What do you think goes through a cat's mind?

        How does a cat view the world? How do you think a feral (as opposed to a domestic) cat would view the world, or vice vera? What do you think would be an appropriate obstacle for them to overcome?
        I don't know of a cat who ever used a can opener, but I remember a news program 20 years ago in Massachusetts where some fellow made a special seat to go over the toilet and then potty-trained his cat.
        There are other cats, like Mewling (rest his furry little soul) who by trial and error learned to open screen (and even cabinet) doors.
        Cats are as alien to us as any extraterrestrial creature. They're the same basic life form as us (mammals), but their society and civilization, even when shared with their human pets, are very different from homo sapiens.
