I and my fiance love nature shows. I'm currently eight months pregnant (twin boys) and I'm certainly more emotional than usual. There were parts in Planet Earth 2 that just made me sob like a baby. There was a female snow leopard with a 2 year old cub (almost an adult, but not quite yet independent). The mother was in heat again, which made things very dangerous for her cub, because adult males usually kill off a mother's offspring so that she's much more receptive to mating with them.There was a bit where two huge males wanted the mother - they harassed her viciously and the mother leopard did everything she could to save her cub from the males. She succeeded. And a month later the cub wasn't with the mother anymore - she had become a fully independent adult. When I watched it it made me cry and sometimes I still do when I think about it.
