Having a little species and color trouble. I was looking up Jinx and it said the word Jinx comes from the Jinx bird that were used in magic. So I was thinking about a Nightmare Lain? Thoughts?
For some reason, a white kittycat comes to mind for me (blame it on some friends of mine...), so my suggestion is an Arid Feli.

I think a Nightmare Lain would work indeed pretty well for the name since "jinx" also can be associated with bad luck as far as I know. C:
