Within Leiden University, we sometimes conduct research with laboratory animals. We only do this when when we cannot answer the research question in any other way.

Research using laboratory animals always takes place under very strict conditions set by law. The research is monitored both internally and externally. Transparency about research involving animals is guaranteed through the Transparency Agreement on Animal Testing (page in Dutch).
