inumimi or something else, I can't really tell

is there some word for foxears, that might be more accurate

It's Meganeko's work as said in the corner. it's not in my book (E=MC2 illustrations, the one with the cute neko girl standing on one leg with her hand on her knee in a pink outfit.)

and to the poster above, i believe the word you are looking for is "Kitsune"

Added the Meganeko tag.
