If you are travelling in the dark, you dilate your pupils into a perfect circle to catch the maximum amount of light. If you appear in daylight, your pupils go into an elliptical shape, to minimize the amount of light reaching the retina. My friend, you are knowledgeable about optics. When you leap you calculate the distance with unbelievable accuracy. You use the exact muscular effort required to traverse the distance. My dear cat you are a geometrician.

Christmas Bonus: Little furry angels are so very sweet, but God put razor blades upon their little feet.  A line from a poem that I remember but can't find. So apologies to the author.
