I enjoyed the nice story with science and language.
"neko o kaburu" (put a cat on one's head = to feign innocence)
"attemo nakutemo neko no shippo" (have or have not, a cat's tail = doesn't matter)
You want cats with no tails try the Isle Of Man (Small island between UK and Ireland) The manx cat is a breed that doesn't grow a tail. Smaller than your average cat they are a strain native to the island.
LMAO. Forgot about this. I can't read the story now, but does it mention the other deformed tails? Loads of Japanese cats not only with 'nubs' but with also some crooked stuff going on.
