Animal testing is cruel and inhumane treatment. Some experiments on animals have a very high risk that will be harmful to the animals or even cause the animal death. In U.S. laboratories, animals more than 100 million are killed for biology lessons, drug, food and cosmetics testing such as dogs, cats, rabbits, hamsters, pigs and monkeys. The animals are hurt during the testing because they endure chemicals dripped into their eyes and injected into their bodies. They are addicted to drugs, forced to inhale toxic substances, blinded, burned and infected with disease viruses. The testing on animal is the processes causes pain or suffering and reduces their quality of life in other ways, thus the animal experiment has the same result as killing as test on animals.
