A feudin' hillbilly cat and mouse? Oh, Hannah-Barbera, is there no derivative premise that you can't turn into a sub-standard cartoon?
Oh, Gold Key, was there no cartoon so lame and unheralded that you wouldn't make a comic book adaptation of it?
Oh, snell, is there no comic so obscure, so ridiculous that you don't have to own it?
The answer to all three questions, obviously, is "no."
The only issue ever of Mushmouse and Punkin Puss was from 1965
