Some tests performed on the animals include spraying chemicals in the animals eyes and injecting the animals with deadly diseases. These tests not only effect the animals physically, but also mentally. Some primates become self-mutilating, tearing at their body and inflicting severe wounds upon themselves.
Animal testing is a practice which many companies do. If you wish to do something about animal testing, you can start by purchasing products that arenít tested on animals. You can find out whether or not they are by reading the label on the product or calling the company who makes it.
