I don’t think this woman could have predicted her cat’s reaction to this form of play unless the video was carefully orchestrated and she knew exactly what would happen. It makes an interesting little video and sometimes people create these videos deliberately. The cat is not feral as indicated in the words below the video. It does not take a feral cat to do this. You just have to push the right button in a cat’s head and voila, the wild cat comes out to get you. I hope she wasn’t hurt.
We know that cat play is a substitute for hunting so there are claws and teeth involved supported by rapid movement!
