Animal Bill of Rights

[Catherine]

Put very simply, sentience is being aware.  You feel, perceive and experience subjectively.

I think of it as being aware of your own existence. You feel things and you know that you feel things.
A rock is cold. That is it, the rock is cold. I am cold, I know that I am cold. I know that I don't like being cold. I might even be able to do something about it. But first, I know that I am cold.

We can't deny that animals are aware. Most people will at least admit that they can feel.
