It’s unfortunate that you occasionally read about stories where humans abuse animals, but sometimes animals can abuse and torment people right back. In the above video, you can see a cat stopping someone from stepping into the room.
Why a cat would be so angry at someone remains a mystery. Perhaps the person reminds the cat of someone mean, or perhaps the cat can sense that the person is someone evil after all. If cats can sense evil people, perhaps we should let them help us choose our next politicians.
