Update - absolutely nothing going on at the moment
seriously.
Usually it is Hazel sitting on the box edge though from time to time Pandemic comes in.
Sometimes Hazel wanders inside to fiddle a bit with the gravel (no massive rearrangement like Princess or Ella)
Very occasionally Pandemic turns up with a snack, Hazel snatches it away - sometimes she stays and eats on the box edge, sometimes she heads off elsewhere.
What is annoying about this pair is that except for sitting on the box or sometimes on the sign before they do not sit anywhere within range of the cameras - frustrating to the nth degree.
It is a waiting game ... I haven't seen any hanky-panky but every morning my fingers are crossed when I check the cam!
