Sorry but this is something that rather annoys me, as well as its a very biggest pet peeve of mine.
First things first, the word "Neko" means cat in Japanese, that's it. It does not mean a person with cat ears an a cat tail and it never did. The term for someone with Cat ears, Dog Ears, Wolf ears, Etc. Ears and tail ... is Kemonomimi which means literally translates into "Beast Ears" in Japanese.
Second thing I'd like to mention is, Kemonomimi was not even really or ever has tried to associate itself with the furry community, it originated as a style of Japanese animation normally to depict animal spirits in human form. A great example of this is, is the fact that before I even knew the furry fandom existed my original first ever OC was a Wolf Kemonomimi. So how can I be a poser if I don't even know what I'm posing as, Kemonomimi are a part of the "Otaku" fandom.
