If there was kemonosume in real life, they would try to hide their exist to public. To live a normal life without one noticed their ears and tail, after some analysis, I conclude that they would wear stetson hat and wrap their tail with specially designed pants.

So thats why when you see a person wearing stetson hat and wearing large jeans, there is a around 0.001% chance that you are seeing a kemonosume. If you want to find one, going to texas maybe a good idea.
