Speaking as one who likes both cats and dogs more or less equally...
I'm sure you've all heard the story about the difference between cats and dogs.
People feed their dog, pet their dog, and otherwise care for the needs of the dog. The dog thinks, "Wow, they must be gods!"

I think that sometimes we prefer dogs because we see them in such a favorable light and hope others see us in a similar fashion -- i.e. humble, friendly, and fun to be around. And we dislike cats because they generally behave as we know ourselves to be -- i.e. proud, selfish, and barely tolerant of other beings.
