They don't hide the fact that they're yinrih if the topic arises naturally, but sometimes they want to be able to mingle without the fact they're the only sapient nonhumans on Earth getting in the way.

They all have usernames that reflect their understanding of human culture. Not sure what the others are, but Tod's is definitely zorrito_dorito.
