I will often get up in the morning to find a couple of rabbits sleeping in the yard and in the summer I am constantly sweeping turds off the sidewalk.
But during the almost two week cold snap that we had recently, those rabbits were nowhere to be found. And since the Slightly Retarded Kitty was also not interested in venturing outdoors, the thick layer of snow that had descended upon the yard was absolutely unmarked, virginal, pure as .. well, as the driven snow.
Now that the temperature has returned to more seasonal values, there are rabbit tracks all over the yard. I think they've been having a barn dance, to celebrate their return home.
