Another thing: it's not every day that you can say that there was a more violent cat and mouse team than the infamous Tom and Jerry. Everyone, meet Herman and Katnip. These cartoons are played out like a T&J cartoon, only there are far more brutal jokes like one where Herman brushes Katnip's teeth with a metal file, or pounding Katnips head so hard with a mallet that it actually leaves an imprint. Aside from that, Katnip's little strut when he thinks he catches Herman is hilarious.
On top of that, the voice acting is pretty stellar. Mae Questal relives her moments as Betty Boop and Sid Raymond is always a riot. Arnold Stang also appears in this cartoon and does a good job. I personally like his Top Cat voice better, though. Oh well. :)
I wish I could present this in a higher quality than what I have, but these are incredibly hard to find.
