Sorry, I was not totally clear on my definition of self aware I think. I agree with MariaHobbit that most animals are self aware in that they have an awareness of self. You cannot be around most higher beasties (I do hate that phrase but consider it to mean mammels, birds, reptiles, some fish, amphibians, ceplapods and a few others) without noticing that they are aware of thmselves as seperate beings and thier place in the world.
I was not sure what level of self awareness though we were using here. there is a huge gap between 'me' and 'I think therefore I am'. I am not sure that 'abstract thought' covers it, mainly becaue I am not sure how you define that, what constitues that or what level of abstraction would dictate intelligence.
Most abstract thought paterns, by definition, are abstract from human norm. How can we use such patterns to judge animals?
For example, a dog that pulls on a table cloth to drag food onto the floor is probably using instict, but if he uses his paws to open a door handle is he using abstrct reasoning, or mimicking? A crow that bends a piece of wire to use as a tool to pick a bean out of a jar is using abstract thought, a man sitting by a pc who uses the phone to order pizza is using training.
