LOL...we are well familiar with the "speed bump"...the problemwith kitty speed bumps is that, unlike their concrete counterparts, they "move around" when least expected....usually appearing in right in front of your feet as you are progressing forward in the dark in the middle of the night to the bathroom, the magic speed bump will position itself in front of one foot, then suddently in front of the other, matching your feet step for step until you either
a) accidentally step on the speed bump and make its alarm go off (A LOUD HORRIFYING SOUND) OR
b) you trip and fall trying to avoid option "a"
