Testing animals are the pathway for medical researchers and scientist to explore and test a medical device efficiency, a therapeutic drug effectiveness for a specific disease, or particular surgical techniques (ex. hip replacement, kidney transplant, heart transplant, etc.). As it is unethical and impossible to test these aspects on humans due to the high error possibilities which could lead to death in some cases, animals would be an ideal alternative for clinical testing due to the biological similarities between human and animals which make it a great model for research and would lead to a results that would work also on human organs. This includes similarities in diseases, physical and psychological emotions. Repeating tests, and injecting with different injections can only be done on animals as applying them to humans would be such a risk. This would be in most cases beneficial for human life and would offer a better and safer medical future. Thus, I don’t think it is unethical, and researchers couldn’t find a better alternative yet.

In one of the surgeries I attended for my research, our rat was depressed after the surgery for around two months under psychological treatment and then we lab members were able to get a better neural recording.
