What is the process of animal testing?
In these experiments, animals are forced to eat or inhale substances, or have them rubbed onto their skin or injected into their bodies. The animals are then subjected to further monitoring and testing before almost always being killed, so that researchers can look at the effects on their tissues and organs.
