             Experiments performed on animals, simply put, is unethical. A common test used by shampoo manufacturers is the Draize test. Developed in the 1940s, the Draize test involves dropping a substance into a rabbit's eyes to study the eye damage and the rate at which their eyes recover. Rabbits are used in this test because their eyes produce no tears so the substance cannot be washed away. This causes the rabbits severe pain and, in many cases, blindness. In projects lasting months and even years, groups of monkeys were purposely brain-damaged with chemicals and then put through a series of tests. Most of the experiments ended with the monkeys being killed and various body parts analyzed. But before they were killed by the scientists, the animals suffered symptoms which included seizures, vomiting, diarrhea, tremors, and uncontrollable body movements. At Newcastle University, eight cats were used to investigate how nerve messages from the skin on their feet might affect control of their leg muscles. The cats were given anesthetics and arteries in their necks were tied. Most nerves to their left-back legs were cut below their hip, and two wires were pushed into one of their leg muscles to record the findings. The cats were placed with their heads held in a frame over a treadmill - restrained by pins in their hips and clamps on their left back leg. Part of their brain was then removed, and the scientists stopped giving the cats anesthetic. With the treadmill running to make the cat's legs 'walk', the reaction to electrical impulses applied to a nerve from their foot was measured.
             At Nottingham University, five cats were used to research changes in vision sensitivity when the eye moves. A hole was
