Research with laboratory animals

At Leiden University, for some of our research we use laboratory animals. We conduct this research in a responsible way and only when there is no other viable alternative. We ensure the best possible quality of life for the animals and uphold high standards for the quality of the research. In this dossier you can read how we do this.

Why do we use laboratory animals?

We use laboratory animals to answer research questions. However, we do so only when there is no alternative, and we cannot answer a question in any other way. Read here why we conduct animal experiments.
