This guy.
About 4 years ago my girlfriend and I were walking our dog Luna, there was a storm on its way and it was looking serious. We live in tornado alley and it was that time of year too. After a while we notice a little kitten following us, he looked too young to be away from his mother. Luna started barking at the poor kitty like crazy, but to our surprise the little guy didn't even care! He just stared at us and meowed, as if he was saying "Take me home with you! Save me from this storm!", so we did. Now, him and Luna are best friends (of course), and he is the king of the neighborhood, and all the cats wish they were Pazu ;)
Pazu is named after the main character in Studio Ghibli's movie "Laputa, Castle in the Sky" because he has an adventurous personality.
