I'm planning on posting my story here and on my FA account as soon as I'm about 90% complete with it. Right now, I'm going through a bit of melancholy due to losing my cat to cancer a couple of weeks ago. It happened so suddenly that I didn't have time to prepare for it. She was fine a month before she died, running down the hallway and stopping in front of me when it was dinner time. Four weeks later, she's lying on my bed crying in pain for an hour before she died. I'm working on a little story to tell of our life together and then, I should have exorcised the demons of her death and I can return to my story of Amanda.
As for Amanda's family name, an artist here who's from Germany said she looked more like a lynx and I should have given her the family name of Luchs, German for lynx. After I explained her family history, he understood why her name is Fox.
Almost every anthro character in my story has a family name that means their "species" in a language other than English. I have a badger character whose name is Anaguma (Badger in Japanese), a dog character whose name is Sobaka (Dog in Russian), a bear character whose name is Bjornson (Bear's son in Swedish), and a Serval character whose name is Tierboskat (Serval in Afrikaans), to name a few. If I ever run out of languages to use, I'll just do alterations of the original name, i.e. foxfire for a fox, wolfsbane for a wolf, etc. I most definitely WON'T run out of family names. Of course, I could do like the English and make one name common to numerous different, unrelated families. LOL.
Oh, BTW, I think your friend is wrong. Von Vulpiloupus doesn't look like a mixture of Greek and Latin; it looks like a mixture of German, Greek and Latin. LOL. (Von is German for from or of.) Loupus, I believe comes from the Latin word lupus which means wolf and Vulpi is a corruption of the "tribe" of canids, vulpini, that the fox belongs to. (I had to Google THAT one up. LOL.) Vulpini sounds Latin to me, though.
