However, many people are concerned that animals are suffering unnecessarily and cruelly. They do not believe that every new drug needs to be tested on animals, especially with the huge database of knowledge and modern computer models. They also are worried that many animal tests are ineffective, pointing out that some drugs had to be withdrawn from the market despite extensive testing. They particularly feel that animal testing should not be used for non-essential products such as cosmetics, shampoos, soaps, and cleaning products. Furthermore, some people would like to see certain tests replaced and more humane methods used.We need to make sure that the millions of animals who are used for testing new products are treated with the minimum of suffering. Although some animal testing may be unavoidable at present, treating our fellow creatures as mercifully as possible will demonstrate our humanity.
