Dear participant,

Thank you for taking the time to complete our online survey. This survey is part of a master’s thesis in the Laboratory Animal Science program at RWTH Aachen University. This survey focus on the living conditions among individually housed male mice. The aim is to gather valuable data for the Swedish 3R Center and the German 3R Competence Network in North Rhine-Westphalia (NRW) to further promote the 3R principles (Replace, Reduce, Refine) in laboratory animal research. Your responses are crucial to the progress of this research project and will be treated with strict confidentiality.

Thank you for your support!
