why do you feel this response is the most ethical and why do you feel the way you do about animar research? D. Animals clearly feel, and most, let's say all vertebrates, are aware of their surroundings and feel pain. They have as much right to live as we do. Furthermore, we are the custodians of these animals in many cases, and their well-being is our responsibility. Most testing is pointless status quo that keeps grant money coming in but...
