Sometimes I can swear that our pet cat is dreaming in her sleep: her jaw kind of sags, her breathing becomes sleep-like (almost audible), she has tiny jerks in her paws and arms, her whiskers tremble. During these times, she is in a deeper kind of sleep than her more frequent "cat sleep"...

I think one of the most important questions facing those would adopt the Dennettian approaches of "Multiple Drafts" and "heterophenomenology" is: Why -- if there really is no "finished product" of conscious perception, no "quale", no quantized "perception" -- does it seems so intuitive to refer...

As we all know, animal can communicate with each other with body language, sounds, etc. just like human. But does every animal of the same species communicate the same way? For example, are cats in different areas communicate the same way?
