Okay but where does her tail connect to the spine?!
I'm going to preface this by saying I am not a biologist, or veteranarian, or have any information aside from what I found on google after some very cursory searches. So if I'm wrong, please educate me.
So on a cat, the tail (caudal vertebrae) connects to the sacrum on the pelvis like so.
On a human, we might expect the tail to connect to the coccyx (tailbone) which is slightly below the sacrum.
So on a cat person, does it connect to the sacrum or the coccyx? And if it connects to the sacrum, does Izutsumi still have a coccyx like a human? If it connects to the coccyx, is that comfortable? Does it affect balance? There are many small but interesting implications of this.
Ryoko Kui put out some sketches from her early work, but it doesn't seem to clear things up very much.
If anyone can say why it might be one or the other, please give me your thoughts. Also, because everyone loves a poll:
Where does Izutsumi's tail connect to her spine?
Coccyx (like a human)
Sacrum (like a cat)
