And no rat killing? I am disappointed! Kidding, I know it's to observe behavior, not to make tests on them (although it would be fun if you had a bioluminescent rat to see how that abnormal characteristic would reflect on its behavior and its relationship with the others... and green glowing rats are always cool).
