percent humane , non-invasive , and cage-free " in-home " testing , as many of Iams ' compassionate competitors have done .
Until Iams agrees , we urge consumers to purchase dog and cat food from companies that do not test on animals . In the meantime , read about some other ways you can help the millions of animals every year who are abused and inadequately cared for , all in the name of research .
