Mice have a strong preference to nest away from their own waste, new research has found. The study showed that mice who were housed in a system of three interconnected cages used separate cages for nesting and eliminating waste. Typically, laboratories house mice in close proximity with their excrement. The study suggests this compromises their welfare and may also negatively affect research data.
