Well, what if those mice are completely out of their minds? Discover recently ran an article showing that mice kept in a standard laboratory environment may be crazy. 'In one sequence, a mouse climbs the stainless-steel walls of its cage, hangs from the ceiling by its forelegs while gnawing on the bars, then drops to the floor, only to repeat the process endlessly. On the other side of the cage, a second mouse performs backflips, one per second, for up to 30 minutes at a time.'"
