The Fan mail short

Remember how Nickelodeon used to always play this around the time the show first aired? I looked up the episode on Kisscartoon and I remembered it like it was yesterday. lol. At the time, I thought you could actually send them fanmail but I was in 4th grade and still pretty naive.
Why would Winslow not tell Catdog about the huge amount of letters?
