Oh, and if you needed proof as to how fucking evil Heathcliff was, his first episode...
The Great Pussini
Kitty Kat Kennels
Now, there may be nothing inherently evil in what's going on in the cartoon (minus the annoying rhyme talk of one of the cats and the ungodly hotness of another), but look at the titles of the two segments. The Great Pussini? Kitty Kat Kennels? We're introducing our children to these characters via the seemingly innocent methods of pornography and the KKK. Fantastic.
Also, notice how this is the first episode, and it's already established that talking in rhyme and rhyme alone is incredibly annoying and will, in all likelihood, turn you into the bitch of a smarter cat who has a cooler hat than you.
