I completely agree. My area of expertise is experimental mechanics, and I sometimes help with testing material properties of animal tissue during pre-clinical trials. In academia (I have no idea about commercial companies, but I suppose it’s similar) the ethical side of animal testing is taken very seriously. The number of animals used is typically absolute minimum needed for statistics, and testing is planned in such way as to cause minimum possible suffering to animals. These requirements are also very formalized, the plan for testing is reviewed by with ethical commission and rejected if it’s unreasonable.
