Look, gerbil: We're really happy that you're having a good time and getting lots of exercise, but could you keep it down?!
Don't resent your pet for playing in the middle of the night, give her a Super Pet Silent Spinner Wheel ($12-14). Now she can run in circles for hours and you won't give a damn because you won't hear a peep.
