The 3Rs are the guiding principles for animal experimentation in Switzerland today.
The 3Rs stand for Replace, Reduce, Refine and represent a responsible approach to animal testing. The goal is to replace animal experiments whenever possible. In addition, the aim is to keep the number of animal experiments as low as possible and to only use the necessary number of animals. Lastly, it is vital to ensure that the distress inflicted upon the animals is as low as possible.

Moreover, the experiments should be designed to cause as little distress as possible, by using or developing alternative methods (additional information is available in the section on the 3Rs principles). Anyone working, or conducting research with laboratory animals is obliged to comply with the 3Rs principles. Examples pertaining to all these three pillars can be found in the section on the 3Rs principles.
