Seen out the window

This is Ruby in front of St. Francis.  What is she so interested in?  St. Francis or the burrows in the mound behind him?  But she stayed there quietly for ten minutes or so.  Such concentration!
Ruby, Ruby Begonia is her full name, adopted us one day maybe 7 or 8 years ago as we walked our road.  She was very little and came toward us crying.  When we heard a car coming, we scooped her up and she stayed in my arms the half mile to home.  She has been with us ever since, but is our most outdoor cat, taking every opportunity to roam far and wide, except when winter finally gets her down, or in, to be more correct.
