I'm worried because the fights between kittens who don't like to lose are so intense

The kittens' wrestling game becomes more intense day by day.
Kitten Jera fights with her brothers with her small body.
Anyway, the speed at which it runs is increasing and it is difficult to follow it with a camera😅
