As I said in post 18 it has been shown that certain animals do have a sense of 'self'. It is the extent of this consciousness that is in question.
That said, it does seem that there is a questionable assumption often made that planning in humans is down to superior intellect, in 'animals' it is down to instinct!
I'm sure there is much work going on in this area of animal consciousness and psychology. An area I'd be really keen to explore further.
