 | Are researchers using more and more animals every year? |  | The number of animals used in research has actually declined in the past 20 years. As technology advances, researchers are able to rely on computer models and other methods instead of animal testing. Some estimates show a reduction in animal use as high as 50 percent. Since 1967, the number of cats used in research has dropped 66 percent. |
