Ensuring positive emotional well-being in laboratory animals is crucial for both their welfare and the integrity of scientific research. By refining handling techniques and providing positive reinforcement, we can enhance their overall experience in laboratory settings. Recent studies highlight animals’ ability to detect human negative emotions, emphasizing the importance of cross-species social cues. Research led by Prof. Emma Robinson’s group has pioneered objective methods to measure animals’ emotional states, offering valuable insights into their experiences during various interventions. One particularly promising finding is the use of ultrasonic vocalizations emitted by rats as a measure of their direct emotional experience. This innovative approach holds the potential to streamline the assessment of animal welfare without the need for extensive resources or equipment, marking a significant step forward in research and veterinary practices.
