My screen name used to be "foxfirekit" from
"fox fire" the magic move that Shippou (yes, from inuyasha) does, and
"kit" is a term for a baby fox or cat etc..
since foxfirekit is too long people called me kit and it stuck.
If Kit isn't available (and it usually isn't on popular sites), and it won't let me use k-i-t, I use "Snoleopurrd" because Snow Leopards are my favourite animal, and that strange spelling will never be taken already, so it's original!
