In a recent Guardian live chat, the frequently-entertaining pop philosopher Slavoj Zizek added his two cents:
What do you think we can learn from cats, if anything?
Nothing. I like to search for class struggle in strange domains. For example it is clear that in classical Hollywood, the couple of vampires and zombies designates class struggle. Vampires are rich, they live among us. Zombies are the poor, living dead, ugly, stupid, attacking from outside. And it’s the same with cats and dogs. Cats are lazy, evil, exploitative, dogs are faithful, they work hard, so if I were to be in government, I would tax having a cat, tax it really heavy.
Much, much more Dish discussion of dogs vs cats here.
