Trivia

 * The last line in the letter is a reference to the Warner Brothers character Pepé Le Pew and his love of a black cat who usually has a strip of white paint poured down her back making her look like a "skunk".
 * When a Black Tabby, Calico Cat or Bombay Cat is summoned in the presence of Stinker, a heart will appear over Stinker's head and he will begin chasing the cat, which is a reference to Pepé Le Pew (and Penelope Pussycat).
 * The "Shop Smart, Shop Pet...Smart" achievement name is probably a reference to the real world pet store, Petsmart. Their motto is verbatim of the motto of Reeking Pet Carrier. It could also be a reference to the movie "Bruce Campbell vs. The Army of Darkness", where Campbell's character works at a fictional store called S Mart.  Their motto is "Shop Smart, Shop S Mart."
