Your cats don’t want to vote in the next election, and so women shouldn’t either. This was the argument of the anti-suffragists in the early 1900s:
"Cats were a common symbol in suffragette imagery. Cats represented the domestic sphere, and anti-suffrage postcards often used them to reference female activists. The intent was to portray suffragettes as silly, infantile, incompetent, and ill-suited to political engagement."
