The Pain (aka Jake Porter) is six years old. His sister, The Great One (aka Abigail Porter), is eight. Like any siblings they drive each other crazy. In "Friend or Fiend?", it's Fluzzy's birthday and Jake and Abigail want to throw the best party any cat has ever had! But it's not long before they start fighting, and it takes a seriously sticky ice-cream incident for them to make-up.
