You have all seen a cat gently and agilely hop down from a shelf,chair,window,etc during the day making hardly a sound. So why is it that as soon as the lights go out and you're all snuggled down the same cat jumps from the same place,,and lands with the velocity,weight and SOUND of a 5 ton elephant dropped from a 50 story building??? Do cats get heavier at night?? Does sound amplify in the dark?? Am I the cutest,sexiest...oop,scratch that last one,I already know the answer.
