I have an idea for a 1920s-style cartoon in which there's an assembly line where a bunch of cats are fed shovelsful of tobacco and then poop out perfectly rolled cigars, which we later see being smoked by wealthy dogs wearing top hats, monocles, etc. while everyone around them reacts in disgust.
@JolieSaboteuse Yes, a visual reference to that could be included in the cartoon.
@SteveCarll67 Sounds like "Dogs playing poker".
