Puzzle time!

Find the odd one out.

Another afternoon Mabel-sitting while Lulabel helped at an all-day Boogie training session. She likes to sit on the window-sill and watch the world go by. (Mabel, not Lulabel) It's also nice and cosy up there, above the radiator.

I'm enjoying the latest David Attenborough series, "Dynasties". As always the photography is amazing.
