Mom lion is behind the log about center, and her male cub is just to the left under the bushes (by the red cone) in this shot.
Viewers are behind tall thick glass, or at the very edge of the glass you can carefully shoot
through some mesh fencing with openings about the size of a camera lens.
So different to the concrete cages and iron bars. My mother refused to take me to the Zoo again after seeing the lions pacing back and forth in their small space, gazing out over and above the viewing public.
