At first it appears that the cat was enjoying the light bouncing. When the child bounced harder the cat got increasingly distressed and near the end had its ears laid back. A cat's intestinal system isn't the same as a five year old child's to take all of that jostling. And you try to stand on your feet and get off a moving trampoline. I wonder if the mother would have kept saying "jump harder" if the girl's baby brother or sister were on that trampoline.
This is a stupid video. It seems the staff at neatorama have a mean streak when it comes to animals.
It would be nice if neatorama would move on from such basic "humor" to amuse themselves, and bring us something with more substance.
"no danger to cat" is not the same as "not mistreating cat".
