This is just so shocking, heartbreaking and unbearable to watch. What is wrong with people who can abuse helpless animals so readily without remorse, regret or any natural feelings of compassion? What kind of mentality do such people have? I think it is the experimenters who need a psychiatric assessment and treatment for psychosis. There has to be something seriously wrong with such people. This has to stop now. I hope as many people as possible share this and send the message to NIH Labs.
