A kitten rescued by a parent cat where she falls on a slide, but then a tragedy will occur

A movie of a parent cat watching a kitten falling without climbing the slide and going to help with Switzerland. The kittens, which seemed to fall first, were safely rescued, but that state is supposed to drive another kitten to an unexpected result.

Details are as below.

A parent cat appears there.


I walk to Switzerland as if there are no slopes and go to the kittens place and I have a neck in my head.


I took a kittens as it was and climbed the slide.


At last I thought that the parent cat helped the kitten, another kitten following the parents began to slide down.


A little cat falling down the slide with slurping. Does your parents catch up with the first cats you rescued, there is no sign of coming to help.


I could not stop until the end and it fell down.


I do not see any injuries because there are not so many steps, but I wonder if I could have returned to the parent cat ... ....?
