Here's this little guy all grown up, giving me a fist bump! This was taken about a month ago...as you can see, he's kind of kitten-like even as an adult cat.
(Full disclosure: He gets a tasty snack after high-fives and fist bumps, usually his favorite, Temptations Surfer's Delight. I learned how to make my cat sit on command, high five, fist bump, walk on a harness and other things thanks to Robert Dollwet, aka "CatManToo."
