A video of a cat getting stomped on 3 girls. They kept stomping on the cats body, when it died the girls was still stomping on the body to flatten out the organs.
A cute-looking chick with cat ears, a tail, and maybe paws and a few patches of fur. Catgirls usually act rather cat-like and always succeed in being very very cute and sexy.
If they were ever real (Even if it was just one) every anime fan in the world would likely honour her as some sort of god or ruler of the planet in a matter of days after the existence was proven.
All world order would crumble and rise from the ashes within a matter of days with everyone following the one Catgirl (Probably more but who cares one would be enough to do this) to lead us all into a new era that would be like it is now but just much nicer knowing that your ruler of the world was a catgirl or catgirls
Anime fan: A Catgirl exists
Every Anime fan in existence: Hail to the new Catgirl ruler of us all!!!!!! *All politics of the world crumble in one beautiful moment*
