The sheet above shows Milt’s character designs. I like the loose skin under his chin and in the back of his neck, which provides opportunities for sqash and stretch. Milt loved working on scenes with Edgar, because his personality called for strong emotions, from deep frustration when he finds out that the cats will inherit Madam’s fortune, to gleeful excitement, when he believes that he has successfully gotten rid of the cats.
That particular situation is explored in these sketches by Ken Anderson, who came up with fun ideas that show Edgar in a self-congratulatory mood. - Andreas Deja
