Figure 3. Different nestlet shredding activity in the home cage versus a fresh cage.

The same cohort of mice (n = 8) was exposed to the nestlet shredding test in a cleaned cage filled with fresh bedding (“fresh cage”) and, one week later to exclude habituation to the task, in their home cage. Connected data points derive from the same test animal. Note that the same shredding score (0 g in the fresh cage and 0.1 g in the home cage) was reached by three different mice. Statistical analysis was performed using paired Student’s t test. *p < 0.05
