如今,the scientific community is divided into pro-animal testing supporters, and scientists argue that animal testing is lacking in efficacy. I’m strongly against the development of animal houses for animal medical experiments. Experiments on animals reproduce artificially a condition of disease or injury. Several transgenic models are available for cancer drug testing. Many times, the experiments are brutal. They involve laboratory animals in unethical procedures. Moreover, animal testing often has a low scientific power to esteem a medicine's effectiveness and safety
