To restate an old religious joke, dogs are Christians – they believe in you no matter what you do. Cats are Pagans – they want to see the food in the bowl.
On an only slightly more serious note, I continue to be amused at how many Pagans and Wiccans have cats (and/or dogs, but especially cats). I think there’s something about the Pagan aesthetic of finding your own path and doing your own thing that means we relate well with cats.
Again, it’s not that Pagans can’t love dogs, but perhaps the old stories of the witch and her familiar cat are playing themselves out in the contemporary world for very good reasons…what do you think?
