Mice are nocturnal animals, meaning they are active at night and sleep during the day. As such, it is important to provide them with an environment that mimics their natural behaviors and rhythms. This includes maintaining appropriate light levels in their cages. However, studies that have looked at this noted large variance in lighting among different facilities, and even cages within the same facility (Castelhano-Carlos and Baumans, Laboratory Animal, 2009).
Proper lighting is important for the overall health and well-being of mice. Inadequate lighting can lead to a range of health problems, including obesity, reduced immune function, and abnormal behaviors. On the other hand, excessive lighting can cause stress and disrupt their natural sleep-wake cycle.
To ensure the health and happiness of mice, it is important to monitor the light levels in their cages. This can be done with the Pallidus MR1. By regularly checking the light levels in the cage, you can ensure that the mice are receiving the appropriate amount of light, that lights are being controlled on the proper cycle, and that light disturbances (such as people turning on lights after hours) are identified.
