Scientists create rodents that are more active, more aggressive, and live longer than ordinary mice. Exterminators are unhappy.
  • Higher metabolism = needs more food

    My guess is that because these mice have a higher metabolism, they will require that much more food to stay alive. Therefore, in situations with abundant food, super-mice are more competitive. But, in situations where food is scarce, I would bet that normal mice would out-perform the super-mice.
